Setup with the Push of a Button
Many Senix ToughSonic® sensors include a “TEACH” button. This button can be used to set parameters, like the analog output range.
Senix invented the push button method of ultrasonic sensor setup in 1990. Since then, it has been universally adopted by major sensor makers worldwide.
We retain that capability, as sometimes, an in-situ calibration is the best choice in applications where a computer is not possible or available.
See the location of the TEACH button on the model and diagram below.
Analog range shouldn’t be confused with the operating range. The analog range or window is a region within the overall operating range. Ultrasonic echoes from outside the operating range are ignored. The analog range within the operating range is the region where the output voltage or output current varies, according to measured distance.
Consider instantaneous voltage or current output as position data. In a Senix sensor with a push button, the analog range can be set using the TEACH mode.
Teaching either analog endpoint by TEACH button requires a valid target at the required distance. The analog high can be either the nearer or farther point.
The ultrasonic sensor will output a voltage or current proportional with the measured distance between analog range points.
1. Press and HOLD the push button while you count THREE BLINKS of the round LED.
2. Release the push button. The round LED will continue to flash on and off slowly, indicating the sensor is in TEACH mode.
3. To exit TEACH mode, hold the push button for 3 blinks and release.
1. Ensure the sensor status LED is green.
2. Set the sensor so a valid target is at the distance you want for the LOW output.
3. To set the ANALOG LOW output at the current distance, hold the push button and count FOUR BLINKS of the round LED, then release.
1. Ensure the sensor status LED is green.
2. Set the sensor so a valid target is at the distance you want for the HIGH output.
3. To set the ANALOG HIGH output at the current distance, hold the push button and count FIVE BLINKS of the round LED, then release.
