The generators can be supplied with the fuel automatic load
kit. The kit includes: the pump, the fuel level sensor (3 levels)
and the control board. The kit does not include the pipes for
the connection between the generator tank and the external
tank as well as any safety devices (solenoid valves) necessary
for installation.
PUMP UNIT
It is usually installed on the generator set already connected to
the tank and the control board. It consists of an electric pump
and a manual backup pump connected by a series of pipes.
Two unidirectional valves allow to realize a connection by-
pass between the two pumps.

FUEL LEVEL SENSOR (3 LEVELS)
It is installed on the generator tank and connected to the con-
trol board.
The 1st level (START) provides the signal to start the pump.
The 2nd level (STOP) provides the signal to stop the pump.
The 3rd level (OVERFLOW) provides an alarm signal and
stops the pump.
CONTROL BOARD
Usually it is placed near the pump in an easily accessible and
protected position. It allows the fuel loading
in the two possible modes of operation:
automatic and manual. The board is pro-
vided with some signaling LEDs: ON Led
(power on), PUMP RUNNING Led, START
Led (pump start), STOP Led (pump stop),
OVERFLOW ALARM Led.
OPERATION
The operating mode is selected by means of a three-position
switch Aut-0-Man.
Manual Position -
By turning the manual switch in this position the pump is star-
ted. The selector turns back to zero when releasing it. In ma-
nual mode, the pump is stopped only when reaching the 3 rd
level of the fuel sensor.
Automatic Position -
When the fuel decreases to level 1, the pump is started and
kept running until the 2 nd level is reached. In the event that
fuel is reaching the level 3 (OVERFLOW) the pump is stopped
and an alarm is generated.
Zero Position -
No function.
