INPUTS
The filter inputs for measured
values are displayed with the
threshold, mode and effect.
They have a flexible structure for
the creation of larger/smaller
comparisons or window compari-
sons.
Thus the following filter conditi-
ons can easily be realised:
1) Simple larger/smaller compari-
son (switch if the input variable is
smaller/larger than the
threshold). Example 1 – Switch if
temperature 1 > 35 °C: mode A
">"; threshold A 35; mode B
"off"; threshold B any value;
effect "thru".
2) "Window comparison" (switch
if the input variable is inside/outsi-
de a defined range) Example 2 –
Switch if voltage 1 is between
210 V and 240 V: Mode A ">";
threshold A 210; Mode B "<";
threshold B 240; effect "thru"
Example 3 – Switch if humidity 1
is less than 30 % or greater than
80 %: Mode A ">"; threshold A
30; Mode B "<"; threshold B 80;
effect "invert"
