The channel IA, IB, IC, and IN current
values (in A primary) display continually 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.
The “Press CNTRL for Local Control”
message displays in a “2 seconds per screen”
rotation with the default metering screen 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
in
Section 7: Inputs, Outputs,
Timers, and Other Control Logic
for more
information on local control.
If display point labels (e.g., “79
DISABLED” and “BREAKER OPEN”) are
enabled for display, they also enter into the
“2 seconds per screen” rotation.
The following table and figures demonstrate the correspondence between changing display point
states (e.g., DP2 and DP4) and enabled display point labels (DP2_1/DP2_0 and DP4_1/DP4_0,
respectively). The display is on a 2-second rotation for each screen.
The display point factory settings are:
DP1 = IN2
(optoisolated input IN2)
DP2 = 52A
(Relay Word bit 52A = IN1 in factory settings)
