4.12 Loop 2 Control Parameters Set Up Group

Introduction

Control 2 group prompts

The functions listed in this group deal with how Loop 2 of a Two-Loop process controller will control the process including: PV source, Number of tuning parameter sets, Setpoint source, Tracking, Power-up recall, Setpoint limits, Output direction, rate and limits, Dropoff, Deadband, and Hysteresis.

Only available on Expanded Model DC330E-XX-XXX.

Table 4-11 lists all the function prompts in the Control 2 Set Up group and their definitions.

FORCE MA

PID SETS

	FORCE MANUAL/AUTO links Auto/Manual modes. If
	either loop changes mode due to a front panel change,
	digital input action, or failsafe action, the other loop tracks
	that mode.
DISABL	DISABL— Disables FORCE MA.
LINK12	LINK12— Links modes for both loops.
	NUMBER OF TUNING PARAMETER SETS— This
	selection lets you choose one or two sets of tuning
	constants (gain, rate, and reset).
1 ONLY	ONE SET ONLY— Only one set of tuning parameters is
	available. Configure the values for:
		Gain (proportional band)
		Rate
		Reset Time
		Cycle Time (if time proportional is used)
2KEYBD	TWO SETS KEYBOARD SELECTABLE— Two sets of
	tuning parameters can be configured and can be selected
	at the operator interface or by using the Digital Inputs.
	Press	LOWER DISPLAY	key until you see PID SET3 or
	PID SET4 then press		or	to switch between
	sets. Configure the values for:
		Gain #3, Rate #3 , Reset #3, Cycle #3 Time
		Gain #4, Rate #4, Reset #4, Cycle #4 Time
	See Subsection 5.10 for procedure.
