AND INDICATORS (FIGURE 4)
DRIVE 1/DRIVE 2/OFF SWITCH -
Three (3) position toggle is located at the back of
the joystick housing. This switch allows the operator to select the type of operation or
performance which best suits a particular control need or situation. The DRIVE 1 program
uses performance values which are independent of those used for the DRIVE 2 program. As
an example, an operator may have a control need for spasticity in the morning and a very
different need in the afternoon. DRIVE 1 can be programmed for higher speeds and quicker
response while DRIVE 2 can be programmed for slower speeds and less responsiveness or
vise versa.
To select DRIVE 1 mode, move the toggle UP.
To select DRIVE 2 mode, move the toggle to the MIDDLE position.
SPEED CONTROL -
Rotary knob is located at the back of the joystick housing. Turning
the knob clockwise increases the maximum speed of the chair.
JOYSTICK -
Control Knob,
located on the top of the control,
provides proportional drive control
of speed and direction.
MODE(ON/OFF) SWITCH
-
Push button switch located at the
front of the joystick. When an
optional actuator control [Single
Actuator control, (SAC), Two
Actuator Control (TAC), Tilt and
Recline Control Module (TRCM)] is
present pushing the switch will
change the controller mode to
control the chairs actuators through
the joystick. The mode switch LED
indicator will be ON. Push the
switch again to return to normal joystick driving. The mode switch LED indicator will be off.
BATTERY GAUGE DISPLAY (BGD) -
Located at the rear of the joystick housing, it
provides information on the remaining charge in the batteries. At full charge all six (6)
segments of the bar graph are lighted; as the battery becomes discharged the farthest right
segment will go out until only the red bar is lighted; at this level the last red bar will start to
flash on and off to indicate that the user should charge the batteries as soon as possible.
The BGD also serves as a system diagnostic device when a fault is detected by the control
module. A specific number of flashes of the last two red bars (up to eight (8) flashes) will
start to flash on and off to indicate the type of fault detected separated by a pause. A chart of
the diagnostic indications is given in the DIAGNOSTIC CODE Section of the electronics
manual, part number 1114808.
