Sonic Sensor LED Window

The sonic sensor includes a LED window that identifies

sensor status during Ultra Sonic Boom system opera-

tion (Fig. 18). 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.
