Valworx electric actuators are 100% tested to ensure

trouble free installaon and operaon.

PROBLEM POSSIBLE CAUSE SOLUTION

Actuator will not open or close during

inial startup

 Incorrect voltage or power connecon.  Conrm correct voltage is being applied to gray

connector and power connecon is wired

correctly. Neutral or negave (-) must be

connected to PIN 1. Do not apply more than 25.2

volts to the 12-24 volt actuators (24volts +5%).

 Incorrect control signal input. This must be an

industry standard analog input control signal.

Do NOT connect a baery or variable power

supply directly to the control signal input. This

will damage the control circuit board.

 Conrm actuator is setup for correct input (4-

20mA or 0-10vdc). Conrm control signal wiring is

correct per wiring diagram and instrucons

 Undersized power supply  This is a motor circuit, therefore power supply

should be sized at least 3 mes 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 compable with

the actuator

 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 will not power up, LED on top

of actuator does not turn ON

 Excessive power surge and/or an over voltage

condion. Damaged circuit board.

 LED light should be ON when power is applied. If

actuator was damaged by a power surge or over

voltage condion, 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”

Actuator will not complete the cycle

5610 series LED blinking on-o, on-o

5616 series LED blinking red or green

 Over-torque (possible valve jam).  Remove over-torque condion, repower and

retry

 Main control board or motor failure  Replace with new actuator or return to factory for

evaluaon and/or possible repair

Actuator powers ON but will not

complete cycle

 Control board or motor failure  Replace with new actuator or return to factory for

evaluaon.

 Manual override selector lever in ‘AUTO’ mode  Move manual override selector to ‘MAN’ mode

Cannot turn the manual override knob

 Excessive force applied to manual override

knob, this may have damaged the gear drive

 If aer selecng ’MAN’, manual override sll does

not work, replace with a new actuator

 Valve jam  Clear valve jam and try again
