4.4 Functions and operating modes
The ultrasonic sensors are provided with two switching outputs that can be set independently
of each other. The sensors can be operated as diffuse mode or retroreflective sensors during
normal operation. The user can set an individual switch point as well as a window or hysteresis
function.
When used in diffuse mode, either a single switch point or a switch window is defined. The
switch window is used for window or hysteresis functions. When used as a retroreflective
sensor, switching output 2 is switched on. A small switch window is taught in. The behavior of
switching output 1 is inverted in relation to switching output 2.
When using the hysteresis function, a switching range is taught in that is defined by two switch
points.
4.4.1 Setting options
The devices feature the following three setting options:
n
Setting by manual bridging (shorting)
n
Setting with connected teach adapter (accessories to be ordered separately)
n Setting via the pushbuttons
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
detection range
blind
zone
