If this protective function is triggered, the display indicates "Ph.rotation mismatch" and
the logical command variable "08.33" will be enabled.
This monitoring function is only enabled if system A voltage measuring (parameter 1851)
and system B voltage measuring (parameter 1853) are con󰈡gured to "3Ph 4W" or "3Ph
3W" and the measured voltage exceeds 50 % of the rated voltage (parameter 1766) or if
system A voltage measuring (parameter 1851) and system B voltage measuring
(parameter 1853) are con󰈡gured to "1Ph 2W". In this case, the phase rotation is not
evaluated, but de󰈡ned by the 1Ph2W phase rotation (parameter
1859).

2942 Self acknowledge 2 [Yes] The control unit automatically clears
the alarm if the fault condition is no
longer detected.
No The control unit does not
automatically reset the alarm when
the fault condition is no longer
detected.
The alarm must be acknowledged and
reset by manually pressing the
appropriate buttons or by activating
the LogicsManager output "External
acknowledgement" (via a discrete
input or via an interface).
2945 Monitoring lockable 2 Yes Monitoring for fault conditions is only
performed if "Lock Monitoring Status
24.40 is false".
[No] Monitoring for this fault condition is
continuously enabled regardless of
"Lock Monitoring Status 24.40".
