Logic programming – Function blocks 
 
 Choose the number of inputs which you would like to attach to the function block. 
 Then click the Parameter tab and choose the zone by checking the boxes. 
 
 
If only AND logic is needed, leave the Zone 2 AND function block inputs unchecked. 
If additional OR logic is required in the application, the inputs can be combined 
using the Zone 1 and Zone 2 AND function blocks and subsequently connecting to 
the internal OR function block. 
 Finally select the output for Fast shut off.
