FunctionElectronicBoardSpecications
The function electronic board performs the following:
a. BRUSH MOTOR PROTECTION: By reading the voltage drop across (F1) fuse, the main brush
motor amperage (M1) is monitored. If the voltage drop is higher than 40 mV, the 3 LEDs on the LED
electronic board (EB2) start ashing simultaneously. If this condition persists, after a time inversely
proportional to the value of voltage drop detected, the brush motor is stopped. To reset the protection,
the electronic board must be turned off and on with the switches (SW1) and (SW2).
b. BATTERY PROTECTION: Battery charge status is shown by the 3 LEDs on the LED electronic
board (EB2), depending on the type of battery (WET/GEL) according to the following diagram:
WET GEL
Green LED on (xed) V>21.0 V>22.3
Yellow LED on (xed) 21.0>V>20.3 22.3>V>21.6
Red LED ashing V>20.3 V>21.6
When the red LED starts ashing, brush and vacuum system functions are automatically deactivated.
c. PROCEDURE FOR BATTERY SETTING (WET/GEL): on the electronic board there is a dip-switch
with 2 positions, marked as “WET” and “GEL”.
