MANUAL MODE
Starting Sequence
The starter motor is disengaged when the engine fires.
Speed detection is factory configured to be derived from
the AC alternator output frequency, but can additionally
be measured from a Magnetic Pickup mounted on the
flywheel or from the CANbus link to the engine ECU
depending on module configuration.
Additionally, rising oil pressure can be used to disconnect
the starter motor (but cannot detect underspeed or
overspeed). After the starter motor has disengaged, the
Safety On Delay
timer activates, allowing Oil Pressure,
High Engine Temperature, Under-speed, Charge Fail and
any delayed Auxiliary fault inputs to stabilise without
triggering the fault.
Engine Running
Note: The load transfer signal remains inactive until
the Oil Pressure has risen. This prevents
excessive wear on the engine.
Once the generator has been placed on load, it is not
automatically removed. To manually remove the load
either:
Manual Mode is activated by pressing the
Manual Mode
button. The
Manual Mode
icon
is displayed to indicate
Manual Mode
operations. In
Manual Mode
, the set does not
start automatically. To begin the starting
sequence, press the Start button.
The fuel relay is energised and the engine is
cranked. If the engine fails to fire during this
cranking attempt then the starter motor is
disengaged for the
Crank Rest Timer
duration
after which the next start attempt is made.
Should this sequence continue beyond the
set
Number Of Attempts
, the start sequence
is terminated and the display shows
Fail to
Start
.
Once the engine is running and all starting
timers have expired, the animated
Engine
Running
icon is displayed.
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.
•
Press the
Transfer to Generator
button.
•
Activation of the inbuilt exercise scheduler
if configured for 'on load' runs.
•
Press the
Open Generator
button.
•
Press the
Auto Mode
button to return to
automatic mode. The set observes all
Auto Mode
start requests and stopping
timers before beginning the
Auto Mode
Stopping Sequence
.
•
Press the
Stop/Reset Mode
button to
remove load and stop the generator.
•
Activation of an auxiliary input that has
been configured to Generator Load
Inhibit.
In Manual Mode the set does not continue to
run until either:
•
The
Stop/Reset Mode
button is pressed -
The delayed load outputs are de-activated
immediately and the set immediately
stops.
•
The
Auto Mode
button is pressed. The set
observes all
Auto Mode
start requests and
stopping timers before beginning the
Auto
Mode Stopping Sequence
.
