Table 3-1. Operator Mode Display Items
Item Call-Out Description
20 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.
21 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.
22 Loop 2
Select
Indicator
23 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.
24 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-
T u n e s e q u e n c e . A c c e s s t o m e n u i t e m s i s
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.
