RS H:

RT:

Represents the rate at which the set point changes in a given

time.

RT C:

The Rate (derivative) Cooling function

detemined

by how fast

the error being corrected is increasing. Expressed in minutes.

This parameter will not appear if OUT

HT,

or PB C

RTD:

(parameter)

Allows the

operator

to change the input gain of the RTD input

for different

curves.

This parameter will not appear if the input

type is not RTD whole or RTD tenths, or DIP switch

is ON

The Rate (derivative) for the Heating function that is deter-

mined by how fast the error being corrected is increasing.

Expressed in minutes. This parameter will not appear if OUT

CL or PBH = 0.

Reference

junction:

Reset:

Synonymous with cold junction. See “Cold junction.”

Control action that automatically eliminates offset, or “droop,”

between set point and actual process temperature. Also

“integral.

”

Reset windup

inhibit:

RETURN:

RTD:

Synonymous with anti-reset. See “Anti-reset.”

From any RETURN parameter, you can go back to SYSTEM.

Resistance Temperature Detector. Resistive sensing device

displaying resistance versus temperature characteristics.

Displays positive temperature coefficient.

SE:

Represents the set endpoint that the Series 920 will try to

achieve in the amount of time given. This will be done linearly,

producing a ramp from a beginning set point to an end set

point. Seen only in the RUN mode.

SEC:

The number of seconds that equal total step time to achieve

the temperature of the Series 920.

Set point:

SETPOINT:

Intended value of the process variable.

One of six step types under the PROGRAM menu of the Series

920. Can be programmed as a file or a step to achieve or

maintain a set point.

SP:

Represents the current Set Point. Its primary function is as the

control point of the closed loop.

SPCLFUNC

When ACCESS (5) is selected under the SETUP mode of the

Series 920, the Special Function parameters appear. Here you

can select the input type, degrees, output type, auxiliary and

alarm types among others.

STEP:

Represents the current SYSTEM file step of the Series 920 to

be edited or reviewed.

STOP:

One of six step types under the PROGRAM menu of the

Series

920, that will indicate the end of any file.

Appendix

WATLOW Series 920

User’s

Manual

A reset (integral) heating control action that automatically

eliminates offset, or “droop”, between set point and actual

process temperature in a proportional control. Expressed in

minutes. This parameter will not appear if OUT

CL or PB H

is set to 0.
