Engineering Span, Engineering Zero

These values set the engineering

unit representation of the input

signal over the input range.

dFLt

Digital Filter

Specifies the time constant in

seconds for a first order filter

through which the input is

processed. The filter dampens the

higher frequency signal

components usually associated with

noise. Selections:

nonE 4.2 75.0 1200

If any of these values are accidentally overwritten,

reference the factory calibration sheet provided

with the controller and enter the values again.

Prompt Description Dft

tYPE

The prompt selection

is cAL. 1-5V

biAS

GAin

Voltage Calibration Constants

These two parameters are the zero

offset and span constant for the volt

input range.

b.MV

G.MV

Millivot Calibration Constants

These two parameters are the zero

offset and span constant for the

miilivolt input range.

b.cJc

Cold Junction Compensation

Constant

This parameter accounts for the

differences between the actual

module pin temperature and the

temperature measured by the CJC

sensor from within the module.

G.rtd

RTD Hardware Compensator

This parameter accounts for the

differences in the module’s

hardware characteristics between

the 3 and 4 wire RTDs.

5.4 Analog Output 1 (AO1)

A standard 0-20 mA or 4-20

mA analog signal is trans-

mitted by the controller

through analog output 1

(AO1). It is defined as percent

output value from 0 to 100.

The single signal conditioning parameter (bASE)

for analog output AO1 is defined in Table 5-9. Ta-

ble 5-10 lists the analog output registers and regis-

ter input connection paths; the register stores the

analog value before it is conditioned (bASE) by

hardware and transmitted. Although there are

three analog output database locations (AO1 -

AO3); only the output from AO1 is transmitted ex-

ternally by the controller. The value contents

stored in analog output registers AO2 and AO3 can

be looped-back if selected by the input connections

of the math function block or control scheme block

(only Ao3 for the control scheme block).
