2 Deepwell cargo pumps 2.1

Introduction The Marflex deepwell cargo pump is a range of electrically driven, vertical single stage centrifugal pumps, each type of pump has a specific performance range. The special multiple, modular stack design (with non cargo lubricated drive shaft) allows for immersion depths up to 40 meters. The Marflex deepwell cargo pumps can be divided into two different types, which differ in their drive shaft layout. First the most specific differences between the two types will be explained, followed by a general explanation of the pump layout which is identical for both types.

2.2

Marflex Deepwell Pump Double, type MDPD The drive shaft is located next to the cargo transportation pipe in the pipestack. The picture on the left shows the pumphead with a part of the pipestack. This layout is used for the smaller types of Marflex deepwell cargo pumps.

2.3

Marflex Deepwell Pump Concentrically, type MDPC The drive shaft is located inside the cargo transportation pipe in the pipestack. The picture on the left shows the pumphead with a part of the pipestack. This layout is used for the larger types of Marflex deepwell cargo pumps.

0301v0_2.fm Project: 18070051

Section 3 2-1

General layout

2.4

General layout The Marflex deepwell cargo pumps are equipped with a “oil lubricated drive shaft” running in a separate supporting pipe. The service life of this ‘oil lubricated drive shaft arrangement’ is more than 10.000 running hours and is based on the service life of the bearings in the electric motor. The 10.000 running hours are normally sufficient to last the lifespan of a sea-going vessel (20-25 years). To explain the Marflex deepwell pump in details we divide the total pump layout in 5 sections: Electric motor Top cover Deck trunk Pipe stack Pump head.

2.2.3

Precautions and preparations Danger! The purge outlet must ALWAYS be open and connected to ambient! Caution! It is NOT allowed to connect the purge inlet permanently to an air or nitrogen source! Caution! Use ONLY clean / dry nitrogen or air when purging a deepwell pump! Caution! Use the Marflex supplied purge set to clean the air or nitrogen and to reduce the pressure to a maximum of 3,5 bar. To only reduce pressure a Marflex supplied pressure reducer and relief valve can be installed on each pump’s top cover. Note: A dirty / polluted air- or nitrogen supply system affects the purge results. Prepare an air or nitrogen source to connect to the purge inlet of the pump’s topcover. Make sure used hoses are not polluted by products.

Determine the pump’s top cover layout. When no pressure reducer and relief valve (see 2.5.2) is installed on the top cover the Marflex supplied purge set (see 2.5.1) must be used!

System setup (typical) Caution! To prevent contamination of the ships air system it is not allowed to connect the purge inlet directly to the ships air system. Use the Marflex purge set to connect the ships air / nitrogen system to the purge inlet and connect the purge set to the purge inlet quick coupling. The purge set reduces the pressure (max. 3,5 bar), cleans the air / nitrogen and separates from the ships air / nitrogen system. The content from the cofferdam is collected using several methods depending on the cargo carried. System set-up (typical)

2.2.5

System setup with headertank Caution! To prevent contamination of the ships air system it is not allowed to connect the purge inlet directly to the ships air system. In a pump system equipped with a headertank the cofferdam and the purge pipes are completely filled with oil or a special, cargo soluble, liquid. Monitor the level through the sight glass in the headertank to get an indication of the condition of the shaft seals. Blow through using the purge set to remove the oil from the system. Collect the oil from the cofferdam and purge pipes in a suitable container for inspection and analysing. Refill the system with oil using the membrane pump (max. air press. 1.5 bar).

2.2.6

System setup with a closed circuit purge unit Danger! Make sure to follow the operating instructions of the closed circuit purge unit to prevent injury and / or damage! A closed circuit purge unit is delivered with distinct user instructions. A closed circuit purge unit is used when transporting dangerous, poisonous or aggressive cargo. Using this unit prevents contact with the cargo when carrying out a purging routine. The result of the purging routine is visible through a sight glass on top of the unit when operating the pump inside the unit. The collected purge results in the closed circuit purge unit are drained in a slop tank or a drum using the pump inside the unit. System set-up with closed circuit purge unit

2.3

Inspection and reports Tip. Acurate recording of purging results allows for close monitoring of the pumps condition and anticipating maintenance schedules. Collect the contents of the cofferdam in a suitable container or sample bottle. Inspect the presence of lubricant or cargo and observe the limits using table 2.2.2. Register the results on a "Purging report form" (see 2.5.3 for an example). Send the results regularly to the Marflex service department (mail, fax, e-mail or Chembase). A “Pump seal monitoring” computer program (Chembase) can be obtained from Marflex and gives the oppertunity to send the results to Marflex directly through e-mail.

Section 4 2-5

Monitoring shaft seal and oil condition between purge intervals

2.4

Monitoring shaft seal and oil condition between purge intervals Note: Be aware that the ships trim position has an effect on the indication of the oil level! During the time between two purge actions the condition of the shaft seals and the condition of the lubricating oil can be monitored. By observing the oil and the oil level through the sight glass in the top cover (see figure) these conditions can be determined. Changes in oil level, discoloration, foaming or otherwise can indicate a possible problem in the pump. Record the oil level when starting monitoring. Table 2: shows some possible causes and solutions when monitoring the oil.

3 Stripping routine 3.1 3.1.1

Stripping of the tanks Description During the last stage of cargo offloading, the pump starts to pump air, the current (Amps) drops (discharge pressure drops) and a certain amount of cargo is left in the pump well and pipe stack. To remove as much of the remaining cargo as possible and to clean the cargo discharge pipe a stripping procedure is carried out. This procedure reduces the amount of remaining cargo in the pump well to a minimum. Present and future IMO rules are hereby achieved. Pressurized air or nitrogen is blown through the main cargo discharge pipe and, with an operating deepwell pump, pushes the remaining cargo through the stripping pipe out of the tank. The pump is kept running until the cargo pipe is empty. In general it will not take more than 2 – 5 minutes to carry out the stripping procedure, depending on the dry run limitations, the size of the pump and pump well, . For the quantities of cargo remaining in the tank after stripping see Table 1.

3.1.2

Remaining cargo after stripping Note: The quantity of the remaining cargo largely depends on the size and shape of the installed pump well in the tank. Table 1: Remaining cargo Type of pump

Stripping of the tanks

3.1.3

Procedure Caution! The Marflex Deepwell pump is allowed to run dry for a limited period (normal ± 1 minute, max. 3 minutes)! To prevent unnecessary wear on seals and wear ring do not let the pump operate dry longer than necessary to remove the remaining cargo because the pump is then no longer lubricated and cooled by the product (cargo). Tip. Make sure the main discharge line to the manifold is empty before stripping. An empty main discharge line prevents unneccesary pressure build up and improves stripping results.

1. When the cargo tank is empty at the end of the normal discharge procedure, close the main cargo valve 2. Stop the cargo pump 3. Connect the air / nitrogen pressure source to the stripping air inlet coupling (with a flexible hose) 4. Check the pressure of the air / nitrogen supply (min. 6 bar) 5. Start the cargo pump (cargo is pumped through the stripping valve) 6. 7. Open the stripping valve when (cargo) pressure is rising 8. When the cargo tank is empty open the air / nitrogen supply control valve to supply pressure to the stripping air inlet coupling 9. When the remaining cargo is removed close the stripping valve 10. Stop the air / nitrogen pressure supply 11. Repeat step 7. through 10. if neccesary 12. Stop the cargo pump 13. Disconnect the pressure source.

SECTION 2

THE WILDEN PUMP — HOW IT WORKS The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow pattern through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.

RIGHT STROKE

MID STROKE

LEFT STROKE

FIGURE 1 The air valve directs pressurized air to the back side of diaphragm A. The compressed air is applied directly to the liquid column separated by elastomeric diaphragms. The diaphragm acts as a separation membrane between the compressed air and liquid, balancing the load and removing mechanical stress from the diaphragm. The compressed air moves the diaphragm away from the center block of the pump. The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm. Diaphragm B is on its suction stroke; air behind the diaphragm has been forced out to the atmosphere through the exhaust port of the pump. The movement of diaphragm B toward the center block of the pump creates a vacuum within chamber B. Atmospheric pressure forces fluid into the inlet manifold forcing the inlet valve ball off its seat. Liquid is free to move past the inlet valve ball and fill the liquid chamber (see shaded area).

FIGURE 2 When the pressurized diaphragm, diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurized air to the back side of diaphragm B. The pressurized air forces diaphragm B away from the center block while pulling diaphragm A to the center block. Diaphragm B is now on its discharge stroke. Diaphragm B forces the inlet valve ball onto its seat due to the hydraulic forces developed in the liquid chamber and manifold of the pump. These same hydraulic forces lift the discharge valve ball off its seat, while the opposite discharge valve ball is forced onto its seat, forcing fluid to flow through the pump discharge. The movement of diaphragm A toward the center block of the pump creates a vacuum within liquid chamber A. Atmospheric pressure forces fluid into the inlet manifold of the pump. The inlet valve ball is forced off its seat allowing the fluid being pumped to fill the liquid chamber.

FIGURE 3 At completion of the stroke, the air valve again redirects air to the back side of diaphragm A, which starts diaphragm B on its exhaust stroke. As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. This constitutes one complete pumping cycle. The pump may take several cycles to completely prime depending on the conditions of the application.

PRO-FLO™ AIR DISTRIBUTION SYSTEM OPERATION — HOW IT WORKS Figure 1

WILDEN PUMP & ENGINEERING CO.

The Pro-Flo™ patented air distribution system incorporates three moving parts: the air valve spool, the pilot spool, and the main shaft/diaphragm assembly. The heart of the system is the air valve spool and air valve. As shown in Figure 1, this valve design incorporates an unbalanced spool. The smaller end of the spool is pressurized continuously, while the large end is alternately pressurized and exhausted to move the spool. The spool directs pressurized air to one chamber while exhausting the other. The air causes the main shaft/ diaphragm assembly to shift to one side — discharging liquid on one side and pulling liquid in on the other side. When the shaft reaches the end of its stroke, it actuates the pilot spool, which pressurizes and exhausts the large end of the air valve spool. The pump then changes direction and the same process occurs in the opposite direction, thus reciprocating the pump.

CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump should be disconnected and all air pressure allowed to bleed from pump. Disconnect all intake, discharge and air lines. Drain the pump by turning it upside down and allowing any fluid to flow into a suitable container.

CAUTION: Blow out air line for 10 to 20 seconds before attaching to pump to make sure all pipe line debris is clear. Use an in-line air filter. A 5μ (micron) air filter is recommended.

CAUTION: When choosing pump materials, be sure to check the temperature limits for all wetted components. Example: Viton® has a maximum limit of 176.7°C (350°F) but polypropylene has a maximum limit of only 79°C (175°F ).

NOTE: Tighten clamp bands and retainers prior to installation. Fittings may loosen during transportation. NOTE: When installing Teflon® diaphragms, it is important to tighten outer pistons simultaneously (turning in opposite directions) to ensure tight fit.

CAUTION: Maximum temperature limits are based upon mechanical stress only. Certain chemicals will significantly reduce maximum safe operating temperatures. Consult engineering guide for chemical compatibility and temperature limits.

NOTE: Before starting disassembly, mark a line from each liquid chamber to its corresponding air chamber. This line will assist in proper alignment during reassembly.

CAUTION: Always wear safety glasses when operating pump. If diaphragm rupture occurs, material being pumped may be forced out air exhaust.

CAUTION: Verify the chemical compatibility of the process and cleaning fluid to the pump’s component materials in the Chemical Resistance Guide. (see E4).

WARNING: Prevention of static sparking — If static sparking occurs, fire or explosion could result. Pump, valves, and containers must be properly grounded when handling flammable fluids and whenever discharge of static electricity is a hazard.

NOTE: Plastic series pumps are made of virgin plastic and are not UV stabilized. Direct sunlight for prolonged periods can cause deterioration of plastics. NOTE: Carbon-filled Acetal pumps are shipped with a grounding strap. The strap is attached to the manifold clamp band bolt. This strap must be attached via the clip to a proper grounding point.

CAUTION: Do not exceed 8.6 Bar (125 psig) air supply pressure.

CAUTION: The P.025 pump is not submersible.

SECTION 7A

INSTALLATION The Pro-Flo™ model P.025 has a 6.35 mm (1⁄4") inlet and 6.35 mm (1⁄4") outlet and is designed for flows to 18.7 l/m (4.8 gpm). The P.025 Plastic pump is manufactured with wetted parts of pure, unpigmented PVDF, carbon-filled Acetal, or polypropylene. The center section of the P.025 Plastic is constructed of virgin Acetal or polypropylene. A variety of diaphragms and O-rings are available to satisfy temperature, chemical compatibility, abrasion and flex concerns.

4. PIPING: Final determination of the pump site should not be made until the piping problems of each possible location have been evaluated. The impact of current and future installations should be considered ahead of time to make sure that inadvertent restrictions are not created for any remaining sites. The best choice possible will be a site involving the shortest and straightest hook-up of suction and discharge piping. Unnecessary elbows, bends, and fittings should be avoided. Pipe sizes should be selected so as to keep friction losses within practical limits. All piping should be supported independently of the pump. In addition, the piping should be aligned so as to avoid placing stresses on the pump fittings.

The suction pipe size should be at least 6.35 mm (1⁄4") diameter or larger if highly viscous material is being pumped. The suction hose must be non-collapsible, reinforced type as the P.025 is capable of pulling a high vacuum. Discharge piping should be at least 6.35 mm (1⁄4"); larger diameter can be used to reduce friction losses. It is critical that all fittings and connections are airtight or a reduction or loss of pump suction capability will result.

Flexible hose can be installed to aid in absorbing the forces created by the natural reciprocating action of the pump. If the pump is to be bolted down to a solid location, a mounting pad placed between the pump and the foundation will assist in minimizing pump vibration. Flexible connections between the pump and rigid piping will also assist in minimizing pump vibration. If quick-closing valves are installed at any point in the discharge system, or if pulsation within a system becomes a problem, a Wilden SD1⁄2 Equalizer surge dampener should be installed to protect the pump, piping and gauges from surges and water hammer.

INSTALLATION: Months of careful planning, study, and selection efforts can result in unsatisfactory pump performance if installation details are left to chance. Premature failure and long term dissatisfaction can be avoided if reasonable care is exercised throughout the installation process. LOCATION: Noise, safety, and other logistical factors usually dictate that “utility” equipment be situated away from the production floor. Multiple installations with conflicting requirements can result in congestion of utility areas, leaving few choices for siting of additional pumps.

When pumps are installed in applications involving flooded suction or suction head pressures, a gate valve should be installed in the suction line to permit closing of the line for pump service. The P.025 cannot be used in submersible applications.

Within the framework of these and other existing conditions, every pump should be located in such a way that four key factors are balanced against each other to maximum advantage.

If the pump is to be used in a self-priming application, be sure that all connections are airtight and that the suction lift is within the model’s ability. Note: Materials of construction and elastomer material have an effect on suction lift parameters. Please consult Wilden distributors for specifics.

1. ACCESS: First of all, the location should be accessible. If it’s easy to reach the pump, maintenance personnel will have an easier time carrying out routine inspections and adjustments. Should major repairs become necessary, ease of access can play a key role in speeding the repair process and reducing total downtime.

Pumps in service with a positive suction head are most efficient when inlet pressure is limited to .4–.7 Bar (7–10 psig). Premature diaphragm failure may occur if positive suction is .7 Bar (10 psi) and higher.

2. AIR SUPPLY: Every pump location should have an air line large enough to supply the volume of air necessary to achieve the desired pumping rate (see pump performance chart). Use air pressure up to a maximum of 8.6 Bar (125 psi) depending on pumping requirements.

THE MODEL P.025 WILL PASS .4 MM (1⁄64") SOLIDS. WHENEVER THE POSSIBILITY EXISTS THAT LARGER SOLID OBJECTS MAY BE SUCKED INTO THE PUMP, A STRAINER SHOULD BE USED ON THE SUCTION LINE.

Sound levels are reduced below OSHA specifications using the standard Wilden muffler element.

CAUTION: DO NOT EXCEED 8.6 BAR (125 PSIG) AIR SUPPLY PRESSURE.

3. ELEVATION: Selecting a site that is well within the pump’s dynamic lift capability will assure that loss-of-prime troubles will be eliminated. In addition, pump efficiency can be adversely affected if proper attention is not given to site location.

BLOW OUT AIR LINE FOR 10 TO 20 SECONDS BEFORE ATTACHING TO PUMP TO MAKE SURE ALL PIPE LINE DEBRIS IS CLEAR. The Pro-Flo™ pump is not submersible.

WILDEN PUMP & ENGINEERING CO.

SUGGESTED INSTALLATION

AIR-OPERATED PUMPS: To stop the pump from operating in an emergency situation, simply close the “shut-off” valve (user supplied) installed in the air supply line. A properly functioning valve will stop the air supply to the pump, therefore stopping output. This “shut-off” valve should be located far enough away from the pumping equipment such that it can be reached safely in an emergency situation. NOTE: In the event of a power failure, the shutoff valve should be closed, if the restarting of the pump is not desirable once power is regained.

SECTION 7B

SUGGESTED OPERATION AND MAINTENANCE INSTRUCTIONS For best results, the pumps should use an air filter and regulator. The use of an air filter before the pump will insure that the majority of any pipeline contaminants will be eliminated. The P.025 is permanently lubricated, and does not require in-line lubrication. Additional lubrication will not damage the pump, however if the pump is heavily lubricated by an external source, the pump’s internal lubrication may be washed away. If the pump is then moved to a non-lubricated location, it may need to be disassembled and re-lubricated as described in the ASSEMBLY/DISASSEMBLY INSTRUCTIONS.

When the pump discharge pressure equals or exceeds the air supply pressure, the pump will stop; no bypass or pressure relief valve is needed, and pump damage will not occur. When operation is controlled by a solenoid valve in the air line, twoway or three-way valves may be used. Pumping volume can be set by counting the number of strokes per minute. INSPECTIONS: Periodic inspections have been found to offer the best means for preventing unscheduled pump downtime. Personnel familiar with the pump’s construction and service should be informed of any abnormalities that are detected during operation.

Pump discharge rate can be controlled by limiting the volume and/or pressure of the air supply to the pump (preferred method). A regulator is used to regulate air pressure. A needle valve is used to regulate air volume. Pump discharge rate can also be controlled by throttling the pump discharge by installing a valve in the discharge line of the pump. This is useful when the need exists to control the pump from a remote location.

WILDEN PUMP & ENGINEERING CO.

RECORDS: When service is required, a record should be made of all necessary repairs and replacements. Over a period of time, such records can become a valuable tool for predicting and preventing future maintenance problems and unscheduled downtime. In addition, accurate records make it possible to identify pumps that are poorly suited to their applications.

SECTION 7C

TROUBLESHOOTING Pump air valve freezes. 1. Check for excessive moisture in compressed air. Either install a dryer or hot air generator for compressed air. Alternatively, a coalescing filter may be used to remove the water from the compressed air in some applications.

Pump will not run or runs slowly. 1. Ensure that the air inlet pressure is at least 5 psig above startup pressure and that the differential pressure (the difference between inlet and discharge pressures) is not less than 10 psig. 2. Check air inlet filter for debris (see recommended installation). 3. Check for extreme air leakage which would indicate worn out seals/bores. 4. Disassemble pump and check for obstructions in the air passageways or objects which would obstruct the movement of internal parts. 5. Check for sticking ball check valves. If material being pumped is not compatible with pump elastomers, swelling may occur. Replace ball check valves and seals with proper elastomers. Also, as the check valve balls wear out, they become smaller and can become stuck in the seats. In this case, replace balls and seats.

Air bubbles in pump discharge. 1. Check for ruptured diaphragm. 2. Check tightness of outer pistons. 3. Check tightness of clamp bands and integrity of O-rings and seals, especially at intake manifold. 4. Ensure pipe connections are airtight. Product comes out air exhaust. 1. Check for diaphragm rupture. 2. Check tightness of pistons to shaft. Pump rattles. 1. Create false discharge head or suction lift.

Pump runs but little or no product flows. 1. Check for pump cavitation; slow pump speed down to match thickness of material being pumped. 2. Verify that vacuum required to lift liquid is not greater than the vapor pressure of the material being pumped (cavitation). 3. Check for sticking ball check valves. If material being pumped is not compatible with pump elastomers, swelling may occur. Replace ball check valves and seals with proper elastomers. Also, as the check valve balls wear out, they become smaller and can become stuck in the seats. In this case, replace balls and seats. 4. Ensure that all suction connections are tight, especially lower valve ball retainers.

MODEL P.025 PLASTIC DIRECTIONS FOR DISASSEMBLY/REASSEMBLY CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump should be disconnected and all air pressure allowed to bleed from pump. Disconnect all intake, discharge, and air lines. Drain the pump by turning it upside down and allowing any fluid to flow into a suitable container. Wetted flushing of parts may be required prior to handling. The Wilden model P.025 (Figure 1) is an air-operated, doublediaphragm pump with all wetted parts of polypropylene, Carbon-filled Acetal, or PVDF. The single-piece center section, consisting of center block and air chambers, is molded from Acetal or polypropylene. All fasteners and hardware are stainless steel. The air valve is manufactured of Acetal or polypropylene. All O-rings used in the pump are of special materials and should only be replaced with factory-supplied parts. To expedite parts ordering, please find an exploded view of the P.025 model at the back of this manual. PLEASE read all directions before starting disassembly.

General practices Cable connection and grounding notices Danger! It is NOT allowed to connect pipes etc. to the electric motor terminal box as feed through the power cables! Cables must be fed into the electric motor terminal box using cable glands only! Danger! For a safe ground connection use a cable with a core diameter of at least 50% of the core diameter of the power cables! Caution! To facilitate maintenance operations use cables of sufficient length! Caution! Secure the cables properly to prevent shaving of the cables! Cable connection example

Note: For specific electric motor details review the supplied operating, maintenance and / or repair manuals of the electric motor manufacturer.

0402v0_3.fm Project: 18070051

Section 5 4-1

General practices

4.1.2

Cable finishing standard practices Electric motor power cables are connected between converter (cabinet side) and electric motor. It is very important to connect these cables properly to prevent / minimize Electro Magnetic Interference (EMI) and safety.

The following instruction illustrates how electric motor power cables are connected: Motor side 1. Remove outer insulation. Do not damage cable shielding.

2. Cut cable shielding to approximately 15 cm. Remove foil if there is any.

3. The cable should now look like this.

Section 5 4-2

0402v0_3.fm Project: 18070051

Electric motor General practices The motor side of the cable is fed into the motor connection box using Ex cable glands. An Ex cable gland consist of the following parts. (all parts have their own purpose and therefore all need to be used):

1 - teflon washer 2 - body 3 - inner seal 4 - inner armour clamping ring 5 - outer armour clamping ring

6 - middle body 7 - outer seal 8 - washer 9 - gland nut.

4. Slide parts 5 through 9 over the cable shield. Slide parts 3 and 4 over the cable wires and screw parts 1 and 2 into the motor connection box. Before tightening the gland assembly should look like the picture below.

5. Clamp the cable shield between part 4 and 5 and cut it to length.

6. Now tighten the shield by screwing part 6 firmly in.

0402v0_3.fm Project: 18070051

Section 5 4-3

General practices 7. Slide parts 7 through 9 to part 6 and tighten by screwing part 9. Please make sure to tighten the 3 (brass) body parts separately. If not tightened separately the cable shield could be damaged.

8. After connection of the power cables a motor connection box could look like the picture below. Make sure the power cables do not contact the metal of the box when closed. Connect no more than 2 lugs with one bolt an no more than 1 wire per cable-lug. How to install cable-lugs see the steps further in the text.

Section 5 4-4

0402v0_3.fm Project: 18070051

Electric motor General practices Cabinet side 1. Remove outer insulation. Do not damage cable shielding.

2. Cut cable shielding to approximately 15 cm. Remove foil if there is any.

3. The cable should now look like this

4. Fix shield in place using tape or, even better, using shrink-tube

5. A well prepared cable looks like this

0402v0_3.fm Project: 18070051

Section 5 4-5

General practices 6. This is an example of how NOT to prepare the cable. This is a so called “pig-tail”. A “pig-tail” is the most occurring cause of EMI problems.

7. Now attach the cable to the EMC rail. This rail is located at the underside of the cabinet and can slide to a location above the cable entry. The arrows indicate 2 possible connection methods.

8. Attach the cable to the EMC rail and make sure the shielding touches the rail.

Attach by using (metal) ty-wraps (method 1), or better, by using C-clamps (method 2).

Section 5 4-6

0402v0_3.fm Project: 18070051

Electric motor General practices Cable lug installation 1. After mounting the cable in the connection box or cabinet cut wires to desired length. Remove insulation of wires and make sure to remove protecting foil if there is any.

2. Connect wires trough cable lugs. Use cable lugs with correct diameter (e.g. 70mm2, 90mm2) and bolt hole (e.g. M10, M12). Connect only one wire per cable lug.

3. Use correct crimping tools for mounting cable lugs. This because cable lugs need to be firmly pressed on the wires.

4. Use of a pipe wrench is NOT allowed for crimping cable lugs.

5. Isolate cable lugs using isolating tape, or even better using shrink-tube. The cable is now ready for connecting. Connect phase wires to desired contactor or output reactor. Connect PE wires to PE bar. Connect no more than 2 lugs with one bolt.

0402v0_3.fm Project: 18070051

Section 5 4-7

General practices Profibus cable 1. Measure length of outer isolation to be stripped.

2. Clamp tool to cable and rotate.

3. Pull outer isolation off cable. Cut the outer isolation and shield to length.

4. Remove plastic foil.

5. When connecting make sure shielding touches shield clamp inside connector.

Some connectors need removal of wire isolation, some don’t. Please pay attention.

Original spare parts are to be used for the approved repairs or repairs not falling under the warranty. Live and rotating parts of electrical motors can cause major or deadly injuries. Any shipping, installation, start-up and maintenance works are to be carried out only by qualified personnel (follow carefully any regulations on explosion protection such as EN 60079-14 and SeitenEN 50821-1-2 as well as any other national accident prevention regulations). As regards any equipment subject to these guidelines, it is important to adopt the necessary safety precautions to protect the personnel against possible injuries.

The personnel must be duly instructed to proceed with caution and according to regulations during shipping, hoisting, and positioning and while repairing the motor. Do not lift the motor together with the drive equipment by the motor lifting eyebolts. Do not use the supplied lifting eye bolts at ambient temperatures below –20°C, in accordance with DIN 580. Lower temperatures could lead to the ring screws breaking and consequent breaking and consequent injury to personnel and/ or damage to the installation. Do not load the eyebolts as per DIN 580 no more than 45° compared to the screwing direction. The use of crossbeams is recommended. See the operating instructions for the layout dimensions of the lifting eyebolts and the minimum dimensions of the loading crossbeams and chain lengths. In the case of motors with built-in brake appropriate safety measures are to be adopted against the possible failure of the brake especially in applications involving the pulling of loads. Operating the motor with the supplied shaft protection cover alone is forbidden. Contact with the capacitor for the startup and running of single-phase motors is to be avoided until the unloading procedure is carried out securely. If a high-voltage test is necessary, the procedures and precautionary measures set forth in accident prevention regulations are to be followed.

Spare parts When ordering spare parts, besides the name of the required part, specify also the motor type and serial number.

Delivery, Storage, Transport Delivery

Check the motor for damages during transportation.

In case of damage during transportation an investigation of fault is to be performed by the forwarding agent.

Report any covert damages to the forwarding agent or manufacturer no later than seven days from the transfer of the motor.

The entire packaging material can be recycled by means of the Dual System.

Storage Storage up to a maximum of 36 months is possible in the following conditions: • In order to prevent a drop in the insulation resistance, the surrounding environment must be dry and dust-free. • The room temperatures should not drop below +5 °C or exceed +30 °C with an air humidity of < 70 % and register changes in temperature greater than 10 °C/day. • In order to prevent damage during storage any occurring oscillations must amount to Veff < 0.2 mm/s. • For motors with regreasing systems repress an amount of grease double that specified on the motor at standstill before storage. Please note! In case of storage conditions deviating from those specified above the measures set forth in the separate AR9 storage instructions must be adopted.

Transport Do not lift the motor together with mounted driven machines such as, for instance, pumps, gearing, etc. by the motor lifting eyebolts. Do not use eyebolts as per DIN 580 at ambient temperatures lower than – 20 °C. At these temperatures the eyebolts may break and hence injure the personnel and/or damage the machinery. Do not load the eyebolts as per DIN 580 no more than 45° compared to the screwing direction. The use of crossbeams is recommended. Layout dimensions of the lifting eyebolts and the minimum dimensions of the loading crossbeams and chain lengths. (Î Fig. 1). Please note! When mounting vertical motors from the horizontal position, the shaft must not touch the floor to avoid damaging the bearings.

Installation

Mechanical checks After removing the shipping braces and shaft blocks (see also the marking on the motor), the motor shaft must be rotated by hand. In the case of brakemotors the brake must be vented at standstill (maximum of 10 min). This must be performed after applying voltage as per the circuit diagram from page 39. Please note! Save the shipping braces and shaft blocks for subsequent transportation, as the bearings risk being damaged during transportation. Site The completely closed motors are intended for operating sites in which they are exposed to soiling, humidity and other open air conditions as per the relevant degree of protection. The motors must be installed in a place with ambient temperatures of –20 °C to a maximum of +40 °C and a max. of 1000m above sea level. Any permissible ambient temperatures (Ta) and heights (MSL) other than those indicated above must be specified on the rating plate. Lower temperatures and values not found on the rating plate require the use of space heaters. Î Section 3 “Operation and Repairs” Please note! The ventilator hood air inlet and outlet must not be obstructed, as there is the risk of heating beyond the permissible temperature class and of reducing the life of the winding insulation Î Fig. 2 and Î Table 2. This applies in particular to the use of soundproof covers. The air ducts must checked and cleaned regularly in factories with heavy soiling.

The motors are intended for use in areas subject to explosion hazards. The following data on the rating plate distinguish the motor as explosionprotected equipment: • Degree of protection • Explosion group • Temperature class Depending on the appliance category the motor is assigned to the relevant zone of the operating site.

Mounting The motors are mounted either on the motor feet or on the flange at the installation site. All motors with shaft heights of up to 355 mm can be mounted either horizontally or vertically thanks to their bearing layout. This applies also for motors to be mounted with the feet on roofs and side walls. Motors with reinforced bearings are to be operated at a minimum load to ensure the smooth operating of the anti-friction bearings (Î Table 3).

The bearings may be damaged if the minimum load is exceeded. Trial runs with no-load should last only a few minutes. You can find the max. permissible loads in our catalogue "ExplosionProtected High and Low Voltage AC Motors" or contact the manufacturer. Align the motors according to the requirements of the coupling or pulley manufacturer. The feet are to be positioned evenly and, if necessary, lined. Please note! Make sure that the fastening screws are duly dimensioned.

Data on the foundation loading generated by the motor can be requested from the manufacturer by specifying the motor number. The fastening screws must be duly tightened according to their layout and secured to prevent loosening during operation and hence the damaging of the drive. (Î Table 4, page 17).

Figure 3: Motor Fastening c Large-surface Washer

In order to achieve an adequately large contact surface, apply a largesurface washer under each nut or screw head (Fig. 3).

Alternatively use flange nuts or bolts.

If the motors shaft end points up or down (vertical mounting arrangement), it is necessary to fit an appropriate cover to prevent any foreign bodies from dropping in the driven machine through the air inlet and outlet openings in the ventilator hood. Please note! The flow of cooling air through the motor must not be limited by said cover (Î Section "Site", page 10).

The balance of the motors is specified on the shaft end plate and/or on the rating plate (H = half key, F = full key, N = no key). The design of the coupling or pulley must match the motor's balance.

Please note! If balancing with half key (H), work on the vertical (visible) key components on the shaft diameter or cover these with washers with keyway along the relevant length. If the coupling is longer than the key, it is necessary to fill the keyway in the remaining part of the coupling. In case of failure to comply with the foregoing, out-of-balances liable of causing excessive vibrations may occur.

Please note! Mount the pulleys or couplings only through the threaded bores in the shaft end to avoid damaging the anti-friction bearings (Î Fig. 4).

Fig. 4: Fastening of the pulley or coupling

Screw the threaded bolts in the threaded bore.

Then mount the pulley or coupling on the shaft end: make sure to screw a nut with a washer having at least the same diameter of the pulley hub or coupling on the threaded bolt.

Use the utmost care in mounting dynamically balanced pulleys or couplings on the shaft end. Machines to be connected to the motor by means of couplings are to be aligned according to the specifications of the coupling's manufacturer.

Only use flexible couplings!

Mains and other electrical connections The motors work as per VDE 0530 with mains voltage oscillations of up to ±10 % or frequency oscillations of up to –5 % to +3 %. The mains ratings must match the voltage and frequency data specified on the ratings plate. Connect the motors according to the connection diagrams attached to the terminal box (Î Figure 11 page 34). Use only the supplied original connection components, (Î Section " Mains and guard circuit connection", page 21). Please note! Carry out the motor, controller, overload protection and earthing connection operations in compliance with local installation requirements.

Please note! If the accidental starting of the system may expose the personnel to danger, do not use any automatically restarting motor protective equipment.

Mains connection of explosion-protected motors Besides any general installation regulations, follow carefully EN 60079-14 and EN 50281-1-2. Afterwards suitable overload protection is to be provided either with a motor circuit breaker or similar protective devices. These may include also PTC thermistors with tripping devices (Î Section "Motors with temperature monitoring“, page 25). These must be specified on the rating plate together with a tripping time tA. In addition, any "Special Requirements" specified in the test certificate are to be complied with. These are marked with an "X" after the test certificate number on the rating plate. Motors with direct line lead-in The free end of the cable inserted in the motor must be connected according to the regulations in force concerning the connection area. If the line lead-in used on the motor is provided with pull relief, the cable can be laid freely; otherwise the cable must be secured with a pull relief device in the near vicinity. The maximum operating temperature at the line lead-in must not exceed 90° C. Terminal box Open the box by loosening the screws on the cover (Fig. 5) or, in the case of models with grub screw (Fig. 6), by turning the grub screw counter-clockwise and then loosening the tapped cover. Close the terminal box again after connecting the mains by following the same instructions in the opposite order. In order to change the position of the cable and line lead-ins, you can turn the terminal box by 4 x 90°.

Loosen either – the four fastening screws (ÎFig. 5 ) or – the anti-rotation pins by means of the grub screw (Î Fig. 6 ).

Turn the terminal box to the desired position.

Please note! Terminal boxes fastened as per Fig. 6 are to be turned counter-clockwise by a maximum of one turn away from the thread end stop. Screwed-on covers must be duly secured.

Anti-corrosion protection can be achieved with non-hardening sealing materials or sealing grease in particular on the processed sealing surfaces of the covers of terminal boxes having the following degree of protection: "pressure-resistant encapsulation, EEx d IIC(B) marking".

The approved sealing materials are: • For threads and surfaces: Hylomar, by Marston-Domsel or • for surfaces: Admosit and Fluid-D, by Teroson. Please note! In the case of "increased safety" terminal boxes the gaskets used are included in the approval. Only original gaskets are to be used.

Please note! "Pressure-resistant encapsulation“ terminal boxes must be sealed by means of approved cable or line lead-ins.

Cable and line lead-ins Connect the motors with cable and line lead-ins or by means of a duct system as per EN 60079-14. These must meet the following requirements: • EN 50019 for wiring spaces with a degree of protection of "increased safety", (EEx e II marking on the component) • EN 50018 for a degree of protection of "pressure-resistant encapsulation”, (component EEx d IIC(B) marking on the component) Specific test certificates must be provided for cable and line lead-ins. Please note! In case of motors complying with the new Directive 94/9/EC, (e.g. marking II 2G ...), these must be mounted only with the supplied original lead-ins or lead-ins that meet the requirements of the new directive.

Any openings that are not used must be closed with sealing plugs for which the relevant test certificates and/or the aforementioned markings must be provided. The supplied sealing plugs for the line lead-ins serve only as protection during transportation and are not an approved sealing means. This applies also for the storage of motors outdoors. In this case additional rain protection is required. The lead-ins supplied as a standard (version 1) are used for the insertion of firmly secured lines. Version 3 available as a special accessory, with additional pull relief, is used for the insertion of lines in movable motors. Please note! Cable lead-ins and sealing plugs that fail to meet these requirements are prohibited. The cable and line diameters used must comply with the clamping range specified on the lead-in. Follow carefully the operating instructions of the cable and line lead-ins.

Motors with terminal boxes whose mains lead is located in the layer separating the upper and lower parts Use only the supplied original gaskets to ensure compliance with the “Ex e II” degree of protection. Depending on the type (see marking on the plug), the plugs are fit for the following diameters (ÎTable 5). Follow carefully the operating instructions for the lead-in parts and sealing plugs. Table 5: Type

Cable diameter Cable diameter

After connecting the mains lead close the terminal box with the upper part. Strip the skins of the plugs so that the following condition is fulfilled: By stripping the skin, the plugs are adapted to the cable diameter so that a gap of less than 1 mm is obtained between the cable and the plug applied on the cable. Therefore, an extra layer of skin must be removed from one half of the module compared to other. Lubricate the cutting edge and the sealing surfaces of the plug with the supplied grease. Insert the plug halves over the cable and completely in the bushing opening. Brace it with the screws until a perceivable resistance (maximum torque: 6 Nm) is achieved.

Depending on the model, additional terminals for instance for temperature monitoring or space heater are located either in the main terminal box or in additional terminal boxes; see the supplied wiring diagram. Please note! Take note of the rating data imprinted on the terminals.

Please note! Keep the wiring diagram supplied in the terminal box in the enclosure with the documents belonging to the drive.

Motors with unidirectional fan Make sure that the fan's direction of rotation matches that of the motor.

Motors with separate cooling via separately powered external fans Make sure by means of the electric control that the main motor can be operated with the motor switched-on for separate cooling.

Motors with temperature monitoring Terminals 1TP1-1TP2 or 2TP1-2TP2 The motors are equipped with PTC's as per DIN 44081. Take note of the temperature data and tripping time tA on the rating plate. Connect the PTC to an approved tripping device with marking PTB 3.53PTC/A or II(2) G.

Please note! The tripping device is not explosion-protected. For this reason install them outside the areas subject to explosion hazards.

The marking confirms whether the electrical data on the interface between the temperature sensor circuit and the tripping device have been fulfilled. The use of the tripping device with PTC temperature sensors as per DIN 44081 is allowed for the thermal monitoring of explosion-protected electrical machinery. Being the only overload protection as set forth in EN 60079-14, the temperature sensors herein described can be used together with an approved tripping device only if the tripping time tA is specified on the motor rating plate. (Refer to Section 3, Operation & Repairs, page 42)

Motors with space heater Terminals HE1-HE2 or U1-V1 The rating data for the space heater are specified either on the rating plate or on a separate plate. Depending on the model, there are two heating variants: • by means of heater bands powered via terminals HE1-HE2 or • by means of the stator winding by feeding AC voltage to terminals U1V1. Please note! Make sure by means of the electric control that the motor voltage and the heater voltage are not fed simultaneously. Please note! The heater is not explosion-protected. It must not be switched on at motor temperatures below -20°C to heat the motor to at least –20°C. On the contrary, its purpose is that of preventing that the motor temperature falls below –20°C when idle.

Motors for operating on frequency converters For operating on frequency converters, motors with temperature monitoring must be protected by PTC temperature sensors (Î Section "Motors with temperature monitoring", page 25). The rating data for this operating mode are specified either on the rating plate or on a separate plate. If the relevant plate is missing, see the data provided in the manufacturer catalogue "Explosion-protected high and low voltage AC motors in II 2 G/D EEx d(e) IIC(B) T4...T6“ (Î Torque curves see diagram 1 to 6, page 28+29). Check the drive's "electromagnetic compatibility" as per EMC directive no. 89/336/EEC when operating on frequency converters. Make sure when operating motors on frequency converters that the admissible voltage peak value named below are not exceeded by the

periodically occurring commutation voltage peaks (threshold value for terminals and winding insulation): 1. Terminals have effective clearance and creepage distances to withstand a voltage of 750V based on DIN EN50019 - increased safety type "e". The maximum transient over voltage from the frequency inverter to the motor is 2.15 kV (phase to phase and phase to earth). 2. Standing winding for 230/400V and 500V can withstand a peak voltage of 1.6 kV (phase to phase and phase to earth) with winding temperature rise corresponding to class F, our standard windings can be used with frequency inverters without the need for additional filter. 3. Standing winding for 400/690V can withstand a peak voltage of 1.6 kV (phase to phase and phase to earth) with winding temperature rise corresponding to class F, our standard windings can be used with frequency inverters with additional filter. 4. Special winding for a single nominal voltage of 690V can withstand a peak voltage of 2.15 kV (phase to phase and phase to earth) with winding temperature rise corresponding to class F, this windings can be used with frequency inverters without the need for additional filter. These motors will be marked with an “U” in the type code on the rating plate. In the case of a converter output non-galvanically separated from the mains and with current limitation, follow the requirements of DIN EN 50178 and VDE 0160 (equipment of high voltage installations with electronic devices) on the overload protection of the protective earth conductor. In rating the protective device in the outer conductors, bear in mind that the protective earth conductor current can be greater than the outer conductor current in fault condition. The protective earth conductor is to be dimensioned according to this fault current. Take note of all of the data of the converter manufacturer for said fault condition.

Motors with built-in frequency converter (compact drive) Please note! Wait at least 3 min. after disconnecting the drive from the mains before connecting it again; otherwise there is the risk of damaging the input current limitation.

Warning! After disconnecting the drive from the mains, the conductive parts of the frequency converter and the connected conductor may still be live for up to 180 sec. Wait at least 3 min. after disconnecting before opening the casing or touching the drain screw. Follow the operating instructions or the instructions provided in the converter's manual as well as the relevant safety regulations. In some models an automatic restarting of the drive takes place after a power failure.

Parameter setting The parameters of the incorporated converter were set by the manufacturer for the relevant application. This setting does not correspond to the original factory setting made by the converter manufacturer. A list of parameters is found in the attached converter manual. Changing specific parameters can cause a drive operation in a critical area. This may lead to a fault trip of the converter or the tripping of the PTC temperature monitoring. A change in the motor voltage and clock frequency parameters is prohibited. The motors can be operated in a frequency range of 2 Hz (limited torque) to 100 Hz. The converter's clock frequency amounts to 4 kHz.

The parameters can be changed with the keypad according to the instructions provided in the converter manual. Insert the keypad plug in the test socket of terminals 5-6-15-16. The keypad is not approved for use in the area subject to explosion risk. Operating on unearthed network (IT) Motors with an incorporated CEIGL ... IT type frequency converter can be operated on the IT network. In case of a short circuit in the drive the tripping must take place as quickly as possible. Explosion protection The explosion protection is ensured in all conditions, since the motor and converter are to be monitored by the PTC temperature sensors (ÎSection "Motors for operating on frequency converters" , page 26). In the case of motors with incorporated frequency converter equipped with a PTC tripping device and relay, said protection is provided for without external tripping. All the screws are to be tightened to the envisaged torque (Î Table 4, page 17) and just as many screws as necessary for the envisaged fastening boreholes are provided. Any damaged screws are to be replaced only with screws of the same dimensions and quality (at least 8.8).

Relay and PTC tripping device Motors with incorporated frequency converters can be equipped either with a relay or a PTC tripping device to ensure protection against overheating as required by IEC 60079-14. The PTC tripping device is accessible by means of a hexagon locking screw (SW 67) on the upper face of the pressureresistant casing. The locking screw must be completely screwed in during operation and is to be secured with anaerobic adhesive for screws.

In case of a device with shared power and control voltage supply (Î Fig. 12) no automatic restarting of the drive takes place after a power failure or the tripping of the protective device. Caution! In case of a device with a separate control voltage supply (ÎFig. 13) an automatic restart of the drive takes place after a failure in the power supply. After a power failure in the control voltage supply there is no automatic restart of the drive. A failure in the control voltage triggers the reset of the PTC tripping device.

Warning! The compact drive feeds voltage also when the device is off. Before performing work on the device or external control unit, disconnect the mains line.

Motors with brake The mains line in the version with incorporated brake is connected in the motor terminal box and in the version with the built-on brake in the separate brake terminal box. Observe the supplied connection diagram and the rated voltage visible on the rating plate. In the presence of an AC connection the brake coil is energized by means of a silicon rectifier accommodated inside the explosion-proof encapsulation.

The temperature sensors applied both in the motor and brake are to be connected as envisaged in Section "Motors with temperature monitoring", page 25.

Motors with brake or tachometer mounted under the ventilator hood In order to connect brakes or tachometers mounted under the motor ventilator hood, the latter must be disassembled. Unscrew any shock pulse sensors or regreasing devices. Loosen the fastening screws on the hood and remove the hood from the motor. Connect the brake of tachometer as per the attached circuit diagram and pass the cable along the shortest route through the motor fins towards the main terminal box. It is recommended to insert a protective tube over the connection cable in the fin area to prevent wearing. Fit the ventilator hood back on the motor and check the position of the boreholes for any shock pulse sensors and regreasing devices. In the case of motors with an axial fan running into a nozzle, make sure that there is a uniform air gap all around between the fan and nozzle. Secure the hood with the fastening hoods, (torque as per Table 4, page 17) Check manually that the fan runs freely once the mounting is completely.

Motors with water cooling Before connecting, check the cleanness of the cooling water (max. permissible content of deposits: 30 mg/l). The water connections are to be connected according to the signs on the motor. The quantity of cooling water necessary for cooling the motor is to be complied with (see the sign on the water inlet). To eliminate any entrapped air, the motor's counter-drive side is provided with a bleed valve. The cooling water quantity control must shut off the motor if there is less cooling water than required. The water chambers must be cleaned regularly depending on the content of deposits. They can be cleaned without disassembling the motor. After unscrewing the sealing ring on the motor casing's counter-drive side, it is possible to clean the casing. The explosion protection is not affected by unscrewing the sealing ring, as the water chamber is not located in the pressure-resistant section. Make sure by means of the electric control that the motor can be operated only with the water flow on and that the water jacket is always perfectly vented. The maximum inflowing water temperature amounts to 30 °C.

Operation and Repairs

Duty types and thermal protection • In S1 duty class motors a temperature sensor (TS) can be used in addition to the motor circuit breaker as required by DIN EN 60079-14, VDE 0165. • If in S1 duty cycle motors protection is to be provided against overheating only by means of the TS, a proven combination of TS and tripping device is to be used for said purpose. • In the case of non-S1 duty cycle motors proven combinations of TS and tripping device must be used as protection against overheating. • The supplying of power to the motors via the frequency converter is permissible only if a proven combination of TS on the windings and tripping device is used. The temperature sensors must be connected as specified in the Section "Motors with temperature monitoring", page 25.

Special operating conditions The operating of the motors at ambient temperatures outside the generally valid range of –20 to +40 °C is allowed also without heater if an appropriate temperature range – e.g. –55 °C Tamb 60 °C – is specified on the rating plate. Operation at less than –20°C is allowed also without any additional indication if the temperature of the entire motor is maintained at least at -20 °C by means of a space heater. At motor temperatures of less than -20°C the heater must not be started, as these are not explosion-protected. (Î Section "Motors with space heater", page 26).

Motors with backstop Motors with built-in backstop must be operated at a minimum rpm higher than the value specified on the rating plate – e.g. FXM 850 min –1 – to prevent excessively high temperatures.

Heat input through the driven machine It must be ensured that no quantities of heat greater than the maximum heating values specified in table are conveyed from a mounted machine to the interface with the motor (e.g. shaft and motor flange). This way it is guaranteed that no point of the motor exceeds the temperature class. Table 9: Permissible surface heating at an ambient temperature of 40°C:

Permissible heating on the shaft Permissible heating on the flange

Temperature class T6 = 85°C T5 = 100°C T4 =135°C 30K 45K 65K 30K 45K 65K

Start-up Please note! Before mounting or start-up the insulation resistance is to be measured by qualified technicians. The resistance must be greater than 1 Mȍ. A critical value is reached at 0.5 Mȍ. If this value is not reached, the motors must be dried.

The best way to do it is in an oven at temperatures up to 100 °C. To eliminate any humidity, open the motor. To be entitled to any warranty claims, contact the manufacturer in advance. These works must be carried out by qualified technicians; in the course of said works the manufacturer shall instruct said technicians on how to ensure the explosion protection during reassembly. For the assembly and disassembly, see the relevant repair instructions.

• Check the direction of rotation and operation during idle running. In case of unidirectional external fans (axial fans) observe the sign for the direction of rotation on the motor. If the direction of rotation needs to be changed, invert the two power lines and the fan. • If the motor was stored and an additional quantity of grease was applied in the anti-friction bearings, the motor must be run with no load for at least 0.5 h to ensure an adequate distribution of the grease and to avoid the overheating of the anti-friction bearings. • Make sure that the operating current matches the specified current values on the rating plate. The protective equipment required as per EN 60079-14 is to be set according to the motor rating values specified on the rating plate. The specified current value on the rating plate must not be exceeded in continuous duty conditions. Please note! Run the motor with load for at least 1 hour and check that there is no unusual noise or heating exceeding the specified temperature class values.

Relubricate motors with regreasing equipment with the specified amount of grease during start-up. Vibration severity values of Veff 3.5 mm/s (PN 15 kW) or 4.5 mm/s (PN > 15 kW) in coupled operating mode are not allowed. In case of deviations from normal operating conditions – e.g. higher temperatures or greater noise and vibrations – find the cause and, if necessary, contact Producent. Please note! The protective equipment must always be kept in service also during trial runs. In case of doubt switch off the machine.

Maintenance Inspection • The motors are to be constantly monitored depending on the operating conditions. • Keep the motors clean and the venting openings free (Î Section "Site", page 10) Any national regulations valid for the maintenance/repair of electrical equipment in areas subject to explosion hazards - e.g. in Germany the Operational Safety Order, etc - are to be complied with. During maintenance especially those parts on which the degree of protection depends must be checked; these include, for instance, the integrity of the lead-in components and gaskets.

Lubrication Please note! In order to avoid damage the bearings and grease must be kept clean.

The deep groove ball bearings of motors up to frame size 280 are sealed on both sides and filled by the bearing manufacturer with a grease which is enough for normal operating conditions in 4 or multi-pole motors for 40000 operating hours or in 2-pole motors for 20000 operating hours. When changing the bearings, change also the shaft seals. To do so, dismount the motor so that the winding can be cleaned at the same time. Disassembly and assembly as per the specific manufacturer repair instructions. Motors starting from frame size 315 and motors with reinforced bearings are to be equipped with regreasing devices. The bearings are to be regreased preferably with the motor running with a grease gun through the grease nipples located over the bearing plates or bearing caps.

The drip space in the bearing cap for outflowing old grease is large enough to collect the outflowing grease during the nominal bearing service life with state-of-the art regreasing. See the plate on the motor for the specified lubricating intervals and the type and quantity of grease to be used. The manufacturer normally uses ESSO Unirex N3, a lithium complex soap/mineral oil grease. Table 10: Ambient temperature

Standard regreasing intervals in hours Rpm up Rpm up to 1800 min–1 to 3600 min–1

40 °C 50 °C

5000 h 2500 h

2500 h 1000 h

Please note! In motors with enhanced performance (motor type ...X), in heavy drive conditions like belt and gear drive with additional bearing loads and in vertical designs the lubricating intervals are to be reduced by 50%. Observe the specified quantity of grease. Overgreasing can lead to a sharp increase in the bearing temperature and hence to the failure of the bearing.

Caution! If regreasing is carried out while the motor is running, provide for adequate protection against rotating parts! Only resin-free and acid-free anti-friction bearing grease with a drop point of approx. 200°C is to be used.

Explosion protection (II2G), EEx de IIC T4, for instance, indicates where the motor The marking is to be used and that it has been designed, built and approved according to the relevant European standards required for operation in areas subject to explosion hazards. Please note! The motor must not be altered in any way whatsoever and the operating instructions set forth herein are to be complied with always.

If the motor is altered or repairs need to be made, these are to be performed by the manufacturer or by repair workshops or factories that possess the necessary know-how. Before the starting the motors again, conformity with the requirements of EC directives 76/117/EEC or 94/9/EC and 99/92/EC by said sites is to be ascertained and confirmed by means of an appropriate marking on the motor or by issuing a test report. If these requirements are not met, the motor is no longer classified as explosion-protected and the marking - see above - is to be removed. Instructions for ensuring explosion protection during operation • All of the contact screws and nuts of the electrical connections are to be tightened securely to prevent excessively high contact resistance values that may lead to an excessive degree of overheating of the contact point; torque values (Î Table 8, page 24). • Use the utmost caution when connecting the mains cable. Observe the creep distances and clearances. Use duly the sealing parts of the cable lead-ins and connections spaces as well as the lead-in parts envisaged for the pull relief or as protection against torsion in order to maintain the degree of protection of the connection spaces (Î Section "Mains and guard circuit connection ", page 21). • Eliminate any damages immediately and use only original spare parts. The proper performance of the works by the aforementioned sites is to be examined as per the relevant EC directives, in Germany by a qualified expert as per “Betriebssicherheitsverordnung”, abroad as per the relevant national regulations in force and to be confirmed by means of an appropriate marking

on the motor or by issuing a test report. • The surfaces of ignition-protected gaps must not be reworked. Keep these surfaces metallically clean. Corrosion protection can be achieved by means of non-hardening sealing materials or sealing grease. The approved sealing materials include besides the corrosion protection greases available on the market: Hylomar, by Marston-Domsel or Admosit and Fluid-D, by Teroson (follow the manufacturer's usage instructions). This must be observed in particular for the openings in the cover for connection spaces having a pressure-resistant encapsulation degree of protection, marking EEx d IIC(B). • All the screws are to be tightened to the envisaged torque (ÎTable 4, page 17) and just as many screws as necessary for the envisaged fastening boreholes are provided. Any damaged screws are to be replaced only with screws of the same dimensions and quality (at least A2-70).

Repairs Repairs and changes to explosion-protected machines are to be carried out by one of the aforementioned sites as per EC directives 94/9/EC and 99/92/EC, in Germany in compliance with the “Betriebssicherheitsverordnung” as well as with the safety regulations and requirements of the repair instructions. Any works relating to the explosion protection must be carried out by the manufacturer or by a specialized workshop for electrical machinery. If said works are not performed by the manufacturer, these must be surveyed by an authorized qualified person. In Germany a written certificate as per the Operational Safety Order is required for restarting. In foreign countries the national regulations in force are to be complied with.

Additional dust protection requirements (application in zones 21 and 22)

Intended use A marking of at least IP 65 and rating plate.

II 2D T …° C must be found on the motor's

Installation and Operation Cable and line lead-ins Separately approved lead-ins belonging to category 2G with at least IP 65 or category 2D are to be used. Any openings that are not used are to be closed with duly approved plugs. Operation and Repairs The motors must not be operated with excessive dust deposits, as these may lead to the exceeding of the admissible surface temperature. Regular cleaning must be performed. The radial shaft seal rings are included in the approval. Only original gaskets are to be used.

Explosion-Proof F&G Three-Phase Motors

Warning! Dangerous electrical voltage! Observe explosion protection measures! Before commencing repair work The following safety instructions for the repair of explosion-proof three-phase motors in flameproof enclosures – designation: Ex II 2.EEx d(e) IIC(B) T – must be observed in addition to the general installation instructions and the provisions of the operating manual. The operating manual provides instructions on the installation of the standard motor types and is not a substitute for any specialist training in the sense of the relevant explosion protection standards. • Disconnect the power supply of the device • Ensure that the device cannot be accidentally restarted • Verify isolation from the supply • Earth and short-circuit • Cover or enclose neighbouring units that are live. • Follow the installation instructions of the device concerned. • Only suitably qualified personnel in accordance with EN 50110-1/-2 (VDE 0105 Part 100) may work on this device/system. • The electrical installation must be carried out in accordance with the relevant regulations (e.g. for cable cross-sections, fuses, protective conductor connections).

• Where installations are subject to these guidelines, appropriate safety measures must be taken in order to protect personnel from injury. • Personnel must be instructed in how to proceed with care and observe the regulations in the transport, lifting and installation of the motor, as well as in recommissioning and repair. • Do not use the lifting eye bolts to lift the motor together with the drive device. • Do not use the supplied lifting eye bolts at ambient temperatures below –20 °C, in accordance with DIN 580. Lower temperatures could lead to the ring screws breaking and consequent injury to personnel and/or damage to the installation. • The eye bolts should also not be loaded at an angle of more than 45 ° from the vertical direction and outside the plane of the ring, in accordance with DIN 580. In this case use transverse rods. Dimensions for positioning lifting eyes and minimum dimensions of transverse rods and chain lengths, see our operating manual. • Suitable safety measures should be taken against possible brake failure on motors fitted with an external brake. This particularly applies to brake motors used in lifting applications.

• The opening of the motor without the manufacturer's consent, apart from the opening of terminal boxes, will invalidate the warranty during the warranty period.

• Avoid contact with the start and operation capacitors in singlephase motors until a secure discharge has occurred.

• Original spare parts must be used for approved repairs or repairs outside of the warranty period.

• If high-voltage tests are required, follow the procedures and precautionary measures laid down in the accident prevention regulations.

• Electrically conducting and rotating parts of electric machines may cause serious and/or fatal injury.

1 Explosion Protection

These are the Directive 94/9/EEC; this has been implemented in Germany by the draft for electrical equipment in hazardous areas Elex V, DIN EN 50014, 50018 and 50019 and VDE 0170/0171 etc. This particularly applies when work is carried out on parts on which explosion protection depends. Parts on which explosion protection depends are: • • • • •

Gap connections and shaft bushings, Fastening screws, Seals, Cable glands and entries, Terminal points.

Working on explosion-proof components

Joint connections and shaft bushings Caution! Gap surfaces (joint surfaces of components) must not be machined, coated or painted. Keep the surface metal clean. Surfaces must not have any surface damage (e.g. fractures or grooves).

Fastening screws Damaged screws must be replaced by new parts with the same material quality and must be sufficient for the number of fastening holes provided.

Seals, cable glands, entries and terminal points Damaged parts must be replaced by original parts.

English

Warning! The repair and recommissioning of explosion-proof motors in flameproof enclosures must comply with the relevant legal provisions:

After repair work If a part of a motor has been repaired on which explosion protection depends, the following requirements must be fulfilled for commissioning: An appointed inspector must verify that the essential explosion protection features of the motor meet the requirements of the applicable regulations. This inspector must issue the operator of the motor with appropriate certification of this compliance. The inspector must attach an appropriate approval mark on the motor or by issuing a test report. Warning! All components used on the motor must comply with the protection type of the motor concerned and the relevant standards. This is denoted by designations such as II 2 G EEx d IIC(B) T4, on motor and components. Prior to recommissioning carry out the tests specified in Chapter “Tests”, Page 24.

Corrosion protection can be achieved using non-curing sealant (static gap surfaces) or sealant grease (static or rotating gap surfaces). Permissible sealing materials are Hylomar from Marston-Domsel, or Admosit and Fluid-D from Teroson.
