RS485 interfaces 

Communication with the RS485-3 interface reserved for 
the customer can be configured here. 
 
The "Protocol/Module" menu item defines whether 
communication is via ModBus-RTU or PROFIBUS 
module. 
 
If "ModBus-RTU" is set, the baudrate and address 
settings can be changed. 
 
If "PROFIBUS module" is set, the baudrate and address 
settings cannot be changed because they are 
automatically set to the requirements of the PROFIBUS 
module. 
 

Adjustments Compressors 

The various compressor settings can be defined here 
and new compressors can be added or existing 
compressors deleted. 
 

Adjustments extension modules 

The extension module parameters can be set here. 

 

Language 

The flag on the key shows the current language setting. 
Touching this key opens the language selection screen. 
 

Code 

The code for locking and unlocking settings can be 
entered here (for more information see section 5.9 
"Codes").
