CL Setting range Description
[Default]
2 [On] Speed monitoring of the engine is carried out by the MPU.
Off Speed/frequency monitoring of the generator set (the engine) is performed by
measuring the frequency of the generator. There is no MPU wired to this unit.
2 [Internal] The internal MPU input is used as engine speed source.
ECU An external ECU signal is used as speed source.
2 2 to 260 Number of pulse per revolution/teeth on the flywheel.

Notes
This parameter is only applicable if parameter
"Internal".
When the engine is operated at idle speed, undervoltage, underfre‐
quency, and underspeed monitoring as well as the monitoring of
the flexible limits 13 through 16 are not performed.
This function allows for a controlled operation of an engine without
alarm messages at a lower speed (below the configured under‐
speed monitoring values) for e.g. a warm-up operation with low
emission.
The frequency controller output does not control the idle speed; it
will remain in initial state position. The GCB cannot be closed in
idle mode.
A message may be output to a relay here using the LogicsManager
(Idle mode is active, command variable 04.15), e.g. as a signal for
a speed controller. The display indicates "Idle run active" during
idle mode.
