load. If operator wants to stop the engine in test mode panel must be returned to automatic or 
manual mode. In manual mode you can stop the engine by stop button. 

Manual  Mode:

  If  you press the manual button  genset will be switched to manual mode.  In 

manual mode all start stop and preheat operations, contactor control fulfilled by panel buttons. 

 

PANEL RUNNING PHASES 

 

1.

 

Generator is still: 

In this condition engine running signals must be absent. These are oil 

pressure,  charging  alternator  warning  lamp  signal,  generator  voltage  and  frequency.  In 
manual  mode  panel  doesn’t  react  to  this  signal  but  in  automatic  mode  panel  will  try  to 
stop engine.  If  electricity  panel of genset has manual control and these  are wanted to be 
used. Electronic panel must be switched to manual mode.

 

 
2.

 

Preheating: 

In cold weathers preheating of engine can be necessary. Engine must be still 

during preheating. If parameter “preheating time” is not zero, preheating is accomplished 
before starting process by panel.

 

  
3.

 

Cranking: 

In this stage engine is cranking. All engine signals must be absent and engine 

must be still before cranking. If one of the engine signal is detected before cranking, panel 
switch to start and stop alarm. Panel will show which signal is detected with engine start 
stop  alarm.  If  oil  pressure  signal  is  detected  before  cranking  panel  will  wait  for  it  to 
decrease to zero. If “before cranking oil pressure delay” is elapsed and oil pressure is not 
zero  panel  will  switch  to  start  and  stop  alarm.  In  cranking  stage  all  engine  signals, 
alternator  frequency,  alternator  voltage,  charge  alternator  voltage  and  oil  pressure  is 
controlled.  If  one  of  the  signals  is  detected,  Panel  detects  engine  is  running,  crank 
disconnects  and  switch  to  engine  stabilization  time.  Generator  status  led  starts  to  blink. 
During  cranking,  “Str”  message  is  shown  in  the  display.  Oil  pressure  can  rise  before 
engine  running  so  when  oil  pressure  is  detected,  crank  disconnected  after  “crank 
disconnect oil pressure delay”. 

 

 
4.

 

Stabilization: 

After  generator  running  signals  detected  panel  waits  for  engine  signals  to 

stabilize. After engine stabilization time, all alarms are activated.

 

  
5.

 

Running: 

After stabilization time genset is in running condition. If genset in manual and 

test  modes,  alternator  contactor  time  is  waited  and  alternator  contactor  is  closed.  In 
manual mode operator can close the generator contactor by generator contactor button. In 
running mode generator status led is lit.

 

 
6.

 

Cooling: 

If a stop condition occurs by operator or mains status. Generator is switched to 

cooling period and engine is cooled during “cooling time”. During this time engine status 
led is blinking. If alternator contactor hasn’t been closed since last start cooling period is 
bypassed.  If  mains  failure  occurs  during  cooling  process  generator  is  switched  back  to 
running  mode  and  alternator  contactor  is  closed.  After  cooling  process  generator  is 
switched to stopping condition.

 

 
7.

 

Stopping: 

After cooling stage,  generator switches to stopping stage.  If fueling system is 

operating solenoid, operating solenoid is de-energized. If fueling system is stop solenoid 
solenoid  energizes  until  engine  stops.  If  one  of  the  engine  running  signals  is  detected 
stopping period doesn’t ends. Alternator frequency and voltage, charge alternator warning 
lamp signal and oil pressure must be absent. If panel detects engine signals after “fail to 
stop delay” panel will switch to start stop alarm. 

 

8.

 

Generator shutdown

:

 

Generator is stopped because of a red alarm. Generator cannot be 

started if alarm is not cleared.
