This parameter sets the period for which the Stop solenoid is energised to stop the engine. It
applies only where parameter P13 is set to
.
Stop Solenoid
The EAOM-19 must de-energise the Start solenoid, to disconnect the starter motor, once the
engine is running. Conversely, if the engine does not start after the pre-set start time, the unit
will turn off the starter motor and start again. Hence, the unit must be able to detect when the
engine has started. Four signals are available to provide engine running information, as
follows :
Charging generator energising coil current. This current should fall to zero once the
engine has started.
Engine speed, as selected by parameter P18
.
Alternator voltage, as selected by parameter P17
Oil pressure the oil pressure switch should open when the oil pressure is sufficient.
Any or all of these signals can be selected for use. It is advisable to select at least two of
them preferably 1 Engine speed and either 0 Charging generator or 2 Alternator voltage.
. If any of the selected signals appears, the unit
assumes that the engine has started.

Start Failure
When the EAOM-19 receives an Engine Start command, it energises the start solenoid to
drive the starter motor and energises the Fuel solenoid (if selected
Stop/Fuel Solenoid selection (P13)) to provide fuel for the engine. If the EAOM-19 detects
that the engine has started, it de-energises the starter motor. Engine started signals are
defined by parameter P15 Engine started signal
.
Parameter P16
defines the maximum period for which drive will
be applied to the starter motor. It makes a new attempt after a delay equal to twice the
defined
.
Parameter P06
defines the number of unsuccessful tries that
the EAOM-19 will make before abandoning the attempts. If all these attempts fail, EAOM-19
operations are locked out and a
indication is displayed.(
LED is
lit) The unit remains locked until the RESET (13) button has been pressed.
