11.1 proximity head array
warnIngs
The sensors used in this product will operate
•
if moisture of any substance that is electrically
conductive is present in sufficient quantities.
Electro magnetic interference from electrical power
•
lines and certain types of phones will cause the
sensors to activate.
These sensors are capacitive in nature and any
•
material that is conductive will activate them. These
sensors are electronic sensors and generate an
electronic field which can be affected by liquids and
radio frequency interference.
If the user is caught in the rain or some type of liquid
•
is spilled on the sensor pad, the chair has a great
potential to act erratically. Try to activate the stop
sensor or shut the chair down if possible.
Avoid use under high power lines and around cell
•
phones which will interfere with the electronic field
generated by the sensor.
A warning must be conveyed to the wheelchair
•
operator that the chair could come to a sudden stop
or act in an erratic manner due to liquids or radio
frequency interference (RFI).
Most electronic equipment is influenced by (RFI).
•
Caution should be exercised with regard to the
use of portable communication equipment in the
area around where the sensors are located in the
head array. If RFI causes erratic behaviour, shut
the wheelchair off immediately. Leave off while
transmission is in progress.
11.2 driving with the head array (fig 11.1)
The head array uses 3 zero touch sensors for driving,
one in each head pad.
The sensor in the centre of the headpiece controls
forward and reverse.
Sensors in the right and left headpieces are for right and
left directional motion respectively.
The fourth switch is your mode switch and it toggles the
head array between forward and reverse and between
driving the wheelchair and operating any ancillary
devices (such as powered seating or augmentative
communications systems.)
Switching modes
A variety of mode switches are available. These can be
divided into three types: internal, hardware mounted and
external.
Internal: mode in left pad or right pad
•
Hardware mounted: beam switch
•
External: fibre optic, button or mode jack 2. All mode
•
switches perform the same tasks.
Single click of the mode switch will toggle between
•
forward and reverse.
A double click of the mode switch will change the
•
operating mode of the system. e.g. standby to drive
to actuator etc.

your module or contact your Sunrise Medical authorised

11.3 proportional head control
Operation of the head control (Fig 11.2)
1. The drive is based on displacement of the headrest.
A small amount of pressure must be exerted on the
headrest to generate results.
2. Neutral position is when the headrest is not displaced.
3. When the headrest moves right or left, the chair will
move in the respective direction.
4. For forward or reverse the headrest needs to be
displaced in a backwards direction. Use of the mode
switch selects the direction of movement. This will be
displayed on the enhanced display module.
5. The greater the displacement of the headrest from the
neutral position the faster the chair will go.
For further details refer to the user manual supplied with
your module or contact your Sunrise Medical authorised
dealer.
