The m1 motor is defective
Short circuit in the m1 motor connections.
ON/OFF light:
flashes three
times
Defective power module output.
The m2 motor connection is faulty or loose.

The m2 parking brake connection is faulty or
ON/OFF light:
loose.
flashes 6 times
The m2 parking brake is defective.

flashes 7 times flat or bad
ON/OFF light:
The battery voltage is high, above 32 V.
flashes 8 times

ON/OFF light:
DX bus cables) or short circuit in the DX bus
flashes 9 times
system (entrances to the modules)
Remedy
This is probably a 'STALL' timeout.
Place the joystick in neutral and try again
Replace the defective fuses.
Check the connections.
Secure the connection.
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.
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.
Check the connection and secure it.
Replace this motor.
Correct the connections.
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.
Check the connection and secure it
Replace this motor.
Correct the connections.
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.
Correct the connection.
Replace the drive motor.
Correct the connection.
Replace the drive motor.
Charge the batteries or replace them.
Note:
If the voltage is low (< 12 V) the electronics will not work
properly. A number of random LEDs of the 'DX' controller
flash and the wheelchair will not function.
This usually occurs during (trickle) charging.
Frequent occurrence will result in a defective power
module. Set the charger correctly.
Check the cables and the modules and replace if
necessary.
