4.3 Alternator thermal overload shut down
This is triggered and switches off the generator to protect
the alternator from thermal overload If it is tripped, warning
light “°C” [fig. 2, ref. 6] comes on.
The generator can only be switched on again after a few
minutes when the temperature of the alternator windings
has returned to normal. The generator must not be started
up until the cause of the fault has been identified and
eliminated.
If one of the above safety devices
is triggered, find the cause and eliminate it, then the
“STOP” button must be pressed to reset the control
panel (otherwise the signal will remain stored) to
prevent the engine from starting up.
4.4 Short circuit and overload shut down
The generator is protected from short circuits and electri-
cal overloads. A twin-pole circuit breaker [fig. 2, ref. 7]
interrupts the power supply when a short circuit occurs or
when the power supplied exceeds the nominal value.
Before restoring the power supply by pushing up the
switch lever, disconnect the electrical equipment.
4.5 Short circuit and overload shut down for the
battery charger DC alternator.
If the battery charger DC alternator is overloaded or has
a short circuit a one-pole circuit breaker [fig. 2, ref. 9]
interrupts the power supply to the 12 volt battery charger.
Before restoring the power supply by pressing the button
on the cut-out switch [fig. 2, ref. 9] have the generator’s
starter battery checked by a qualified technician.
4.6 Short circuit shut down for the low voltage
electric system.
If the low voltage circuit short circuits a circuit breaker [fig.
2, ref. 8] will interrupt the circuit and stop the generator.
If the warning lights of the engine shut down module all go
out it will not be possible to start up the system again.
Before restoring the power supply by pressing the button
located on the cut-out switch [fig. 2, ref. 8] have a qualified
technician eliminate the cause of the short circuit.
5. MAINTENANCE
Before carrying out any work on
the generator, switch off the engine and let it cool.
Any work must be carried out only by qualified
personnel.
If it is difficult to start up the engine , the attempts
should not be continued too long without first clos-
ing the sea cock.
3.4 Stop
Press the “STOP” button on the control panel to stop the
generator [fig. 2, ref. 11].
Before stopping the generator
run it for a few minutes without connecting it to the
power supply so the engine and alternator can cool
off.
4. PREVENTATIVE SHUT DOWNS
The IS series generator has a series of safety shut downs
that protect it from incorrect use and malfunctions.
When the generator stops because a safety shut down
has been triggered the light indicating the fault that has
arisen will light up on the engine overload protection
module [fig. 2, ref. 1] of the control panel.
4.1 Low oil pressure safety device
This is triggered when engine oil pressure is insufficient.
If it is triggered, the “OIL” warning light comes on [fig. 2,
ref. 4].
It is normally sufficient to replace the amount of oil that is
missing in order to start up the unit again.
The low oil pressure shut down
does not show the level of oil in the sump. The oil
level must therefore be checked every day.
- The low oil pressure shut down
does not give an indication of the level of engine oil
in the sump. Therefore, check this level daily.
- The engine functions properly at 25º inclination. It
will operate at a maximum inclination of 30º for less
than 3 minutes, (both on the longitudinal and the
transverse axis.) If the engine is operated at a
greater inclination, the risk of insufficient
lubrication or aspiration of engine oil through the
air filter is probable.
4.2 High water temperature shut down
This is triggered and switches off the generator when the
temperature of the engine’s coolant is too high or if the raw
water circuit fails.
If it is tripped, warning light “°C” [fig. 2, ref. 5] comes on.
The generator must not be started up until the cause of the
fault has been eliminated.
