Sices GC315 User Manual

154 GC315xx and GC400xx Technical Manual
The emergency procedure consists in stopping the engine without performing the cooling
cycle. Such procedure is also common to the normal stop, after, thus, the cooling cycle.
During the stop phase, the ENGINE ENABLING, GAS, START and PREHEAT are removed
and it the STOP command is activated instead. The FUEL command is removed after the
configured time with parameter P.0234 (“Delay between commands STOP and FUEL”). This
to avoid that the engine in stopping phase cause a depression in the fuel ducts, which could
cause electro-valve jam at the next opening command. The duration of this phase is
configurable with parameter P.0213 (“duration of stop pulse in excitement”. At the end, we
pass to the stop waiting phase. If during this phase all the stop requests cease and there is
at least one starting request, we pass to the stop cancelation one and only if the engine has
been diagnosed stopped.
It is not possible to interrupt an automatic stop cycle as situations can be happen where it is
difficult to restart the engine if it was not completely stopped.
During the stop waiting phase all engine commands deactivate and therefore the stop of the
engine is waited. The duration of such waiting is configurable with parameter P.0214
(“Duration of stopping cycle”), from which the configured time with P.0213 is subtracted
(“Duration of stopping command”). At the end of this phase, if the engine has not stopped, the
failure AL.021 is activated (“A021 – failed stop”) and we pass to the status of no stop. The
whole phase of stop waiting (and then also the failure A021) can be disabled anyway by
setting zero in parameter P.0214. If the engine stops, it goes back to the stop status. This
phase cannot be interrupted to perform further startings.
The cancel stop phase is only necessary to allow a short delay between the deactivation of
the eventual STOP command and the FUEL activation. This delay is of 0,2 seconds, at the
end of which we go back to the stop status, from where we will proceed immediately with the
starting if there are the conditions (and restarting from zero with the counting of the starting
attempts).
The controller records any change of the engine's status in the events log, if it is enabled with
bit 3 of the P.0441 parameter:
 EVT.1040: Engine stopped
 EVT.1041: Starting cycle
 EVT.1042: Engine running.
 EVT.1043: Cooling cycle
 EVT.1044: Stopping cycle
 EVT.1045: Idle cycle (idle speed)
The controller records any change of the start/stop requests in the events log, if it is enabled
with bit 6 of the P.0441 parameter:
 EVT.1050: Manual startup command
 EVT.1051: Manual stop command
 EVT.1052: Auto start command
 EVT.1053: Auto stop command
 EVT.1054: Command for start in TEST mode from digital input.
 EVT.1055: Command for stop in TEST mode from digital input.
 EVT.1056: Command for start in TEST mode from serial port
