Indicators
Emitters have a green LED for dc power ON. Receivers have two LED’s, one yellow and one green.
Indications are as follows:
Green ON steady: dc power ON
Green flashing: output overloaded
Yellow flashing: sonic signal received (ash rate is proportional to received signal strength;
ash is from full to half intensity).
Construction
T-style yellow PBT polyester housing with black PBT polyester back cover. Transducer housing is
threaded M18 x 1. Mating jam nut is supplied for mounting. Acoustic face is epoxy reinforced. Circuitry
is epoxy-encapsulated.
