Machine Setup’s DRIVE CUTOUT is set for "1 =CHARGER &
BOOM" and machine is above elevation
2551
25
TELESCOPE OUT PREVENTED - TIL TED & ABOVE ELEVATION
Telescope OUT is not possible while the vehicle is tilted and above
elevation AND is configured to prevent drive while tilted and
above elevation.
2552
25

tion AND is configured to prevent drive while tilted and above ele-
vation.
2553
25

is above elevation
2554
25
DRIVE PREVENTED - SPEED SENSORS FAULTY
Both Speed sensor input voltages are out of range
2555
25
FUNCTION PREVENTED - SELECTED BEFORE FSW
Function switch was selected before and during foot switch clo-
sure
2556
25
FUNCTION PREVENTED - SELECTED BEFORE EMS
Function was CLOSED at power up
321
32
LINE CONTACTOR WELDED OR MISWIRED
The capacitor bank charge did not decrease from battery supply
when line contactor was de-energized (this could be caused due
to a power wiring error)
325
32
LINE & DIRECTION CONTACTORS MISWIRED
When the line contactor was closed, traction point A went HIGH
(and the capacitor bank charge did not increase to battery supply)
- this occurs if the line contactor coil wiring is swapped with that
for a direction contactor coil
33300
33
LINE CONTACTOR COIL - OPEN CIRCUIT
The capacitor bank did not increase to battery supply when the
line contactor was CLOSED
33301
33
LINE CONT ACTOR COIL - SHORT TO GROUND
Line contactor was not energized when required, due to over cur-
rent protection
33361
33
DIRECTION CONTACTOR COIL - OPEN CIRCUIT
Traction point A is collapsing when the traction MOSFETs are
pulsed. This maybe due to an open circuit traction motor or power
wiring error
