Function

1. Check Operation:

a. Switch on Vac/dc power.
b. Allow the actuator shaft coupling to rotate from 0 to 90°.
c. Switch off Vac/dc power.
The actuator shaft coupling will return to the "0" position.
2. Check Spring Return:
a. Switch on Vac power.
b. Allow the actuator shaft coupling to rotate halfway.
c. Switch off Vac power.
The spring returns the actuator shaft coupling to the fail "0" position.
3. Check the Auxiliary Switch A:
a. Set the DMM dial to ohms (resistance) or continuity check.
b. Connect wires S1 and S3 to the DMM.
The DMM should indicate an open circuit or no resistance.
c. Switch on Vac power.
The DMM should indicate contact closure as the actuator shaft coupling
reaches the setting of switch A.
d. Connect wires S1 and S2 to the DMM.
The DMM should indicate open circuit or no resistance.
e. Switch off Vac power.
The DMM should indicate contact closure as the actuator shaft coupling
reaches the setting of switch A.
