4.2 Tuning Parameters Set Up Group
Introduction
Tuning consists of establishing the appropriate values for the tuning
constants for a single loop controller. These parameters are also for Loop
1 of a 2 Loop or Cascade control configuration.
Adaptive Tune feature automatically selects Gain, Rate, and Reset.
This section also contains Keyboard Lockout/Security selections.
Set this group last
Because this group contains functions that have to do with security and
lockout, we recommend that you configure this group last, after all the
other configuration data has been loaded.

Table 4-1 lists all the function prompts in the Tuning setup group and
their definitions.

GAIN
0.1 to 9999%
or
0.001 to 1000
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 Prop. Band or Gain is made in the
"CONTROL" parameter group under prompt
"PBorGAIN."
GAIN VALn
Read Only
LOOP 1 GAIN - This is the value being provided by
Gain Scheduling when enabled.
RATE MIN
0.00 to 10.00 minutes
0.08 or less = OFF
RATE action, in minutes, affects the controller's
output whenever the deviation is changing; and
affects it more when the deviation is changing faster.
Also defined as "HEAT" Rate on Duplex models for
variations of Heat/Cool applications.
