Power Module diagnostics can be examined from three platforms : from the Flash
Codes signalled with the System Status LED on the DX Remote; from the DX
Power Module Status LED; and from the Wizard which can provide more detailed
information about the fault.
)ODVK&RGHV
Any fault condition on the DX system will cause the DX Remote’s System Status
LED to flash. Any fault condition relating to the DX Power Module will cause the
DX Power Module’s Status LED to flash. Flashing occurs in bursts of flashes
separated by a two second pause. The number of flashes in each burst is referred
to as the Flash Code and indicates the nature of the fault. The title of the Flash
Code fault, as shown by the DX Remote System Status LED, is also displayed by
the HHP if connected to the faulty wheelchair.
Faults that affect the safety of the chair will cause the chair to stop while less
critical ones will be indicated but allow the chair to continue driving. Some faults
will automatically clear when the fault condition is removed, in which case the
System Status LED will become steady and the wheelchair may be driven normally.
Other faults are latched and must be cleared by turning the DX System off, waiting
for five seconds, then turning it back on again.
