2 On Voltage increase monitoring is carried out according to the following parame‐
ters.
[Off] No monitoring is carried out.
2 100 to 150 % The percentage voltage value that is to be monitored is defined here.
[110 %] If the average voltage over 10 minutes is higher, the action specified by the
alarm class is initiated.

4 [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 condi‐
tion is no longer detected.
The alarm must be acknowledged and reset by manually pressing the appro‐
priate buttons or by activating the LogicsManager output "External acknowl‐
edgement" (via a discrete input or via an interface).
2 Yes Monitoring for fault conditions is not performed until engine delayed moni‐
toring is enabled. The engine monitoring delay time (param‐
eter
parameters assigned this delay.
[No] Monitoring for this fault condition is continuously enabled regardless of engine
speed.
2 On If the 10 minute voltage averages of all phases exceed the limit, the moni‐
toring is tripping.
[Off] If the 10 minute voltage average of at least one phase exceeds the limit, the
monitoring is tripping.
2 On Voltage increase monitoring does cause a decoupling.
[Off] Voltage increase monitoring does not cause a decoupling.
0 --- This visualization value shows the current 10 minute average voltage.
