2. The cable assembly (E3156025) to the rotary encode is securely connected. Each rotary encoder has a finger
release on the connector to disconnect the 5pin cable assembly from the encoder.
3. Verify the continuity of the encoder cable assembly E3156025.

used)
4. Monitor the output signals on the 5pin connector on the A1 board for each encoder in question.
5. The channel A and channel B outputs should transition from 0v to 5v while a lead screw is rotating and 5v
power should be present between pin 1(-) and pin 4(+) on the 5 pin connector on each encoder.
6. Verify that the plastic encoder disk is secured firmly on the lead screw by the set screw in the mounting collar.
7. Refer to the attached encoder manufactures instructions to verify the alignment of the encoder using the
alignment tool supplied by the manufacturer to properly align the plastic optical disk with the sensor assembly.
8. Replace the encoder assembly (E1480801) if the output signals do not transition correctly or if the plastic optical
disk appears to be damaged.
