Comments to table:
1: Errors who affects the driving safety will automatically stop the chair, while less risky errors will be
indicated on the control lights and driving can be resumed.
2: At certain errors the electronics will reset when the error has been corrected and the control light
remains lit. Other errors can be “connected” which means that the wheelchair needs to be turned off
for at least two seconds and then be turned on again to reset the error.
3: At less serious errors the electronics can be put to “ spare drive mode”. This means that the
wheelchair still can be driven but with all speed variables reduced.
Each error on the DX will be indicated by flashes on the maneuver box control light on the on/off
switch. The flashes get into groups with numbers from 1-12 with an interval of 2 seconds. Number of
(1-12) flashes shows the type of error that occurred.

1 Flashes - DX module error
This indicates that one of the DX modules are faulty and needs to be replaced. Control the control
lights on the modules. If any of these flashes it means that the module is broken.
2 Flashes - DX Accessories
This indicates that an accessory that is connected to the DX- system is faulty. (Not for wheelchairs in
standard mode).
3 Flashes - Left (M1) motor
This indicates a break or short circuit on the wire of the electronics module M1- connection to the
motor, alternatively a motor error. Control by unplugging the M1 connection and measure the resist-
ance between the outer pins (1 and 4), to determine a break or a short circuit on the wire from the
electronics module M1 connection to the motor, alternatively a motor error. Control by unplugging the
M1 connection and measure the resistance between the outer pins (1 and 4), to determine a brake or
a short circuit.
