*  When ordering

  without HMI  

 

  please observe:

Each AKS 4100/AKS 4100 

must always be programmed 

via the HMI display unit. 

The HMI display unit can be 

ordered separately and there 

are two possibilities:

• 

084H4540

 

AKS 4100/4100U HMI display 

unit with rear cover and 

mounting bracket.  

The mounting bracket is 

very useful when the AKS 

4100/4100U have to be 

programmed.  

The same AKS 4100/4100U 

HMI display unit can be used 

to programme more AKS 

4100/4100U and both Cable 

and Coaxial versions. 

• 

084H4548

 

AKS 4100/4100U HMI display 

unit (usually spare part).
