Page: 116 / 142

Description & comments
Traction operational and OK.
Displayed briefly when the unit is swit-
ched on.
Wrong choice of calibration protocol.
The BDI has triggered a cut-out at the
programmed battery level.
Temperature of variable speed drive
higher than 75° - Let the drive cool down.
Accelerator activated when unit swit-
ched on.
Dead man's contact activated or joystick
pushed when machine switched on.
Two directions selected at the same
time.
Battery level lower than low battery
setting.
Battery level lower than low battery

Parameters set outside the range.
One or more settings have been corrupted.
A contactor coil is short-circuiting or
wrongly connected
MOSFET short-circuiting.

No action required.
Set the calibration protocol to "AUTO".
Charge the batteries.
Let the variable speed drive cool down -
Check its installation, the overall cleanli-
ness and the fan.
Release the dead man's contact - Check
the accelerator cable, personality acce-
lerator zero and max.
Release the dead man's contact and the
joystick - Check the dead man's signals
and the joystick's instructions.
Release the steering and dead man's
controls - Check the steering switch
cables.
Release the dead man's control or the
reverser - Check the battery voltage and
charge.
Release the dead man's control or the
reverser - Check the battery voltage and
charge and whether B+ is connected.
Change the defective settings.
Check all the settings.
Switch off the machine - Check whether
the coils are short-circuiting, whether the
control is connected directly to B+ and
the cabling.
Reset FS1 or the reverser to zero -
Check A, F1, F2, the B- cable and whe-
ther MOSFET is short-circuiting.
Switch off the machine- Check the BUS
CAN cable looms and connections.
Check the line contactor and the power
and control cable looms.
Contact SEVCON.
