To Start The Engine Automatically; Autostart Engine Control - KIRLOSKAR DV Series O & M Manual

o The fuel output is controlled until the engine stops rotating and oil pressure decays (Oil Pressure
systems). If the Oil Pressure has not decayed by the end of the Max Fuel Time, the fuel output
is deactivated and the controller waits until the oil pressure has decayed, or for the remainder
of the Stop Time. The speed must remain at zero and the oil pressure must be below the alarm
set point for the "Stop Rest Time" before the engine is considered stopped.
o "Stop Failure" is displayed if the engine does not stop. The general alarm and "Fail to Stop"
outputs are activated
• READY. The engine has stopped and is ready to start again as required.
• IDLE UP. The engine is now running with the Idle output on (if configured). Oil Pressure, loss of
speed signal, overspeed and HIREV are monitored.
• WARM UP allows the engine to stabilise at full speed before going on load. Oil pressure, overspeed
and HIREV are monitored. The display shows "Warm Up" with a countdown time
• RUNNING. The display shows "Running". Operating parameters are scrolled onto the display. "Manual"
appears in the list indicating the engine was manually started.
To stop the engine manually
Push the button briefly. The unit will perform a stopping sequence as follows:
O
• IDLE DOWN. The engine runs at idle speed with a countdown time. Oil Pressure, loss of speed
signal, overspeed and HIREV are monitored.
• STOPPING. The display will show "Stopping" with a countdown time.
o If ETR fuel control has been selected the Fuel output will be de-energised.
o If ETS fuel control has been selected then the Fuel output will be energised for the Max Fuel
Time or until the engine stops. The Fuel Pull output will be energised for 1 second at the start
of the Stop Hold time. The stopping process will retry if the engine fails to stop the first time.
During the "ETS Rest" period the Fuel output is deactivated.
o The fuel output is controlled until the engine stops rotating and oil pressure decays (Oil Pressure
systems). If the Oil Pressure has not decayed by the end of the Max Fuel Time, the fuel output
is deactivated and the controller waits until the oil pressure has decayed, or for the remainder
of the Stop Time. The speed must remain at zero and the oil pressure must be below the alarm
set point for the "Stop Rest Time" before the engine is considered stopped.
o "Stop Failure" is displayed if the engine does not stop. The general alarm and "Fail to Stop"
outputs are activated
• READY. The engine has stopped and is ready to start again as required.

To start the engine automatically

Select manual mode by pressing the

Autostart Engine Control

If the Autostart input is activated, the unit will initiate an Autostart sequence. The sequence is similar to
the manual start and stop sequences above with the following additions.
• An adjustable Start Delay follows the Autostart input activation. This is usually configured to avoid
nuisance starting. The Display shows "Starting" with a countdown value. For long start delays, the
start time units may be set to minutes. If the autostart restores for more than the Start Restore time,
then the start sequence is aborted.
• The unit cranks the engine for the crank time or until the engine fires. If the engine does not fire after
the crank time, then the unit will repeat the crank procedure after waiting for the crank rest time. This
cycle is repeated for the "Crank Retries" and if the engine has not started after the last cycle, a "Fail
to Start" alarm is generated.
• The Start sequence now follows the manual starting sequence until the engine is running.
• During an Autostart run the LCD displays Auto in the top left of the display.
The stopping sequence is initiated by deactivation of the autostart input. The engine does not stop
immediately as there are three additional states in the Auto stopping sequence.
