N.B.: any intervention must only be carried out by a qualified electrician or persons instructed in accordance with the regulations of electric engineering, safety, and all other applicable directives

Step 1: open the actuator cover (if the actuator is ATEX, IECEx or EACEx, bring it in a non-explosive area).

For ER PREMIER, ER PLUS, VR(X), VS(X), MT or VT PLUS, are the leds of the main board on?
For VT, ensure voltage presence at terminals 1 and 2 or 1 and 3.
For 3-phase 400V, ensure voltage presence at terminals A, B and C as well as terminals 1 and 2 or 1 and 3.

Is the actuator powered?

Yes No

Step 2:

Is the actuator operates without rotating the valve?

Yes No Previous question

Step 3: Check the electric wiring (refer to electric diagrams of each actuator in the setup procedures).

Is the wiring correct?

Yes No Previous question

Step 4: check the overtorque.

For ER PLUS, VR(X), VS(X), MT et VT PLUS models, la diode "LED3", "ERROR" or "ERR" indicates an overtorque. It�s also possible to check the overtorque feedback relay (D1 and D2 terminals): closed contact = overtorque.
For VT(X) models, check the overtorque feedback relay (D1 and D2 terminals): closed contact = overtorque.
For other models which don�t have torque limiter, contact Valpes.

Is the actuator on overtorque?

Yes No Previous question

Step 5: check the microswitches levers.
The two lower microswitches control the motor (four lower microswitches for 3 positions actuators).

Are the levers glued?

Yes No Previous question

Step 6: operate manually the actuator (for VT(X) models, make sure that the power supply is of).

Is the manual override working?

Yes No Previous question

Step 7: separate the actuator and the valve and check again the manual override.

Is the manual override working?

Yes No Previous question

Step 8: make sure that the valve torque corresponds to its theoretical torque.

Is the valve torque correct?

Yes No Previous question

Step 9: check the actuator model.

Is the actuator torque higher or equal to valve torque x1.5?

Yes No Previous question

Step 3:

Is the actuator an ER or a VR?

Yes No Previous question

Step 4: check the clutch system.

Is the reduction correctly clutched (AUTO at the top)?

Yes No Previous question

Step 5: separate the actuator and the valve and check the coupling (the shaft height and the reduction sleeve if it�s needed).

Is the coupling correct?

Yes No Previous question

Step 2 : control the power supply.

Is there current in power supply cables?

Yes No Previous question

Step 3 : check the model number of the actuator.

Does the power supply voltage corresponds to actuator voltage?

Yes No Previous question

Step 4: Check the electric wiring (refer to electric diagrams of each actuator in the setup procedures)

Is the wiring correct?

Yes No Previous question

Step 4: Valpes multivolt actuators accept the following supply voltage ranges:

for ER PREMIER
   high voltage: 100V to 240V AC 50/60Hz and 100V to 350V DC
   low voltage: 24V AC 50/60Hz and 24V DC

for ER PLUS, VR(X) et VS(X)
   high voltage: 100V to 240V AC 50/60Hz and 100V to 350V DC
   low voltage: 15V to 30V AC 50/60Hz and 12V to 48V DC (FAILSAFE: 24V to 48V DC)

for MT et VT PLUS
   high voltage: 100V to 240V AC 50/60Hz and 100V to 300V DC
   low voltage: 24V to 48V AC 50/60Hz and 24V to 72V DC

For the other models, please contact us.

What is the supply voltage ranges of the actuator?

Proposed solution: a sticky substance may glues the microswitch. In this case, clean it to free the lever.

Exceptionally one or several microswitchs can break down. In this case, please contact our after sales service.

Return to FAQ

Proposed solution: the de-clutch button is intended for coming back into AUTO position. Otherwise, make it manually. Also, make sure that the actuator isn�t upside down.
