In my maintenance site I have 10 AUMA Actuator AC 01.2 which are showing IE24V and Phase fault alarm.
Almost all actuator facing this issue, sometime Its reset automatically and appeard again.

Have anyone maybe experience similar challenges???

 

Found the issue yet?

I had a whole subset of actuators with a phase fault, it came down to a loose bus bar in the power panel for that set of actuators. Are you able to check the mains voltage at the power AUMA wiring terminations?

 

The IE24V alarm usually indicates an issue with the 24V control voltage. This can happen due to an insufficient or fluctuating supply voltage.

 

Check this one
