RSET MIN
or
RSET RPM
0.02 to 50.00
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.
MAN RSET
–100 to +100
(in % output)
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.
PROPBD2
or
GAIN 2
0.1 to 9999 %
or
0.001 to 1000
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.
RATE2MIN
0.00 to 10.00 minutes
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.
RSET2MIN
RSET2RPM
0.02 to 50.00 These are the same as above except that they apply
to Duplex models for the "COOL" zone of Heat/Cool
applications or for the second set of PID constants.
