OPERATING PROCEDURES

FACEPLATE OPERATION

4 - 4

I-E96-117B

Annunciators

There are nine annunciators on the station faceplate. They are
located above the control output (CO) bar graph. Table

4-3

lists

the function of the annunciators.

Bar Graph Displays

There are three bar graph displays (see Figure

4-1

). They dis-

play the process variable, control output, demand output, ana-
log inputs one and two, or set point depending on the display
options selected for each mode of operation.

Tables

lists all combinations of display

options for each mode of operation. Refer to the bar graph
option settings recorded in the user setting section of
Tables

when necessary.

Membrane Pushbuttons

There are ten membrane pushbuttons on the SAC station face-
plate. The membrane pushbuttons are momentary, single posi-
tion contacts. Table

4-4

lists the membrane pushbuttons and

their function. See Figure

2-2

for a flow diagram of the SAC

station operation.

Manual Override Switch

The manual override switch forces the control system into open
loop control. The operator has direct control of the process
from the

OUT

pushbuttons. The process can be monitored by

the user definable display options. Placing the switch in the
manual (

) position overrides all station operating modes and

locks the station in manual override. Return the switch to the
auto (

) position to unlock manual override.

Table 4-3. Annunciators

Annunciator

Indicates

AUT

The station is operating as an automatic basic station.

CAS

The station is operating as a cascade station.

DEV

Not used at this time.

OUT

The value currently displayed on the alphanumeric display is the control output (CO).

OUT TRK

Control output tracking is active.

RAT

The station is operating as a ratio station.

SET

The value currently displayed on the alphanumeric display is the set point (SP).

SPT TRK

Set point tracking is active.

VAR

The value currently displayed on the alphanumeric display is the process variable (PV).
