Vsi Controller - Pride Mobility Jet 7 Owner's Manual

VSI Controller

The electronic controller is what you use to operate
your power chair. It takes the battery voltage and
sends it to the appropriate system. The electronic con-
troller enables you to move the power chair, as well
as monitor battery charge, electronic controller func-
tions, and the condition of your electrical system. Also,
it may be used to control some optional systems such
as power elevating seats and lights.
The VSI controller is an integral electronic controller.
All of the electronics necessary to operate the power
chair are contained in one module. See figure 25a.
The VSI consists of:
1. joystick
2. keypad (see figure 26)
3. off-board charger/programming socket
4. actuator connector
(for optional equipment)
5. controller connector
6. 3-pin charger inhibit
connector
Typically, the VSI is mounted to one of the armrests and is connected to the motors, batteries, and the onboard charger at the
electronics tray.
JOYSTICK
The joystick controls the direction and speed of your power chair. See figure 25 a.When you move the joystick from the neutral
(center) position, the electromagnetic brakes release and allow your power chair to move. The further you push the joystick
from its neutral position, the faster your power chair moves. When you release the joystick and allow it to return to the neutral
position, you engage the electromagnetic brakes. This causes your power chair to decelerate and come to a complete stop.
WARNING! If your power chair begins to move in an unexpected manner, immediately release the joystick.
Unless the joystick is damaged, this action should stop your power chair.
KEYPAD
The keypad is located in front of the joystick. It contains keys necessary to operate your Dynamo. See figure 26.
ON/OFF KEY
The on/off key turns the VSI on and off. See figure 26.
WARNING! Unless faced with an emergency situation, do not use the on/off key to stop the chair. This will
cause the power chair to stop abruptly.
WARNING! Always turn the power off when you are stationary to prevent unexpected movement.
BATTERY CONDITION METER
The battery condition meter is located in front of the joystick. See figure 26. This is a 10-segment illuminated display that
indicates that the VSI is turned on and also gives the battery status, the VSI status, and the electrical system status.
