3.6 SAFETY SYSTEMS
The machine is equipped with the following safety systems:
Float:
The recovery tank is equipped with a float which prevents suction in case of overfilling,
warning the operator via a sound alarm; in this case, to restart the machine the tank must be
emptied first (see section
4.7.5
WATER DRAINING
);
Solenoid valve (OPTIONAL):
The machine is equipped with a solenoid valve letting scrubbing
water out only after the brushes have been powered on, to prevent accidental leaking;
Voltage input buzzer (OPTIONAL):
The machine is equipped with an input voltage buzzer causing
the machine to go off when the battery charge goes below a certain value, preventing the battery
from going fully flat and preserving its long-term life.
3.7 SAFETY DIAGNOSTIC SIGNALLING
The scrubbing machine is equipped with a system that ensures that all the errors detected by the machine
function control electronic board are signalled by a flashing LED.
Each error can be identified by counting the number of flashes before the first long pause. Flashing stops
when the fault is corrected and in certain cases, when the machine is turned off and then on again.
The damages and faults identified by the board prevent the operation relay closure and cause its opening -
ensuring safe operating conditions.
The diagnostic LED is located on the electronic board itself, therefore, to obtain access to it the control panel
must be removed (fig. 3.7).
