3.6 SAFETY SYSTEMS
La macchina è dotata dei seguenti sistema di sicurezza.
The machine is equipped with the following safety systems:
¾
Socket
(picture 4.5), the same socket used for the battery charger. In case of emergency, this
socket must be taken away from the plug by means of its handle.
The operator must be trained about safety rules. Do never restore this safety system before the
problem has been sorted out. If it is necessary ask for the technician help.
¾
Emergency button:
the machine is equipped with an emergency button under the driver’s seat. If
the operator is not aboard, the machine does not start. Moreover, the machine stops automatically if
the operator forgets to switch the machine off. In this way the operator must seats again on the
machine, switch the machine off, wait for a few seconds and start the machine again.
¾
Float:
inside
the recovery tank there is a floater that stops the suction of the machine if the tank is
too full. To start the machine again the operator has to empty the recovery tank (see §
4.5.7
.water
discharge).
¾
Solenoid valve (optional):
The machine is equipped with a solenoid valve which avoids the water
leak till the starting of the brushes.
¾
Float timer (optional):
The machine is equipped with a timer on the dirty water float which avoids, in
case of water’s fluctuation inside the recovery tank, the ignition and the stop of the vacuum motor.

SAFETY DIAGNOSTIC SIGNALING
The electronic card is equipped with a particular system which shows the machine errors through quick
flashings on the battery charger display placed on the dashboard.
The number of switched on LEDs represents one of the errors listed below:
n.°
flash
Description Solution
1
The gear command is already active on ignition: the ignition key has been
activated when the gear command was already plugged in.
It is required to release the gear command in
order to eliminate the flashing signals. Should
this not happen, it may be necessary to reset the
acceleration system.
2
Battery too unloaded or subject to tension caused by a short circuit on the
power. Indicates that the tension of the system is lower than the minimum
level required for a proper functioning.
Verify that the battery is not too unloaded and if
necessary reload the battery. Alternatively verify
whether any electrical connections are loosened.
If this doesn’t solve the problem, it may be
necessary to replace the system.
3
Not used
4
Motor not connected or wrong contact on the motor circuit. This may happen
when the motor brushes do not correctly lie on the rotor or when cables are
loosened.
Verify the connections, the functionalities and the
integrity of the motor.
5
Internal fault of the regulator or earth on the motor.
There could be a negative dispersion on the
motor circuit; alternatively, verify the regulator.
6
Potentiometer failure
Check if one or more wires to the potentiometer
are disconnected
7
Temperature of the power circuit is too high; this happens when the
temperature of the mosfet is higher than 75°C +/- 5°C, i.e. when the machine
has worked in overload conditions, e.g. on too steep slopes for too long, or in
working temperature higher than 40°C. This may also happen in case of
damage of the winding of the motor, which may lead to unusual absorption of
current.
Wait until the temperature has cooled down.
8
Motor is already working on start. Indicates that the machine is being starter
when it is (or its motor) is already working.
Stop the machine and thereafter do it again
9
Software fault of the microcontroller or hardware problem. This may happen
in case of faults to the circuits, which measure the current and the loads.
Try to stop and then restart the machine. If the
fault appears again it is required to verify the
regulator.
