the circuit with a delay switch or a fuse with a higher
charge than the maximum absorption of the battery
charger. Comply with the polarity of the battery plug.
Disconnect the Anderson connector of the battery
wiring from the Anderson connector of the machine
wiring (Photo D - 7) (Photo F - 8) . Always hold the con-
nectors with the hands and never pull on the cables.
Photo H show connection diagram of the batteries
for B - BT machines.
• Attach the battery wiring to the battery, connect-
ing the terminals only on the poles marked with the
same symbol (red wiring "+", black wiring "-")!
A battery short-circuit may cause an explosion!
After checking that all the controls on the panel are in
position "0" or at rest, connect the battery connector
to the machine connector.
• Close the battery compartment making sure not
to crush any wires.
Photo I - 3 show the correct connection of the batter-
ies for B - BT machines.
4.1.5. CIRCUIT BOARD SETTINGS
CONFIGURATION
The machine is equipped to GEL battery circuit board
configured. If the operator whish to use e Pb-Acid bat-
tery, it is necessary to set the electronic circuit board
as follows:
Model "B" (DC 24V)
• TO ENTER THE BATTERY THRESHOLD CONFIGURA-
TION MODE:
1) Press simultaneously the push buttons "BRUSH
MOTOR SWITCH" (Photo C - 1) and "SUCTION MOTOR
SWITCH" (Photo C - 2) within 2 seconds after switching
on the machine with the key switch (Photo D - 1). The
three LED of the battery power test (Photo C - 3A, 3B,
3C ) will be ON.
2) Press "SUCTION MOTOR SWITCH" key within 5 sec-
onds from the previous action; you have now entered
in the configuration mode: the green and yellow LED
of the battery power test (Photo C - 3A, 3B ) will be ON.
• CONFIGURATION SETTINGS ARE DISPLAYED ON THE
BRUSH LED (Photo C - 1A) and on the SUCTION LED
(Photo C - 2A):
Gel:
BRUSH LED (Photo C - 1A) on.
SUCTION LED (Photo C - 2A) off.
Pb-Acid:
BRUSH LED (Photo C - 1A) off.
SUCTION LED (Photo C - 2A) off.
Li-Lithium:
BRUSH LED (Photo C - 1A) off.
SUCTION LED (Photo C - 2A) on.
• TO MODIFY CONFIGURATION SETTINGS:
Press the "BRUSH MOTOR SWITCH" (Photo C - 1)
• TO SAVE THE SETTINGS AND EXIT THE MODE:
Press the "SUCTION MOTOR SWITCH" (Photo C - 2)
Once the settings have been set, we have different
battery discharge levels with differentiated interven-
tion on the machine functions as specified in the fol-
lowing table:

• TO ENTER THE BATTERY THRESHOLD CONFIGURA-
TION MODE:
1) Press simultaneously the push buttons "REDUCE
SPEED" (Photo E - 3) and "SUCTION MOTOR SWITCH"
(Photo E - 6) within 2 seconds after switching on the
machine with the key switch (Photo F - 1). The second
LED of the speed indicator (Photo E - 3B ) will be ON.
2) Press "INCREASE SPEED" (Photo E - 4)" key within 5
seconds from the previous action; you have now en-
tered in the configuration mode.
• THE CONFIGURATION SETTINGS ARE VISIBLE ON
THE SPEED INDICATOR LED:
1) The first two LEDs (Photo E - 3A, 3B) indicate the
type of setting of the indicator intervention threshold
an both must be ON;
2) The third and fourth LEDs (Photo E - 3C, 3D) indicate
the battery type: for the PB-Acid battery only the third
LED (Photo E - 3C ) should be ON, while for the GEL
battery both should be ON (Photo E - 3C, 3D)
