Sonic Sensor LED Window
The sonic sensor includes a LED window that identifies
sensor status during sprayer operation during operation
of the Ultra Sonic Boom system (Fig. 24). To view the
LED window, carefully remove cover from sonic sensor.
The LED window includes four (4) LED's.
During normal operation, the green LED and both yellow
LED's should be illuminated. The red LED will be off.
If there is some interference with normal sensor opera-
tion, the red LED will be flashing. The green LED will be
off. The yellow LED's may flash, be illuminated or be off.
If the sensor programming plug is removed or is faulty,
the red LED will be illuminated. The green LED will be
off. The yellow LED's may flash, be illuminated or be off.
The status of the LED's on the sensors can be used to
identify a faulty or unplugged programming plug. The
LED's also can be used to identify the presence of inter-
ference that can affect Ultra Sonic Boom system opera-
tion. If the LED's do not illuminate correctly, a problem
may exist with circuit wiring to the sensor or with the sen-
sor itself.
