Installation, Maintenance and Operation Manual
Problem Cause / Corrective Action
Actuator Stops • Interrupted power. Check for broken or loose wires. Blown fuses or tripped breaker. Check switches.
Operating
• Tripped thermal overload caused by overheating (see overheating below).
• Motor burnout. Check to insure that correct voltage type is in use. Check all wiring against
installation wiring diagrams.
• Malfunctioning valve. Check that valve is operating properly.
Overheating • Excessive duty cycle. Check duty cycle (frequency of operation). This electric actuator has a duty cycle
of 50% (actuator is energized no more than 50% of the time).
• Low voltage "brown out". Measure line voltage to insure that actuator is receiving full rated
voltage.
• Ambient temperature too high and/or heat being conducted through mounting hardware.
• Motor stall. Check for foreign obstruction. Check valve for proper operation. Check for increased
torque load due to line pressure, etc.
Low Torque • Low voltage or current. Check to insure that power supply is within listed specifications.
Output
• Overheating. See overheating above.
Incorrect Travel • Refer to "Cam Adjustment" in this manual.
or Operation
• Circuit not energized for full duration of cycle. Malfunction in control device (relay, switch, etc.),
inspect and correct or replace.
