If the displayed threshold value is GREEN, the result of the frequency calculation is positive.
If the displayed threshold value is RED, the parameters need to be modified.
Enable Error Out When this parameter is selected, an output (“E
RROR”) is made available which signals that
an error has been detected by the function block.
In the application program, this output is used to prevent startup after an error.
The hysteresis only needs to be modified if the following applies: fM = green; fm = red
