Common troubleshooting
The next section covers typical problems that can be easily fixed at home and are related to the
settings or the powering up of the wheelchair. Please contact your service agent if you have any doubt.
Centre Joystick - The most common cause of this trip is if the joystick is deflected away from centre
before and during the time the control system is switched on. The joystick displaced screen will be
displayed for 5 seconds, if the joystick is not released within that time then a trip is registered.
Ensure that the joystick is centred and power-up the control system. This is best done by
ensuring there is no hand contact with the joystick knob during power-up
Low Battery - This occurs when the control system detects that the battery voltage has fallen below
16V.
Check the condition of the batteries and the connections to the control system.
High Battery Voltage - This occurs when the control system detects that the battery voltage has risen
above 35V. The most common reasons for this are overcharging of the battery or bad connections
between the control system and the batteries.
Check the condition of the batteries and the connections to the control system.
Brake Error - This occurs when the control system detects a problem in the solenoid brakes or the
connections to them.
Check the solenoid brakes, cables and connections to the control system
Check the motor brakes are not dis-engaged (see section 5)
Motor Error - This occurs when the control system detects that a motor has become disconnected.
Check the motors, cables and connections to the control system.
Inhibit Active - This occurs when any of the Inhibit inputs are active and in a latched state.
Cycle the power. This will drop out of Latched Mode that might clear the trip.
Check all wiring and switches connected to the indicated Inhibits.
Gone to Sleep - This occurs when the control system has been left inactive for a time greater than the
parameter Sleep Timer.
Charging - This occurs when the control system detects that a charger is connected to either Inhibit 1
or Inhibit 3. The Battery charging screen will be displayed during charger connection.
Disconnect the charger from the Wheelchair
Bad Cable - This occurs when the control system detects a fault in the wiring in the communication
cables between any of the modules.
Check all cables and connections for continuity and any possible pinch points
If there is any visible damage to cables, replace and cycle power. Contact your service agent
to replace.
