This section explains the operation of the UPS
including the self diagnostic test, front panel
LEDs,
and
rear panel
user
controls.
Self
Diagnostic
Test
As the
unit
powers up, it conducts a self-
diagnostic test for about 5 seconds. During this
test, individual LEDs
turn
on
as various
parts
of
the UPS are checked.
If there is a problem, the LEDs above
and
below
the front panel icons
turn
on
to indicate
where
the problem is
and
an
audio alarm beeps twice.
Check section
6,
Troubleshooting Guide,
under
the specific icon for instructions.
At
the
end
of the self diagnostic test the audio
alarm will
sound
one short beep if no problems
are detected. To initiate a self test while the unit
is running, press
the
Alann
Silence/Reset
button for three seconds.
Front
Panel
Display
The front panels
of
all PowerRite Pro UPSs are
the same. Each front panel contains LEDs
above
and
below icons that indicate
how
the
UPS is functioning. The LEDs also give warning
about possible problems with the UPS's opera-
tion. The front panel also has
an
Alarm
Si-
lence
/Reset
button. Both the LEDs
and
the
Alann
Silence/Reset button are explained
in
the
following pages.
