Operation Upon Loss of AC Power
The control is equipped with either an 8 Amp-Hour or 13
Amp-Hour 24 VDC lead acid battery for operation upon
loss of AC power. The control maintains full operation from
the battery for a period of time dependent upon the battery
size:
• 8 Amp-Hour — 12 hour maximum (20°C)
• 13 Amp-Hour — 24 hour maximum (20°C)
In the event that the AC power has not returned within the
times listed above, the control will disconnect the battery
from the circuit.
Note: The control continuously monitors the battery voltage. To
prevent battery damage, the control shuts down
automatically upon detection of low battery voltage
(below 22 VDC) for 60 seconds.
Control programming settings and parameters—including
event recorder—are stored in non-volatile memory and
retained upon loss of control power. The time/date clock
will continue to operate for approximately 30 days after
loss of control power.
Phase B (Ø) is the factory default phase. Unless changed
by the user, the B PHASE VOLTAGE red LED illuminates
indicating AC is the operating power. If BØ (or the user-
indicated phase) loses AC power, the ALARM red indicator
LED will illuminate. The ALARM log on the LCD Display will
indicate NO AC PRESENT and the CONTROL OK LED will
not be illuminated.
The control clock may require resetting if the operating
power has been disconnected for more than thirty days.
Refer to Service Information S280-70-4 (ProView 4.X.X) or
S280-70-21 (ProView 5.X.X) Form 6 Microprocessor-
Based Recloser Control Programming Guide for informa-
tion on setting the control clock.
Note: When AC power is present, the control will operate
regardless of back-up battery presence.

IMPORTANT: If the the control shuts down due to low
battery voltage before AC power is restored, and the
connected energized recloser is CLOSED; it will only
TRIP and LOCKOUT via front panel pushbutton
command.
A control that has shut down due to low battery voltage
before AC power is restored will have a blank LCD
display (no text message shown) and none of the LEDs
will be illuminated.
