Delayed Monitoring and Ignition Speed
Parameter
239
Monitoring on
after 00s
Delayed monitoring
0 to 99 s
Any parameters configured for delayed monitoring (e.g. oil pressure, generator un-
derfrequency, etc.) will not be assessed until the expiration of the time configured
here. This timer starts when the control unit detects that the engine has reached fir-
ing speed.
Parameter
240
Monitoring on
at f gen > 00Hz
Ignition speed
15 to 70 Hz
The user configures the point that the engine firing speed has been reached. Once
the controller detects this, the frequency controller assumes speed control.
Note
: Measurement is only possible above 15 Hz, even if 5 Hz are displayed.
