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

Generator Overfrequency (Level 1 & 2) ANSI# 81O
General notes
This controller provides the user with two alarm levels for generator overfrequency. Both
alarms are definite time alarms.
Monitoring for overfrequency faults is performed in two steps.
If this protective function is triggered, the display indicates "Gen. overfrequency 1" or
"Gen. overfrequency 2" and the logical command variable "06.01" or "06.02" will be
enabled.
╚═▷ “9.1.1 Triggering Characteristics”
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.
