Troubleshooting
The
following
are
common
methods
to
solving
Circuit
Troubles,
Ground
Fault,
Battery
and
Common
troubles.
Circuit
Trouble
Normally
when
a
circuit
trouble
occurs,
the
Trouble
LED
will
be
illuminated
and
the
common
trouble
relay
will
be
active.
Usually
a
relative
event
can
be
shown
on
the
LCD
event
list
view.
Use
these
indications
to
correct
the
fault,
check
for
open
wiring
on
that
particular
circuit
loop.

Ground
Fault
This
panel
has
ground
fault
detection.
To
correct
the
fault,
check
for
any
external
wiring
touching
the
chassis
or
other
Earth
Ground
connection.
The
maximum
resistance
for
testing
ground
fault
detection
for
extended
wirings
other
than
the
network
is
6.6
kohm.
The
maximum
resistance
for
testing
ground
fault
detection
for
network
wiringis
60
ohm.
Battery
Trouble
Check
for
the
presence
of
batteries
and
their
conditions.
Low
voltage
(below
20.4V)
will
cause
a
battery
trouble.
If
battery
trouble
condition
persists,
replace
batteries
as
soon
as
possible.
Common
Trouble
If
only
a
common
trouble
is
indicated
on
the
main
panel
and
none
of
those
above
confirming
trouble
indicators
are
on,
then
check
the
following
for
possible
fault
Any
missing
interconnection
wiring
Improperly
