Description
1600 Speed input
(Pickup)
2 [On] Speed monitoring of the engine is
carried out by the MPU or via ECU/
J1939.
Off Speed/frequency monitoring of
the generator set (the engine) is
performed by measuring the
frequency of the generator.
15155 Engine speed source 2 [Internal] The internal MPU input is used as
engine speed source.
ECU/J1939 An external ECU/J1939 signal is
used as speed source.
1602 Fly wheel teeth 2 2 to 800
[118]
Number of pulse per revolution/
teeth on the flywheel.

4.4.1.4 Idle Mode
General notes
When the engine is operated at idle speed, undervoltage, underfrequency, and
underspeed monitoring as well as the monitoring of the flexible limits 33 through 40 are
not performed.
This function allows for a controlled operation of an engine without alarm messages at a
lower speed (below the configured underspeed 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.
The idle mode can be only used if the function is supported by the ECU or the frequency
controller.
