Loaded
Gen-set is running at nominal speed and
is active.
Cooling
Gen-set is cooling before stop.
Stop
Stop.
Example:
Automatic or manual stop command was issued, engine is stopping.
Shutdown
Shut-down alarm activated.
Ventil
Gas engine - ventilation of unburned fuel when stop command comes during
cranking with gas
SDVentil
Gas engine - ventilation of unburned fuel after unsuccessful start attempt or after
shutdown stop.
EmergMan
Gen-set operation.
Example:
Used for bypass the controller and engine manual start.
Controller mode, where the LBI
is activated. All control
functions are stopped
Engine started conditions
Engine speed (RPM) >
or
Oil pressure >
Starting Oil Pressure (page 228)
or
Binary input
is in logical 0 or
D+ terminal active (reached
of supply voltage) for minimum 1 s or
Generator voltage > 25 % of
Nominal Voltage Ph-N (page 211)
or
Nominal Voltage Ph-Ph (page 211)
(any phase)
Note:
Any of these condition will disconnect starter of the engine, however for transition to next state RPM
needs to be higher than
Engine running conditions
Engine speed (RPM) >
or
Oil pressure >
Starting Oil Pressure (page 228)
or
Binary input
is in logical 0 or
Generator voltage > 25 % of
Nominal Voltage Ph-N (page 211)
Still engine conditions
Engine speed (RPM) <

Oil pressure <
Starting Oil Pressure (page 228)
and
Binary input
is in logical 1 and
Generator voltage < 50 V (all phases)
Note:
When the engine was running before and all above conditions are fulfilled, additional 2 s delay is
necessary to confirm "still engine".
When any engine running conditions are observed in still engine, then the
is
activated with the following delays:
