10  Operation

10.1  Function check

After power-on the device is in the operating mode� It carries out its measurement 

and evaluation functions and generates output signals according to the set 

parameters�

 

Check whether the unit operates reliably�

10.2  Operating and diagnostic messages via IO-Link 

IODD and IODD descriptive text as a pdf file at: → www.ifm.com

10.3  Operating indication by LEDs

The following indications refer to the factory settings� In this state OUT1 = Hno 

and OUT2 = Hnc� 

Both yellow LEDs (LED1 and LED2, 

→ 8) indicate the switching status of output
