advisable to connect a DMX terminal.

7. TROUBLESHOOTING
You will find below a few common
problems that may occur during opera-
tion. Here are some suggestions to ease
the troubleshooting:
The fixture does not work, no light
• Check the connection to power and the
mains fuse.
• Measure the mains voltage on the
main connector.
Not responding to DMX controller
• DMX LED should be on. If not, check
DMX connectors and cables to see if
the units are linked correctly.
• If the DMX LED is on but there is no
response to the channel, check the
address settings and the DMX polarity.
• If you have intermittent DMX signal
problems, check the pins on the
connectors or on the PCB of the
fixture or the previous one.
• Try to use another DMX controller.
• Check if the DMX cables run near or
alongside high voltage cables that may
cause damage or interference to the
DMX interface circuit.
The device can’t slave to another one
• You may have a breakage in the DMX
cabling. Check the LEDs indicating
response to the master/ slave mode
signal.
• Check DMX address.
No response to the sound
• Make sure the fixture does not receive
any DMX signal.
• Check the microphone to see if it is
sensitive to sound by tapping lightly on
the microphone.
8. FIXTURE CLEANING
The cleaning of internal must be carried
out periodically to optimize light output.
Cleaning frequency depends on the envi-
ronment in which the fixture operates:
damp, smoky or particularly dirty
surrounding can cause greater accumu-
lation of dirt on the fixture’s optics.
• Clean with soft cloth using normal
glass cleaning fluid.
• Always dry the parts carefully.
• Clean the external optics at least
every 20 days. Clean the internal
optics at least every 30/60 days.
• If you are using a controller with a
5-pin DMX output, you need to use a 5
to 3 pin adapter-cable.
• Connect the fixtures together in a
“daisy chain” via XLR plug cables,
from the output of a fixture to the
input of the next fixture. The cable
cannot be branched or split to a “Y”
cable. Inadequate or damaged cables,
soldered joints or corroded connectors
can easily distort the signal and shut
down the system.
• The DMX output and input connectors
are pass-through to maintain the DMX
circuit when one of the units’ power is
disconnected.
• At the last fixture, the DMX cable has
to be terminated with a terminator
to reduce signal errors. Solder a
120-ohm 1/4W resistor between
pin 2 (DMX-) and pin 3 (DMX+) into
a 3-pin XLR-plug and plug it in the
DMX-output of the last fixture.
• Each lighting fixture needs to have an
address set to receive the data sent by
the controller. The address number is
comprised between 0-511 (usually 0 &
1 are equal to 1).
• 3-pin XLR connectors are more
common than 5-pin XLR ones.
• 3-pin XLR:
Pin 1: GND,
Pin 2: Negative signal (-),
Pin 3: Positive signal (+)
• 5-pin XLR:
Pin 1: GND,
Pin 2: Negative signal (-),
Pin 3: Positive signal (+),
Pin 4/5: not used
