Electric Actuators with DPS Positioner
POSSIBLE CAUSE

Incorrect voltage or power connection.

Incorrect control signal input. This must be an
industry standard analog input control signal.
Do NOT connect a battery or variable power
supply directly to the control signal input. This
will damage the control circuit board.

Undersized power supply

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

Excessive power surge and/or an over voltage
condition. Damaged circuit board.

Actuator may be in the manual mode

Over-torque (possible valve jam).

Main control board or motor failure

Control board or motor failure

Manual override selector lever in 'AUTO' mode

Excessive force applied to manual override
knob, this may have damaged the gear drive

Valve jam


Confirm correct voltage is being applied to gray
connector and power connection is wired
correctly. Neutral or negative (-) must be
connected to PIN 1. Do not apply more than 25.2
volts to the 12-24 volt actuators (24volts +5%).

Confirm actuator is setup for correct input (4-
20mA or 0-10vdc). Confirm control signal wiring is
correct per wiring diagram and instructions

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.

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
retry

Replace with new actuator or return to factory for
evaluation and/or possible repair

Replace with new actuator or return to factory for
evaluation.

Move manual override selector to 'MAN' mode

If after selecting 'MAN', manual override still does
not work, replace with a new actuator

Clear valve jam and try again
