3.3 TEST
OPERATION
NOTE:- If a digital input configured to panel lock is active, changing module modes will not be
possible. Viewing the instruments
and event logs
i
is NOT affected by panel lock. If panel lock is
active the Panel lock indicator (if configured) illuminates.
To initiate a start sequence in
TEST
, press the
pushbutton. When the controller is in the test mode (indicated
by an LED indicator beside the button), pressing the
START
(
I
) button will initiate the start sequence.
NOTE:- There is no Start Delay in this mode of operation.
If the
pre-heat
output option is selected this timer is then initiated, and the auxiliary output selected is energised.
After the above delay the
Fuel Solenoid
(or ECU
output if configured) is energised, then one second later, the
Starter Motor
is engaged.
NOTE:- If the unit has been configured for CAN, compatible ECU’s will receive the start command
via CAN.
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
Fail to Start
will be displayed.
Alarm
Shutdown
Failed to start
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 5300 series configuration software). Rising oil pressure can also be used to disconnect
the starter motor, however it cannot be used for underspeed or overspeed detection.
NOTE:- If the unit has been configured for CAN, speed sensing is via CAN.
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 stabilise without triggering the
fault.
Once the engine is running, the
Warm Up
timer, if selected, is initiated, allowing the engine to stabilise before it
can be loaded.
The generator will continue to run
On
load regardless of the state of the mains supply or remote start input until the
Auto
mode is selected.
If Auto mode is selected, and the mains supply is healthy with the remote start on load signal not active, then the
Remote Stop Delay Timer
begins, after which, the load is disconnected. The generator will then run
off
load
allowing the engine a
cooling
down period.
Selecting
STOP (O)
removes the Close Generator output (if configured) and de-energises the
FUEL SOLENOID
,
bringing the generator to a stop.
