9. OPERATING CHECKS
9.1 MALFUNCTIONS SELF-DIAGNOS-
TIC
The display located on the control panel (Photo M
- 9) also has the function of showing any active
alarms on the machine concerning to the control
board operation; in case of alarm will be shown the
code and a brief description of the error.
Here below is the list of error messages with the
corresponding diagnostic:
Message displayed Solution
{“01 TRACTION#BLOCKAGE”} Stops traction motor to protect from excessive current
peak. To restore, restart the machine.
{“02 MAX TRACTION#TEMPERATURE”} Stops traction to protect the motor from excessive conti-
nuous current. To restore, restart the machine after the
motor has cooled down.
{“03 BATTERY SPENT”} Stops brush, suction and traction motor due to battery
voltage insufficient. To restore, restart the machine after
the battery charging.
{“04 MAX ELECTR#TEMPERATURE”} Stops traction motor due to excessive temperature of the
electronic control board unit. To restore, restart the ma-
chine after the control board has cooled down.
{“05 BATTERY LEVEL#TOO HIGH”} Stops brush, suction and traction motor due to excessive
battery voltage. To restore, restart the machine after ha-
ving checked the battery.
{“06 ACCELERATOR#PEDAL FAULT”} Stops traction for incorrect communication with the po-
tentiometer (suspect detachment). To restore, restart the
machine after having checked the correct connection of
the potentiometer.
{“07 ERROR#TEMPERATURE”} The traction speed is reduced according to the setted
value of the parameter RID_TEMP. To restore proceed at
reduced speed until the cooling of the electronic control
board unit.
{“08 BATTERY LEVEL#VERY LOW”} Stops brush and suction motor due to battery voltage in-
sufficient. To restore, restart the machine after the battery
charging.
{“09 BATTERY LEVEL#LOW”} Stops brush motor due to battery voltage insufficient. To
restore, restart the machine after the battery charging.
{“10 TANK FULL”} Stops suction motor because the recovery water tank is
full. To restore, empty the recovery tank.
{“11 START#BLOCKAGE”} Stops traction as the accelerator pedal is pressed down
when turning on the machine or after braking, avoiding
unwanted movements of the machine. To restore, fully
release the accelerator pedal.
{“12 RECOVERY TANK#EMPTY”} Indicates that the solution water tank is empty. To restore,
it is necessary to fill the solution water tank.
{“19 SQUEEGEE#LOWERED”} In reverse gear indicates that the squeegee has remained
lowered (Essential model). To restore, lift manually the
squeegee with the control lever.
{“20 COMUNICATION#ERROR”} Interrupted communication between the control panel
keyboard and the control board. Turn off the machine
and verify the integrity of the connections and try again.
