Deviation:

The difference between the value of the controlled variable and

the value at which it is being controlled.

Default parameters:

The parameters, or programmed instructions, which are

permanently stored in microprocessor software to provide a

data base.

DIP switch:

A Dual In-line Package switch.

DIN:

German

In a digital

indicating

instrument, the entire span that can be

indicated if fully utilized.

The difference in temperature between set point and stabilized

process temperature.

Percentage of “load ON time” relative to total cycle time.

ER1

(Error

considered

a fatal error; your system will shut

down. When the Series 920

shuts down, all events turn off,

and your program

stops

running. When an

error

occurs,

ER1

OOXX alternately flashes with the parameter you are presently

on. While in either

the RUN or HOLD

mode, press

ENTER to

stop the display from flashing the error code. This will not clear

the

error,

but stops the

error

code from flashing

for

minutes.

To clear an

error,

return

the

SYSTEM

mode

and ENTER the

ER1

parameter. This clears your error unless it is a

reoccuring

error and has not been resolved.

ER2 (Error 2) is considered non-fatal.

If you are in the RUN

mode, your program continues running unless it is a

program

error. ER2

00XX

appears, and alternately flashes along with

the parameter that you are presently on. While in either the

RUN or HOLD mode, press ENTER to stop the display from

flashing the error code. This will not clear the error, but stops

the error code from flashing

for

minutes. Clear an ER2

parameter under the SYSTEM mode. If the error persists, refer

to the

Error

Code list on Page 78 to clear.

An event is an ON/OFF auxiliary output relay signal. You can

use events, based on time, temperature, or other process

variables, to trigger peripheral equipment or process.

These auxiliary outputs

can

be alarms or events.

EV1

and EV2

only appear when

AUX1

and AUX2

EV respectively. You

can change the state of the events only in the HOLD mode.

Auxiliary outputs can be

alarms

or events.

Represents the current SYSTEM file of the Series 920 to be

edited or reviewed.

Under the LINK parameter, FILE? stands

for the file that you want to link to.

The Guaranteed Soak parameter guarantees that the actual

temperature is being controlled within a window around set

point. If exceeded, the step time clock will stop until the actual

temperature is within the soak window.

Selects the maximum percent of power the Series 920 will

output.

Will

not appear if DIP switch

is ON.
