'DX' faultfinding table
Check the malfunction/signal with the aid of the following list.
Signal
Possible cause
Remedy
ON/OFF light
does not go on:
the wheelchair
does not move.
The controller plug is not properly inserted
in the 'power module'.
Insert the plug properly in the 'power module'
(DX BUS).
The DX power module is behind the cover that is
on the outside under the chair against the battery
tray.
Both fuses are defective
Replace the defective fuses.
The batteries are not properly connected.
Check the connections.
A connection of the batteries is loose.
Secure the connection.
ON/OFF light:
flashes once
DX module faulty.
Replace one or more modules. The "on/off" LED
indicates the condition of the entire system.
The modules all have a separate status LED:
in this way, you can see which one is faulty.
ON/OFF light:
flashes twice.
DX accessory faulty.
The module displays a fault as a result of a
programming fault or short circuit and/or overload
of the accessories.
The (optional) electrical high/low adjustment is
not in the lowest position. The LED flashes twice
to indicate that the speed limitation has been
switched on: the wheelchair will drive
considerably more slowly.
ON/OFF light:
flashes three
times
The left-hand motor (m1) connection is
faulty or loose
Check the connection and secure it
The left-hand motor (m1) is defective
Replace this motor.
Short circuit in the left-hand motor (m1)
connections.
Correct the connections.
Defective power module output.
Check the motor for a defect: an output of the
power module will only become defective through
a defect in the motor itself.
Only replace the power module if the fault occurs
immediately upon switching the unit on. If the
fault occurs when you are starting to drive, the
entire left-hand motor circuit is causing the fault.
In this case, replace the entire drive unit
concerned.
ON/OFF light:
flashes four
times
The right-hand motor (m2) connection is
faulty or loose.
Check the connection and secure it

power module will only become defective through
a defect in the motor itself.
Only replace the power module if the fault occurs
immediately upon switching the unit on. If the
fault occurs when you are starting to drive, the
entire left-hand motor circuit is causing the fault.
In this case, replace the entire drive unit
concerned.
