Multi-Voltage On/Off Electric Actuators
POSSIBLE CAUSE

Incorrect wiring of the gray DIN power
connector

No suitable switching device

Incorrect voltage being supplied to actuator

Power supply is not sized large enough

Actuator does not have an isolated circuit or is
connected in parallel with other actuators or
equipment

Controls or controller is not compatible with
the actuator. Leakage current from solid state
relays or contacts may cause actuator
malfunction.

Incorrect wiring of the gray DIN power
connector

Excessive power surge and/or an over voltage
condition. Damaged main circuit board.

Actuator may be in the manual mode

Over-torque (possible valve jam).

Main control board or motor failure


Rewiring the gray DIN power plug per the
actuator electrical diagram and instructions.

Customer to supply a SPDT mechanical relay or a
3-way 2-position manual switch to open and close
the 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
(24volts +5%).

This is a motor circuit, therefore power supply
should be sized at least 3 times full load current.

Actuator should have its own fused and isolated
circuit. Do not connect actuators in parallel or
with other equipment on the same circuit.

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.

Neutral or minus (-) power lead MUST be
connected to PIN 1 on gray power connector
(polarity sensitive).

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

Move "MAN" selector lever to "AUTO"

Remove over-torque condition, repower and try
again

Replace with new actuator or return to factory for
evaluation and/or possible repair
