Check that no alarm other than motor overheating is present.
Wait until the motor cools down and the normally closed (NC) contact of the
thermal switch automatically resets before trying to operate the actuator again.
Check that the number of operations per hour and their duration is suitable for the
actuator service (refer to the nameplate menu).
Check that the valve operating torque is within the range of the unit's designed
operating torque.
Always check for causes of abnormal operation.
Check that the manual de-clutch lever is not stuck in the manual operation position.
Rotate the handwheel a few degrees to remove any possible sticking between the
handwheel and the drive sleeve.
