TEST
The gen-set will be started when the controller is put to TEST mode and will remain running unloaded. If a mains
failure occurs, the MCB will be opened and after Transfer Delay (page 201) the GCB will be closed and the gen-
set will supply the load. After the mains have recovered, the delay Mains Return Delay (page 200)l will count
down and if it elapses and the mains is still ok, the controller will transfer the load back to the mains after
Transfer Delay (page 201) and the gen-set will remain running unloaded again until the mode is changed.
Remote test on load
When binary input is closed, the controller automatically transfers load from the mains to the gen-set. See LBI
REM TEST ON LOAD (PAGE 312).
5.4.4 Engine start
Diesel engine
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 341) and GLOW PLUGS
(PAGE 332) are energized for time period given by the setpoints Prestart Time (page 161) and Glow Plugs Time
(page 162).
After Prestart Time (page 161) and Glow Plugs Time (page 162), the output FUEL SOLENOID (PAGE 326) is
energized and after Fuel Solenoid Lead (page 172) the starter of motor is activated by energizing the output
STARTER (PAGE 344).
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 161), or
One of Additional running engine indications (page 102) signals becomes active.
The controller remains in the Starting phase until the engine speed exceeds the value of Starting RPM (page
161), after that it is considered as started and the Idle period will follow.
The maximum duration that the output STARTER (PAGE 344) is energized is determined by the setpoint
Maximum Cranking Time (page 160). If the engine does not start within this period, the output STARTER
(PAGE 344) is de-energized and a pause with length determined by Cranking Fail Pause (page 160) will follow.
PRESTART (PAGE 341) and GLOW PLUGS (PAGE 332) 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 160).
Once the engine is started, the Idle period follows. The binary output IDLE/NOMINAL (PAGE 335) remains
inactive (as it was during the start). The idle period duration is adjusted by the setpoint Idle Time (page 172).
After the idle period has finished, the output IDLE/NOMINAL (PAGE 335) is activated and the start-up
sequence is finished. The Stabilization (page 81) phase follows.
