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. Also
MCB can be closed and opened manually using the MCB button, regardless of whether the mains are present or
not. No auto start is performed.
Note: The controller provides interlock between GCB and MCB, it means it is never possible to close both CB
together.
AUTO
The controller does not respond to buttons Start , Stop , MCB ON/OFF and GCB ON/OFF . Engine
start/stop request is evaluated form Mains failure/return.
Note: When the AMF function will start the engine than the engine will be running at least for the time which is
defined in Mains Return Delay (page 255) setpoint, even if the mains would return in the meantime.
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 256) the GCB will be closed and the
gen-set will supply the load. After the mains have recovered, the delay Mains Return Delay (page 255)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 256) 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 565).
5.5.4 Engine start
Diesel engine
The setpoint Fuel Solenoid (page 205) 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 621) and GLOW PLUGS
(PAGE 609) are energized for time period given by the setpoints Prestart Time (page 207) and Glow Plugs
Time (page 208).
After Prestart Time (page 207) and Glow Plugs Time (page 208), the output FUEL SOLENOID (PAGE 602)
is energized and after Fuel Solenoid Lead (page 214) the starter of motor is activated by energizing the
output STARTER (PAGE 633).
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 207), or
One of Additional running engine indications (page 132) signals becomes active.
The controller remains in the Starting phase until the engine speed exceeds the value of Starting RPM
(page 207), after that it is considered as started and the Idle period will follow.
The maximum duration that the output STARTER (PAGE 633) is energized is determined by the setpoint
Maximum Cranking Time (page 206). If the engine does not start within this period, the output STARTER
