How to troubleshoot Eltorque Controller actuator with no response and no LED indicator?
If your Eltorque Controller actuator isn't responding, and the LED indicator is off, it likely indicates a power supply issue. Start by checking the fuses and wiring. Use a voltage meter to verify the supply voltage; it should be between 110-230V AC (L-N).
What to do if Eltorque Controller actuator gives torque alarm and attempts to move valve?
If your Eltorque Controller actuator's alarm output is active, giving a torque alarm, and the actuator tries to move the valve, it could be due to the valve operation torque being too high, or the actuator torque setting being too low. Manually check the valve torque, watching out for obstructions in the pipe. If the torque is normal, increase the actuator torque using E3C, or via CANopen communication on CANopen systems.
Why is the Eltorque QT50 actuator's alarm output active and giving temperature alarm?
If the Eltorque Controller actuator's alarm output is active, giving a temperature alarm, and the actuator isn't responding to control signals, it could be overheating. Ensure the surrounding temperature is within specified limits and that you're adhering to duty type requirements. For more details, refer to section 5.2 Error alarms and error handling on page 46.
What to do if Eltorque Controller actuator gives status signal emergency?
If the Eltorque Controller actuator's alarm output is active, giving a status signal emergency, and the actuator isn't being operated manually, it suggests the self-locking device isn't locking properly. Check that the position is configured correctly and that the torque setting is sufficient for the valve. If issues persist, contact your local Eltorque agent for support.
How to troubleshoot Eltorque QT50 actuator with CANopen interface that doesn't respond to control signals?
If an Eltorque Controller actuator with a CANopen interface isn't responding to control signals, but works with E3C, the fieldbus settings might be incorrect. Verify the configuration using E3C.
