Parameter
Definition
FUZZY OVERSHOOT SUPPRESSION FEATURE
DISABLE—Disables fuzzy overshoot suppression
ENABLE—The recorder will use fuzzy logic to suppress
or mimimize any overshoot that may occur as a result of
the existing tuning parameters. It does NOT change the
parameters.
ACCUTUNE II—On demand tuning algorithm
DISABLE—Disables ACCUTUNE II
ENABLE—TuneOF will be displayed as a status
message. Use the Increment or Decrement key to
toggle status to TuneON. New PID parameters will be
entered automatically when tuning is complete.
ACCUTUNE II Error Code—Displays AbRT if "TUNE"
has been aborted manually.
See Appendix D.
PROPORTIONAL BAND or GAIN—Which of these
prompts is displayed depends on the selection made for
control group parameter "PBorGN" (proportional band or
gain). Both proportional band and gain are ways of
expressing the proportional component of control. See
the description of control group parameter "PBorGN" for
details concerning the two terms.
ATTENTION
If control group parameter "OUTALG"
is "RLYD" (relay duplex), "Tcur" (time/current duplex), or
"CurT" (current/time duplex), and you are using the
recorder in a heat/cool application, PB or GAIN is used
for heat control. Cooling control would use PB2 or GAIN
2 described later in this table.
