Remote AUTO (page 459)
If the respective input is active the controller will change the mode to the respective position according to the
active input. If multiple inputs are active, the mode will be changed according to priorities of the inputs. The
priorities match the order in the list above. If all inputs are deactivated, the mode will return to the original
position given by the setpoint.
OFF
No start of the gen-set is possible. If the gen-set is running, the GCB will be opened and the engine will be
immediately stopped without unloading and cooling. After that the controller will stay in Not ready status and
cannot be started any way.
MAN
The engine can be started and stopped manually using the Start and Stop buttons (or external buttons
wired to the appropriate binary inputs) in MAN mode. When the engine is running, GCB can be closed.
AUTO
The controller does not respond to buttons Start , Stop and GCB ON/OFF .Engine start/stop request
is given by binary input Remote Start/Stop (page 460).
5.4.3 Engine start
Diesel engine
The setpoint Fuel Solenoid (page 164) has to be switched to the Diesel position.
After the command for start is issued (pressing Start button in MAN mode, auto start condition is fulfilled in
AUTO mode or controller is switched to TEST mode), outputs PRESTART (PAGE 506) and GLOW PLUGS
(PAGE 500) are energized for time period given by the setpoints Prestart Time (page 166) and Glow Plugs Time
(page 168).
After Prestart Time (page 166) and Glow Plugs Time (page 168), the output FUEL SOLENOID (PAGE 493) is
energized and after Fuel Solenoid Lead (page 169) the starter of motor is activated by energizing the output
STARTER (PAGE 510).
When one or more of following conditions are met, the starter output is de-energized:
The engine speed exceeds the value of Starting RPM (page 166), or
One of Additional running engine indications (page 103) signals becomes active.
The controller remains in the Starting phase until the engine speed exceeds the value of Starting RPM (page
166), after that it is considered as started and the Idle period will follow.
The maximum duration that the output STARTER (PAGE 510) is energized is determined by the setpoint
Maximum Cranking Time (page 165). If the engine does not start within this period, the output STARTER
(PAGE 510) is de-energized and a pause with length determined by Cranking Fail Pause (page 165) will follow.
PRESTART (PAGE 506) and GLOW PLUGS (PAGE 500) outputs are active during the pause. After the pause
has elapsed, the next start attempt is executed. The number of start attempts is given by the setpoint
Cranking Attempts (page 165).
Once the engine is started, the Idle period follows. The binary output IDLE/NOMINAL (PAGE 503) remains
inactive (as it was during the start). The idle period duration is adjusted by the setpoint Idle Time (page 169).
