Front Panel Pushbuttons
4.2.1
On/Test
Pressing this button simulates a utility power outage and causes BORIS to provide power
to the controller by deriving power from its internal batteries for 8 to 10 seconds. This self-
test verifies both the operation of the BORIS and the condition of the battery.
If BORIS passes the self-test, it returns to on-line operation. If BORIS fails the self-test,
it immediately returns to on-line operation and lights the replace battery LED. The loads
are not affected.
Charge battery overnight and perform self-test again. If replace battery LED is still on,
see Section 5 for information on replacing the battery.
When pressed, this button causes the BORIS on-battery audible alarm to be silenced.
When power returns, the alarm is reset so that it will sound during the next power outage.
This pushbutton has no effect on the low battery audible alarm, which sounds when 2
minutes of backup time remain.
4.2.2
Off
This pushbutton returns the unit to the “power-up” mode, which puts BORIS through the
self-test function, described in Section 3.2 of the “Operational/Test Instructions” section.

Power Meter
The 5-LED display on the left side of the BORIS unit shows power drawn from BORIS by
the load. The display indicates a percentage of BORIS rated capacity. If all five lights are
on, then the system should be checked for impending overload condition. See Section 6.
This example shows that the equipment powered by BORIS is drawing between 67% and
84% of rated capacity.
