CL Setting range Description
[Default]
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.
Current is monitored according to how the parameter "Generator
current measuring" (parameter
controller provides the user with three definite time alarm levels for
generator overcurrent faults.
Monitoring of the maximum phase current is performed in three
steps. Every step can be provided with a delay time independent of
the other steps.
Refer to

CL Setting range Description
[Default]
2 [On] Overcurrent monitoring is carried out according to the following parameters.
Monitoring is performed at three levels. All three values may be configured
independent from each other (prerequisite: Level 1 < Level 2 < Level 3).
Off Monitoring is disabled for Level 1 limit, Level 2 limit, and/or Level 3 limit.
2 50.0 to 300.0 % The percentage values that are to be monitored for each threshold limit are
defined here.
2204: [110.0 %]
If this value is reached or exceeded for at least the delay time without inter‐

ruption, the action specified by the alarm class is initiated.
2216: [250.0 %]
Notes
This value refers to the System rated frequency (parameter
2 0.02 to 99.99 s If the monitored generator current exceeds the threshold value for the delay
time configured here, an alarm will be issued.
2205: [30.00 s]
2211: [1.00 s]
2217: [0.40 s]
Notes
If the monitored generator voltage falls below the threshold (minus the hyste‐
resis) before the delay expires the time will be reset.
