3) Check routing of wires and plug them into the controller. Connectors will snap in place. Be sure that wires are

properly managed through the clips on top plate. This will prevent the wires from being caught in the camshaft.

4) Place bottom of module in position. The bottom will ﬁ t into a clip.

5) Pivot the top into position and snap in place. The controller should be secure.

If you are ready to program the controller, then power can be applied by plugging in transformer.

DRIVE MOTOR

The drive motor is open loop and receives commands from the control module. The motor has a pinion gear that

meshes with the camshaft gear to drive (rotate) the camshaft.

During operation, rotation forces the motor into its mounting position and screws or bolts are not needed.

NOTE: Some units will have a shipping peg in the top motor mount. The peg can be removed and dis-

carded. This peg is not required for motor operation.

To remove motor:

1) Disconnect power to the unit.

2) Remove cover.

3) Pull off wiring connector.

4) Grasp the motor body and rotate to the left.

5) Pull motor out.

To install motor:

1) Insert gear through hole on top plate

2) With motor ears ﬂ at to the rear of the top plate, rotate to the right until mounting tabs are engaged in slots.

3) Reconnect wires.

NOTE: It is not necessary to pre-position the camshaft or the motor. When the controller is powered up

the camshaft will be rotated to the “home” position.

OPTICAL SENSOR

The optical sensor is mounted to the top plate. The camshaft cup rotates through the sensor and the slots are

detected. A signal is sent to the controller for each slot.

NOTE: Damaged sensors should be replaced. Sensors may be cleaned with compressed air or a soft brush.
