Product Overview

Auxiliary Switch

Adjustment

The adjustable built-in SPDT auxiliary switch is actuated by the cam nearest to the back of the

actuator. Although it can be adjusted to operate at any point in the actuator rotation, it is factory

set to operate at approximately mid-stroke. This operating point may be changed by inserting a

screwdriver through the opening in the top plate directly behind the terminal block, and engaging

the screwdriver with the gear-like plastic disc. Turning the disc clockwise causes the switch to

operate nearer the counterclockwise end of actuator travel. Each click of the switch actuating

cam represents approximately 3 angular degrees change in operating point.

MAINTENANCE

A minimum of maintenance is required since the motor and gear train are submerged in oil

(BYZP-195) for continuous lubrication and cooling. If necessary to refill with oil, always use TAC

immersion oil, available in one quart cans (refill capacity - 1 to 1-1/4 pints). Oil level (with the

actuator upright) should be up to the edge of the oil fill hole which is located just left of the output

shaft.

REPAIR

None. Replace an inoperable actuator with a functional unit.
