GAS ENGINE: In this mode of operation the output closes to open the gas valve and enable the
engine to start. The output closes only if RPM > 30 (i.e. the starter motor is engaged)
with FuelSol offset.
The output opens if there is any reason to stop the engine or in pause between repeated starts.
Hint:
In the case of gas engine, the underspeed protection cannot be blocked by the Sprinkler function.
For gas engines, it is strongly recommended to use the pick-up sensor, as non-zero RPM detection is
required during the start procedure.
FuelSol offset [ s ]
This setpoint adjusts the Fuel solenoid output activation in relation to Starter output. Positive values mean
that fuel valve is opened after the Starter, negative values mean that it is open before. Negative values are
suppressed if Fuel solenoid = GAS ENGINE.
Step: 0,1 s
Range: -5,0 – 5,0 s
D+ function [ DISABLED / CHRGFAIL / ENABLED ]
DISABLED: The D+ terminal is not used.
CHRGFAIL:The D+ terminal is used for charge fail detection only.
ENABLED:
The D+ terminal is used for both functions - “running engine” detection and charge fail detection.
Hint:
The magnetization current is provided independently on this setpoint value.
Bin selector 1-4 [ OFF / ON ] (FV)
These setpoints are linked with binary outputs Bin selector X. Activity of these outputs depends on setpoint
state:
OFF: The corresponding binary output is not active.
ON: The corresponding binary output is active.
The setpoints are intended for ECU control, e.g. nominal speed switching. The binary output values can be
transmitted to ECU and control particular functions.
Force value possibility: Yes
Engine protect
Horn timeout [ s ] (FV)
The maximum amount of time the Binary output Horn is closed (horn, buzzer will sound). OFF = the output
won’t be activated, NO TIMEOUT = the output stays closed until the alarm has been reset.
Step: 1s
Range: OFF, 1 – 3600 s, NO TIMEOUT
Force value possibility: Yes
RunOnlyBlkDel1 [ s ]
Delay for Engine running Alarms activation – group 1 – see drawing below.
Step: 0,1s
Range: 0,0 – 3000,0 s
RunOnlyBlkDel2 [ s ]
Delay for Engine running Alarms activation – group 2.
Step: 0,1s
Range: 0,0 – 3000,0 s
RunOnlyBlkDel3 [ s ] (FV)
Delay for Engine running Alarms activation – group 3.
