Monitoring for this fault condition
is continuously enabled.
87.70 LM:Eng.mon
Monitoring for fault conditions is
not performed until engine
monitoring is enabled. This is
determined through the
LogicsManager equation "Release
engine monitoring".
For xx = 1 to 32:
96.{xx}
LM: Flag{xx}
The monitoring is executed, if the
LogicsManager "Flag {xx}" is
TRUE.
Example:
96.01 LM: Flag 1, 96.02 LM: Flag
2, ..., 96.32 LM: Flag 32

General notes
Voltage is monitored according to how the parameter "Generator voltage measuring"
(parameter
) is configured. This controller provides the user with two alarm
levels for generator undervoltage. Both alarms are definite time alarms.
Monitoring for undervoltage faults is performed in two steps.
If this protective function is triggered, the display indicates "Gen. undervoltage 1" or
"Gen. undervoltage 2" and the logical command variable "06.07" or "06.08" will be
enabled.

for the triggering characteristic of this
monitoring function. The diagrams listed there show a frequency trend and the associated
pickup times and length of the alarms.
The parameter limits listed below have identical setting ranges. Each parameter may be
configured with different settings to create unique trip characteristics for specific
thresholds.
This monitoring function is disabled when the idle mode (
