3.2.1  Use With Leybold Transmitter Controllers 

See Leybold sales literature and data sources for controllers and our range of 
sensor cables on our internet home page (

→

 

 [6]). 

 

 

Caution

Caution: data transmission errors 
If the transmitter is operated with the RS232C interface and a fieldbus 
interface at the same time, data transmission errors may occur. 
The transmitter must not be operated with the RS232C interface and 
Profibus at the same time. 

 

 

 
 

 

Procedure 

  Plug the sensor connector into the transmitter and secure it with the locking 

screws. 

  Connect the other end of the sensor cable to the Leybold controller and 

secure it. 

 

 

  The transmitter can now be operated with the Leybold controller.
