Other Features 5-45
Test Aim of Acoustic Sensor Beam
1. Move wheelchair and passenger slowly
towards doorway. TWS should detect
wheelchair and passenger (LED will flash,
buzzer will sound and the module red light
will flash) when centerline of front wheels is
between 18 and 24 inches from doorway.
2. Open vehicle access door above lift. Lower
platform to ground and place wheelchair and
passenger at rear of platform. Bridgeplate
should be up. Raise platform to floor level.
This normal platform motion with wheelchair
and passenger aboard should not actuate
TWS. If LED does flash (buzzer will also
sound and module red light will flash), turn
sensor adjustment screw slightly
counterclockwise.
NOTE
If an adjustment is made, repeat the previous
step where wheelchair is between 18 and 24
inches from doorway.
Adjust acoustic sensor timing
1. Support a flat sheet of cardboard or similar
material, directly beneath TWS module at a
distance of 4½ feet below module. Sheet
must be facing sensors.
NOTE
Before proceeding, visually inspect sensors to
verify that they are pointing directly at floor, or
nearly, and are not pointing off at an extreme
angle.
CHECKING NORMAL PLATFORM POSITION

2. Note the sensor timing access hole. This
hole provides access to a plunger-actuated
switch that sets the sensor timing. Insert a
1/16-inch diameter wire-like object into the
access hole and press the plunger inward.
The LED will flash momentarily while the
module establishes the distance and then
remain on steady. Release the plunger when
the LED ceases to flash.
NOTE
It is important that objects, such as your body,
tools, seats, etc., do not interfere with the
beam while the adjustment is being made.
