Internal fault
Reset W-FM, see [ch. 9.1].
If the error occurred during a parameter
change:
Check parameter that was last changed for
plausibility.
If the reset does not achieve a fault free con-
dition:
Load data from the ABE [ch. 6.16.1].
If none of the actions listed leads to a fault
free condition:
Replace W-FM.
