With DC power applied to the sensor the Power Indicator
should be ON and a clicking sound should be heard from
the ultrasonic transducer.
If the Power Indicator is not ON check the power
connections. The board will not be damaged by a reverse
polarity connection.
If the Power Indicator is ON but the sensor is not
clicking, check the cable connections between the circuit
board and ultrasonic transducer. Look for broken or
shorted wires or loose connectors.
Common Problems
Output stuck at short distance value
1. An object is near the front of the sensor that is
being detected, possibly associated with the
mounting arrangement.
2. The sensor is "self-detecting" its own transmit
signal. Reduce the sensitivity by turning the
Sensitivity adjustment counterclockwise.
3. No target is being detected. Place a target in
front of the transducer at a known distance and
test for a reasonable voltage value.
