This functional input is used for connecting of an external device, which measures
the reactive power imported from the mains. The device is connected to the
controller via an analog input (e.g. -20 .. 20mA). The setpoint I/E-Qm meas must
be set to the ANALOG INPUT position for this case.
Analog input: LCD brightness
This functional input is used to adjust the backlight intensity of the IG-NT built-in
terminal (display) by an analog input (e.g. a potentiometer). If this input is
configured to a physical analog input or other value, the brightness adjusted by
buttons at the terminal is overriden by this analog input.
Analog input: RPM pick-up
This functional input is used for reading of the gen-set speed from other source
than pickup or generator frequency. This source is typically an ECU unit, which
provides the speed at the communication bus.
NOTE:
See also the chapter Engine speed measurement.
Analog input: Oil press
This functional input is used as an additional information whether the engine is
running or not. If you want to use this additional feature configure this input onto
the physical analog input where the oil pressure sensor is connected and adjust
the setpoint Starting POil to cca 50% of typical engine oil pressure at idle speed.
NOTE:
See also the chapter Running engine detection.
Analog input: Warming temp
This functional input is used for engine warming. See also the setpoint Warming
load.
Analog input: Fuel level
This logical analog input is used for evaluation of the Fuel theft alarm. Learn more
in the description of the setpoint MaxLevelDrop.
Analog input: PowerDerating1
This is the input into the Power derating block #1. See details about the function in
