Dead band:

A temperature band between heating and cooling functions.

Derivative:

Anticipatory action that senses the rate of change of tempera-

ture, and compensates to minimize overshoot and undershoot.

Also “rate.”

When ACCESS (0) is entered under the SETUP menu, the

CALIB

parameters appear. These parameters setup the

Real

Time and the calibration offset of the process variable.

Accepts the sensor input and

scales

it to degrees Celsius,

Fahrenheit, or Units of measure. This parameter will not appear

if DIP switch

is ON.

Control system with a sensing device for process variable

feedback.

Allows the operator to clear a file of the Series 920.

Electronic means used to compensate for the effect of the

temperature at the cold junction.

"Clean”,

or completely cleared-of-user-program-information,

start-up condition. (Factory settings.)

This parameter determines whether the communications

protocol will be STX/ETX or XON/XOFF. This parameter can

be found in the SPCLFUNC menu. This parameter will not

appear if you do not have communications.

Represents the device identification number as required for the

ANSI X3.28

communications protocol for the Series

920. This

parameter will not appear if you do not have communications.

The Cooling Cycle Time expressed in seconds for a controller to

complete one ON/OFF cycle. The time between

successive

turn ons. This parameter

will not appear if: 1.

2. Your Series 920 has a

4-20mA

output and OUT

CL or

CL/HT.

The Heating Cycle Time usually expressed in seconds for a

controller to complete one ON/OFF cycle. Time between

successive turn ons. This parameter will not appear if:

OUT

CL,

or PB H

2. Your Series 920 has a

4-20mA

output

and OUT

HT or

HT/CL.

The time necessary to complete a full ON-through-OFF period

in a time proportioning control system.

Represents the number of days that the 920 waits until AUTO-

START takes place. Each time

0O:OO

is achieved, one day has

gone by.

The Dead Band parameter representing the area where no

heating or cooling takes place in a

heat/cool

proportional

control. This parameter will not appear if OUT

HT or CL.
