Parameter Definition

PROPORTIONAL BAND (simplex) is the percent of the range of the measured variable for which a proportional controller will produce a 100 % change in its output.

GAIN is the ratio of output change (%) over the measured variable change (%) that caused it.

G = 100 / %PB where PB is the proportional band(in %)

If the PB is 20 %, then the Gain is 5. And, at those settings, a 3 % change in the error signal (SP-PV) will result in a 15 % change in the controller's output due to proportional action. If the Gain is 2, then the PB is 50 %.

Also defined as "HEAT" Gain on Duplex models for variations of Heat/Cool applications.

The selection of Proportional Band or Gain is made in the CONTROL parameter group under prompt PBorGAIN.

RATE action, in minutes, affects the controller's output whenever the deviation is changing; and affects it more when the deviation is changing faster.

RSET MIN = Reset in Minutes per Repeat

RSET RPM = Reset in Repeats per Minute

RESET (or Integral Time) adjusts the controller's output in accordance with both the size of the deviation (SP–PV) and the time that it lasts. The amount of the corrective action depends on the value of Gain. The Reset adjustment is measured as how many times proportional action is repeated per minute or how many minutes before one repeat of the proportional action occurs.

Used with control algorithm PID-A or PID-B.

Also defined as "HEAT" Reset on Duplex models for variations of Heat/Cool applications.

ATTENTION The selection of whether Minutes per Repeat or Repeats per Minute is used is made in the CONTROL parameters group under the prompt MINorRPM.

MANUAL RESET is only applicable if you use control algorithm PD WITH MANUAL RESET in the Algorithm Set Up group. Because a proportional controller will not necessarily line out at setpoint, there will be a deviation (offset) from setpoint. This eliminates the offset and lets the PV line out at setpoint.

ATTENTION Bias is shown on the lower display.

PROPORTIONAL BAND 2 or GAIN 2, RATE 2, and RESET 2 parameters are the same as previously described for “Heat” except that they refer to the cool zone tuning constants on duplex models or the second set of PID constants, whichever is pertinent.

This is the same as above except that it applies to Duplex models for the "COOL" zone of Heat/Cool applications or for the second set of PID constants.
