Understanding VR2 Controller Diagnostics Codes (cont.)
3.9 Nine Bars - Solenoid Brake Trip
The parking brakes have a bad connection. Check the
parking break and motor connections. Make sure the con-
trol system connections are secure. Measure the two small
contacts on the four-pin motor connector (fig 3.8.1). If both
motor connectors read approximately 60 ohms, then re-
place the controller. Otherwise replace the motor that does
not read approximately 60 ohms.
If both motor connectors read approximately 60 ohms, then replace the controller. Otherwise, replace the
motor that does not read approximately 60 ohms.
3.10 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 VR2 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.
3.11 Seven Bars + Speed Profile Indicator Communication Error
Inspect wiring between joystick module and controller. Replace the jumper or joystick module with damaged wiring. If the
problem persists replace the controller.
