Flash or light
code
Possible cause Fault elimination
1x - Control logic not OK
- Switch the truck off and on
again using the key switch.
- Replace the control system.
2x
- The controller was actuated
while switching on
- The correct switch-on
sequence was not heeded
- Switch off the truck.
- Set the controller to the
position O.
- Switch the truck on again
and start up in the correct
order.
- Controller wiring incorrect after
controller was replaced
Check the wiring of the
controller; if necessary, correct
the wiring.
3x - Motor connection not OK
- Check the motor
connections; if necessary,
connect the motor.
- Short-circuit between motor
and housing
- Check whether a short-
circuit has occured; if
necessary, eliminate the
cause properly.
4x
- Controller potentiometer
outside tolerance.
- Replace controller.
5x
- Current sensor defective
- Control logic defective
- Replace the control system.
7x
- Excess temperature (>75 °C)
triggered with hot control
system
- Check the motor current; if
necessary, eliminate the
mechanical or electrical
overload.
- Excess temperature (>75 °C)
triggered with cold control
system (heat dissipator)
- Replace the control system.
8x - General relay coil defective - Replace the control system.
Continuous
flashing
- Battery capacity too low - Recharge the battery.
Continuously lit
- Both directions of travel have
been actuated simultaneously
- Check and, if necessary,
replace the wiring.
- Check the controller for
correct functioning; if
necessary, replace it.
