Meaning of the LED indicaons
The LED indicaon light on top of the joysck has two main funcons. First, it is used when
adjusng the minimum and maximum currents and ramps (see pages 29 and 31).
Secondly, it is informing the user about malfuncons of the joysck. Beneath you nd the
meaning of the LED indicaons:
Overload (7 flashes)
In case of an overload situation, the joystick is automatically switched off. The LED light
will flash seven times in a row, pause and flash seven times again. The joystick will start to
work normally again when the power is switched off and on. Make sure that the problem
is fixed before turning on the power (the reason can be a cable injury or short circuit).
Error signals from the potentiometers (1 or 2 flashes)
If the LED light ashes once, pauses and ashes once again (reapetedly), there is a
problem with the forward-backward potenometer. Please contact service/producer. The
life length of the potenometer is approx. 5-10 years.
If the LED light flashes two times, pauses and flashes two times again (repeatedly) there is
a problem with the left-right potentiometer. Please contact service/producer. The life
length of the potentiometer is approx. 5-10 years.
PCB broken (constant flashing without pauses)
If the LED light ashes constantly without pauses, it indicates that the PCB (printed circuit
board) is broken because of a high voltage spike. The PCB must be replaced. In this case
the warranty is not valid. Please contact the service/producer.
