Description
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
4.5.2.2
Engine Underspeed (Level 1 & 2)
General notes
The speed measured by the magnetic pickup unit (MPU) is monitored for underspeed. If
the MPU is disabled or not available, the speed may only be monitored using the
generator underfrequency monitoring. If the MPU speed falls below the underspeed limits
the configured alarms will be initiated.
If this protective function is triggered, the display indicates "Underspeed 1" or
"Underspeed 2" and the logical command variable "05.03" or "05.04" will be enabled.

independent from each
other (prerequisite: Level 1
> Level 2).

(Reset Delay: 1 s)
The percentage values that are to
be monitored for each threshold
limit are defined here.
If this value is reached or
exceeded for at least the delay
time without interruption, the
action specified by the alarm class
is initiated.

falls below the threshold value for
the delay time configured here, an
alarm will be issued.
