Item Call-Out Description

Select Mode

and Loop 1/2

Push Button

Pressing this push

button in operator

mode with an active

two loop control

scheme (cASc, L.LiM, or

h.LiM) selects the loop

under display panel

control. It toggles from

one loop to the other

each time it is pressed.

If this push button is

held for three seconds,

it causes engineer

mode to be entered.

Pressing it in engineer

mode causes a return

to operator mode.

Loop 1

Select

Indicator

These indicators are for

the two loop control

schemes cASc, L.LiM,

and h.LiM. Either one

of these two indicators

will activate to show

which loop is under

display panel control

as selected by the

Mode push button.

Loop 2

Select

Indicator

Easy-Tune

Status

This status indicator

blinks during Easy-Tune

operation. A steady-

state-on condition

indicates Easy-Tune

terminated with an

error. It stops blinking

when Easy-Tune

completes successfully.

Watchdog

Condition

Indicator

This indicator activates

whenever the

controller detects an

internal processor

failure. When active,

all outputs are forced

to their power-off state.

Attempt to restart the

controller by cycling

power.

3.3 Auxiliary Operator Access

To facilitate operator access for auxiliary data input

and selected parameter modification, an engineer

mode oPEr menu is provided. This menu allows

display panel entry of logical and analog signal

constants, process variable alarm values, high/low

output limit values, and PID values. It also pro-

vides operator capabilities to execute the Easy-

Tune sequence. Access to menu items is

controlled through the conF-oPr enabling parame-

ters. Because the oPEr menu parameters and their

corresponding conF-oPr enabling parameters are

accessed in engineer mode, they are described in

Tables 3-3 and 3-4, which appear later as part of

the engineer mode information.

3.4 Operator Mode Overflow/

Underflow Indication

Overflow indicators are plus signs (+) and under-

flow indicators are negative signs (-). Illustrations

of the overflow and underflow conditions are pro-

vided in Figure 3-3. They appear in the affected

dro and are decimal point sensitive. If these indica-

tors repeatedly appear, the decimal point should be

repositioned with the conF-cn.1(cn.2)-dP parame-

ter described in Table 7-3. Adjusting this parame-

ter requires knowledge of engineer mode, which is

described next in this section.
