3.20 Limit Switch Assembly Replacement

1. Unplug the unit, loosen the top shroud and remove the left shroud. If you are replacing the right limit switch

assembly, also remove the right shroud.

2 Unplug the motor from the controller board. The Left motor is the black plug, the Right motor is the white plug

(Refer back to Figure 3.6).

3. Unplug the limit switch assembly from the motor (Figure 3.39).

4. Using a Phillips screwdriver, remove the four (4) screws securing the limit switch unit to the motor assembly

(Figure 3.40), cut the small zip-tie, and remove the limit switch unit.

5. Position the new limit switch unit (Figure 3.41), attach it to the motor assembly with the Phillips screws, and

secure the cable with a zip-tie..

6. Reconnect the limit switches to the motor

7. Reconnect the motor to the controller board.

8. Replace the right shroud (if it was removed), then the left shroud, and reposition the top shroud; secure with

shroud screws.
