PROBLEM
POSSIBLE CAUSE
SOLUTION
Actuator will not open or close during
initial startup
Incorrect wiring of the gray DIN power
connector
Rewiring the gray DIN power plug per the
actuator electrical diagram and instructions.
No suitable switching device
Customer to supply a SPDT mechanical relay or a
3-way 2-position manual switch to open and close
the actuator.
Incorrect voltage being supplied to actuator
Confirm correct voltage is being applied to the
actuator. Connecting incorrect voltage may
damage the actuator beyond repair. Do not apply
more than 25.2 volts to the 12-24 volt actuators
(25%).
Power supply is not sized large enough
This is a motor circuit, therefore power supply
should be sized at least 3 times full load current.
Actuator does not have an isolated circuit or is
connected in parallel with other actuators or
equipment
Actuator should have its own fused and isolated
circuit. Do not connect actuators in parallel or
with other equipment on the same circuit.
Controls or controller is not compatible with
the actuator. Leakage current from solid state
relays or contacts may cause actuator
malfunction.
If possible, bench test the actuator without user
controls or controller. This will help determine
whether there is a problem with the actuator or
the input control circuit.
Actuator (valve) will close, but will not
open during initial startup. Slow LED
blink with DC voltage models.
Incorrect wiring of the gray DIN power
connector
Neutral or minus (-) power lead
MUST
be
connected to PIN 1 on gray power connector
(polarity sensitive).
Actuator will not power up, LED on top
of actuator does not turn ON
Excessive power surge and/or an over voltage
condition. Damaged main circuit board.
LED light should be ON when power is applied. If
actuator was damaged by a power surge or over
voltage condition, replace with new actuator
Actuator runs but does not rotate
LED double blink or blinking orange
Actuator may be in the manual mode
Move “MAN” selector lever to “AUTO”
Over-torque (possible valve jam).
Remove over-torque condition, repower and try
again
Actuator will not complete the cycle
LED blinking on-off, red or green
Main control board or motor failure
Replace with new actuator or return to factory for
evaluation and/or possible repair
