41 Reset trip-latched LEDs
when recloser closes Y Y/N
Figure 8 shows the front-panel trip-latched LEDs. They are: TRIP, CURVA RÁPIDA, ALTA CORRENTE,
RELÉ FREQ., and all TIPO DE FALTA LEDs.
These LEDs latch in at the rising edge of trip and remain illuminated - even after power is turned off and then
on again.
Reset trip-latched LEDs when recloser closes = Y:
The trip-latched LEDs extinguish automatically when the recloser closes.
Reset trip-latched LEDs when recloser closes = N:
The trip-latched LEDs extinguish automatically (or are newly latched in) when the SEL-351P trips again.

42 True three-phase voltage
connected N Y/N
If True three-phase voltage is connected to the SEL-351P, the indication provided by A, B, and C TIPO
DE FALTA LEDs is made more secure (see Figure 8).

43 Battery Amp-hours 8.0 6.5-20.0 Amp-hours 0.1
This is the amp-hour rating of the 24 Vdc battery system connected to pins 6 [+] and 2 [-] on POWER
connector J6.

44 % Battery capacity for sleep 20 0-100% 1
The % Battery capacity for sleep setting is typically set at 20% capacity, so that the battery is not totally
depleted during an extended outage.
•
If the % Battery capacity for sleep setting (e.g., 20% capacity) is reached or the temperature-
compensated battery voltage measurement falls below 80% nominal voltage during an extended outage,
the SEL-351P goes to sleep, unless communications are actively ongoing with the SEL-351P.
•
If the % Battery capacity for sleep is set at 0% capacity and the SEL-351P is operating on the battery
during an extended outage, the SEL-351P goes to sleep when the temperature-compensated battery
voltage measurement falls below 80% nominal voltage, unless communications are actively ongoing with
the SEL-351P.
•
If the temperature-compensated battery voltage measurement falls below 70% nominal voltage during an
extended outage, the SEL-351P goes to sleep, regardless of any other conditions.

45 Turn on the 12 V power N Y/N
The Turn on the 12 V power setting turns the 12 V power on when set to Y.
•
See Figure 9 and Table 1 for information on how to access the 12 Vdc power and its capability rating.
•
If the Turn on the 12 V power setting is set to Y, then you are prompted to enter the following setting:
