Press FUNC key to select the parameters.

ATTENTION

Appendix D contains instructions for using Accutune II for automatic tuning.

Table 4-10 Tuning Parameter Definitions

Lower Display	Upper Display			Parameter
Prompt	Range of Setting			Definition
	or Selection
FUZZY	DIS [factory setting]	FUZZY OVERSHOOT SUPPRESSION FEATURE
		DISABLE—Disables fuzzy overshoot suppression
	ENAB	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.
TUNE	DIS [factory setting]	ACCUTUNE II—On demand tuning algorithm
		DISABLE—Disables ACCUTUNE II
	ENAB	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.
AT ERR	no message under normal	ACCUTUNE II Error Code—Displays AbRT if “TUNE”
	circumstances	has been aborted manually.
	AbRT read only message	See Appendix D.
	displayed if tuning has been
	manually aborted
PB	0.1 % to 999.9 %	PROPORTIONAL BAND or GAIN—Which of these
or	or	prompts is displayed depends on the selection made for
GAIN	0.1 to 999.9	control group parameter “PBorGN” (proportional band or
	[factory setting = 1.0]	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.
