Troubleshooting
Following
are
a
few
common
problems
that
may
occur
during
operation.
Here
are
some
suggestions
for
easy
troubleshooting:
A.
The
unit
does
not
work,
no
light
and
the
fan
does
not
work
1.
Check
the
connection
of
power
and
main
fuse.
2.
Measure
the
mains
voltage
on
the
main
connector.
3.
Check
the
power
on
LED.
B.
Not
responding
to
DMX
controller
1.
DMX
LED
should
be
on.
If
not,
check
DMX
connectors
and
cables
to
see
if
link
properly.
2.
If
the
DMX
LED
is
on
and
no
response
to
the
channel,
check
the
address
settings
and
DMX
polarity.
3.
If
you
have
intermittent
DMX
signal
problems,
check
the
pins
on
connectors
or
on
PCB
of
the
unit
or
the
previous
one.
4.
Try
to
use
another
DMX
controller.
5.
Check
if
the
DMX
cables
run
near
or
run
alongside
to
high
voltage
cables
that
may
cause
damage
or
interference
to
DMX
interface
circuit.
C.
One
of
the
channels
is
not
working
well
1.
The
stepper
motor
might
be
damaged
or
the
cable
connected
to
the
PCB
is
broken.
2.
The
motor’s
drive
IC
on
the
PCB
might
be
out
of
condition.
6.
Fixture
Cleaning
The
cleaning
must
be
carried
out
periodically
to
optimize
light
output.
Cleaning
frequency
depends
on
the
environment
in
which
the
fixture
operates:
damp,
smoky
or
particularly
dirty
surrounding
can
cause
greater
accumulation
of
dirt
on
the
unit’s
optics.
Clean
with
soft
cloth
using
normal
glass
cleaning
fluid.
Always
dry
the
parts
carefully.
Clean
the
external
optics
at
least
every
30
days.
