[Default]
2 [On] Overfrequency monitoring is carried out according to the following parame‐
ters. Monitoring is performed at two levels. Both values may be configured
independent from each other (prerequisite: limit 1 < Level 2 limit).
Off Monitoring is disabled for Level 1 limit and/or Level 2 limit.
2 50.0 to 130.0 % The percentage values that are to be monitored for each threshold limit are
defined here.
2854: [100.4 %]
If this value is reached or exceeded for at least the delay time without inter‐
2860: [120.0 %]
ruption, the action specified by the alarm class is initiated.
Notes
This value refers to the System rated frequency (parameter
2 0.02 to 99.99 s If the monitored mains frequency value exceeds the threshold value for the
delay time configured here, an alarm will be issued.
2855: [0.06 s]
2861: [0.06 s]
Notes
If the monitored mains frequency falls below the threshold (minus the hyste‐
resis) before the delay expires the time will be reset.
2 Class A/B/C/D/ Each limit may be assigned an independent alarm class that specifies what
E/F action should be taken when the limit is surpassed.
2851: [A]
2857: [B]

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.
