DX System
Likely Cause of Condition and Probable Action
Status LED
Flash Code
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.
Cause: Motor(s) are faulty. Wheel(s) may be rubbing on frame.
Action • Ensure wheels turn freely while under no load. Have motor(s) checked
by a service technician.
12
Module Mismatch
Cause: There is a compatibility problem between DX Modules in the System.
The wheelchair will be disabled.
Action • Consult your PaceSaver Service Center.
Cause: The data held by the joystick module for another DX Module is corrupt
or incompatible with that module.
Action • Reprogramming the wheelchair system may correct this problem.
Limp Mode
If the DX System detects some faults, it will revert to Limp Mode. This is a reduced speed mode which recog-
nizes problems, but allows the wheelchair user to limp home, where the problem can be assessed.
Warning: If the DX System is displaying a fault and the chair enters Limp Mode, do not operate except to reach a
safe environment. Proceed with caution as the chair performance may be significantly altered. Have the chair
serviced by an authorized service center.
