The VSI control panel is shown at
right. A description of each feature
follows.
On/Off switch
The ON/OFF switch turns wheel-
chair power on and off. When
wheelchair power is on, the battery
gauge illuminates.
Battery gauge
The three-color (green, yellow and
red) battery gauge illuminates when
controller power is on. The battery
gauge shows the charge level of the batteries. As the batteries discharge, the lights go off from green
to red, similarly to an automobile’s gas gauge (all lights on = full). When the batteries are nearly
discharged, only the red lights will illuminate. When the red lights flash slowly, charge batteries
immediately. When you turn the controller on, the battery gauge shows an estimate of the remain-
ing battery charge. The battery gauge gives you a more accurate reading about a minute after you
start driving the wheelchair. The battery gauge also provides a diagnostics display when wheelchair
electrical system problems occur. See TROUBLESHOOTING for a description of the battery gauge
diagnostics.
Maximum speed / profile indicator
This is a 5-segment display which indicates the maximum speed setting or which drive profile is
selected (if drive profiles have been programmed).
Horn button
This button operates the wheelchair’s horn.
Speed / profile decrease button
This button decreases the maximum speed setting (or selects a lower drive profile, if drive profiles
have been programmed).
Speed / profile increase button
This button increases the maximum speed setting (or selects a higher drive profile, if drive profiles
have been programmed).
MOtORs
The motors operate in both the forward and reverse direction. Motor speed and direction are con-
trolled by the joystick. The joystick commands are interpreted and applied to the motors by the
circuits of the integral controller.
