5.Remove the sprocket from the conveyor motor shaft by loosening the set screws and sliding the sprocket off the shaft.

6.Unplug the wiring harness for the motor.

7.Disconnect the red and black wires from the terminals on the tach. generator which is mounted on the top of the D.C. conveyor motor. Note which terminal the red and black wires are attached to. (Reversing the polarity will cause motor to run wide open with no control from the speed pot.)

8.Remove the four (4) mounting bolts.

9.Remove dust cover, remove tach., tach. bracket, coupling, and optical encoder assembly for reinstallation on new motor assembly. (See pages 104 & 105)

10.Reassemble in reverse order and calibrate in the conveyor D. C. control board (See D. C. Motor Control Board - Calibration).

CONVEYOR MOTOR REPLACEMENT - STEPPER 1000 SERIES SN14975 AND ABOVE

1200 SERIES SN14792 AND ABOVE

1.Shut off power at main breaker.

2.Remove control panel top and front cover.

3.Remove the chain guard.

4.Remove the conveyor drive chain from the motor sprocket.

5.Remove the sprocket from the conveyor motor shaft by loosening the set screw and sliding the sprocket off the shaft.

6.Unplug the wire harness for the motor.

7.Unplug the wire harness for the hall effect sensor (mounted on motor) from the conveyor speed control.

8.Remove the four (4) mounting bolts and washers.

9.Reassemble in reverse order and calibrate the control board. (See Stepper Control-Adjustment) NOTE: New drive motors will come as an assembly with Magnet and Hall Effect Sensor. The magnet and sensor will also be available as a replaceable spare part. (When replacing the magnet be sure

to clean shaft and locate new magnet up against the shoulder on the shaft.)

COUPLING AND ENCODER DISC

1.Shut off power at main breaker.

2.Remove conveyor motor assembly .

3.Remove dust cover above motor.

4.Loosen both allen set screws (.050 inch allen wrench) located on coupling hub.

5.Remove 3 screws from tach. bracket, loosen the 4th.

6.Remove encoder assembly, see optical encoder assembly in following procedure. Pushing coupling down on motor shaft. Swivel tach. bracket aside and remove coupling. To install, push coupling on to motor shaft. The encoder disc must be nearest motor.

7.Refasten tach. bracket in proper alignment.

8.Tighten the set screw on the tach. side first maintaining the .010 minimum dimension between the coupling hub and tach.

9.Pull the coupling apart (approximately 1/8",3.2mm) and fasten the motor side set screw. If the optical encoder was loosened, refer to optical encoder in this section for adjustment. NOTE: The thin, slotted encoder disc must be handled with care so not to bend it.

10.Recheck tightness on the set screws to be sure they are tight. If available, LOC TITE (the removable kind) should be used to secure set screws.

OPTICAL ENCODER ASSEMBLY

1.Shut off power at main breaker.

2.Remove conveyor motor assembly .If replacing with new assembly, cut wires to remove as new wires and plug are provided. If only removing for access to coupling follow step 4.

3.Remove pins from connectors with pin extractor tool, P/N 369600.

4.Loosen dust cover screws and pull dust cover away from motor.

5.Remove 2 screws from optical encoder and remove encoder.

6.Reassemble in reverse order.

To adjust optical encoder: Position the encoder assembly so it does not rub the coupler hub and is square with the encoder disc. The infrared light beam will be broken by slots in the encoder disc. The encoder disc should not touch the bottom or top of the optical encoder. If it does readjust the coupling. The digital speed readout may be observed to check proper adjustment of the optical encoder assembly.
