4.4 Functions and operating modes
The ultrasonic sensors are provided with two switching outputs that can be set independently
of each other. Two switching outputs (RU-…-2U…) or one switching output and a freely config-
urable output (current, voltage or switching output) (RU200-…-LIU…) are available, depending
on the device variant. On devices with a freely configurable output, output 1 can be used as a
switching output, and output 2 can either be used as a switching output, current output
(4…20 mA/0…20 mA) or voltage output (0…10 V/0…5 V/1…6 V ). The start and end point of
the measuring range can be set for the outputs. The measuring range must be within the de-
tection range.
The sensors can be run in normal operation as a diffuse mode or retro-reflective sensor. The
user can set an individual switch point as well as a window or hysteresis function.
4.4.1 Setting options

RU200-CK40… RU200-CP40…

4.4.2 Diffuse mode sensor
The diffuse mode is the standard operating mode of most ultrasonic sensors The sensor detects
the required object via the echo of the ultrasonic waves. The distance to an object is determ-
ined from the time of flight. Any additional wiring or accessories are not required.
When using diffuse mode sensors, a switching point or switch window is defined. The switch
window is used for window or hysteresis functions.
Diffuse mode sensor with NC function
When used as a diffuse mode sensor with an NC function, a switching point is taught in for a
switch output. The output behaves as follows:
0
