TROUBLESHOOTING
Open circuit
The thermal fuses (FA), (FB), (FC) determine the open circuit. This system allows to prevent the broom circuits and motors from
being damaged under overload conditions.
If there is an open in the circuit, the possible causes are the following.
Main broom motor; the thermal fuse (FC) activates and opens the circuit.
Possible causes:
There are bulky debris or cords around the broom or between the broom and the flange (remove the broom and the debris or 1.
cords).
The broom presses too much on the floor (check the broom height). 2.
The broom motor electrical input is too high (check the electrical input). 3.
Lock. Wait at least 2 minutes after the open circuit occurs and, when the problem is solved, push the push-button of the 4.
thermal fuse (FC).
Side broom motor; the thermal fuse (FA) or (FB) activates and opens the electrical circuit.
Possible causes:
There are bulky debris or cords around the broom or between the broom and the flange (remove the broom and the debris or 1.
cords).
The broom presses too much on the floor (check the broom height). 2.
The broom motor electrical input is too high (check the electrical input). 3.
Wait at least 2 minutes after the open circuit occurs and, when the problem is solved, push the push-button of the thermal fuse
(FA) or (FB).
The main broom does not turn.
Possible causes:
The battery voltage is too low; the warning light (11) is on (charge the battery). 1.
The motor carbon brushes are worn (replace). 2.
The motor is faulty (repair or replace). 3.
The motor driving belt is inefficient or broken (adjust or replace). 4.
The microswitch on the lifting/lowering lever does not operate (replace). 5.
The wiring harness is damaged (repair). 6.
The side broom does not turn.
Possible causes:
The battery voltage is too low; the warning light (11) is on (charge the battery). 1.
The motor carbon brushes are worn (replace). 2.
The motor is faulty (repair or replace). 3.
The microswitch (allowing the lowered side broom to turn) on the lifting/lowering lever does not operate (replace). 4.
The wiring harness is damaged (repair). 5.
