The controller software includes pre-programmed genset stop sequences. For the engine's stop function, you must configure these
inputs and outputs, and parameters.
Parameters that need a hardware function are not visible until the function is assigned to an input or output.
More information
See
GENSET controller alarms
for more information on how the engine stop alarms work, and how to configure them.
Controller modes
In AUTO and SEMI mode, the GENSET controller uses these inputs and outputs, and parameters to stop the genset.
INFO
When the operator stops the genset under switchboard control, the controller is not involved. These sequences do not
apply to stopping a genset under switchboard control.
Inputs and outputs
More information
See the
Installation Instructions
for the default hardware for the GENSET controller.
The table below describes optional outputs for the engine stop function.
Assign the engine stop inputs under
Configure > Input/output
. Select the hardware module, then select the input to configure.

Digital input
Pulse
Optional. When the controller is in SEMI mode, the operator or
another system can activate this input to request the controller to stop
the engine.
Engine > Command > Open
generator breaker and stop
engine
Digital input
Pulse
Optional. When the controller is in SEMI mode, the operator or
another system can activate this input to request the controller to de-
load and open the breaker, and then stop the engine.
Engine > Cooldown >
Coolant water [C]
Analogue input Units = °C
Optional. This input measures the engine water temperature, and is
used for temperature-dependent cooldown.
Parameters
Configure this parameter under
Configure > Parameters > Engine > Stop sequence > Cooldown
.
Parameter
Range
Default Comment
Cooldown time
1 s to 3 h
240 s
After the engine stop signal or command, the engine runs for this period before the
controller activates the
Stop coil
(or deactivates the
Run coil
).
Temperature
threshold
0 to 150 °C 0 °C
Optional. The engine cooldown stops if the engine coolant water temperature
reaches this threshold before the cooldown timer expires.
Configure these parameters under
Configure > Parameters > Engine > Stop sequence > Extended stop
.
Parameter
Range
Default Comment
Stop coil activated 1 s to 3 min 5 s
The
Stop coil
remains activated for this period after
Running detection
is OFF. During
this period a new start attempt is not possible.
