OUT ALG

The OUTPUT ALGORITHM lets you select the type

of output you want. Selections are model dependent.

For example, current output models cannot be

configured for Time Proportioning Simplex Output.

TIME

TIME SIMPLEX — This Output algorithm uses

Digital Output 3 for Time Proportional Control. The

output is updated per the Loop sampling rate

selection. Time Proportional Output has a resolution

of 4.44 msec. Cycle Time is adjustable from 1 to

120 seconds.

CURRENT

CURRENT SIMPLEX — Type of output using one

4 to 20 mA signal that can be fed into a positive or

negative grounded load of 0 to 1000 ohms. The

signal can be re-calibrated for any desired range

from 4 to 20 mA for 0 to 100% output.

TIME DPLX

TIME DUPLEX — This Output algorithm uses Digital

Outputs 3 and 4 for Duplex Time Proportional

Control. The outputs are updated per the Loop

sampling rate selection. Time Proportional Output

has a resolution of 4.44 msec. Cycle Time is

adjustable from 1 to 120 seconds.

CUR DPLX

CURRENT DUPLEX is similar to current simplex but

uses a second current output. The second output is

usually scaled so that zero and span correspond

with 0% and 50% output (cool zone). When the

output is 0 to 50%, the controller uses tuning

parameter set #2, when the output is 50 to 100% it

uses set #1.

Other prompts affected: "4-20 RNG”

CUR TIME

CURRENT/TIME DUPLEX (Digital Output 3 =

HEAT) is a variation of duplex with current active for

0 to 50% output (tuning set 2) and Time is active 50

to 100% output (tuning set 1).

Other prompts affected: "4-20 RNG”

TIME CUR

TIME CURRENT DUPLEX (Digital Output 3 =

COOL) is similar to "CUR-TIME" except that current

is active for 50 to 100% and Time is active for 0 to

50%.

Other prompts affected: "4-20 RNG”.
