ArtE Approach Rate Time: Select OFF, 0.01 to 99.99 minutes. The function
defines the amount of Rate applied when the input is outside of the
Proportional Band. The ArtE time and the rtE time are independent and have
no effect on each other. To increase damping effect and reduce overshoot
set the approach rate time for a value greater than the natural rise time of
the process (natural rise time = process value time to set point).
Fint Fuzzy Logic Intensity: Select 0to 100% . 0% is OFF (disables Fuzzy Logic).
The function defines the amount of impact Fuzzy Logic will have on the out
put. If Fint is set to 0, Fbnd and Frte below will not appear.

width of the Fuzzy Logic. Set Fbnd equal to PID proportional band (Pb1)
for best results. Will not appear if Fint is OFF.
FrtE Fuzzy Logic Rate of Change: Select 0.00 to 99.99 counts/second. For best
initial setting, find the count/second change of process value near set point
1 with output ON 100%. Multiply this value by 3. Set FrtE to this
calculated value. Will not appear if Fint is OFF.
