Figure 7.30 Rotating Default Display
Replaces Traditional Panel Light Installations
There are sixteen (16) of these default displays available in the SEL-311C.
Each default display has two complementary screens (e.g.,
BREAKER CLOSED
and
BREAKER OPEN) available.
General Operation of
Rotating Default
Display Settings
The display settings are enabled using the EDP setting. Set EDP to the number
of display settings that are desired (N, 1–16).
SEL
OGIC control equation display point setting DPn (n = 1–16) controls the
display of corresponding, complementary text settings:
DPn_1 (displayed when DPn = logical 1)
DPn_0 (displayed when DPn = logical 0)
Make each text setting through the serial port, using the command SET T.
View these text settings by using the serial port command SHO T (see
Section 9: Setting the Relay and Section 10: Serial Port Communications and
Commands). These text settings are displayed on the SEL-311C front-panel
display on a time-variable rotation through use of Global setting SCROLD
(see Rotating Default Display on page 11.12 for more specific operation
information).
The following settings examples use optoisolated inputs IN101 and IN102 in the
display points settings. Local bits (LB1–LB4), latch bits (LT1–LT4), remote
bits (RB1–RB8), setting group indicators (SG1–SG6), and any other
combination of Relay Word bits in a SEL
OGIC control equation setting can
also be used in display point setting DPn.
Settings Examples
The settings examples provide the replacement solution shown in Figure 7.30
for the traditional indicating panel lights in Figure 7.29.
Reclosing Relay Status Indication
Make SELOGIC control equation display point setting DP1:
DP1 = IN102
Make corresponding, complementary text settings:
DP1_1 = 79 ENABLED
DP1_0 = 79 DISABLED
Display point setting DP1 controls the display of the text settings.
