Possible Joystick Trip; Possible Control System Trip; Solenoid Brake Trip - Sunrise Medical Quickie S-11 Service Manual

Understanding VSI Controller Diagnostics Codes (cont.)
3.6 Seven Bars - Possible Joystick Trip
A joystick trip is indicated. Make sure that the joystick is in the center position before switching on the control system.
Check that the batteries are fully charged and in good condition, examine the joystick for damage. This fault can be
caused by a joystick that fails to center itself due to being dirty, bent or broken. If this is the case, replace the controller.
If the joystick fails to center because it is bent or broken, replace the controller
3.7 Eight Bars - Possible Control System Trip
A control system trip is indicated. Make sure that all connections are secure.
Controller Fault
Check that the batteries are fully charged and in good condition, and check all joystick connections and cables. If this
does not correct the problem, then replace the controller.
3.8 Nine Bars - Solenoid Brake Trip
Brake Fault
The parking brakes have a bad connection. Check the
parking brake and motor connections. Make sure the con-
trol system connections are secure.
Brake Fault
Check battery connections and cables. Set the meter to
ohms and measure the resistances from pin 9 to pin 7 of
the 9-pin beau plug see (figure A3.8.1.) Measure the resis-
tance from pin 9 to pin 8 of the 9 pin Beau connector see
(figure A3.8.2).If both readings are approximately 30 ohms,
replace the controller.
If both readings are approximately 30 ohms then replace the controller
