Likely Cause of Condition and Possible Action
10
CANH Fault
(see Limp Mode below)
Cause: 1. An invalid voltage has been detected on the
DXBUS CANH line.
2. Communication is not possible using the
CANH wire, or the CANH and CANL wires
are shorted together.
3. Hazard lights were turned on when the DX
System was turned on.
4. The CANH is used to generate a Kill signal by
any DX Module which detects an unsafe
condition, or by an external device such as an
emergency stop switch.
The CANH wire is pulled to either B or
Battery - and causes the DX System to shut
down.
Action
<
Check the continuity of the DXBUS cable.
<
Check for shorts between DXBUS pins. An
open or short circuit on another DX Module
can cause this fault.
<
If the Hazard Lights were already switched on
when the DX System was turned on, Flash
Code 10 and Limp Mode (slow driving) may
result.
To clear this fault, turn the Hazard Lights off,
then turn the DX System off then on again.
<
If generated by a Kill signal, the cause of the
fault is severe.
11
Stall Timeout Fault
Cause: The motor current has been at, or close to, current
limit for longer than the Stall Timeout parameter
value.
Action
<
Turn the DX System off then on again.
