Potentiometer Adjustment

Accessory kit AM-332 contains a potentiometer. This potentiometer consists of a

spring-loaded, friction-driven, copper wiper arm with a contact that rides on a uniformly

wound wire resistance card. The standard card has a resistance of 100 Ω, and is to be used

only with a power supply which does not exceed 25 Vac. The electrical capacity of the

resistance card is approximately 3 watts. For a view showing features of such a

potentiometer, refer to Figure-1 for the internal view of an AM-342 accessory kit.

Adjust the potentiometer as follows:

1. With the accessory kit mounted onto the actuator, run the actuator to the CCW end

of its travel.

2. Manually position the wiper arm at the CCW end of the resistance card.

MAINTENANCE

The accessory kits require no maintenance.

Regular maintenance of the total system is recommended to assure sustained,

optimum performance.

FIELD REPAIR

None. Replace an inoperative accessory kit with a functional unit.
