Installations
There are eight (8) of these default displays available in the SEL-351P. Each default display has
two complementary screens (e.g., BREAKER CLOSED and BREAKER OPEN) available.
General Operation of Rotating Default Display Settings
SEL
OGIC
Control Equation display point setting DPn (n = 1 through 8) 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 using the serial port command SHO T (see Section 9: Setting the SEL-351P Recloser
Control and Section 10: Serial Port Communications and Commands ). These text settings are
displayed on the SEL-351P front-panel display on a 2-second rotation (see Rotating Default
Display in Section 11: Additional Front-Panel Interface Details for more specific operation
information).
The following factory settings examples use optoisolated inputs IN101 and IN102 in the display
points settings. Local bits (LB1 through LB4), latch bits (LT1 through LT4), remote bits (RB1
through RB8), setting group indicators (SG1 through 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.
