To unlock the VSI:
1. Press the on/off key and power on the VSI. The maximum speed/profile indicator should ripple side to side.
2. Push the joystick to the full forward position until the VSI beeps.
3. Pull the joystick to the full rearward position until the VSI beeps.
4. Release the joystick. There should be a long beep.
5. The VSI is now unlocked.
NOTE: If the above procedure fails to either lock or unlock the VSI, contact an authorised Pride Provider.
Off-board Charger Socket
You may use an off-board charger to charge the Go-Chair batteries through the 3-pin socket located on the front of the
VSI. If you use an off-board charger, the charger current should not exceed 5 amps. Contact an authorised Pride Provider
for more information.
WARNING! Only authorised Pride chargers should be connected to the off-board charger socket.
See an authorised Pride Provider for more information.
Controller Connector
This connects the VSI to the travel chair’s batteries, motors, and motor brakes.
Thermal Rollback
The VSI controller is equipped with a thermal rollback circuit. This circuit monitors the temperature of the controller, which
roughly translates to motor temperature. In the event that the VSI controller becomes excessively hot (above 60°C/140°F),
motor current (amperage) is reduced. For every degree above 55°C (131°F), the motor current limit is reduced by .55 amps.
This reduces your Go-Chair’s “power,” which could also reduce your Go-Chair’s speed. Once the VSI controller reaches
70°C (158°F), the current output is reduced to zero and your Go-Chair will stop. This allows the electrical components and
motors to cool down. When the temperature returns to a safe level, your Go-Chair resumes its normal operation.
VSI Error Codes
The VSI controller is designed with the user’s safety as the prime consideration. It incorporates many sophisticated self-
test features which search for potential problems at a rate of 100 times per second. If the VSI detects a problem either in
its own circuits or in the travel chair’s electrical system, it may decide to stop the Go-Chair, depending on the severity of the
problem. The VSI is designed to maximise the user’s safety under all normal conditions. The table below identifies the
individual error codes. Error codes are displayed as a rapid flashing of the lights. If you get one of these error codes,
contact an authorised Pride Provider.
