Diagnostics and Troubleshooting
The Pack Mule NXG vehicle has on-board diagnos-
tics that facilitate troubleshooting. When the control-
ler senses a fault, either when the vehicle is switched
on or is operation, it shows a fault code. (Figure 18).
If the Smartview Display is damaged or otherwise
inoperable, the fault code can be read directly from
the controller by counting the number of consecu-
tive LED flashes. The fault codes and LED codes are
shown in the charts on pages 17 and 18.
There are five categories of faults. Below are the
categories, the letter or letters identifying them in the
table, and the action taken by the controller when
sensing the fault.
1.
Information (I)
Information faults do not require
immediate action, although some cutback in
power may occur.
2.
Drive-inhibit (D) Neutral brakes or coasts the
traction motor to a stop. The fault prevents the
operator initiating drive, but does not inhibit
braking functions.
3.
Severe (S)
Immediate shut down of the sys-
tem.
4.
Very Severe (VS)
Immediate shut down of the
system.
5.
Return to Base (RTB)
Immediate shutdown of
the system.
