1. Remove 4 bolts securing the top cover for the pulser. Use care to prevent nicks or scratches on the mating

surfaces between the top cover and the pulser body (this is a UL flame path).

2. Remove the cotter pin that engages the pulser shaft to the plastic gear.

3. Disconnect the connector from the top of the optical encoder.

4. Grasp the rectangular body of the optical encoder and turn CLOCKWISE to loosen. These are LEFT

HAND THREADS. Remove optical encoder from assembly

5. Slide fiber washer over the new encoder shaft and install the encoder by turning COUNTER-CLOCKWISE.

Tighten securely by hand.

6. The optical encoder comes in two different styles. The function of these is the same, however their physical

shapes are slightly different. Before reinstalling the connector, determine the type of optical encoder that

you have.

• If the encoder has a silver metal housing, the connection

should be made so that the wires are routed over the top of

the encoder (Fig. 1)

• If the encoder has a black plastic housing, the connection

should be made so that the wires are routed around the side

of the encoder (Fig. 2). The position of the encoder pins will

vary depending on where they are when the encoder is in its

tightened position. In some cases, it is possible that the wire

leads are too short to allow the connector to reach. If this

occurs, try a different encoder. If this still does not resolve the

issue, you must replace the entire pulser/conduit assembly

rather than just the optical encoder.

7. Reinstall the cotter pin and bend in a manner that does not cause

interference with the top of the gear that drives the pulser shaft

(Fig. 3).

8. Reassemble top cover ensuring that the connector wires are not

pinched in the mating surface.
