Output Menu

Use the Output menu to enable and configure heat and cool

outputs.

Heat/Cool Output Type

Choose the output type, or disable the heat or cool output. For

more information about each output type, see the Tuning and

Control chapter. (If an output is used for process variable re-

transmit, the disabled option is not available. To disable the

output, first disable process variable retransmit for the output.

See Heat/Cool Output Retransmit on page 148.)

Values:

See Table 6.13

Default:

TP (2) for heat, disabled (0) for cool

Description

Time

Proportioning

TP

2

The output is switched on and off once during a

user-selected cycle time. Within each cycle, the

duration of on versus off time is proportional to the

percent output power.

On/Off

on/off

1

The output is either full on or full off.

None

disabled

0

The output is not used for control and is available

for another use, such as an alarm output.

Three-Phase

Distributed

Zero Crossing

3P DZC

5

Same as DZC, but for three-phase heaters wired in

delta configuration. For grounded Y configuration,

use DZC instead.

Serial DAC

SDAC

4

Use this option if a Serial DAC is connected to the

output. If you set the output type to SDAC, the con-

troller assigns digital output 34 as a clock line for

the Serial DAC.

Distributed

Zero Crossing

DZC

3

The output on/off state is calculated for every ac

line cycle, which means that the output turns on

and off multiple times per second. Use DZC with

solid state output devices or a Dual DAC. Not rec-

ommended for use with electromechanical relays.
