Remedy
Check or replace Power Module.
CE
Check the line voltage at the input terminals.
Check the line voltage setting (p0210).
● Check whether the fan is running.
● Check the fan filter elements.
● Check whether the ambient temperature is in the permissible range.
See F30035 and, in addition:
● Check the motor load.
● Check the line phases
Check the internal fan and if required replace.
Replace the Power Module or upgrade the Control Unit firmware.
Replace the Power Module.
Check the internal fan and if required replace.
There is a communications fault between the Control Unit and the Power
Module. Possible causes:
● The Control Unit may have been removed or inserted incorrectly.
● The external 24 V Control Unit power supply has dipped to ≤95% of the
rated voltage for ≤3 ms
● Check the device supply voltage (p0210).
● Check the line reactor dimensioning
Switch the Control Unit off and on again, upgrade the firmware or contact
technical support.
Switch the Control Unit off and on again, upgrade the firmware or contact
technical support.
Check that the sensor is connected correctly.
A PROFINET control is attempting to establish a connection with an incor‐
rect configuration telegram. Check whether "Shared Device" is activated
(p8929 = 2).
Correct the name of station (p8920) and activate (p8925 = 2).
a PROFINET control is available.
