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 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.
CL Setting range Description
[Default]
2 The unit can either monitor the wye voltages (phase-neutral) or the delta vol‐
tages (phase-phase). The monitoring of the wye voltage is above all neces‐
sary to avoid earth-faults in a compensated or isolated network resulting in
the tripping of the voltage protection.
[Phase - The phase-phase voltage will be monitored and all subsequent parameters
phase] concerning voltage monitoring "mains" are referred to this value (VL-L).
Phase - neutral The phase-neutral voltage will be monitored and all subsequent parameters
concerning voltage monitoring "mains" are referred to this value (VL-N).
All The phase-phase and phase-neutral voltage will be monitored and all subse‐
quent parameters concerning voltage monitoring "mains" are referred to this
value (VL-L & VL-N).
This setting is only effective if "Mains voltage measuring" (parameter
1853 Ä p.
Notes
WARNING: This parameter influences the protective functions.
Please be aware that if "Mains voltage monitoring" (parameter

"Mains Voltage Increase" on page 144 is used, that this function only moni‐
tors "Phase - neutral".
2 0 to 9999 s To end the emergency operation, the monitored mains must be within the
configured operating parameters without interruption for the minimum period
[20 s]
of time set with this parameter without interruption.
This parameter permits delaying the switching of the load from the generator
to the mains.
The display indicates "Mains settling" during this time.
