4. Operating modes
The sensor features 6 embedded operating modes for (1) proximity notification; using a
classic NO/NC (0-24V) switching output and (2) providing information of distance data.
Operating modes 1 to 5 output a 24V signal on the NO/NC pin according to user
programmable settings. On the field programming makes it quick and easy to set up
distance thresholds using integrated teach-in buttons (PROG and SET), allowing to
customize trigger zones and meet specific application needs.
While all operating modes support distance data communication via RS485 interface at all
times, operating mode 6 has been developed to obtain only distance values without the
use of programmable switching thresholds.
Since the sensor’s NO/NC switching output and RS485 distance data use distinct pins, both
functions can be used either to complement each other or as separate functions. For
instance, the switching output can act as a trigger for the master device, e.g.
Programmable Logic Controller (PLC), to inquire the exact distance at which the light beam
has been broken.
Please respect the sensor warm up time (at least 15 mins), before operating
mode setup and sensor operation. Using the sensor before the
recommended warm-up time may negatively impact its performance.
4.1.
Operating mode overview
Operating modes are summarized in Table 6. Operating modes from 1 to 5 - provide
detection zones with distance thresholds functionalities and switching output, and require
a setup process, before going into operation mode. Mode 6 requires no setup and offers
no switching output, and distance data sampling is started as soon as the sensor is
powered.
