GAS engine
The setpoint Fuel Solenoid (page 189) has to be switched to the Gas 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 585) and GLOW PLUGS
(PAGE 579) are energized for time period given by the setpoints Prestart Time (page 191) and Glow Plugs
Time (page 192).
After Prestart Time (page 191) and Glow Plugs Time (page 192), starts countdown of Sd Ventilation
Time (page 202)
After Sd Ventilation Time (page 202), the starter of engine is activated by energizing the output STARTER
(PAGE 597).
When the engine speed exceeds 30RPM, the outputs FUEL SOLENOID (PAGE 572) and IGNITION (PAGE 582)
are energized.
When the engine speed exceeds value of Starting RPM (page 191), the starter of engine is de-energized,
the engine is considered as started and the Idle period will follow.
IMPORTANT: Additional running engine indications (page 117) signals are not evaluated during the
start of a gas engine. The Pickup must be used in any case!
The maximum duration that the output STARTER (PAGE 597) is energized is determined by the setpoint
Maximum Cranking Time (page 190). If the engine does not start within this period, outputs STARTER
(PAGE 597) and FUEL SOLENOID (PAGE 572) are de-energized and a pause with length determined by
Cranking Fail Pause (page 190) will follow. PRESTART (PAGE 585), GLOW PLUGS (PAGE 579) and IGNITION
(PAGE 582) 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 189).
Once the engine is started, the Idle period follows. The binary output IDLE/NOMINAL (PAGE 582) remains
inactive (as it was during the start). The idle period duration is adjusted by the setpoint Idle Time (page
198).
After the idle period has finished, the output IDLE/NOMINAL (PAGE 582) is activated and the start-up
sequence is finished. The Stabilization (page 94) phase follows.
