DX2 Basic (without LCD screen)
Symbol flickering fast at intervals. The number of flashes per interval provides the
information below (the following actions and checks should only be carried out by authorised
individuals).
DX2 with LCD screen
The following diagnoses refer to all the electronics. The flashing code is read from the status display
on the DX2 steering and control unit. The various modules for steering, power, and lamps, have their
own light signals indicating the status of the module concerned (steady light = OK; flashing light =
defective).
This fault analysis aids problem analysis and problem solving by indicating the possible faults. If faults
arise which cannot be identified and remedied with the aid of this analysis, kindly contact the
manufacturer. We wish to point out that in any case of improper handling or if the delivered
configuration has been changed, we cannot guarantee the accuracy of the fault indications.
DX2: The status display shows the workshop ID with the code number.

module, CLAM module).
A module connected to

Right motor (or its

or neutral active.
Right parking brake (or

1. Check whether the battery plug is inserted fully and correctly
connected to the socket of the steering unit.
2. Check whether the two batteries are connected correctly.
3. Check whether the batteries are charged.
4. Check whether the thermal fuse is defective or loose.
1. If the control unit's module LED flashes, the control unit should be
replaced.
2. If the power module diode flashes, this module must be replaced.
3. If the lamp module diode flashes, this module must be replaced.
L
If the steering and control unit has to be replaced, a new error
code might be indicated, since a complete fault analysis could
not be carried out.
Check the condition of the connected module.
1. Check whether the plugs of both motors have been inserted properly.
2. Check the plug contacts of both motors for corrosion or damage.
3. Check both motors. Unplug the motors and measure the plug
connection with an Ohm meter. If you obtain readings of more than 1
Ohm or less than 100 milliOhms, the motor is defective.
4. Check the resistance of the motor. Measure every contact using an
Ohm meter.
L
A Fault is also indicated if the motors are disconnected.
Connect again and restart the system.
As described above.
1. Check whether the motors' plugs have been inserted properly.
2. Check the plugs for corrosion or damage.
3. Check the parking brakes. Measure the resistance of the connections
by means of an Ohm meter. If the resistance value is above 100
Ohms or beneath 20 Ohms, the parking brake is probably defective.
As described above.
1. Check that the charger provided is properly connected.
2. Check whether the battery charger indicates "Charging".
3. Check whether the batteries are really being charged (deep
discharge)
4. Check whether the so-called "memory effect" has resulted in the
battery no longer being able to generated the capacity to enable the
control elements to work properly.
