4.4 Functions and operating modes
The ultrasonic sensors are provided with two switching outputs that can be set independently
of each other. 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 detection range. The sensors can be run in normal operation as a dif-
fuse mode or retroreflective sensor. The user can set an individual switching point as well as a
window or hysteresis function.
Other operating modes (opposed, multiplex, synchronization or enable mode) can be paramet-
erized via IO-Link.
4.4.1 Setting options
The devices feature the following setting options:
n
Setting by manual bridging (shorting)
n
Setting with connected teach adapter (accessories to be ordered separately)
n Setting via the pushbuttons
n
Setting via IO-Link
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
1
SP1
