Function  

Setup 

Th1; Th2  

Both LEDs will go from ON 
(GREEN) to OFF status for 2 
s (default) 

Indicates a properly stored 
background distance 

Th1; Th2 

Both LEDs will stay 
continuously ON (GREEN)  

Indicates that setup is finalized 
and sensor is in operation 
mode 

Operation 

Th1; Th2 

Both LEDs will blink GREEN 
once 

Indicates that an object has just 
left the Field of View

Operating mode 3  

Description 

In mode 3, a switching window is taught in between the sensor and the background

 

     

 

   

   

 

 

 

 

 

 

threshold. The sensor is activated as soon as an object or a person enters the selected

 

 

   

   

     

     

 

 

 

 

trigger zone(s). This mode is used for monitoring a frontal approach or level fulfilment, for

 

 

 

   

 

 

   

 

   

 

 

 

instance.  
 

 

Please note that mode 3 is not recommended for monitoring lateral movement or

 

 

 

     

 

   

 

 

   

detecting small objects. Obstacles that partially enter the sensors Field of View

 

 

 

 

 

 

 

 

 

   

 

may be detected at an incorrect distance, caused by an averaging effect (refer to
