7.3.2. Relative detection (see function 10 of Tab.1 at page 14)

The digital output (PNP) switches each time a certain object passes

inside the sensitive area, independently from its position in the area

(Fig.14).

The analog output in this configuration is always active and the voltage

is proportional to the number of obscured optics (also non adjacent)

independently from the real switching of the digital output (PNP)

caused by the object detection.

Analog output PNP output Analog output PNP output

= 3V (4,5,6 channels) ON = 3V (1, 2,3 channels) ON

Analog output PNP output

= 5V ( 4, 5,6 ,7, 8 ch an nels) OFF

7.3.3. Detection tolerance (see functions 11 and 12 of Tab.1 at page 14)

The tolerance of the detected object’s measurement can be changed

by means of the the dip-switches; in detail it is possible to select

between an exact detection and detection with a tolerance channel.
