Rotating Display
The six relay elements, 87A, 87B, 87C, followed by IA, IB and IC display if
no local control is operational (i.e., no corresponding switch position label
settings were made) and no display point labels are enabled for display.
In addition to the six elements, a message labeled “Press CNTRL for Local
Control” displays if at least one local control switch is operational. It is a
reminder of how to access the local control function. See the preceding
discussion in this section and Local Control Switches (NLBn, SLBn, CLBn,
PLBn) on page 4.5 in Section 4: Control Logic for more information on local
control.
If display point labels are also enabled, the “Press CNTRL for Local Control”
displays for two seconds and then is followed by enabled display point labels
in subsequent two-second rotations. The display is on a two-second rotation
for each screen.
