Note: The PROTEÇÃO BLOQUEADA operator control is not
operable with the factory settings.
PROTEÇÃO
BLOQUEADA
Press the DESPERTAR operator control pushbutton to wake up the
SEL-351P if the front panel is dark (the unit put itself to sleep after
an extended outage). After the unit wakes up, the front panel
illuminates, and the unit can then be interrogated via the front panel
or serial port.
The DESPERTAR operator control is also used to turn on the
SEL-351P after the battery has been installed (see the installation
steps in the Installation section).
The SEL-351P wakes up automatically from an extended outage
when 120 Vac power returns to the unit.
DESPERTAR
Press the FECHAR operator control pushbutton to close the
recloser. Corresponding RELIGADOR FECHADO LED
illuminates to indicate the recloser is closed.
The FECHAR operator control pushbutton does not
have to be
continually pressed to allow for cold load pickup (i.e., disable fast
curves, and desensitize delay curves and SEF element). There is
automatic allowance for cold load pickup. See Cold Load Pickup
Scheme (No. 33) settings in the Settings section.
Option
: Set a delay, so the operator can press the FECHAR
operator control pushbutton and then move a safe distance away
from the recloser before the SEL-351P issues a close (the FECHAR
operator control comes with no set delay in the factory settings).
With a set delay, press the FECHAR operator control pushbutton
momentarily, and notice that the RELIGADOR FECHADO LED
flashes on and off during the delay time, indicating a pending close.
Abort the pending close by pressing the FECHAR operator control
pushbutton again or by pressing the ABRIR operator control
pushbutton. This delay setting for the FECHAR operator control is
PB8D (range: 0 to 3600 cycles; factory-set at 0 cycles – no delay).
The delay is set via the SET G command (PB8D is not an EZ
setting). See Section 1: Factory-Set Logic in the SEL-351P
Manual Técnico for more information.
