VSI Controller
The VSI Controller is a fully-programmable, integral electronic controller system that allows you to
operate your power chair. It is designed to allow the user to have complete control over chair movement
and speed.
The controller has been pre-programmed to meet a typical user’s needs. The program is set using
either a personal computer with software provided by the controller manufacturer or with a hand-held
programmer, also provided by the controller manufacturer.
WARNING! The controller program can affect speed, acceleration, deceleration, dynamic stability,
and braking. If it is programmed incorrectly or outside of the safe limits as determined by your
healthcare professional, it can create a dangerous situation. Only the power chair manufacturer,
an authorized representative of the manufacturer, or a trained service technician should program
the controller.
Precautionary Guidelines
Before operating the VSI Controller, please read the following. These guidelines are provided for your
benefit and will aid you in the safe operation of the controller system.
Turn off the power to the controller when transferring to or from your power chair.
Follow all of the procedures and heed the warnings as explained in your power chair owner’s manual.

Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown that electromagnetic and radio frequency waves can
have an adverse effect on the performance of electrically-powered mobility vehicles.
Electromagnetic and Radio Frequency Interference can come from sources such as cellular phones,
mobile two-way radios (such as walkie-talkies), radio stations, TV stations, amateur radio (HAM)
transmitters, wireless computer links, microwave signals, paging transmitters, and medium-range
mobile transceivers used by emergency vehicles. In some cases, these waves can cause unintended
movement or damage to the control system. Every electrically-powered mobility vehicle has an immunity
(or resistance) to EMI. The higher the immunity level, the greater the protection against EMI. This
product has been tested and has passed at an immunity level of 20 V/m.
WARNING! Be aware that cell phones, two-way radios, laptops, electricity generators or high power
sources and other types of radio transmitters may cause unintended movement of your electrically-
powered mobility vehicle due to EMI. Do not turn ON hand-held personal communication devices,
such as citizens band (CB) radios and cellular phones, while the powered wheelchair is turned
on. Be aware of nearby transmitters, such as radio or TV stations, and avoid coming into close
proximity to them.
WARNING! The addition of accessories or components to the electrically-powered mobility vehicle
can increase the susceptibility of the vehicle to EMI. Do not modify your power chair in any way
not authorized by Pride/Quantum.
WARNING! The electrically-powered mobility vehicle itself can disturb the performance of other
electrical devices located nearby, such as alarm systems.
NOTE: For further information on EMI/RFI, go to the Resource Center on www.pridemobility.
com. If unintended motion or brake release occurs, turn your controller off as soon as it is safe
to do so. Contact your Pride/Quantum Provider to report the incident.

2. Release the on/off key.
3. Push the joystick to the full forward position until the VSI beeps.
4. Pull the joystick to the full rearward position until the VSI beeps.
5. Release the joystick. There should be a long beep.
6. The VSI is now locked.
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 your Pride/Quantum
Provider.
Actuator Adjustment
The VSI can control optional power accessories such as a power elevating seat using the actuator keys
and the joystick.
NOTE: Actuator adjustment may vary depending on the VSI program. This section describes
basic actuator adjustment for power chairs equipped with one actuator. Contact your Pride/
Quantum Provider for more information regarding actuator adjustment for your power chair.
Follow the steps below for actuator adjustment for power chairs with one actuator:
1. Power on the controller.
2. Press either actuator key to activate actuator adjustment mode. Both actuator LEDs will be lit.
3. Give a forward or reverse command to the joystick to adjust the actuator.
4. Press either actuator key to return to the drive mode.
Sleep Mode
Your VSI controller has a sleep mode feature. Sleep mode is a built-in circuit that automatically shuts
off the main power if the joystick is not moved in any direction for a period of time predetermined by
controller program. The battery condition meter lights on the keypad indicate sleep mode by blinking
once every five seconds. To restore power and continue, push the on/off key twice.

15
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, motor current (amperage) is reduced. For every degree above normal temperature, the
motor current limit is reduced proportionally. This reduces “power,” which could also reduce power chair
speed. Once the VSI controller reaches its temperature limit, the current output is reduced to zero and
your power chair will stop. This allows the electrical components and motors to cool down. When the
temperature returns to a safe level, your power chair resumes its normal operation.
Fault 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 power chair’s electrical system, it may
decide to stop the power chair, depending on the severity of the problem. The VSI is designed to
maximize the user’s safety under all normal conditions. The table below identifies the individual fault
codes. Fault codes are displayed as a rapid flashing of the lights. If you encounter one of these fault
codes or experience any other problems with your power chair, contact a Pride/Quantum Provider.
Flashing Lights Diagnosis and Solution
1The batteries need charging or there is a bad connection to the batteries.
Check the connections to the batteries. If the connections are good, try
charging the batteries.
