Lincoln 1100 Series Optical Encoder Assembly, Remove gearmotor assembly see “GEARMOTOR” Above

Page 57

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

2.Pull the coupling apart (approximately 1/8",3.2mm) and fasten the motor side set screw.

3.Install the optical encoder, 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.

4.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.Remove gearmotor assembly (see “GEARMOTOR”) Above.

2.If replacing with new assembly, cut wires to remove as new wires and plug are provided. If only removing for access to coupling, see step 3.

3.Remove pins from connector 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.

7.To adjust optical encoder:

a.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.

TACH. GENERATOR

1.Turn off power at main breaker.

2.Remove gearmotor assembly (see “GEARMOTOR”)

3.Remove tach. cover plate and tach. leads. Mark wires for reassembly.

4.Remove 2 slotted screws from dust cover base and remove dust cover.

5.Loosen coupling set screw (.050 inch allen wrench).

6.Remove tach. bracket from motor. (4 screws)

7.Remove 4 screws from base of tach. and tach. is now free for removal.

8.Reassemble in reverse order. Maintain spacing of .010 minimum between tach.bracket and coupler hub. NOTE: If a new tach. generator is installed, the D.C. motor control board MUST BERECALIBRATED. There is no repair procedure for the tach. If defective, replace.
