TeeJet 844 Sprayer Control - Manual (Page 11)

Confirming Speed Sensor Installation
Magnetic Wheel Sensor:
After your wheel or proximity sensor is installed and once the 844 console is
installed and powered up, you can test the speed sensor installation. Connect the
wheel speed or proximity sensor to the sensor cable, and in turn connect the
sensor cable to the 844 console. When the connection is made, rotate the wheel
on which the magnets are installed. If using a proximity sensor, you will be
sensing metal objects and not magnets. Each time a magnet (metal object for
proximity sensor) passes the sensor a red LED (orange LED for proximity
sensor) on the back of the sensor will light. The LCD display on the console will
also indicate a speed as the sensor receives and sends electronic pulses.
Radar:
If you are using a radar speed sensor it should be connected to the speed
sensor connector on the sensor end cable. An adapter cable will be necessary
when using most radars and are available through your TeeJet 844 dealer. The
844 will automatically sense if the speed sensor is a wheel speed or proximity
type or radar type sensor during calibration. The 844 is automatically adapted to
most brands of radar speed sensors, provided that the appropriate adapter cable
is used. If using a radar sensor, the 844 will display
rAd during the calibration
procedure.
