Inputs and Outputs
Any Binary input or output can be configured to any controller terminal Inputs are BI1 − BI6,
Outputs are BO1 − BO6) or changed to different function by LiteEdit software.
There is fixed 1 sec delay when any binary input is configured as protection.
Table 4-6 Binary Inputs
Alarm Alarm type Warning or Shut down
Alarm active All the time, or Engine running only
Rem start/stop External request for engine run. AUT mode only.
Emergency stop If the input is opened, shut down is immediately activated. Input is
inverted (normally closed).
Sprinkler If the input is closed all alarms are disabled except the binary input
EMERGENCY STOP and ”engine over speed protection”.
Access lock If input is closed, no setpoints can be adjusted from controller front
panel and gen−set mode (OFFMAN−AUT) cannot be changed.
Rem start/stop External request for engine run. AUT mode only.
Remote OFF If closed, iL is switched to OFF mode (there are four modes
OFF−MAN−AUT−TEST).
If open, controller is switched back to previous mode.
Start Binary input has the same function as Start button.
It is active in MAN mode only.
Stop Binary input has the same function as Stop.
It is active in MAN mode only.
FaultRes Binary input has the same function as Fault reset button.
HornRes Binary input has the same function as Horn reset button.
Table 4-7 Binary outputs
Starter (relay output) The closed relay energizes the starter motor.
The relay opens if:
The firing speed is reached or
Maximum time of cranking is exceeded or
Request to stop occurs
Fuel solenoid (relay output) Closed output opens the fuel solenoid and enables the engine start.
The output opens if:
Emergency stop occurs or
Cooled gen−set is stopped or
In pause between repeated starts
GCB Close/Open The output controls the generator circuit breaker.
Prestart Output is closed prior to the engine start (Prestart) and opens when
START RPM speed is reached.
During repeated crank attempts the output is closed too.
The output could be used for pre−glow, pre−heat or prelubrication.
Ready to Load Output is closed if genset is running and all electric values are in limits
no alarm is active − it is possible to close GCB or it is already closed.
The output opens during cooling state.
CommonWrnSd Output is closed if :
any warning or shutdown occurs or
the gen−set malfunctions
The output opens if:
FAULT RESET is pressed
The output closes again if a new fault occurs.
Prestart Output is closed prior to the engine start (Prestart) and opens when
START RPM speed is reached.
During repeated crank attempts the output is closed too.
The output could be used for pre−glow, pre−heat or prelubrication.
Idle/Nominal Countdown when Start speed reached. The Underspeed protection is
not evaluated during idle period. A Start fail protection occurs if the
RPM drop below 2RPM during idle.
GCB Close/Open The output controls the generator circuit breaker.
AnImIOM1..4 Wrn Output is closed if the corresponding IG−IOM or IG−PTM Analog input
warning is active.
