Operating mode 2 

Description 

Mode 2 is used for applications such as counting moving objects/people, and monitoring

     

 

 

 

   

 

 

 

 

 

object height. A single background threshold is used to set a trigger zone. The sensor is

 

   

 

 

   

   

   

 

 

 

   

activated as soon as an object leaves the programmed trigger zone in the light beam.  

Setup 

 

Figure 11. Mode 2 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 by default (see ​

Section 5.3

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.
