FUNCTION BOARD ALARMS
Cause
Brush ammeter protection
Vacuum ammeter protection
Powerstage damaged
Overcurrent on brush or vacuum outputs
Thermal protection on brush/vacuum
stage
Fault on brush actuator limit switch rea-
ding
Brush actuator:
fi nal position not reached
Squeegee actuator:
fi nal position not reached
Internal memory reading error
Wrong key sequence.
General remote control switch damaged
or vacuum motor disconnected
Overvoltage.
Battery not connected to the function
board
No dashboard-functions communication
No traction-functions communication
INVERTER TRACTION
Description and Solution
Check the brush function mode of use. High brush motor working current
detected.
Check the absorption of the vacuum motor. High brush motor working cur-
rent detected.
Brush or vacuum powerstage damaged: replace board.
Overcurrent detected on brush or vacuum motor output:
Check motor connections and status.
Brush and vacuum powerstage overheating:
check absorptions.
Fault in the limit switch confi guration. Check brush actuator limit switch
connections and status.
Position of brush actuator not reached in the maximum time allowed. Check
actuator connections and/or for any mechanical obstructions.
Squeegee actuator position not reached in the maximum time allowed.
Check actuator connections and/or for any mechanical obstructions.
Replace board.
Rebound detected on the key signal:
Check connections and key contact status.
The general remote control switch seems damaged: check the connections
and operation of the vacuum motor; check the fuse for the power electric
board and make sure that the remote control switch operates correctly. Re-
place the remote control switch if damaged.
Overvoltage detected on the function board.
Check battery connections.
Check the traction function mode of use. High traction motor working cur-
rent detected.
Check connections between keyboard and functions.
Check connections between traction board and functions.
