3.2 Bleeding the fuel system
The presence of air bubbles in the fuel system is caused
by irregular functioning of the engine or the incapacity to
reach the nominal number of revolutions. Air might enter
the fuel circuit through a not perfectly tight seal (pipes,
filters, tank) or when the fuel in the tank is at minimum
level. The fuel system has been designed in such a way
as to autonomously eliminate air bubbles that have
penetrated the circuit. Automatic bleeding is obtained by
activating the fuel pump for a few minutes before starting
the engine.
The fuel pump is activated by pressing the START button
for a second.
Should the engine still function irregularly after this
operation, consult a technician for a thorough inspection
of the fuel system.
3.3 Starting
Before starting the generator, ensure that the preliminary
checks described in paragraph 3.1 have been carried out.
Start the generator by pressing the START button located
on the control panel [Fig. 4 Ref. 4] and release it only when
the generator has started, taking care not to exceed 15
sec. for each attempt and respecting an interval of at least
30 sec. All the warning lights of the engine protection
module [Fig. 4, Ref. 5] will come on for a few seconds, and
if there are no engine or generator faults, only the green
RUN light [Fig. 4 Ref. 6] will remain on to indicate that the
generator has been started and that functioning is regular.
Repeated attempts at starting with negative outcome
may cause excess accumulation of water in the
exhaust system with possible serious damage to the
engine.
If it is difficult to start the engine, do not insist for too
long without first having closed the sea intake cock
[Fig. 6 Ref. 2].
3.4 Stopping
The generator is stopped by pressing the “OFF” button on
the control panel.
Before stopping the generator it is recommended to
let it run for a few minutes without drawing electric
current, in order to allow the engine and the
alternator to cool down.
4. PROTECTIONS
The IS 8 and IS 9.5 generators are equipped with a series
of protections which safeguard them against improper
use and operating problems.
When the generator stops because a protection has
intervened, on the engine protection module [Fig. 5, Ref.
5] of the control panel the warning light relative to the fault
will come on.
4.1 Low oil pressure protection
Intervenes switching off the generator when the engine oil
pressure is insufficient. Its intervention is signalled by the
“OIL” light [Fig., 4, Ref. 7] coming on. Normally it is
sufficient to top up with the lacking quantity of oil to be
able to restart the generator.
The low oil pressure protection does not give an
indication of the level of engine oil in the sump.
Therefore, check this level daily.
The engine functions properly if it does not exceed
an inclination of maximum 30º for less than 3
minutes, 25º without time limit, both on the
longitudinal and the transverse axis. If the engine is
operated at a greater inclination, the risk is insufficient
lubrication or aspiration of engine oil through the
air filter.
4.2 High water temperature protection
Intervenes switching off the generator when the engine
coolant temperature is too high or there is no circulation
of seawater.
Its intervention is signalled by the “ºC” light [Fig. 4, Ref.
10] coming on.
Only restart the generator after the cause of the fault has
been identified and removed.
4.3 Alternator overheating protection
Intervenes switching off the generator when there is a
thermal overload on the alternator.
Its intervention is signalled by the “ºC” light [Fig. 4, Ref.
8] coming on. The generator can be restarted after a few
minutes when the temperature of the alternator windings
has returned to normal values. It is, however, recommended
to find and remove the causes of the intervention.
In the event of one of the above described
protections intervening, after ascertaining and
removing the cause of the intervention, press the
“STOP” button to reset the control panel (otherwise
the signal would remain in memory preventing the
engine from starting).
