Introduction

Tuning 2 group prompts

Tuning 2 (Loop 2) consists of establishing the appropriate values for the tuning constants for Loop 2 on 2-Loop or Internal Cascade control.

Loop 2 is only available on Expanded Model DC330E.

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

Definition

The definitions listed for the parameters at the left are the same as those listed previously for the Tuning Set Up group parameters except they are for Loop 2.

The table below shows you how to use them for Duplex Heat/Cool applications.

DUPLEX OUTPUT RANGES

0 to 50 %— TUNING SETS 2 AND 4: COOL

50 to 100 %— TUNING SETS 1 AND 3: HEAT

Duplex	Heat
Output	or	Loop 1	Loop 2
Range	Cool
0 to 50 %	Cool	PID SET 2	PID SET 4
		Gain 2	Gain 4
		Rate 2	Rate 4
		Reset 2	Reset 4
		Cycle 2	Cycle 4
50 to 100 %	Heat	PID SET 1	PID SET 3
		Gain	Gain 3
		Rate	Rate 3
		Reset	Reset 3
		Cycle	Cycle 3

Set 4 Tuning Parameters are not available when ACCUTUN2 is configured for SP+PV.

Gain Scheduling prompts are only available when PID SETS in the Loop 2 Control Set Up group is configured for GAIN S.
