INTRODUCTION

This manual contains general installation, operating, maintenance and troubleshooting instructions for the Gearbox’s. These gearboxes are rugged, high quality designed in accordance with standards of the American Gear

Manufacturers Association to give many years of trouble-free service. However, optimum performance can be expected only if the procedures in this manual are followed. Should questions arise that are not covered in this guide, additional information may be obtained by contacting Ace World Companies service department.

All inquiries should be accompanied by the following information, which can be obtained from the gearbox nameplate:

Gearbox size and Type

All Orders for renewal parts or replacement parts should include description and part number shown on the parts list supplied in this manual (see section 7).

NOTE

Adequate installation, maintenance, and safety instructions must be given by the User to personnel directly responsible for the operation of the gearbox. In addition, the procedures set forth in the operating instructions must be followed carefully.

HANDLING

When handling the gearbox, care must be taken to avoid supporting or lifting in a manner that would place excess stress on parts that are not designed to support the unit’s weight.

Never drag the gearbox. This will mar the machined mounting surfaces and may overstress housing.

Use only lifts that are adequately maintained and that possesses sufficient load carrying capacity for the particular application. Secure and balance the load properly to prevent shifting during suspension.

Page 1 of 2

When attaching slings to the gearbox, attention must be given to the behavior of the sling under load. Do not attach a sling in a manner which will damage any exterior components mounted on the gearbox.

PROLONGED STORAGE

When gearbox is shipped from factory it is filled to cover all gears to prevent rust from forming. At time of installation oil is drained and refilled to the proper level which is determined by the sight gauge as to when it is to its proper level.

When prolonged storage is necessary it should be in-doors and preferably in a dry free area having a relatively constant temperature.

When outdoor storage is unavoidable, gearbox should be raised off the ground on skids and covered with a tarp or equivalent covering.

GENERAL:

Hoists are tested before being shipped from the factory. To place hoist in service, set on bridge and connect to electrical service.

WARNING

Before attempting installation of hoist/trolley, the main power switch must be locked in the open position.

Perform pre-operation checks and tests before placing in service.

The successful operation of the hoist depends upon a properly installed bridge. The bridge should be checked for adequacy of the following:

Size of trolley rail (trolley wheels are arranged to operate on a specific rail size.

Trolley rails are to be solidly fastened to the supporting girder.

The rails shall be straight, parallel, level and at the same elevation. The distance

(gage) center to center of bridge rails as well as the rail elevation shall be within a tolerance of plus or minus 1/8” (.32cm).

Rail joints must be smooth and held in tight alignment by properly fitted rail joint bars so that ends are held tightly with no crack or opening.

The bridge should be designed in accordance with specifications outlined by the

Crane Manufacturer Association of America for the maximum wheel loads involved.

Size and placement of trolley end stops or bumpers should be checked to insure that they are of the proper height and width to fully contact the trolley wheels and also placed so as to stop the trolley with sufficient clearance between any portion of the trolley and the building.

The trolley is grounded

LUBRICATION:

All hoists are completely lubricated at the factory.

WARNING

Before energizing the hoist, and prior to running any motion, be certain that you have read this manual in its entirety and you are familiar with your hoist.

Check the main switch serving the runway conductors and also the main disconnect switch on the bridge. Lock both switches in the open position (power off).

Check trolley wheels

Check all connections for tightness of bolts, inclusion of lock washers or other type fasteners, to insure correct material as been used. This check must be made for all connections, mechanical, structural and electrical including both field and factory made connections.

Check to insure that all shipping supports, tie downs, brackets or other items which were used only for shipping or storage purposes are removed from the trolley.

Check alignment of trolley collectors

Check electrical wiring fro conformance to the wiring diagram.

Check all gear cases for oil level, and check all other parts for lubrication.

Check to be certain that the trolley and bridge is clear and free of all obstructions.

Prior to the start of these tests, make a last minute check to see that loose parts, such as tools, covers, excess hardware, nuts, bolts, etc., have been picked up and safely stored.

Only qualified personal (electricians, etc,) be used for testing unit.

3 of 6

CAUTION

Verify that the trolley furnished has the same voltage, frequency, and phase as the bridge power supply.

Place all master control switches in the OFF position. If trolley is pendant push button operated, check that all buttons are in the OFF (fully released) position. Open power circuit knife switches of each control panel. If the panels are not so equipped, then remove fuses in the motor circuit.

Hoist Test: a) Test is made prior to reeving the hoist. If your hoist was reeved at the factory then lower the load block manually to a position 8 to 10 feet below the trolley. This can be done by manually releasing the motor brake; some effort will be required to rotate the motor shaft. b) Close the mainline disconnect switch serving the runway conductors. c) Using a voltmeter, check all legs of the power leads at the mainline disconnect switch, located on the crane. Determine that power being supplied is of the correct voltage. d) Close the mainline disconnect switch after checking to see that fuses are is place. e) Energize the mainline contactor by depressing the START button. Deenergize by depressing the STOP button. The action of the contractor in closing and opening the circuit is operating leave circuit with mainline contactor energized. f) At the hoist control panel, check all legs of the power leads. Determine that power is being supplied at the correct voltage. g) Check out reversing contactor and accelerating contactor sequencing.

Operate the hoist push button on the pendant control, step by step in both directions. At each step, check contactor sequence with sequence shown on panel wiring diagram for proper operation. h) Open mainline disconnect switch and replace fuses in the hoist motor circuit of the hoist panel.

4 of 6

i) Close mainline disconnect switch and reset mainline contactor by pressing the START button. j) Jog the hoist master switch or push button in the UP direction, Check to insure that the drum is rotating in a direction which would raise the load block. (Refer to reeving instructions), to determine drum direction for rising).

If direction is wrong, correct by interchanging any two leads at motor conduit box. Be certain main disconnect switch is open (power off)

when making this correction.

k) Operate the hoist several revolutions of the drum in both direction, observing that the motor brake releases properly, and that the gear train and bearings operate without binding. l) After the hoist is reeved and before placing trolley in service, a confirming load test is recommended under the direction of an appointed qualified person.

Hoist Limit Switch Test: (no load)

After the hoist is completely reeved, the upper and lower (if so equipped) limit switches must be checked for proper operation and safe stopping distance. a) Set upper and lower limits of load block. b) Slowly raise the load block. Observe the relationship of the load block to the underside of the trolley. The hoist limit switch should stop the upward travel of the load block with a few inches.

WARNING

Do not contact or strike trolley frame with load block. If hoist motion is not interrupted by limit switch, stop hoist by depressing the STOP button.

c) If the limit switch does not stop the load block, or if stopping distance exceeds several inches check electrical circuit against wiring diagram, determine cause and correct. Also check brake torque adjustment. d) Repeat test increasing the speed until test ifs performed at full speed.

5 of 6

WARNING

Distance required to stop the load block after tripping the limit switch increases with speed. Be certain that the limit switch trips soon enough so that the load block will not contact the trolley frame or other obstruction in stopping.

e) If trolley is equipped with a lower limit switch, check switch rip setting by lowering load block until motor stops. With load block in extreme low position, two full wraps of rope must be on the drum. a) At the trolley control panel, check all legs of the power leads. Determine that power is being supplied at the correct voltage. b) Check reversing contactor and accelerating contactor sequencing by operation of the trolley push button on the pendant control in both directions.

Check sequence with panel wiring diagram to determine proper operation. c) Open mainline disconnect switch and replace fuses in the trolley motor circuit of the trolley panel. d) Close mainline disconnect switch and reset mainline contactor by pressing the START button.

CAUTION

When operating the trolley motion, place load block in high position and watch out for overhead or side interferences between the building and the crane.

e) Jog trolley master switch in the forward direction (be sure trolley is free to move in either direction). If direction of trolley is incorrect, reverse lead as described under Hoist Test above. f) Operate the trolley slowly across the entire bridge and slowly contact the end stops. Check contact of bumpers or wheels to end stops. Operate several times back and forth across the bridge avoiding contact with end stops, working the unit up to full speed. Observe that the gear train and bearings operate without binding and that the trolley travels across the bridge without skewing.

LUBRICATION INSTRUCTIONS

LUBRICATION

Lubrication is accomplished by the splash system. The oil level is set high enough to partially submerge all gears, and in some cases, the bearings. In some cases splash feed lubrication fills oil pockets at bearings on all shafts and thereby maintains a reservoir of oil at these points.

TYPE OF LUBRICANT

Use CHEVRON MEROPA ISO 220 or equal.

If ambient temperatures drop below 35

0

F, gearbox oil must be changed to ISO

150 MINERAL GEAR OIL.

If ambient temperatures remain BELOW 0

0

F, an oil heater will have to be installed.

OIL SEALS

Oil seals require a small amount of lubricant to prevent frictional heat and subsequent destruction when the shaft is rotating. Oil seals often permit a slight seepage of oil along the sealing surfaces. This seepage is required to minimize seal friction and heat.

OIL CHANGES

After the initial six (6) months of operation, the original oil should be changed.

Very often, due to the wearing-in process, small metal particles will appear in the oil; this is not abnormal. Fill the housing to the indicated level with straight mineral flushing oil which must not contain additives. Start gearbox and bring up to operating speed (preferably without load) and then stop. Drain flushing oil and fill with recommended operating lubricant to proper level.

Unusual environmental or load conditions may necessitate replacement of oil as frequently as one (1) or two (2) month intervals as determined by field inspection.

Special attentions must be given to the inspection of lubricants when following conditions exist: a) High operation temperatures resulting from heavy intermittent loads, causing the temperature of the gear housing to rise rapidly and then cool. b) Ambient temperature conditions which may cause sweating on the inside wall of the gear housing, contaminating the oil and forming sludge.

Page 1 of 2

Precautions must be taken to prevent any foreign matter from entering the gearbox housing. Dust, dirt, moisture and chemical fumes form a sludge which is detrimental to proper and adequate lubrication. Ace World Companies must be advised before manufacture of gearbox when environmental conditions are anticipated.

3-1 GENERAL

 

a) The importance of safe handling of overhead hoisting cannot be overstated. The operator should be aware at all time that he is in control of a powerful machine, which if used carelessly, can do a great deal of damage. Correct usage is fundamental to reliable operation and minimum maintenance costs of the trolley.

One measuring stick of a good operator is his smoothness of operation. Jumpy of jerky trolley movement, flying starts, quick reversals and sudden stops are the trade marks of the carless operator. b) Equally important to the safe operation of the trolley is frequent and systematic inspection and maintenance. Mandatory requirements on a national level are detailed in OSHA Part 1910.179. The user should become familiar with those regulations, along with any other state or local codes.

 

a) Safe and efficient trolley operation requires skill, extreme care, good judgment, alertness, concentration, knowledge of and rigid adherence to proven safety rules and practices. No person should be permitted to operate a trolley:

1) Who is not qualified or has handicaps that could adversely affect such operation.

2) Who has not been properly instructed?

3) Who has not been informed and does not have thorough knowledge of all applicable safe operating practices, including those in this book as well as rigging equipment and practices. b) The user is also referred to American National Standard ANSI B30.2.0 Section 2-

3.1 for qualification and conduct of operators. Additionally, the user should become familiar with National, State or Local safety codes which may apply.

 

WARNING

Page 2 of 9

Equipment covered herein is not designed or suitable as power source for lifting or lowering persons.

 

 

Safe operation of an overhead hoist is the operator’s responsibility. Listed below are some basic rules that can make an operator aware of dangerous practices to avoid and precautions to take for his own safety and the safety of others. Observance of these rules in addition to frequent examinations and periodic inspection of the equipment may save injury to personnel and damage to equipment.

a) DO

1) Read ANSI B30.2.0 Safety Standard for Overhead and Gantry Cranes.

2) Be familiar with hoist operating controls, procedures and warnings.

With forearm vertical, and forefinger pointing up, move hand in small horizontal circle.

With arm extended downward, forefinger pointing down, move hand in a small horizontal circle.

Arm extended forward, hand open and slightly raised, make pushing motion in direction of travel.

Hold up one finger for block marked ”1” and two finger for block marked “2”.

Palm up, fingers closed, thumb pointing in direction of motion, jerk hand horizontally.

Use one hand to give any motion signal and place other hand motionless in front of hand giving the motion signal.

Page 6 of 9

Arm extended, palm down,hold position rigidly.

Arm extended, palm down, move hand rapidly right and left.

Crane operator spreads both hands apart – palms up.

The operator should locate and be familiar with the operation of the runway mainline disconnect switch and for this exercise lock switch in the OPEN (power off) position.

The operator should now manipulate the various push buttons to get the “feel” and determine that they do not bind or stick in any position. The operator should become familiar with the location of the buttons or switches for their respective motions, as well as the “START” and “STOP” buttons which operate the mainline contactor. The

“STOP” buttons should be used in any emergency since it will shut off power to all motions.

WARNING

If a push button binds or sticks in any position or does not return to the OFF position – do not turn power on – determine the cause of malfunction and correct before operating trolley.

3-6.1 Close the mainline disconnect switch. Press the START button. The trolley is now under power and ready to operate. For descriptive purposes assume the trolley is push button controlled with three speed points. Be certain the area is clear of all obstructions and people.

3-6.2 Hoist motion. Depress the “Down” push button to the first speed point.

Observe that the load block is moving down slowly.

If the load block does not start down, depress the push button to the second speed point to start the load block in motion, and then back off to the first speed point. This

Page 7 of 9

may occur if the hoist is new or has been idle for a period of time. If the load block still does not move on the first speed point after an initial break-in period, the hoist secondary resistance can be modified. This should be done only after consultation with ACE WORLD COMPANIES electrical department.

With the load block moving downward, push to the 2 nd

and finally to the 3 rd

(full speed) point of control observing the increase in speed as the button is depressed. With no load on the load block the speed change may be detectable only by the use of a tachometer.

Release push button and observe distance required to stop load block. The load block may be lowered until two full wraps of cable remain on the drum. Never lower load block below this position.

In the same manner, depress the “UP” push button to the first speed point, then to the

2 nd

speed point and finally to the 3 rd

(full speed point. Release push button and observe stopping distance. During this practice be certain to stop the load block several feet below the bottom of the trolley.

At the beginning of each shift the operator must check the hoist upper limit switch with no load. Extreme care must be exercised to avoid accidental damage in the event the switch does not operate. Raise the load block by slow inching. Carefully observe the relationship of the load block and the bottom of the trolley frame. The hoist upper limit switch, when working properly, should cause the host upward motion to stop.

WARNING

Do not contact or strike trolley frame, drum or upper block with load block. If hoist motion is not interrupted by limit switch, stop hoist. Do not attempt further operation. Report condition to proper supervisor for correction.

Repeat upper limit switch test described above several times, each time increasing the hoist speed until switch is tested at full speed. Do not use this upper limit switch as an operating control.

3-6.3 Trolley motion. The operator must develop complete familiarity with response of the trolley motion and direction relative to position of the controls. As with the hoist, the operator should become familiar with each speed point working to full speed ONLY after stopping from each speed point. This practice should continue ling enough so that direction speeds, stopping, distance, hook swing control, etc., become “second nature” to the operator’s judgment and reflexes.

Page 8 of 9

The exact same procedures apply with load as given in Para. 3-6 for no load. Start operation using a light load of 10 to 15 percent full load graduating to approximately

50% load and then to full load in three load steps. This will give the operator a feel for control response throughout the load range. The most important effect of a changing load with which the operator must become familiar is the variation of stopping distance required.

Motor torque in the first speed point is limited to approximately 50 percent and therefore the hoist will not raise or lower loads exceeding approximately 50 percent of the rated load while on the first speed point.

Page 2 of 3

START-UP PROCEDURE

The gearbox unit has been test run at the factory; however, during initial start-up, perform the following recommended procedures: a) Electrical motor starting must be arranged to start gearbox slowly to avoid severe impact loads. Across the line starting of motors must be applied with caution to prevent instantaneous gear loads greatly in excess of rating. b) If the gearbox is equipped with heaters c) Starting gearbox slowly and under as light a load as possible. d) Check for oil leaks.

OPERATIONAL CHECKS

a) As the gearbox is brought up to normal operating speed, it must be checked constantly for unusual sounds, excessive vibration, excessive heat or oil leakage. If any of these problems develop, the gearbox must be stopped immediately and the cause determined and corrected. b) After start-up the gearbox should be operated until temperatures stabilize.

PREVENTIVE MAINTENANCE

GENERAL

The preventive maintenance instructions are presented as scheduled procedures and provide the information necessary for prolonging the life of the gearbox and for the prevention and detection of gearbox failures before actual failure takes place. The majority of gearbox failures can be attributed to improper lubrication, misapplication and misalignment.

Improper lubrication is a prime cause of gear failures. Too frequently, units are started up without a lubricant. Conversely, the unit sometimes has a larger volume of oil than is specified in the mistaken belief that better lubrication is obtained. A higher volume of oil usually results in more of the input power going into churning of the oil, creating excessive temperatures with detrimental results to gears and bearings. Insufficient lubrication causes the same results.

Gear failure due to overload is a broad and varied area of misapplication of the gear train. The nature of load (input torque, output torque, duration of operating cycle, chocks, speed, acceleration, braking, frequent starts and stops, etc.) determines the gear unit size and other design criteria. If there is any question that the actual service conditions may be more severe than originally anticipated, consult Ace World Companies before start-up. Often there are remedies that can be suggested before the gearbox is damaged by overload, but none are effective after severe damage.

The hoist should be analyzed while the gearbox is under a full load condition to determine that the hoist is not overloaded and thus putting out more than rated torque. If it is determined that overload does exist, the unit should be stopped and steps taken to either remove the overload or contact Ace World Companies to determine suitability of the gearbox under observed conditions.

SCHEDULED MAINTENANCE

DAILY:

The gearbox must be routinely inspected for unusual sounds or visible oil leaks. If either occurs, the gearbox must be stopped immediately, and the cause determined and corrected.

Page 1 of 2

After the first 100 hours of operation, all external housing and mounting bolts should be torque to make certain they have not loosened. Check all piping connections and tighten if necessary.

WEEKLY

Check oil level and add oil if necessary.

Check the alignment of the gearbox with connected machinery after initially operating for 4 weeks under load. a) Are all mounting bolts torque to correct tightness? b) Is all housing and cap bolts torque to correct tightness. c) Is gearbox correctly alignment with other equipment. d) Is any excessive torque or overhung loads placed on gearbox.

TWO MONTHLY INTERVALS

Check oil for contamination.

SIX MONTH OR 2500 HOUR INTERVALS

Change oil in gearbox.

EXTENDED SHUTDOWN PERIODS

If it becomes necessary to shut down for a period longer than 25 weeks, the gearbox must be operated for at least 15 minutes during each week that it is idle.

This periodic operation will keep the gears and bearings coated with oil and will prevent rust due to condensation of moisture resulting from temperature changes.

ASSEMBLY AND DISASSEMBLY PROCEDURES

ASSEMBLY PROCEDURES

CAUTION

Assembly should only be done by qualified personnel experienced with this type of machinery. Before starting work they should review the service manual and familiarize themselves with the assembly, parts list, and drawings. All safety precautions must be observed. Personal injury or equipment damage could result if these precautions are not observed.

TIPS FOR ASSEMBLY

Hoist of sufficient capacity to handle the parts must be available in the area where the unit will be assembled.

Slings should be used when handling machined parts. Clean up the area around the gearbox before assembly to keep parts clean. Sufficient space should be available to lay parts out in proper order for assembly.

Move gearbox to a clean prepared area for assembly when possible. Before starting assembly, carefully review assembly, parts lists, and drawings. Inspect the gearbox.

DISASSEMBLY PROCEDURES

To disassemble gearbox proceed as follows:

Hoists of sufficient capacity to handle the parts must be available in the area where the unit will be disassembled.

Slings should be used when handling machined parts. Clean up the area around the gearbox before disassembly to keep parts clean. Sufficient space should be available to lay parts out in proper order for assembly. Remember that parts are usually disassembled in reverse order of assembly. Provide wooden blocks or skids for storing machined parts to prevent damage to machined parts.

Motor Trouble-Shooting Chart

Caution:

1. Disconnect power to the motor before performing service or maintenance.

2. Discharge all capacitors before servicing motor.

3. Always keep hands and clothing away from moving parts.

4. Be sure required safety guards are in place before starting equipment.

Problem:

Motor fails to start upon initial installation.

Motor has been running, then fails to start.

Motor runs but dies down.

Like Causes:

Motor is miswired.

Motor damaged and rotor is striking stator.

Fan guard bent and contacting fan.

Fuse or circuit breaker tripped.

Stator is shorted or went to ground. Motor will make a humming noise and the circuit breaker or fuse will trip.

Motor overloaded or load jammed.

Capacitor (on single phase motor) may have failed.

Starting switch has failed.

Voltage drop.

Load increased.

Motor takes too long to accelerate.

Defective capacitor

Faulty stationary switch.

Bad bearings.

Voltage too low.

Motor runs in the wrong direction.

Motor overload protector continually trips.

Incorrect wiring.

Load too high.

Ambient temperature too high.

Protector may be defective.

Winding shorted or grounded.

What To Do:

Verify motor is wired correctly.

May be able to reassemble; otherwise, motor should be replaced.

Replace fan guard.

Replace fuse or reset the breaker.

Disassemble motor and inspect windings and internal connections.

A blown stator will show a burn mark. Motor must be replaced or the stator rewound.

Inspect to see that the load is free. Verify amp draw of motor versus nameplate rating.

First discharge capacitor. To check capacitor, set volt-ohm meter to

RX100 scale and touch its probes to capacitor terminals. If capacitor is OK, needle will jump to zero ohms, and drift back to high. Steady zero ohms indicates a short circuit; steady high ohms indicates an open circuit.

Disassemble motor and inspect both the centrifugal and stationary switches. The weights of the centrifugal switch should move in and out freely. Make sure that the switch is not loose on the shaft.

Inspect contacts and connections on the stationary switch.

Replace switch if the contacts are burned or pitted.

If voltage is less than 10% of the motor’s rating contact power company or check if some other equipment is taking power away from the motor.

Verify the load has not changed. Verify equipment hasn’t got tighter. If fan application verify the air flow hasn’t changed.

Test capacitor per previous instructions.

Inspect switch contacts and connections. Verify that switch reeds have some spring in them.

Noisy or rough feeling bearings should be replaced.

Make sure that the voltage is within 10% of the motor’s nameplate rating. If not, contact power company or check if some other equipment is taking power away from the motor.

Rewire motor according to wiring schematic provided.

Verify that the load is not jammed. If motor is a replacement, verify that the rating is the same as the old motor. If previous motor was a special design, a stock motor may not be able to duplicate the performance. Remove the load from the motor and inspect the amp draw of the motor unloaded. It should be less than the full load rating stamped on the nameplate.

Verify that the motor is getting enough air for proper cooling. Most motors are designed to run in an ambient temperature of less than

40°C. (Note: A properly operating motor may be hot to the touch.)

Replace the motor’s protector with a new one of the same rating.

Inspect stator for defects, or loose or cut wires that may cause it to go to ground.

Motor Trouble-Shooting Chart

10/13/00 (continued)

Problem:

Motor vibrates.

Bearings continuously fail.

The motor, at start up, makes a loud rubbing or grinding noise.

Start capacitors continuously fail.

Run capacitor fail.

Like Causes:

Motor misaligned to load.

Load out of balance.

(Direct drive application.)

Motor bearings defective.

Rotor out of balance.

Motor may have too much endplay.

Winding may be defective.

Load to motor may be excessive or unbalanced.

High ambient temperature.

Rotor may be striking stator.

What To Do:

Realign load.

Remove motor from load and inspect motor by itself. Verify that motor shaft is not bent. Rule of thumb is .001" runout per every inch of shaft length.

Test motor by itself. If bearings are bad, you will hear noise or feel roughness. Replace bearings. Add oil if a sleeve of bearing.

Add grease if bearings have grease fittings.

Inspect motor by itself with no load attached. If it feels rough and vibrates but the bearings are good, it may be that the rotor was improperly balanced at the factory. Rotor must be replaced or rebalanced.

With the motor disconnected from power turned shaft. It should move but with some resistance. If the shaft moves in and out too freely, this may indicate a preload problem and the bearings may need additional shimming.

Test winding for shorted or open circuits. The amps may also be high. Replace motor or have stator rewound.

Besides checking load, also inspect drive belt tension to ensure it’s not too tight may be too high. An unbalanced load will also cause the bearings to fail.

If the motor is used in a high ambient, a different type of bearing grease may be required. You may need to consult the factory or a bearing distributor.

Ensure that motor was not damaged in shipment. Frame damage may not be repairable. If you cannot see physical damage, inspect the motor’s rotor and stator for strike marks. If signs of rubbing are present, the motor should be replaced. Sometimes simply disassembling and reassembling motor eliminates rubbing.

Endbells are also sometimes knocked out of alignment during transportation.

The motor is not coming up to speed quickly enough.

The motor is being cycled too frequently.

Voltage to motor is too low.

Motor may not be sized properly. Verify how long the motor takes to come up to speed, Most single phase capacitor start motors should come up to speed within three seconds. Otherwise the capacitors may fail.

Verify duty cycle. Capacitor manufacturers recommend no more than 20, three-second starts per hour. Install capacitor with higher voltage rating, or add bleed resistor to the capacitor.

Verify that voltage to the motor is within 10% of the nameplate value. If the motor is rated 208-230V, the deviation must be calculated from 230V.

Replace switch.

Starting switch may be defective, preventing the motor from coming out of start winding.

Ambient temperature too high.

Possible power surge to motor, caused by lightning strike or other high transient voltage.

Verify that ambient does not exceed motor’s nameplate value.

If a common problem, install surge protector.

NSTRUCTIONS

The MF2C rotary limit switch is an electromechanical device for low voltage control circuits (EN 60947-1, EN 60947-5-1) to be used as electrical equipment on machines (EN 60204-1) in compliance with the fundamental requirements of the Low Voltage Directive 73/23/CEE and of the Machine

Directive 89/392/CEE.

The limit switch is designed for industrial use and also for use under particularly severe climatic conditions (operational temperature from

–25 °C to +70 °C, suitable for use in tropical environment). The equipment is not suitable for use in environments with potentially explosive atmosphere, corrosive agents or a high percentage of sodium chloride (saline fog).

Oils, acids or solvents may damage the equipment. Use the fixing holes on the base (29) to mount the limit switch. The use of special couplings (30, 32), flexible shafts or special driving systems (not supplied) are recommended for eliminating any misalignment between the limit switch shaft (35) and the reduction gear shaft to which it is connected. After loosening the central screw (04) use the screws (09, 12, 13) to adjust the operating point of the cams (08); once the cams are adjusted, tighten the central screw (04).

The switches (07) are designed for auxiliary control of contactors or electromagnetic loads (utilisation category AC-15 according to EN 60947-5-1).

The switches (07) have positive opening operation contacts (EN 60947-5-1).

Do not connect more than one phase to each switch (07). Do not oil or grease the control elements (08) or the switches (07). For easy wiring, the set of cams-switches (22) may be removed by loosening the screws (18) on the lower fixing plate; do not loosen the screws on the upper part of the set of cams-switches (01) in order not to take apart the switches; after wiring is completed, the set of cams-switches (22) must be properly fixed and screwed, paying attention to the coupling of the hexagonal plastic bushes (14, 39).

The installation of the limit switch shall be carried out by an expert and trained personnel. Wiring shall be properly done according to the current instructions.

Prior to the installation and the maintenance of the limit switch, the main power of the machinery shall be turned off.

Steps for the proper installation of the limit switch

• loosen the fixing screw (19) and remove the cover (20)

• connect the limit switch shaft (35) to the reduction gear shaft; to avoid any misalignment between the two shafts the use of couplings (30, 32), flexible shafts or special driving systems is recommended

• fix the limit switch firmly in place to prevent abnormal vibrations of the equipment during operation; use only the fixing holes on the base (29) to fix the equipment

• insert the cable into the limit switch through the cable clamp (27)

• strip the cable to a length suitable for wiring the switches (07)

• tape the stripped part of the cable

• clamp the wire into the cable clamp (27)

• connect all the switches (07) according to the contact scheme printed on the switches (use 6.3 mm Faston taps)

• adjust the operating point of the cams (08); for proper adjustment, loosen the central screw (04) of the cam set, adjust the operating point of each single cam (08) by turning its screw (09, 12, 13) (the numbers on the screws refer to the cams counting from bottom to top), then tighten the central screw (04)

• close the limit switch checking the proper positioning of the rubber (21) in the cover (20)

Periodic maintenance steps

• check the proper tightening of the screws (19) and cover (20)

• check the proper tightening of the central screw (04) holding the cams

• check the wiring conditions (in particular where wires clamp into the switch)

• check the proper positioning of the front (33) and rear (28) bush covers

• check the conditions of the rubber (21) fit between the cover (20) and the base (29) and check the tightening of the cable clamp (27) around the cable

• check that the limit switch enclosure (20, 29) is not broken

• check the alignment between the limit switch shaft (35) and the reduction gear shaft

• check that the limit switch is properly fixed

In case any component of the limit switch is modified, the validity of the markings and the guarantee on the equipment are annulled. Should any component need replacement, use original spare parts only.

TER declines all responsibility for damages caused by the improper use or installation of the equipment.

Subject: Electro Shear Oil Levels for 2700 – 3600 RPM’s

AWC, thank you for your interest in oil level parameters in applications operating at higher rpm’s than your standard 1800 RPM’s. The operation of Electro Shear brakes incorporates the oil shear technology – which allows for shearing of the oil to generate torque , as well as the cooling and lubrication of discs , which allows any heat build up to dissipate through the cast aluminum housing.

The following has been the standard oil levels for the brakes we have furnished you, using your standard 1800 RPM’s:

Electro Shear Model 8725 w/ full disc stack: oil level is 1.5 “ above the centerline.

Electro Shear Model 8727 w/ full disc stack: oil level is @ centerline.

Based upon our ‘typical application history ‘the following oil levels should be maintained when running 2700 – 3600 RPM’s:

Electro Shear Model 8725 w/ full disc stack: oil level should be @ 1.5 “ below centerline.

Electro Shear Model 8727 w/ full disc stack: oil level should be @ 1.5 “ below centerline.

Electro Shear Brake temperatures are a key measuring point of operation: Temperatures should not exceed 200 degrees F; with an optimum high temperature of 180 degrees F.

Cordially,

Midwest Brake

The A02H encoder is used for AC Vector motor and general industrial applications. For AC Vector motor applications, the encoder should be electrically isolated from the motor chassis to minimize encoder bearing currents and ground noise. An isolation insert for the hub is provided with the encoder by specifying B0 in the "special insert option" decode. When ordering isolation inserts separately, choose option A0 with a bore diameter of 38 mm.

For general industrial applications, isolation is not required and the decode for "special insert options" can be left blank.

INSPECTION OF UNIT

Thoroughly inspect the equipment for any shipping and handling damage before accepting shipment from the freight company. If any of the goods called for in the bill of lading or express receipt are damaged or the quantity is short, do not accept until the freight or express agent makes an appropriate notation on your freight bill or express receipt. If any concealed loss or damage is discovered later, notify your freight carrier or express agent at once and request him to make an inspection. We will be very happy to assist you in collecting claims for loss or damage during shipment; however, this willingness on our part does not remove the transportation company’s responsibility in reimbursing you for collection of claims or replacement of material. Claims for loss or damage in shipment must not be deducted from the NORD Gear invoice, nor should payment of the NORD Gear invoice be withheld awaiting adjustment of such claims, as the carrier guarantees safe delivery.

If considerable damage has been incurred and the situation is urgent, contact the nearest NORD Gear Sales Office for assistance. Please keep a written record of all communications.

RECORD NAMEPLATE DATA

Locate the gear reducer nameplate and record all nameplate data for future reference.

SK ________________________________________________________ S/N _________________________________

RATIO ______________ MAX TORQUE ____________________ RPM ______________ MTG. POS ______________

PROPER STORAGE UNTIL INSTALLED

Keep unit in a dry, temperature controlled area. If stored other than said, long term storage methods must be applied to the unit including complete fill with lubricant. Protect machined surfaces and rotate shafts periodically. Prior to putting unit into service, drain lubricant and refill to proper level as determined by the mounting position.

STORAGE

PROPER HANDLING OF THE UNIT

Exercise care to prevent damage to the unit when moving. Lift onIy at designed Iifting points. Do not attach other machinery and lift by the unit lifting points. The lifting points are to be used to lift the unit only. Insure that adequate safety measures are taken to protect personneI during transportation. Protect the mounting surface from damage.

BIM 1020/2005/03 Page 1 of 12 www.nord.com

INSTALLATION OF UNIT

To ensure Iong service and dependabIe performance, an encIosed gear drive must be rigidIy supported and the shafts accurateIy aIigned.

The foIIowing describes the minimum precautions required to accompIish this end.

FOUNDATION

The responsibiIity for the design and construction of the foundation Iies with the user. The foundation must be adequate to withstand normaI operating Ioads and possibIe overIoads whiIe maintaining aIignment to attached system components under such Ioads.

MOUNTING POSITION

UnIess a unit is specificaIIy ordered for incIined mounting, the foundation must be IeveI and fIat. The Iubrication system may not operate properIy if the unit is not mounted in the position for which it is designed. It may be desirabIe to eIevate the foundation to faciIitate oiI drainage.

FOOT MOUNTED UNITS

Use shims under the feet of the unit to aIign the output shaft to the driven equipment. Make sure that aII feet are supported so that the housing wiII not distort when it is boIted down. Improper shimming wiII reduce the Iife of the unit and may cause faiIure.

DoweI pins may be instaIIed to prevent misaIignment and ensure proper reaIignment if removed for service.

BOLT STRENGTH

BoIt size, strength and quantity shouId be verified to insure proper torque reaction capacity whatever the mounting arrangement.

LUBRICATE SHAFTS

Both the hollow shaft and the driven shaft should be liberally lubricated before assembly. The unit must slide freely onto the driven shaft. Do not hammer or force the unit into place. For shrink disc, follow instructions below.

AXIAL RETENTION

Each drive shaft must be retained in place relative to the gear reducer. Or each gear reducer must be retained in place relative to the drive shaft. Either way NORD recommends the use of shaft shoulders, locking collars or FIXING ELEMENTS to axially retain the shaft or gear reducer in position.

SET SCREWS

If set screws are used for axial retention, they should be tightened evenly. Flats may be filed on the driven shaft and a threadlocking adhesive used for more position retention.

SNAP RING RETENTION

Placing external snap rings on drive shafts must be performed with caution. The groove, which the snap ring fits into, may weaken the drive shaft causing premature failure. NORD does not recommend this type of shaft retention.

THRUST PLATE

In applications, which are subject to high vibratory loads, a thrust plate will provide greater resistance to axial movement. Follow the manufacturer’s recommendations for assembly.

SHRINK DISC

If a shrink disc is used to secure a reducer hollow shaft to the driven shaft, follow this assembly procedure. Start with the shrink disc mounted onto the extension of the hollow shaft disc locking bolts loosened.

1. Clean reducer bore and mating solid shaft to be free of any lubricants or dirt.

2. Slide reducer onto the solid shaft until it is about half way through.

3. Lubricate the remaining portion of the solid shaft with a #2 grease or similar lubricant. This part will be located under the bronze bushing. Do not install grease under the

shrink disc gripping area. Finish installing the solid shaft into the reducer hollow bore.

4. Finger tighten all shrink disc bolts. Now, moving a circular pattern, tighten each shrink disc locking bolt 1/4 to 1/2 turn.

Do not use criss cross pattern. Continue tightening in the same circular direction with 1/4 or 1/2 turn increments until all bolts reach the specified bolt tightening torque. Bolt tightening torque is shown on the shrink disc label for the particular unit.

5. Run unit for 24 hours, then retighten shrink disc locking bolts to the proper bolt torque as indicated above.

TORQUE REACTION ARM

On the shaft mount ‘Clincher’, torque is reacted through the integral torque tab, which is part of the casting. Commonly,

NORD’s optional RUBBER BUFFER bushings are installed on each side of the integral torque tab to dampen torque shocks and allow for mis-alignment received from the machinery during operation.

Torque arm connection fabrications should always be mounted perpendicular to a line through the output shaft center and the point at attachment of the torque arm to the unit housing. In this position the minimum load on the attachment structure arm will be experienced. The attachment structure must be rigid and may not deflect under any load. Doing so will place extra loads on the output bearings of the reducer.

PRIME MOVER MOUNTING

AIign the prime mover to the reducer-input shaft using shims under the feet. Make sure that the feet are supported. DoweI the prime mover to its foundation.

SHAFT CONNECTIONS

When connecting shafts to either the input or output of the reducer, consider the foIIowing instructions.

FITS

CIearance or interference fits for coupIing hubs shouId be in accordance with ANSI/AGMA 9002-A86 or as follows.

°F to 300°F, (120°C to 150° C) before assembIing to the shaft.

LOCATION

CoupIing hubs shouId be mounted fIush with the shaft ends, unIess specificaIIy ordered for overhung mounting. Pinions, sprockets and sheaves shouId be mounted as cIose as possibIe to the unit housing to minimize bearing Ioads and shaft defIections.

Page 3 of 12 www.nord.com

COUPLING ALIGNMENT

Shaft coupIings shouId be instaIIed according to the coupIing manufacturer’s recommendations for gap, anguIar and paraIIeI aIignment. In many instaIIations, it is necessary to aIIow for thermaI and mechanicaI shaft movement when determining shaft aIignment. The coupIing manufacturer’s recommendations shouId be foIIowed.

AXIAL DISPLACEMENT

The gap between shaft ends shouId be the same as the specified coupIing gap unIess overhung mounting of the coupIing hub is specified. The coupIing gap and shaft gap must be sufficient to accommodate any anticipated thermaI or mechanicaI axiaI movement.

ANGULAR ALIGNMENT

Insert a spacer or shim stock equaI to the required coupIing gap between the coupIing hub faces and measure the cIearance using feeIer gauges. Repeat this at the same depth at 90-degree intervaIs to determine the amount of anguIar misaIignment.

PARALLEL ALIGNMENT

Mount a diaI indicator to one coupIing hub, and rotate this hub, sweeping the outside diameter of the other hub. The paraIIeI misaIignment is equaI to one-haIf of the totaI indicator reading.

Another method is to rest a straight edge squareIy on the outside diameter of the hubs at 90-degree intervaIs and measure any gaps with feeIer gauges. The maximum gap measurement is the paraIIeI misaIignment.

CHECKING ALIGNMENT

After both anguIar and paraIIeI aIignments are within specified

Iimits, tighten aII foundation boIts secureIy and repeat the above procedure to check aIignment. If any of the specified Iimits for aIignment are exceeded, reaIign the coupIing.

SPROCKET OR SHEAVE ALIGNMENT

AIign the sheaves or sprockets square and paraIIeI by pIacing a straight edge across their faces. AIignment of bushed sheaves and sprockets shouId be checked after bushings have been tightened. Check horizontaI shaft aIignment by pIacing a IeveI verticaIIy against the face of the sheave or sprocket. Adjust beIt or chain tension per the manufacturer’s specified procedure.

OUTBOARD PINION ALIGNMENT

AIign the pinion by adjusting the gear tooth cIearance according to the manufacturer’s recommendations and checking for acceptabIe outboard pinion tooth contact. The foundation boIts may have to be Ioosened and the unit moved sIightIy to obtain this contact. When the unit is moved to correct tooth contact, the prime mover shouId be reaIigned.

RECHECK ALIGNMENT

After a period of operation, recheck aIignment and adjust as required.

1. Properly install unit on a rigid foundation

• adequateIy supported

• secureIy boIted into pIace

IeveIed so as not to distort the gear case

2. Properly install couplings suitabIe for the application and connected equipment.

3. Ensure accurate aIignment with other equipment.

4. Furnish and install adequate machinery guards as needed to protect operating personneI and as required by the appIicabIe standards of the OccupationaI Safety and HeaIth

Administration (OSHA), and by other appIicabIe safety reguIations;

5. Ensure that driving equipment is running in the correct direction before coupling to reducers with backstops

(designed to operate onIy in a specific direction) or machinery designed to operate only in one direction.

CHANGES IN PERFORMANCE SPECIFICATIONS

Owner has the responsibiIity to consult with NORD GEAR if such items such as applied Ioads, operating speeds or other operating conditions have changed.

WARNING:

LOCK OUT POWER before any maintenance is performed.

Make absolutely sure that no voltage is applied while work is being done on the gearbox.

START-UP

1. Ensure that switches, aIarms, heaters, coolers and other safety and protection devices are instaIIed and operational for their intended purpose.

2. Verify that the installed mounting position is the same as the nametag mounting position. If not, adjust the oil level accordingly and relocate the vent plug, fill plug and drain plug according to the mounting position. See following.

AUTOVENT PLUG

The Autovent plug is brass in color and will be located at the highest point on the gearbox. It operates like a check-valve to allow the reducer to relieve internal pressure while preventing lubricant contamination during cooling. A spring presses a ball or plunger against a machined orifice until pressure exceeds 2 psi.

Above 2 psi the air is allowed to escape depressurizing the gearcase. When internal pressure drops below 2 psi, the autovent re-seals closing the unit to the outside environment.

After shutdown, the reducer cools along with the air inside the reducer. The unit will temporarily maintain a slight vacuum until normalization occurs. NORD Gear supplies an Autovent as a standard feature. inside the gearbox (Max. pressure 2 psi).

Page 4 of 12

The Autovent releases built-up air pressure from www.nord.com

FILL LEVEL & DRAIN PLUGS

The drain plugs are metric socket head cap screws. They will be located at the lowest part of the gearbox for ease of draining. The fill level plug is a hex head cap screw. It will be located between the Autovent and drain plug. Both types of plugs will have gaskets included to prevent oil from leaking.

Two types of plugs for maintenance

LUBRICANT

AII NORD reducers are shipped from the factory properIy fiIIed with Iubricant and all plugs are installed according to the mounting position given on the reducer nametag. Acceptable oil fill level is within ½ inch of the bottom of the fill plug threads.

OPERATION AND MAINTENANCE CHECKLIST

1. Operate the equipment as it was intended to be operated

2. Do not overIoad.

3. Run at correct speed.

4. Maintain Iubricant in good condition and at proper IeveI.

5. Dispose of used Iubricant in accordance with appIicabIe

Iaws and reguIations.

6.

AppIy proper maintenance to attached equipment at prescribed intervaIs recommended by the manufacturer.

7. Perform periodic maintenance of the gear drive as recommended by NORD.

MOUNTING POSITIONS

BIM 1020/2005/03 Page 5 of 12 www.nord.com

MAINTENANCE

Mineral lubricant should be changed every 10,000 service hours or after two years. For synthetic oils, the lube should be changed every

20,000 service hours or after four years. In case of extreme operating (e.g. high humidity, aggressive environment or large temperature variations), shorter intervals between changes are recommended.

OIL SPECIFICATIONS

NORD supplies aII reducers fiIIed with oiI from the factory. Consult the sticker adjacent to the fill plug to determine the type of lubricant installed at the factory. Standard lubricant is ISO VG220 mineral-based oil. However, some units have special lubricants designed to operate in certain environments or to extend the service life of the lubricant. If in doubt about which lubricant is needed, contact NORD Gear.

GENERAL DESCRIPTION

BRAKES

General

NORD brakes are “spring set”. When power is removed from the brake, the brake will automatically set to hold the load. NORD brakes are DC voltage brakes and in most instances are supplied with a motor mounted brake rectifier for easy connections to AC power. AC power is taken directly from the power line or from the terminal block of the motor and converted to DC by the supplied rectifier in the terminal box. If the motor is connected to a

frequency inverter, soft start, or is a two-speed motor, the AC power must be supplied to the brake rectifier separately from the motor power.

When the brake is de-energized (Power Off), the braking springs exert a force against the anchor plate, which prevents the brake rotor from rotating. When the brake coil is energized (Power On), a magnetic field builds and pulls the anchor plate across the air gap to the brake casing, which frees the brake rotor and allows the motor shaft to rotate.

NORD Gear typically use brakes manufactured by Precima and

Mayr. The Mayr brake is used mainly on the 20Nm and some of the 400-1200Nm sizes. For questions regarding brake manufacturer, please contact NORD Gear.

Standard Rectifiers

As standard, NORD integral gearmotors with a DC brake include a rectifier mounted in the motor terminal box to supply DC power to the brake. The rectifier can be wired for switching either the

AC power source or the DC voltage supply (output). Wiring the

DC switching gives the fastest reaction (de-energize – brake engage – stopping) time. If AC switching is used, the source power can be attached to the motor brake terminals. Tapping into the motor terminals gives the slowest de-energize time (stopping), due to the collapsing time of the motor magnetic field.

RECTIFIERS

General

The DC power required to energize the brake is not available in most applications. AC power is available in all applications since it is required to power the motor. The rectifier converts the available AC voltage to the DC voltage needed to power the brake.

Features

• Individual power supply for each motor.

Compact size; mounted inside motor terminal box.

• Multiple voltage options

Solid state bridge rectifier

Integral protection against transient voltage spikes

• Half wave rectifier:

DC voltage is 45% of the applied AC voltage

Full wave rectifier:

DC voltage is 90% of the applied AC voltage

RECTIFIER PART NUMBERS & RATINGS

Special Function Rectifiers & Current Sensing Relays

NORD offers special function rectifiers (Option FR) which provide improved brake performance. Refer to “BIM 1095 FR Brake

Rectifier” for more information.

Another way of improving brake performance is using NORD’s current sensing relay (Option IR). It requires no external wiring and screws into the spare side hole of the conduit box. Refer to

“BIM 1092 IR Relay” for more information.

Cautions

Brake torque - The brake torque is measured with a mean friction radius of the brake pad surface with a circumferential speed of 1m/sec (197 fpm).

Brake torque tolerance - For different applications and operating conditions, brake torque can vary from +40/-20% compared to the rated brake torque.

Hoisting (lifting/lowering) applications - must have the brake wired for fast response (DC-switching)

Initial operation & wear-in period - In new condition, the brake will have a reduced torque of up to 30%. In order to achieve full rated brake torque, a short run-in period is required. The run in time will vary depending on system loads.

BIM 1090/2008/02 Page 3 of 12 www.nord.com

MAINTENANCE – PRECIMA BRAKES

General

In order to get maximum life out of the brake, the air gap must be set properly and checked at regular intervals. As the brake wears and decreases in thickness, the air gap will increase. If the air gap is too large, the brake coil may not have enough magnetic force to pull the metal armature disc across the gap and the brake rotor will drag. Refer to the table below for maximum air gap allowance and minimum brake pad thickness.

Brake Air Gap Adjustment:

When a complete brake motor is supplied by NORD, the air gap is already set at the factory. If the brake is ordered as a part, the air gap must be set at the time of assembly. All brake air gap adjustments must be made with the brake assembled onto the motor and power off

(Brake Engaged). If the brake has an optional hand release (Option HL), refer to page 9 for additional instructions.

While checking the air gap, measure the gap around the socket head cap screws as shown in the picture below.

Loosen the socket head cap screw that attaches the brake to the motor B-endbell.

Depending if the air gap needs to be increased/decreased, turn the adjusting nut accordingly. A quarter or half turn is usually sufficient for adjusting purposes.

After adjusting the nut, tighten the socket head cap screw back onto the brake.

Measure the air gap for spacing - Repeat process to achieve recommended setting.

Rubber Dust Boot (Option SR)

The optional rubber dust boot protects the brake from dusty/sandy debris from reaching the brake pad. However, it also keeps the brake dust from getting out. Regular maintenance must be done to the brake to remove the brake dust. The amount of brake dust accumulated will vary with the brake size and application.

BRAKE PAD REPLACEMENT – PRECIMA BRAKES

LIST OF TOOLS

Following are a list of tools to remove the brake:

• Screw drivers – Philips & Flat (to remove the fan cover)

External snap ring pliers (to remove fan retaining snap ring)

• Large screw drive or a small pry bar (to pop off the fan)

Metric sockets & T-handles and open-end wrenches

IMPORTANT

Ensure that the reducer load is supported. Removal of the brake will let the load free fall, which may cause injury.

Disconnect the power from the motor.

PROCEDURE

When the brake pad is worn to the minimum thickness as shown in the chart on page 5, the pad should be replaced to maintain the proper operation. To replace the pad:

• Remove the 4 bolts to remove the fan cover

If the brake has a hand release, this can be removed by unscrewing.

Remove the fan cover and note the position of the hand release slot if applicable.

• Remove the snap ring holding the cooling fan.

Carefully remove the cooling fan, key and second snap ring.

If the brake is equipped with a dust boot, remove it.

Remove the 3 socket head cap screws holding the brake coil to the motor end-bell.

Remove the brake coil, noting the hand release and power cable locations.

• The brake pad will now slide off the hub holding it on the shaft.

Clean the brake, install the pad and reassemble.

NOTE: Upon reassembly, the brake air gap setting must be checked and adjusted if needed, as noted in MAINTENANCE.

This style brake needs very little maintenance while it is in operation.

The air gap does not need to be adjusted. It is pre-set at the factory and is self adjusting for the life of the brake rotor pad. When the brake is not operation properly, the rotor pad may need to be replaced. The brake coil will have to be removed to check the brake pad thickness.

IMPORTANT

Ensure that the reducer load is supported. Removal of the brake will let the load free fall, which may cause injury.

Disconnect the power from the motor.

PROCEDURE

Remove the 4 bolts to remove the fan cover.

• If the brake has a hand release, it can be removed by unscrewing it.

Remove the fan cover and note the position of the hand release slot if applicable.

• Remove the snap ring holding the cooling fan in place.

Carefully remove the fan, key and second snap ring.

Remove the 3 socket head cap screws holding the brake coil to the motor endbell.

• Remove the brake coil, noting the hand release and power cable locations.

The brake pad will now slide off the hub holding it on the shaft.

• Clean the brake coil, replace the pad, and reassemble.

NOTE: The air gap is self adjusting and can not be measured with the brake assembled. To check the proper operation, apply pressure to the hand release lever and turn the motor by hand to check for free rotation.

IMPORTANT

Ensure that the reducer load is supported. Removal of the brake will let the load free fall, which may cause injury.

Disconnect the power from the motor.

PROCEDURE FOR CHECKING AND ADJUSTING THE AIR GAP

Remove the 4 bolts to remove the fan cover.

• Remove the fan cover.

Remove a plug from the threaded distance ring (31) and measure the air gap with a feeler gauge. If the distance is larger than

0.012”/0.3mm over the nominal setting listed in the table, the air gap should be adjusted.

• Loosen the fixing screws (13)

Loosen the locking screw (59) and lock washer (60).

Turn the threaded distance ring counterclockwise to decrease the air gap. One graduation on the stamped scale corresponds with

.004”/0.1mm.

Tighten the fixing and clamp screws and recheck the air gap.

• If the air gap is within specifications, reassemble the fan cover.

PROCEDURE FOR REPLACING THE BRAKE ROTOR PAD

Remove fan cover and snap ring.

• Carefully remove the fan, key and second snap ring.

Remove the 3 socket head cap screws holding the brake coil to the motor endbell.

• Remove the brake coil.

The brake pad will now slide off the hub holding it on the shaft.

Clean the brake coil, replace the pad, and reassemble.

NOTE: Check the air gap per the above procedure.

HAND RELEASE BRAKE AIR GAP SETTING

When a complete brake motor is supplied by NORD, the brake air gap and hand release lever spacing are already set from the factory. Only the brake air gap will need to be adjusted for maintenance (Precima Brakes). Refer to the brake air gap setting on page 4. Thread adhesive is applied to the hand release adjusting bolt so it will not lose the setting. The spacing for the hand release can be checked only with the brake assembled onto the brake B-endbell. If the spacing needs to be adjusted, remove the brake from the motor B-endbell and the adjusting bolt will be accessible. Refer to Figure 1. *20Nm Mayr brake air gaps do not need adjustment.

If the brake is sent by itself from the factory, the brake air gap and hand release lever spacing must be set. If the air gap is set less than recommended, the brake will lose holding force prematurely. If very little air gap is set, the brake will not engage. Setting the brake air gap must be done with the brake removed from the motor. The “new” brake air gap value will be the sum of the brake air gap value and the hand release spacing value. After the gap has been set, assemble the brake onto the motor and measure both the brake air gap and hand release spacing with a feeler gauge. Refer to Figure 2.

ADJUSTING BRAKE TORQUE

The table below shows the rated torque of brakes as springs are removed (7, 5 or 3 springs). The springs are placed in such a way where there are three centers and four outer springs. The four outer springs are the ones that are removed for decreasing the torque. When decreasing the torque, remove springs opposite of each other to prevent uneven brake wear.
