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”.

37

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”
