Response to error detection
All channels that are in pause mode on "PE_MODE_PROCEED" report their diagnostic
status as in productive mode.
The following applies for all channels which switch to a different pause mode:
● During the "pause", error detection of "Load voltage 2L+ missing" is not possible:
– Alarms for errors already pending before the "pause" are retained.
– After the "pause" is over, the error status is updated and incoming/outgoing errors are
