A
VOLTAGE
CONTROL
:
Indicates
the
output
voltage
regulator
circuit
is
maintaining
voltage
regulation.
CURRENT
CONTROL
:
Indicates
the
output
current
regulator
circuit
is
maintaining
current
regulation.
HV
INHIBIT
:
Indicates
the
high
voltage
supply
is
being
inhibited
by
either
the
EXTERNAL
INHIBIT
signal
line
or
by
internal
protection
circuitry.
INTLK
CLOSED
:
Indicates
the
EXTERNAL
INTERLOCK
connections
are
in
the
closed
position.
INTLK
OPEN
:
Indicates
the
EXTERNAL
INTERLOCK
connections
are
in
the
open
position.
This
also
indicates
opening
of
internal
power
supply
interlocks.
It
is
not
possible
to
enable
high
voltage
with
an
open
EXTERNAL
INTERLOCK.
SYSTEM
FAULT
:
Indicates
an
internal
fault
has
occurred.
OVER
VOLTAGE
:
Indicates
the
overvoltage
protection
circuitry
has
caused
the
power
supply
to
turn
off.
The
default
setting
for
the
overvoltage
protection
circuitry
is
internally
set
to
105%
of
rated
output
voltage.
This
level
can
be
set
to
anywhere
from
0
‐
105%
of
rated
output
voltage
by
the
user
via
the
remote
overvoltage
programming
capability,
see
Chapter
3
for
more
details.
OVER
CURRENT
:
Indicates
the
output
current
has
exceeded
the
programmed
current
trip
level
when
the
AOL
(Adjustable
Overload
Trip)
feature
has
been
software
configured
using
the
digital
interface.
OVER
TEMP
:
Indicates
that
excessive
temperature
has
been
sensed
within
the
chassis
and
internal
protection
circuitry
has
shut
down
the
power
supply.
ARC
:
Indicates
that
an
arc
has
occurred
(one
second
flash)
or
that
the
ARC
Intervention
Circuitry
has
shut
down
the
power
supply
due
to
excessive
arcing
(latched
“ARC”
fault).
AC
FAULT
:
Indicates
a
problem
with
the
front
end
AC
input
circuitry
and
the
corresponding
generated
inverter
power
buss
voltages.
RGLT
ERR
:
Indicates
a
failure
in
the
voltage
or
current
regulation
circuitry.
This
fault
usually
occurs
when
there
is
a
lack
of
output
power
to
maintain
proper
regulation.
Possible
causes
could
be
due
to
low
AC
input
voltage
(below
low
line
parameters,
or
a
missing
phase)
or
a
malfunction
of
the
power
supply
preventing
it
from
generating
the
voltage/current
being
requested.
