OFF Reset Offset Value is retained in memory when the process input is not within the Proportional Band.
Art2 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 Art2 time and the rtE2 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).
Fi 2 Fuzzy Logic Intensity: Select 0 to 100%. 0% is OFF (disables Fuzzy Logic). The function defines the amount of impact Fuzzy Logic will have on the output. If Fi 2 is set to 0, Fbd2 and Frt2 below will not appear.
Fbd2 Fuzzy Logic Error Band: Select 0 to 4000 °F, °C, or counts. Sets the bandwidth of the Fuzzy Logic. Set Fbd2 equal to PID proportional band (Pb2) for best results. Self Tune, when used, calculates this value automatically. Will not appear if Fi 2 is set to 0.
Frt2 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 (Output is100%). Multiply this value by 3. Set Frt2 to this calculated value. Self Tune, when used, calculates this value automatically. Will not appear if Fi 2 is set to 0.
PEA2 The Peak feature stores the highest input the control has measured for Zone 2 since the last reset or Power On. At Power On, PEA2 is reset to the present input. To manually reset the value PEA2 must be in the lower display. Press the ENTER key to reset. PEA2 will be reset and display the present input value.
UAL2 The Valley feature stores the lowest input the Instrument has measured for Zone 2 since the last reset or Power On. At Power On, UAL2 is reset to the present input. To manually reset the value UAL2 must be in the lower display. Press the ENTER key. UAL2 will be reset and display the present input value.
