counterclockwise. Manually rotate shaft clockwise to
desired close position. Slowly rotate cam clockwise until
switch lever opens.
You should hear a light click. (To check using a multi-

Under normal operation, electric actuators require
no formal maintenance program.
Regularly scheduled inspections should be performed to
check for:
•
Actuator-to-valve misalignment
•
Damaged housing or mounting hardware
•
Worn, loose or shifted parts due to shock,
vibration, etc.
