4.5 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 m. 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.
•
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 m
away
from the generator and positioned at a height as per
Fig.
3
,
4
.
•
Silencer
. This further reduces noise. It should be
installed no more than
1 m
from the sea drainage
nozzle.
•
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.
9
ref.
2
), and
"FUEL OUTLET"
,
(Fig.
9
, 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 mbar
opening,
(max head
0.8 m
).
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
12 V
is
needed, capacity
100 Ah
.
Battery capacity never must be lower than the indicated.
It should be connected to the terminal of the generator,
(Fig.
9
, ref.
4
), with cables of section
25 mm
2
up to
distances of
5 m
and with cables of section
35 mm
2
for
longer 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.
• 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
automatically recharge the start-up battery, giving
40 A
,
at a voltage of
12 V
, when fully charged.
Install the battery in a well-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 instructions 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 Remote control panel connection
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.
11
, ref.
1
), and the
opposite part to the remote control panel.
Run the remote control cable through one hole as shown
in Fig.
11
, ref.
2
.
