The unit is able to provide a digital output in order to drive the block heater resistor. The temperature
reference is the coolant temperature measured from the analog sender input.
The block heater output function may be assigned to any digital output using
Relay Definition
program
parameters.
The engine body temperature limit is adjusted using the parameter
Engine Heating Temperature
. The
same parameter is used for engine heating operation.
The relay will become active if the body temperature falls to 4 degrees below the limit set by
Engine
Heating Temperature
. It turns off when the body temperature exceeds
Engine Heating Temperature
.
The unit is able to provide a digital output function in order to drive the fuel pump motor. The fuel pump is
used in order to transfer fuel from the large capacity main tank (if exists), to the genset daily tank which is
generally integrated in the chassis and has a limited capacity.
The fuel level reference is measured through the analog fuel level sender. When the measured fuel level
falls below
Fuel Pump Low Limit
parameter, the fuel pump output function will become active. When the
fuel level reaches
Fuel Pump High Limit
parameter, the output function will become passive. Thus the
chassis fuel tank level will be always kept between
Fuel Pump Low Limit
and
Fuel Pump High Limit
parameters.
The fuel pump relay function may be assigned to any digital output using
Relay Definition
program
parameters.
The unit provides a special function for the fuel solenoid control of a gas engine.
The fuel solenoid of a gas engine is different from a diesel engine. It should be opened after the cranking
has been started and should be closed between crank cycles. The delay between the crank start and
solenoid opening is adjusted using the
Gas Solenoid Delay
program parameter.
The gas engine fuel solenoid relay function may be assigned to any digital output using
Relay Definition
program parameters.
