When using the generator always
bear in mind that in wet or very humid places and in
confined conduction spaces it is obligatory to comply
with articles 313 and 318 of Presidential Decree No. 547
27/04/55, as well as Chap. 11 Section IV of the CEI 64-8
regulation.
4.2 Prescriptions for safety during installation
and setup
- The personnel in charge of installation and starting of
the generator must always wear a protective helmet,
safety shoes and overalls.
- Use protective gloves.
- Do not leave disassembled parts, tools or anything
else not forming part of the system on or near the
engine.
- Never leave inflammable liquids or cloths soaked in
inflammable liquids in proximity of the generator,
near electric equipment (including lamps) or parts of
the electrical system.
- Take the necessary precautions to prevent the danger
of electrocution.
- Check that the earthing system has been installed
and constructed in accordance with regulations.
5 USING THE GENERATOR
5.1 Preliminary checks
Before beginning with any starting procedure, it is extremely
important to become familiar with the generator and its
controls. Furthermore, a visual inspection must be carried
out on the machine and the installation.
Any source of potential or real danger must be eliminated
before proceeding.
· Identify the position of the emergency stop buttons,
switches and other emergency systems on the generator.
· Learn the special emergency procedures relative to the
installation in question.
- the oil level by means of the dipstick [Fig. 7 Ref. 2] (see
table A for recommended oils [Fig. 8]).
- that all the anchoring points of the generator are properly
tightened.
- that all the electrical utilities are off to prevent starting the
generator on load
- that the water and fuel pipes are properly connected
- that all the electrical connections have properly been
carried out and that there are no electrical connections in
a bad state.
- that the water cock is open [Fig. 6 Ref. 2]
- that the section of the water circuit from the pump to the
valves has been filled manually if a non-return valve has
been mounted on the sea intake (as recommended in the
installation manual) [Fig. 4 Ref. 1].
5.2 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.
To eliminate the air bubbles, first of all eliminate the cause
and carry out the following operations:
1 - Adjust the fuel pump lever manually [fig.7, ref.3] until
all the air in the supply system has been released.
2 - Repeat the operations described above if engine
operation is still irregular.
For more detailed information,
consult the manual supplied by the engine manufacturer
that accompanies each generator .
5.3 Starting
Before starting the generator, ensure that the preliminary
checks described in paragraph 5.1 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].
5.4 Stopping
The generator is stopped by pressing the button [Fig.4,
Ref.4] on the control panel in "STOP"position.
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.
