High Battery Voltage - Sunrise Medical Quickie S-11 Service Manual

Understanding VSI Controller Diagnostics Codes (cont.)
3.8 Nine Bars - Solenoid Brake Trip (cont.)
Test Motor Connections
If either or both readings are incorrect, then measure the
resistance on the two small contacts on the 4-pin motor
connector see (figure A3.8.3). If both motor connectors
read approximately 60 ohms, then replace the main har-
ness. Otherwise, replace the motor that does not read
approximately 60 ohms.
If both motor connectors read approximately 60 ohms, then replace the main harness. Otherwise, replace
the motor that does not read approximately 60 ohms.
3.9 Ten Bars - High Battery Voltage
An excessive voltage has been applied to the control
system. This is usually caused by a poor battery connec-
tion. Check the battery connections.
Battery Fault
Check that the batteries are fully charged, the correct volt-
age and in good condition. Take a voltage reading from
pin 1 and pin 2 of the charger port of the VSI controller, see
(figure A3.9.1) If the meter reads more than 30 volts, then
check the charger. Otherwise, replace your controller.
If the meter reads more than 30 volts replace the charger,
If the Batteries, connections, and voltage level are correct replace the controller.
