381 Actuator dynamics is missing
The ÜP has not detected the required dynamics for
at least one actuator.
Problem: The actual position of the actuator has not
changed in the last 24 hours.
– Check air damper and gas damper for jamming.
– In case of stiffness, clean the damper and
make it smooth running again.
– Check the function of the actuator without
damper and replace if necessary.
– Reset fault and switch mains voltage OFF
and ON again.
– If the error still exists, replace the device.
