SEL-351P Manual Técnico
If the SEL-351P trips, recloses, then trips again, the SEL-351P goes to the lockout state (front-
panel LOCKOUT LED illuminates). The shot counter screen then appears as:
SET RECLOSURES=3
RECLOSE COUNT =3
If the recloser is closed, the reset timer times out (79RSLD = 600), the SEL-351P goes to the
reset state (front-panel LOCKOUT LED extinguishes and RESET LED illuminates), and the shot
counter returns to 0. The shot counter screen appears as:
SET RECLOSURES=3
RECLOSE COUNT =0
Extra Local Control
Use extra local control to enable/disable schemes, trip/close breakers, etc., via the front panel.
In more specific terms, local control asserts (sets to logical 1) or deasserts (sets to logical 0) what
are called local bits LB1 through LB8. These local bits are available as Relay Word bits and are
used in SEL
OGIC
®
Control Equations (see Row 25 in Table 9.4).
Local control can emulate the following switch types in
Figure SECTION 11: .1 through Figure
SECTION 11: .3.

Figure SECTION 11: .2: Local Control Switch Configured as an
OFF/MOMENTARY Switch
