Analog inputs
LdCtrl:AnExBld
External requested gen-set power value.
• Configure LdCtrl:AnExtBld to selected analog input
• Configure Analog input range
• Adjust ProcessControl: Load ctrl PTM = ANEXT BASELOAD
LdCtrl:AnExI/E
External requested mains import/export power value.
• Configure input LdCtrl:AnExI/E to selected analog input
• Configure Analog input range
• Adjust ProcessControl: Load ctrl PtM to ANEXT IM/EX.
LdCtrl:I/E-Pm
Mains import/export active power measured from an external transducer.
• Configure LdCtrl:I/E-Pm to selected analog input
• Configure Analog input range
• Adjust ProcessControl: I/E-Pm meas = ANALOG INPUT
PowerDerating1
Analog input for Power derating function, channel 1.
PowerDerating2
Analog input for Power derating function, channel 2.
LdCtrl:TByPwr
Input to measure water temperature for temperature by generator power control.
Warming temp
Input to measure engine temperature during warm-up procedure. See setpoints Engine params: Warming
load, Warming temp, Max warm time.
Cyl temp 1 - 32
32 inputs to measure Cylinder Temperatures. Configured cylinder temperatures are displayed on controller
measurement screens as well as average cylinder temperature. Cylinder temperature protection is based on
the difference against average temperature.
RPM pick-up
Logical Analog input for RPM receiving from various types of Engine Control Units (and optionally via I-CB).
Oil press
Logical input for Oil pressure protection.
Oil pressure is calculated into “running engine” condition when configured. Engine start is blocked if Oil
pressure is higher than Starting POil setpoint setting.
LCD brightness
Analog input for external LCD brightness setting (e.g. via potentiometer). Keyboard LCD brightness setting
and binary input Alt brightness do not work when input is configured. Expected value is in the range 0 to
100%.
Hint:
Input available in IG-NT/EE and modifications only and valid only for the built-in display. For attached IG-
Display module, this input has no meaning. Input is not present in IS-NT.
