Binary outputs - list
Not Used
Output has no function.
Starter
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 comes up
Fuel Solenoid
Closed output opens the fuel solenoid and enables the engine start.
The output opens if:
EMERGENCY STOP comes or
Cooled gen-set is stopped or
in pause between repeated starts
Stop Solenoid
The closed output energizes stop solenoid to stop the engine. This output is deactivate 10s after the
still engine conditions are evaluated.
Hint:
Hint:
The engine can be started anytime, if all symptoms say the engine is steady regardless of the fact the
Stop Solenoid
can still be active (in that case it is deactivated before cranking).
Stop Pulse
Output is active for 1 second after S
top Solenoid
output activation. This signal is sent to ECU in case
of engine stop request.
Ignition
The output closes after reaching value of crank RPM, fixed 30RPM. Opens after stopping of the
engine or in pause during repeated start.
Prestart
The output closes prior to the engine start (
Prestart
) and opens when
Starting RPM
speed is reached.
During
Crank Attempts
the output is closed too.
The output could be used for pre-glow, pre-heat or prelubrication.
Cooling Pump
The output closes when gen-set starts and opens after stop of the engine.
Idle/Nominal
The
output
Idle/Nominal
closes after the timer
Idle Time
elapses. The
Idle Time
counter starts to
countdown when
Starting RPM
reached. The
Underspeed
protection is not evaluated during fixed 5
seconds period after reaching
Starting RPM
. A
Start Fail
protection occurs if the RPM drop below
2RPM during idle.
Hint:
Connect binary output
“Idle/Nominal” to speed governor to switch the speed: opened = IDLE,
closed=NOMINAL.
