SECTION 4 – OPTIONAL ACCESSORIES
4.1 Foot Pedal
The foot pedal operates the same as the play button. When the Time
Adjustment is set to 0:00 - pressing the foot pedal once starts the unit,
pressing a second time stops the unit. If the Time Adjustment is something
other than 0:00 then pressing the foot pedal will start the unit; the unit will
run for the given time or until the pedal is pressed again.
4.2 Bin Sensor
The bin sensor is used control the AirSpeed™ SMART as it fills an overhead
bin. The bin sensor will start the AirSpeed™ SMART when no product is
detected and will stop the SMART machine when product is detected. There
are two different sensors that work with the AirSpeed™ SMART, the flat pack
Infrared (IR) sensor and the Ultrasonic
3
(US) Sensor. The bin sensor is
binary. That is, the bin is either full or empty; there is no half full, quarter
full or any other indications.
When using a bin sensor the setup up of the device controls the AirSpeed™
SMART. The timer setting should be set to 0:00 for best results. A setting
other than 0:00 will lead to erratic machine cycles.
4.2.1 Infrared Sensor
The Infrared or Flatpack sensor – is the original sensor designed to work
with the AirSpeed™ SMART. The sensor has a sensitivity adjustment for fine
tuning material detection. The yellow LED will be turn ON when there is
material present and OFF when there is no material. Position the IR sensor
over the material. Follow the instructions in Section 3 for selecting the IR
sensor. Set the timer to 0:00 and press Play. When Play is pressed, if the
bin sensor shows empty the unit starts and continues until 1) play is pressed
or 2) bin sensor shows full. When the bin sensor shows empty the unit
starts again and the cycle repeats. When the play button is pressed, if the
bin sensor shows full, the unit waits until the sensor shows empty then

At the time of writing the infrared sensor was a Carlo Gavazzi ED5506NPAP and the
ultrasonic sensor was a Pepperl & Fuchs UB1000-18GM7-75-U-V15.
