After the starter motor has disengaged, the
Safety On timer
is activated, allowing
Oil Pressure
,
High Engine Temperature
,
Under-speed
,
Charge Fail
and any
delayed Auxiliary fault inputs to stabilize without triggering the fault.
Once the engine is running, the
Warm Up timer
, if selected is initiated, allowing
the engine to stabilize before accepting the load.
If an auxiliary output has been selected to give a
load transfer
signal, this would
then activate.
NOTE: A load transfer will not be initiated until the Oil Pressure has risen. Thus
preventing excessive wear on the engine.
On removal of the Remote Start signal, the
Stop delay
timer is initiated, once it
has timed out, the
load Transfer
signal is de-energized, removing the load. The
Cooling timer
is then initiated, allowing the engine a cooling down period off load
before shutting down. Once the
Cooling timer
expires the
Fuel Solenoid
is
de-energized, bringing the generator to a stop.
4.3 MANUAL OPERATION
●HGM6120
: This manual mode is activated by pressing the
pushbutton.
This manual test mode is activated by pressing the
pushbutton. An LED
indicator beside the button confirms this action. In any of the two mode, pressing
the
pushbutton will initiate the start sequence.
If the
pre-heat
output option is selected this timer is then initiated, and the
auxiliary output selected is energized.
After the above delay the
Fuel Solenoid
is energized, then the
Starter Motor
is
engaged.
The engine is cranked for a pre-set time period. If the engine fails to fire during
this cranking attempt then the starter motor is disengaged for the pre-set rest
period. Should this sequence continue beyond the set number of attempts, the
start sequence will be terminated and
Failed to start alarm
will be displayed on
the LCD screen.
When the engine fires, the starter motor is disengaged and locked out at a pre-set
frequency from the Alternator output. Alternatively a Magnetic Pickup mounted on
the flywheel housing can be used for speed detection (This is selected by PC
using the 6100 series configuration software, or form from the front panel). Rising
oil pressure can also be used to disconnect the starter motor.
