Damage of general relay
Overvoltage
Battery not connected to the
main card
No communication between con-
trol card and main card
Solution
Check consumption of the brush motor. Detected high current
on brush motor.
Check consumption of the vacuum motor. Detected high cur-
rent on vacuum motor.
Damage power of brush or vacuum: replace the main card.
This alarm could be shown also during the trailing of the ma-
chine.
Detect a shortcircuit on output brush motor or vacuum motor:
Check connections and motors.
on Overtemperature of brush/vacuum motor: check consump-
tion of motors.
Solution
Detected safety microswitch pressed before starting : release
the safety lever.
Overtemperature on traction : check consumption of traction
motor (IMx BT).
Replace the main card. This alarm could be shown also during
the trailing of the machine. (IMx BT)
Detected a shortcircuit on the traction motor output: Check
connections and traction motor (IMx BT).
Check how the traction function is used. Detected too high
working current on traction motor (IMx BT).
Check the condition of the electrobrake and its related mi-
croswitch.
Solution
Replace the main card.
Error on key signal: Check the key connection. Check, also,
the batteries connections and main card
Check the traction motor connections. If the connection are
OK, the general relay on the main card is damaged: replace
the main card. The same alarm is present also if power fuse is
damaged
Detected a overvoltage on the main card. Check the batteries
connections.
Check the traction motor, Detected high voltage on traction
motor (IMx BT)
Check the connections between control card and main card.
