Potentiometer
Removal

9. Remove the white plastic actuator position-indicating dial by gently pulling while

rotating in the clockwise direction. See Figure 6.

10. Disconnect the blue, black and brown wire from the potentiometer terminal block. See

Figure 17.

11. Remove the silver potentiometer alignment screw.

12. Loosen the black potentiometer cam attachment screw approximately one turn.

13. Gently wedge a small screwdriver between the potentiometer and the gray plastic

housing.

14. Carefully twist the screwdriver until the potentiometer releases from the cam drum

shaft. Remove the ASZ… potentiometer.

Potentiometer
Installation

1. Install the new ASZ… potentiometer by gently sliding the bushing over the cam drum

shaft.

2. Align the potentiometer alignment screw hole with the hole in the gray plastic housing

and install the potentiometer alignment screw. See Figures 17 and 17a.

3. The actuator position indicating pointer, located near the actuator gear end of the cam

drum, must point to the “0” mark on the actuator position scale. See Figure 6. The
scale is located on the cam drum nearest to the actuator gear end. Press and hold
the black cam drum release button while manually rotating the cam drum.

4. If installing a potentiometer without gear, manually rotate the potentiometer pointer

until the pointer is

exactly

in the “min” position. See Figure 17. Firmly tighten the

black potentiometer cam attachment screw while manually holding the potentiometer
pointer in alignment. Check the alignment again.

5. If installing a gear model potentiometer, manually rotate the potentiometer gear until

the white line next to the “0” or “1” mark on the potentiometer gear face is

exactly

in

alignment with the potentiometer gear alignment pointer. See Figure 17a.
For counterclockwise (ccw) operation the line beside the “1” mark must exactly align
with potentiometer gear alignment pointer. For clockwise (cw) operation the line
beside the “0” mark must exactly align with potentiometer gear alignment pointer.
Firmly tighten the black potentiometer cam attachment screw while manually holding
the potentiometer gear in alignment. Check the alignment again.

6. Connect the bundled blue, black and brown potentiometer wires to the terminal block

located on the ASZ… potentiometer board. See

Potentiometer Installation

and

Figures 17 and 17a.

7. Re-install the white actuator-indicating dial by gently pressing it onto the

potentiometer cam attachment screw. Align scale position “0” on the actuator position
indicating dial with the dial pointer by rotating the dial in the clockwise direction to
avoid loosening the potentiometer gear attachment screw. See Figure 6.
