3.SETUP
AC Power
This fixture runs on 100~240 VAC, 50/60 Hz. Before powering on the unit, make sure the line voltage
to which you are connecting it is within the range of accepted voltages.
Always connect the fixture to a switched circuit. Never connect the fixture to a rheostat
(variable resistor) or dimmer circuit, even if the rheostat or dimmer channel is used only as a 0
to 100% switch.
To determine the power requirements for a particular fixture, see the label affixed to the back plate of
the fixture or refer to the fixture’s specifications chart. A fixture’s listed current rating indicates its
average current draw under normal conditions.
Always connect the fixture to a circuit with a suitable electrical ground.
Power Linking
This fixture contains power linking via the edison outlet located in front of the power input cable.
Please see the diagram below for further explanation.
The maximum quantity of fixtures that may be linked is 16.

Rigging
Be sure that the structure can support the weight of the fixture. Please see the “Technical
Specifications” section of this manual for a detailed weight listing. Mount the fixture securely. This
may be done with a screw, nut and bolt, or a hanging clamp. The hole in each bracket is 13 mm in
size. When rigging consider routine maintenance and control panel access. Please see the following
steps for installation.
•Be sure to orient the gel frame release so that it is pointing up. Please see the diagram
below for a visual reference.
•If the power link out is intended to be used with multiple fixture, take into account the length
of each power cable, and mount the fixtures close enough to one another to accommodate
for this.
•When aiming the fixtures, you may use the bracket adjustment knob. Loosen the knob,
adjust to the desired angle, and then tighten the knob by turning clockwise. Do not use
tools for this step, as it may cause damage.
•There is a secondary portion of the bracket, which may be used primarily for floor standing
positions.
•Safety cables must always be used.

LED PAR 38-Tri B&C User Manual 9 Rev. 2
Fixture Linking
You will need a serial data link to run light shows of one or more fixtures using a DMX controller or to
run synchronized shows on two or more fixtures set to a master/slave operating mode. The combined
number of channels required by all the fixtures on a serial data link determines the number of fixtures
the data link can support.
Fixtures on a serial data link must be daisy chained in one single line. To comply with the EIA-
485 standard, no more than 32 fixtures should be connected on one data link. Connecting
more than 32 fixtures on one serial data link without the use of a DMX optically-isolated
splitter may result in deterioration of the digital DMX signal.
Maximum recommended serial data link distance: 500 m (1640 ft)
Maximum recommended number of fixtures on a serial data link: 32
Data Cabling
To link fixtures together you must obtain data cables. You can purchase CHAUVET certified DMX
cables directly from a dealer/distributor or construct your own cable. If you choose to create your own
cable please use data-grade cables that can carry a high quality signal and are less prone to
electromagnetic interference.
4. OPERATING INSTRUCTIONS
Configuring the Starting Address
Each fixture requires a starting address from 1~512. A fixture requiring one or more channels for
control begins to read the data on the channel indicated by the starting address. For example, a
fixture that uses seven DMX channels and is addressed to start on DMX channel 100, will read data
from channels: 100, 101, 102, 103, 104, 105 and 106. Choose the starting addresses for each fixture
so that the channels used do not overlap. In addition, you should note the starting address selected
for future reference.
The LED PAR 38 Tri-B/Cfixture uses seven or three DMX channels. If this is your first time using
DMX, we recommend reading the “DMX Primer” section in the “Appendix”.

5.APPENDIX
General Maintenance
To maintain optimum performance and minimize wear, fixtures should be cleaned frequently. Usage
and environment are contributing factors in determining frequency. As a general rule, fixtures should
be cleaned at least twice a month. Dust build up reduces light output performance and can cause
overheating. This can lead to reduced lamp life and increased mechanical wear. Be sure to power off
fixture before conducting maintenance.
•Unplug fixture from power.
•Use a vacuum or air compressor and a soft brush to remove dust collected on external
vents.
•Clean all glass when the fixture is cold with a mild solution of glass cleaner or Isopropyl
Alcohol and a soft lint free cotton cloth or lens tissue.
•Apply solution to the cloth or tissue and drag dirt and grime to the outside of the lens.
•Gently polish optical surfaces until they are free of haze and lint.
The cleaning of external optical lenses and/or mirrors 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 surroundings can cause greater accumulation of dirt on the unit’s optics. Clean
with soft cloth using normal glass cleaning fluid. Clean the external optics at least every 20 days.
Clean the fixture at least every 30/60 days.
Always dry the parts carefully after cleaning them.
Never spin a fan using compressed air.
Setting the Starting Address
This DMX mode enables the use of a universal DMX controller device. Each fixture requires a start
address from 1~512. A fixture requiring one or more channels for control begins to read the data on
the channel indicated by the start address. For example, a fixture that uses six DMX channels and
was addressed to start on DMX channel 100, would read data from channels: 100, 101, 102, 103,
104, and 105. Choose start addresses so that the channels used do not overlap, and note the start
address selected for future reference. If you are unfamiliar with DMX, download the DMX Primer from
www.chauvetlighting.com.
