During normal mode operation, the measured distance value is displayed on the LED-indicator
in %. Scale switches automatically and is indicated by a point on top of the digits.
If no objects are placed within the detection zone the LED-indicator shows »- - -«.
4.5.2 Ultrasonic with two switched outputs (2)
Product description:
The Ultrasonic Sensors with two switched outputs measurers the distance to an objekt, within
the detection zone contactless. Depending on the adjusted detect distance the switched
outputs are set. Light emitting diodes (three-colour LEDs) indicate the switching status. The
Ultrasonic Sensors indicate a blind zone, in which the distance cannot be measured.

Assembly instructions
Assemble the sensor at the installation location.
Plug in the connector cable to the M12x1 connector.
Start-up
Ultrasonic sensors are delivered factory made with the following settings:
Switched outputs on NC contact
Detecting distances on 750/810 mm
Note
The Ultrasonic sensor has internal temperature compensation. Because the sensor heat up on
their own, the temperature compensation reaches its optimum working point after approx. 30
minutes of operation.
During normal mode operation, a yellow LED signals that the corresponding switched output
has connected.
