14. Controller Errors and Diagnostic Guide
Powerchairs have a self-diagnosis feature which is programmed into
the joystick controllers. This enables most errors to be quickly
identified and corrected (see chapter 13).
Should you find that the controller does not show any error, you
have to establish at what point power ceases.
•
Check battery voltages with a multimeter.
•
Check the battery terminal connections and fuses on the
battery leads.
•
Check the circuit breaker has not ‘popped’.
•
Check loom connections – especially where the joystick
controller connects to the main loom. When disassembling
people will sometimes pull the cable to disconnect the
controller instead of pulling the plug, which can lead to
damaged connections.
•
Check voltage at charge socket. (see battery removal)
Should all the above checks not identify a fault, it is likely that the
joystick controller is faulty. If possible test with a replacement to
confirm. Do not use joysticks from different models to affect a
permanent repair, as each joystick is programmed to the specific
model it is used on.
Roma Medical does not repair joysticks. For repair contact the
manufacturers’ customer services department directly.
