FAULT ANALYSIS

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.
Number
0 There is no indication of
the charge level of the
batteries after the
steering unit is switched
on.
1 One of the DX modules
is defective (controls,
power module, light
module, CLAM module).
2 A module connected to
the power module is
defective.
3 Left motor (or its
connection) is defective.
4 Right motor (or its
connection) is defective.
5 Left parking brake (or its
connection) is defective.
Steering unit defective

7 Battery voltage too low
Problem/Fault
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.
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.
L
If fitted with 300W Schmid motors, this fault will also display if
the motors are disconnected.
1. Unplug both motors. Switch the steering off and then on again, while
leaving the joystick in the neutral position. If this flashing sequence
appears again, the steering is defective.
2. Unplug both motors. Again switch the steering off and on while
leaving the joystick in the neutral position. Then briefly push the
joystick in any arbitrary direction. If the steering relay then clicks twice
and a fault is indicated in the left motor, the steering is in order. If any
other fault is indicated and the steering relay does not click twice, the
steering is defective.
3. Check the motors as described above in 3. and 4.
L
If a fault is shown in one motor while driving, it could be
indicated as a steering fault.
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.
