Operation of the generating set
During operation
Regularly check the indicators on the generating set in-
strument panel.
Notice:
If the generating set runs continuously, the oil
level should be checked every 8 hours.
Never press the START button when the generating set
is under operation.
Alarm indicators
If the oil pressure is too low in the engine lubrication cir-
cuit, the “engine oil pressure” indicator illuminates and
an audible alarm sounds and the generating set stops.
If the coolant temperature is too high, the “coolant tem-
perature” indicator illuminates and an audible alarm
sounds and the generating set stops.
I
Warning! :
Never open the coolant and oil circuit
caps when the engine is running and/or hot.
If the voltage supplied by the engine alternator drops,
the “Battery charge” indicator illuminates.
See the “Fault-finding” section for the basic checks to
make in the event of a fault.
In all cases, if one or more of these problems persist,
stop your generating set except in emergencies and
contact your Nanni Diesel authorised dealer.
Stopping the generating set
Before stopping the generating set, cut the power
of the electrical appliances connected to the craft’s
on-board electrical circuit.
Depress the ON/STOP button and then release.
Emergency stop
You can stop the engine manually if the standard shut-
down procedure is not working or in an emergency. Use
the emergency stop button situated on the electrical
junction box or cut the fuel supply.
I
Warning! :
Working on a running motor is extremely
dangerous.
After the engine has stopped
Open the circuit breaker (battery supply closed), close
the seacock (if fitted) and the fuel shutoff valve. Check
the condition of the compartment in order to identify any
leaks.
I
Warning! :
Even after your generating set has
stopped, elements remain hot and pressurised for sev-
eral minutes. As far as possible, limit work on the gen-
erating set immediately after stopping it.
I
Caution! : If your generating set is connected to
a seawater intake,
if the craft is being towed, stop the
generating set and always close the seacock to prevent
the generating set from accidentally filling with seawa-
ter.
