The expression editor has the following features:
• The following signals can be used:
CA1, CA2, CD1, CD2 or LZ (or LY)
• The following signals can be inverted:
!A1, !A2, !D1, !D2, or !LZ (or !LY)
• The following logical operators are available:
"+" : OR operator
"&" : AND operator
"^" : EXOR operator
Expressions according to the following truth table can be

Example:
Broken belt detection for Logic Y
This example describes the programming for a so-called
“broken belt detection” for fan applications.
The comparator CA1 is set for frequency>10Hz.
The comparator !A2 is set for load < 20%.
The comparator CD1 is set for Run.
The 3 comparators are all AND-ed, given the “broken belt
detection”.
In menus [621]-[625] expression entered for Logic Y is
visible.
