4.3.
Operating mode 1 (default)
Description
This mode is used for reactive detection applications with the switching output triggered as
soon as an object enters the light beam in the trigger zone. A background threshold is
programmed to set the trigger zone. Mode 1 is useful for alarm applications, positioning
tasks and monitoring distance.
Setup
Figure 9. Mode 1 setup phases
Step 1 - Set background threshold
●
Make sure that an object is fully covering the sensors Field of View at the preferred
background distance, then hold the PROG button for 1 second
●
The LED indicators, Th1 and Th2 (both GREEN), will now go from ON to OFF status to
confirm entering programming mode.
●
Once the programming mode is completed, the sensor enters the “time delay for
operation mode” for 2 seconds (default). See
to configure this
parameter.
●
After that, LED indicators, Th1 and Th2, will turn ON and stay fixed (GREEN) to verify
a properly stored background threshold.
Step 2 - Sensor ready
●
The background is now taught in and the sensor is in operation mode.
