Programming switch 

 

The programming switch must be connected to the control unit 
in order to change parameters and switching values. 
The control unit SILAS does not accept values, which are 
changed without an active connected programming switch. 

 

 

 

Programming cable 

 

The programming cable is used to connect the Ex p control unit 
to the PC. This must be connected to the control unit and PC in 
order to change parameters and switching values.
