4.3.11 Control Parameters Set Up Group

Introduction

If the recorder hardware supports outputs, the functions in this group are used to configure how the recorder will control the process. (If configuring a limit controller, see Subsection 4.3.22 for special limit control configuration parameters.)

Control group prompts

Table 4-9lists all the function prompts in the control set up group. For a 2-pen recorder, the desired input

channel is displayed on the left side of the operator interface. Press FUNC to select channel. Press

SETUP key until “CONTRL” appears in the lower display. Press FUNC key to select the parameters.

Table 4-9 Control Parameter Definitions

Lower Display		Upper Display	Parameter
Prompt	Range of Setting		Definition
		or Selection
CONTRL	ENAB	[factory setting]	Enables control.
	DIS		Disables control. If control is disabled here, the rest of the
			functions in this group will not be displayed. All alarm
			group functions will be displayed.
NumSPs	ONE [factory setting]		NUMBER OF SETPOINTS—If this is set to TWO, then
	TWO		the operator will be able to select the setpoint using the
			UseSPn operating parameter prompt.
OUTALG			OUTPUT ALGORITHM —Use to specify the type of
			output.
	RLY	[factory setting]	RELAY SIMPLEX—Type of output using one SPDT
			relay. Its contacts can be wired for normally open (NO) or
			normally closed (NC) action.
			Control group function “HYST” is affected.
			The second relay is available for alarming, and alarm
			group functions will be displayed for Alarm 2.

			functions will be displayed.
	CUR		CURRENT SIMPLEX—Type of output using one 4 mA to
			20 mA signal that can be fed to a positive or negative
			grounded load of 0 to 600 ohms. The current output
			signal can be recalibrated as described in Section 5 to
			use any range within 4 mA to 20 mA to represent 0 to 100
			% output.
	CurT		CURRENT/TIME DUPLEX (Relay = Heat)—Variation of
			duplex with current active for 0 % to 50 % output (tuning
			set 2) and relay active 50 % to 100 % output (tuning set
			1).
