4.2.1.2 Starting sequence
NOTE: There is no start delay in this mode of
operation.
1. The fuel relay is energized and the engine is
cranked.
NOTE: If the unit has been configured for CAN,
compatible ECUs will receive the start
command via CAN.
2. If the engine fails to fire during this cranking
attempt then the starter motor is disengaged for
the crank rest duration after which the next start
attempt is made.
Should this sequence continue beyond the set
number of attempts, the start sequence will be
terminated and the display shows the FAIL TO
START icon.
3. When the engine fires, the starter motor is
promptly disengaged.
Speed detection is factory configured to be
derived from the main alternator output frequency
but can additionally be measured from a magnetic
pickup mounted on the flywheel (selected by PC
using the 3000 series configuration software).
Additionally, rising oil pressure can be used to
disconnect the starter motor (but cannot detect
underspeed or overspeed).
NOTE: If the unit has been configured for CAN,
speed sensing is via CAN.
4. After the starter motor has disengaged, the ‘Safety
On’ timer activates, allowing Oil Pressure, High
Engine Temperature, Underspeed, Charge Fail
and any delayed Auxiliary fault inputs to stabilize
without triggering a fault.
4.2.1.3 Engine running
In manual mode, the load is not transferred to the
generator unless a 'loading request' is made.
A loading request can come from a number of
sources.
– Activation of an auxiliary input that has been
configured to remote start on load
– Activation of the built-in exercise scheduler if
configured for 'on load' runs.
NOTE: The load transfer signal remains inactive
until the Oil Pressure has risen. This
prevents excessive wear on the engine.
Once the load has been transferred to the generator, it
will not be automatically removed.
To manually transfer the load back to the mains
either:
– Press the AUTO mode button to return to
automatic mode. The set will observe all auto
mode start requests and stopping timers before
beginning the Auto mode stopping sequence.
– Press the STOP button.
– Deactivation of an auxiliary input that has been
configured to remote start on load.
4.2.1.4 Stopping sequence
In manual mode, the set will continue to run until
either:
– The STOP button is pressed. The set will
immediately stop
– The AUTO button is pressed. The set will observe
all auto mode start requests and stopping timers
before beginning the Auto mode stopping
sequence.
