ALARMS ON THE DISPLAY
Acc / Man : Accelerator / Man
The traction lever has been pushed during machine turning ON by the key. Traction can
be engaged only by release and pull again the handle lever.
POT : POTentiometer
The traction potentiometer is broken or badly connected.
Release and push the traction lever: If the error is still on the display, check the
potentiometer and replace.
Lim : Limitation
The MOSFET reach the current limitation . The traction is blocked, It can appear is
machine climb long ramp and traction card overload .
Hom: MOSFET thermal sensor
It appears when the thermal sensor inside the traction MOSFET being activated. Wait 10
min until the card cool down and try again.
Hot : overheating
Traction motor temperature sensor is engaged. Wait 15 minutes till the temperature
decrease and try again , or check the wiring between motor and card
MoS : MOSFET
The coil of the main contactor is damaged and the brush or traction function are
activated,
The traction MOSFET is broken or in short circuit : the traction is blocked.
The vacuum relay has a problem , replace.
Replace the traction card or check the main contactor.
Check the coil of the black traction motor relay positioned underneath the chassis.
MoF : Mosfet
The traction MOSFET is broken internally ; the traction is blocked , brush and vacuum
still works.
Replace the card.
bLt : traction blocked
The battery voltage is too low: the traction and all other functions are blocked . Charge
the batteries,
AcS : Brush command problem
The brush remote control switch is not engaged properly:
Push the brush switch and if the error is still on the display, check the remote control
connections. If the connections are ok, replace the contactor .
AcA : Vacuum motor command problem
The vacuum relay is not engaged properly:
Push the brush switch and if the error is still on the display, check the relay connections. If
the connections are ok, replace the vacuum motor relay .
AcH : Water solenoid valve problem
It appear is the fuse of solenoid valve is blown , the coil of the valve is interrupted
internally or the wiring is interrupted .
