3 Functions and features
The unit is used as an optical distance sensor�
3.1 Application areas
•
The optical distance sensor measures distances between 0�2���10 m�
•
It has a background suppression at >10���100 m�
•
The measured value is shown in a 10-segment display�
•
Two output signals can be generated depending on the set output function�
The distance between the sensor and the background must be limited to
max� 100 m by the customer� Otherwise measured values can be ambi-
guous. → 5.1 Installation conditions
4 Modes
4.1 Hysteresis function mode
The hysteresis keeps the switching state of the output stable if the measured
value varies about the sensing range� Both outputs (OUT1 and OUT2) can be set
as hysteresis function. → 9.2.4 Hysteresis function
4.2 Window function mode
The window function enables the monitoring of a defined acceptable range� Both
outputs (OUT1 and OUT2) can be set as window function. → 9.2.6 Window
function
4.3 Analogue function mode
An analogue signal, which is proportional to the distance, can be provided at out-
put 2 (OUT2). → 9.2.11 Scaling of the measuring range (analogue output).
