Safety First
In the maintenance and operation of mechanical equipment, safety is a basic factor that must be
considered at all times. By using proper clothing, tools and procedures, serious accidents to you and your
fellow workers can be prevented. After inspecting the actuator, keep the following information for future
reference.

CAUSE/CORRECTIVE ACTION
•
Interrupted power. Check for broken or loose wires, blown fuses or tripped
breaker. Check the limit switches to see if they are in the normal operating
positions.
•
Motor burnout. Check to insure that correct voltage has been applied. Check
all wiring against installation wiring diagrams.
•
Malfunctioning valve. Check that valve is operating properly.
•
Check the ambient temperature rating. The motor is a permanent
split capacitor type equipped with a thermal cut-out switch. Excessive
temperatures and cycle frequencies may heat the motor up and the thermal
cut-out turns off the motor.
•
Check frequency of operation. This electric actuator has a duty rating of 50%
(no more than 30 minutes run time out of every hour).
•
Low voltage "brown out" . Measure line voltage to insure that actuator is
receiving full rated voltage.
•
Motor stall. Check for foreign obstruction in valve. Check for increased
torque load due to line pressure, etc.
•
Low voltage or current. Check to insure that power supply is within listed
specifications.
•
Overheating. See erratic actuator performance above.
•
Refer to "Setting Cams For Alignment" in this manual.
•
Circuit not energized for full duration of cycle. Malfunction in control device
(relay, switch, etc.); inspect and correct or replace.
