Drainage system

The flue gas/water drainage system of the generator
must be separate from that of the main motors
The length of the tube from the
highest point of the drain duct to the muffler should
not exceed 2 metres. This is to prevent the water left
in the drainage duct returning to the motor after
filling the tank muffler, when the unit is turned off.
1 - Tank muffler.
This dampens the noise of the drainage and stops the
water flowing back towards the motor. The muffler
should be installed no less than 1 metre away from
the generator and positioned at a height as per fig. 4/
5.
2 - Silencer
This further reduces noise. It should be installed no
more than 1 metre from the sea drainage nozzle.
3 - Outboard drainage pipe.
This must be fitted in a position that is constantly
above sea level in all the vessel's possible conditions
of use.

5 FUEL CIRCUIT

The unit is fed by diesel fuel through the tubes marked
"Fuel inlet"(fig. 12 ref. 2 ) and "fuel outlet" (fig. 12 ref. 3).
This latter is used for the return of the excess fuel. There
is no need for filters in connections to the fuel tank, since
the unit already contains a fuel filter; however it is
advisable to fit a tap onto the fuel supply line downstream
of the tank and a single-acting valve (check valve) to
prevent the fuel system emptying for any reason. Use a
valve with a 50 millibar opening. (Max head 0.8 mt.)
The fuel pipes should be in hydrocarbon-resistant rubber,
of inner diameter 8 mm.
For further information, read the
engine instruction manual, supplied by the engine
manufacturer.
6 ELECTRICAL CONNECTIONS
6.1

Battery connection

To start off the unit an independent battery of 12V is
needed, capacity 70 Ah.
It should be connected to the terminal of the generator
(fig.12, rif.4) with cables of section 25 mm
of 5 metres and with cables of section 35 mm
distances, and following the sequence of operations
described below:
- First connect the positive pole (+) of the battery to the
terminal marked with the symbol (+) on the generator.
GB
- Then connect the negative pole (-) of the battery to the
terminal marked with the symbol (-) on the generator.
- Wipe the connections with special mineral grease to
protect against oxidation and corrosion.
The generator includes an electronic device to auto-
matically recharge the start-up battery, giving
15 A, at a voltage of 12 V, when fully charged.
ventilated area, away from the generator and from
any device which might produce heat or sparks.
Periodically check the state of the connections of the
terminals and the water level of the battery. If the
cables need to be disconnected, follow the instruc-
tions for connection in reverse order.
Do not invert the poles of the connecting cables since
serious damage might be caused to the generator and
the battery.
Do not connect other loads to the battery.
In order to reduce galvanic currents to a minimum, the
(-) of the battery of the electric generator should not be
connected to the (-) of the other batteries on board.
6.2
There are two remote control panels available, installable
on the bridge, which can be connected to the generator for
starting and stopping.
Both models are supplied with a 20 m electric connection
cable with a connector fitted at the end.
Fit the connector of the connection cable to the special
coupling located at the lower part of the instrument panel
casing inside the generator (Fig. 16
opposite part to the remote control panel.
6.3
This connection is made through the power terminal
board located on the alternator of the generator (Fig.
14 Ref. 1). This terminal board is accessed after
having removed the closing panel as shown in Fig.13
Ref. 1.
This range of generators may be operated at both 115V
- 50Hz / 120V - 60Hz and 230V - 50Hz / 240V -60Hz.
Hence different connections (and thus uses) are
possible according to the following configurations:
1 Parallel configuration; in this configuration there are
