Setting
The ultrasonic sensor has two outputs with individually adjustable limits. Output 2 is factory set
as an analog output on the RU...LIU devices and can be used either as a current output, a
voltage output or as a switching output.
The RU…2UP… devices have two switching outputs. The user can set an individual switch
point as well as a double switch point for the switching outputs. The double switch point is
used for window or hysteresis functions. The output behavior of the switching outputs and the
analog outputs is shown in the chapter Functions and operating modes [
The sensor switches automatically to normal operation after the teach-in operation is success-
fully completed. The devices can be taught with a teach adapter, via pushbuttons on the device
or by manual bridging:
