Encoding of binary inputs’ combinations: 
Language index ->  given by display setting  1 2 3 4 5 6 7 
Lang sel int A  0  1 0 1 0 1 0 1 
Lang sel int B  0  0 1 1 0 0 1 1 
Lang sel int C  0  0 0 0 1 1 1 1 
 
Hint:
 
Warning – each language change causes the restart of the respective display (not the whole controller), so 
the display’s control panel won’t react until the restart has finished (~ 5s). 
Value 0 in the table denotes that the corresponding input is not active or not configured. 
If more than 7 languages are present in the controller, it is not possible to force languages with index higher 
than 7 using these binary inputs. 
The reaction on BI combination change is 1s delayed not to react on transient combinations if a rotary 
selector switch is used. 
Lang sel D#2 A 
Lang sel D#2 B 
Lang sel D#2 C 
Set of binary inputs for forcing alternative languages. This set of inputs is switching the controller’s external 
terminal with address #2 – for IG-based controllers the IG-Display, for IS-based controllers the IS-Display 
with address #2.
