Introduction
Please read these instructions carefully, which includes important
Safety Instructions
information about the installation, usage and maintenance?
Please keep this User Guide for future consultation. If you sell the unit to another user, be sure that they also receive this
instruction booklet.
Alw ays make sure that you are connecting to the proper voltage and that the line voltage you are connecting to is not higher
than that stated on decal or rear panel of the fixture.
This product is intended for indoor use only!
To prevent risk of fire or shock, do not expose fixture to rain or moisture. Make sure there are no flammable materials close
to the unit while operating.
The unit must be installed in a location with adequate ventilation, at least 50cm from adjacent surfaces. Be sure that no
ventilation slots are blocked.
Alw ays disconnect from power source before servicing or replacing lamp or fuse and be sure to replace w ith same lamp
source.
Secure fixture to fastening device using a safety chain. Never carry the fixture solely by its head. Use its carrying handles.
Maximum ambient temperature is Ta: 40℃. Do not operate fixture at temperatures higher than this.
In the event of serious operating problem, stop using the unit immediately. Never try to repair the unit by yourself. Repairs
carried out by unskilled people can lead to damage or malfunction. Please contact the nearest authorized technical assistance
center. Always use the same type spare parts.
Don’t connect the device to a dimmer pack.
Make sure power cord is never crimped or damaged.
Never disconnect pow er cord by pulling or tugging on the cord.
Avoid direct eye exposure to lamp. Gas discharge lamps generate UV radiation. Never operate the lamp without
appropriate protection as it could damage skin and eyes. These lamps operate at high pressures and there is always a slight
risk of tube rupture. The risk of rupture increases with age, temperature and improper handling of the lamp. These lamps
also generate UV radiation. The UV radiation that is emitted extends well below 287nm, which is considered the point at
which the UV radiation becomes imminently harmful. Exposure to this short wave UV should be limited. If aligning a
lamp, care must be taken to reduce the exposure time to the lamp. Never look directly at any lamp while it is powered on.
Read the booklet that accompanies each lamp and heed attention to the warnings concerning exposure to skin and eyes.
Use appropriate eye protection to block all UV rays. Do not use ordinary sunglasses.
Caution
There are no user serviceable parts inside the unit. Do not open the housing
or attempt any repairs yourself. In the unlikely event your unit may require
service, please contact your nearest dealer.

Before you Begin
Unpacking Instructions
Immediately upon receiving a fixture, carefully unpack the carton, check the contents to ensure that all parts are present, and have
been received in good condition. Notify the shipper immediately and retain packing material for inspection if any parts appear
damaged from shipping or the carton itself shows signs of mishandling. Save the carton and all packing materials. In the event that a
fixture must be returned to the factory, it is important that the fixture be returned in the original factory box and packing.
Mounting
The unit should be mounted via its mounting system
( as show n to the right ) on the bottom of the base.
Use clamps to fix the unit to truss. Alw ays ensure that
the unit is firmly fixed to avoid vibration and slipping
while operating. Always ensure that the structure to
which you are attaching the unit is secure and is able
to support a w eight of 30 kgs for each unit.
This fixture may be mounted in any position
provided there is adequate room for ventilation. It is
important never to obstruct the fan or vents pathway.
Mount the fixture using, preferably the center
mounting holes and a suitable “C” or “O” type
clamp. Adjust the angle of the fixture by loosening
both knobs and tilting the fixture. After finding the
desired position, retighten both knobs. When
selecting installation location, take into consideration
lamp replacement access and routine maintenance.
Safety cables should always be used. Never mount in
places where the fixture w ill be exposed to rain, high
humidity, extreme temperature changes or restricted
ventilation.
Powering
To determine the pow er 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 is its average current draw under normal conditions. All fixtures must be
pow ered directly off a sw itched circuit and cannot be run off a rheostat (variable resistor) or dimmer circuit, even if the rheostat or
dimmer channel is used solely for a 0% to 100% sw itch. Before applying power to a fixture, check that the source voltage matches the
fixture’s requirement. All fixtures must be connected to circuits with a suitable Earth Ground. Check the fixture or device carefully to
make sure that if a voltage selection switch exists that it is set to the correct line voltage you will use.

DMX-512 addressing
This mode enables the use of a universal DMX controller device. Each fixture requires a "start address" from 1 to 511. 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 occupies or uses 6 channels of DMX 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 notate the start address selected
for future reference. The Legend 250RX operates using 16 channels of DMX control.
If this is your first time addressing a fixture using the DMX-512 control protocol than I suggest jumping to the Appendix Section and
read the heading “DMX Primer”. It contains very useful information that will help you understand its use.
Upon pow ering up the unit, you will notice that it will display “AE16”. In addition, the fixtures electronics will load up its
programming and home (adjust) its motors to a starting position. The sequence of events should take no more than 20 seconds and it
is necessary for the fixture to operate correctly. During this time you will hear motor and mechanical movement inside the fixture.
After this initial power-up sequence, if the fixture receives no DMX signal, it w ill enter into a stand alone mode. Be sure to power up
your DMX controller device before the lighting fixture to avoid unwanted auto mode operation.
1. Press the MENU button until the display reads- .
2. Press the ENTER button to select DMX addressing. The selection is confirmed
when begins to blink. You must make a selection within 8 seconds.
3. Press the UP and DOWN buttons to increase or decrease values until the desired
value is achieved.
4. Press the ENTER button to activate selection.
Example Diagram: First 4 fixtures assigned.
NOTE! It is not necessary to turn the unit off when changing the DMX address.
Stand alone (master/slave) operation
By linking the units under a master/slave control mode, the first unit can direct additional units to create a sound activated,
synchronized light show. This is very useful for mobile DJs who want to setup and run a show quickly.
In this mode the fixture is assigned a master status and is indicated by the MASTER LED.
If the fixture is not connected to a controller then it will automatically enter a sound
activated state. You can adjust the mic sensitivity pod on the fixture for optimum sound
recognition.

DMX-512 connection
If you use a controller with a 5 pin DMX output connector, you will need to use a 5 to 3 pin adapter. Chauvet Model No: DMX5M
The last unit on the DMX chain should be terminated with a terminator. Solder a 120-ohm 1/4W resistor betw een pin 2(DMX-) and
pin 3(DMX+) into a 3-pin XLR-plug and plug it in the DMX-output of the last unit.
Connect the units together in a “daisy chain” fashion by connecting an XLR plug from the output of the unit to the input of the next
unit. The cable cannot be branched or split to a “Y” cable. DMX512 contains a high-speed signal. Inadequate or damaged cables,
soldered joints or corroded connectors can easily distort the signal and shut down the system.
Each lighting unit needs to have an address set to receive the data sent by the controller. Fixtures are addressable between 1 and 512.
Refer to Section 3.3 DMX addressing for further instructions.
XLR Configuration:
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 (+)

powering down to allow the unit cool down!
Because of its high internal pressure, there might be a risk that the Discharge lamp
could explode during operation. The lamp emits intense UV radiation which is
harmful to the eyes and skin. The high luminance of the arc can cause severe
damage to the retina if you look directly into the lamp source.
Alw ays switch off the main supply and never handle the lamp or luminaries w hen
it is hot.
Do not touch the bulb with bare hands. If this happens, clean the lamp with
alcohol and w ipe it with a lint free cloth before installation.
The lamp generates UV radiation. Never operate the lamp without appropriate
shielding.
When burning, the lamp operates at high pressure and there is a slight risk of arc
tube rupture. The risk increases w ith age, temperature and improper handling of
the lamp. Do not use the lamp any longer than its specified life.
Make sure the lamp is located in the
center of the reflector for the best spot.
Adjust lamp position by screws A, B
and C.

Appendix
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 and internal
components. Clean all glass w hen 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. Do not to touch the lamp glass when cleaning fixture. Oil and dirt can cause
damage and premature aging of the lamp. In the event that the lamp is touched or becomes dirty, clean the lamps with an alcohol
wipe.
DMX Primer
There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A fixture capable of receiving DMX
512 will require one or a number of sequential channels. The user must assign a starting address on the fixture that indicates the first
channel reserved in the controller. There are many different types of DMX controllable fixtures and they all may vary in the total
number of channels required. Choosing a start address should be planned in advance. Channels should never overlap. If they do, this
will result in erratic operation of the fixtures whose starting address is set incorrectly. You can however, control multiple fixtures of
the same type using the same starting address as long as the intended result is that of unison movement or operation. In other words,
the fixtures will be slaved together and all respond exactly the same.
DMX fixtures are designed to receive data through a serial Daisy Chain. A Daisy Chain connection is w here the DATA OUT of one
fixture connects to the DATA IN of the next fixture. The order in w hich the fixtures are connected is not important and has no
effect on how a controller communicates to each fixture. Use an order that provides for the easiest and most direct cabling. Connect
fixtures using shielded tw o conductor tw isted pair cable with three pin XLR male to female connectors. The shield connection is pin
1, while pin 2 is Data Negative (S-) and pin 3 is Data positive (S+). CHAUVET carries 3-pin XLR DMX compliant cables, DMX-10
(33’), DMX-4.5 (15’) and DMX-1.5 (5’)
Returns Procedure
Returned merchandise must be sent prepaid and in the original packing, call tags will not be issued. Package must be clearly labeled
with a Return Merchandise Authorization Number (RA #). Products returned without an RA # will be refused. Call CHAUVET and
request RA # prior to shipping the fixture. Be prepared to provide the model number, serial number and a brief description of the
cause for the return. Be sure to properly pack fixture, any shipping damage resulting from inadequate packaging is the customer’s
responsibility. CHAUVET reserves the right to use its own discretion to repair or replace product(s). As a suggestion, proper UPS
packing or double-boxing is alw ays a safe method to use.
Claims
Damage incurred in shipping is the responsibility of the shipper; therefore the damage must be reported to the carrier upon receipt of
merchandise. It is the customer's responsibility to notify and submit claims w ith the shipper in the event that a fixture is damaged due
to shipping. Any other claim for items such as missing component/part, damage not related to shipping, and concealed damage,
must be made within seven (7) days of receiving merchandise.
Fixture Cleaning
The cleaning of internal and 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 surrounding can cause greater
accumulation of dirt on the unit’s optics.
Clean with soft cloth u sing 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.
