OFF Reset Offset Value is retained in memory when the process input is not within the Proportional Band.
Art1 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 Art1 time and the rtE1 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 1 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 1 is set to 0, Fbd1 and Frt1 below will not appear.
Fbd1 Fuzzy Logic Error Band: Select 0 to 4000 °F, °C, or counts. Sets the bandwidth of the Fuzzy Logic. Set Fbd1 equal to PID proportional band (Pb1) for best results. Self Tune, when used, calculates this value. Will not appear if Fi 1 is 0.
Frt1 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% output). Multiply this value by 3. Set Frt1 to this calculated value. Self Tune, when used, calculates this value. Will not appear if Fi 1 is 0.
PEA1 The Peak feature stores the highest input the control has measured for Zone 1 since the last reset or Power On. At Power On, PEA1 is reset to the present input value. To manually reset the value PEA1 must be in the lower display. Press the ENTER key to reset. PEA1 will be reset and display the present input value.
UAL1 The Valley feature stores the lowest input the Instrument has measured for Zone 1 since the last reset or Power On. At Power On, UAL1 is reset to the present input. To manually reset the value UAL1 must be in the lower display. Press the ENTER key. UAL1 will be reset and display the present input value.
