With an emergency procedure. This procedure requires immediate engine stop,
without engine cooling cycle. It applies if:
o
The key switch is turned on OFF/RESET
o
Any anomaly described as a "shutdown" is activated. In automatic mode, the
stop commands from panel (STOP button, if not disabled by bit 0 of parameter
P.0495), from serial port and from SMS are included in this category since
they activate the alarm A07 (manual stop in auto mode).
The board automatically executes the number of starting attempts configured with P.0211
parameter ("Number of starting attempts") for each battery set. At the end, if the engine is not
started, it activates A022 shutdown - "Failure to start".
Each starting attempt has the maximum duration configured with P.0210 parameter ("Duration
of the starting control"). It however ends if the condition of started engine is detected. Within
the starting procedure, HS315 automatically manages pre-lubrication, glow plugs pre-heating
and cleaning cycles.
Between a starting attempt and the next one, the board makes a pause with a duration
configured with P.0212 parameter ("Delay between two starts"). This pause may be longer
when the selected battery set is changed.
If, during a starting attempt, the board recognizes the started engine condition, it waits for the
maximum time configured with P.0217 parameter ("Maximum time for steady statuses") until
voltages and frequency of the generator are within tolerance:
•
If during the pause the engine stops, the board will go on with the next starting
attempts.
•
If generator voltages and frequency are "within tolerance", the starting procedure is
ended: from this time on, also minimum voltage and minimum frequency protections
are active.
•
If, at the end of the pause, voltages or frequency are not "within tolerance", the board
activates A008 shutdown "no steady status".
If the low speed cycle is required, the previous pause will be performed after it is finished.
At the end of the automatic starting procedure, the board manages a further delay that allows
the generator to stabilize/warm up before being connected to the load. This delay can be
configured with P.0218 parameter ("delay before delivery"): it does not work in MAN.
This procedure starts after the board has opened GCB switch (or at least after the board has
made an attempt to open, if it could be opened).
If during the automatic operations the board closed GCB switch, it considers that the generator
was heated by the load, and that it therefore needs to cool down before being stopped. Then
a cooling cycle is performed. It simply consists in keeping the engine started without load for
the time set with P.0215 parameter ("Duration of the cooling cycle"). The cooling cycle can be
aborted before the time set with P.0215 if the coolant temperature becomes lower than the
threshold set with P.0271 parameter (if this threshold is different from zero).
The emergency stop procedure consists in stopping the engine without performing the cooling
cycle. This procedure is common also in the standard stop, after the cooling cycle.
During the stopping cycle, the board removes ECU_ENABLE and FUEL controls (the second
with P.0234 seconds of delay) and activates the STOP control for P.0213 seconds. The board
waits until the engine stops. The maximum duration of the shutdown cycle is configurable with
