and a brief description of the error.
Here below is the list of error messages with the
corresponding diagnostic:
Solution
Check usage mode of the traction function. High working
current has been detected by the traction motor.
Check usage mode of the brushes function. Detected ele-
vated work current by the brushes motor.
Check vacuum motor absorption. Detected elevated
work current by the suction motor.
Check usage mode of the traction function. High working
current has been detected by the traction motor.
Check usage mode of the brushes function. Detected ele-
vated work current by the brushes motor.
Check vacuum motor absorption. Detected elevated
work current by the suction motor.
Low voltage detected on function board (<90%).
Check batteries and batteries connections.
Low voltage detected on function board (<80%).
Check batteries and batteries connections.
Low voltage detected on function board. Check batte-
ries and batteries connections.
Overvoltage detected on function board. Check batte-
ries and batteries connections.
check brush motor/traction motor absorption
check brush motor/traction motor absorption
To empty recovery tank
Reboot scrubber drier (do not press user lever before
control board check)
Reboot scrubber drier
Check connections between the function board and da-
shboard.
Check connections and traction motor status.
Overvoltage detected on function board. Check batte-
ries and batteries connections.
