To optimize the performance of this product, please read these operating
instructions carefully to familiarize yourself with the basic operations of
this unit. These instructions contain important safety information regard-
ing the use and maintenance of this unit. Please keep this manual with
the unit, for future reference.
Accu Scan 250™ General Instructions
This unit emits intense UV radiation which is harmful to the eyes and
skin. The intense luminance of the lamp can cause severe damage
to the retina. Never operate this unit without it’s covers, these covers
have been specially designed to shield against UV radiation.
Epileptic Warning: Those suffering from epilepsy should avoid looking
directly into the lamp at all times.
Avoid switching the fixture on and off repeatedly in short intervals as
this will reduce lamp life and intensity.
To achieve the intensity associated with discharge lamps, these lamps
use gas sealed in a high pressure environment to emit a brilliant output.
Due to the high pressure involved with the construction of the lamp,
the lamp may explode during prolonged extensive use. This risk is
increased with age, added care is encouraged when dealing with older
lamps. Extreme caution should be used when operating this or any
fixture fitted with a gas discharge lamp. Never open this unit while in
use.
Caution! There are no user serviceable parts inside this unit. Do not
attempt any repairs yourself, doing so will void your manufactures
warranty. In the unlikely event your unit may require service please
contact American DJ®.
During operation the housing may become extremely hot. Avoid
touching the unit with bare hands while in use.
American DJ® will not accept any liability for any resulting damages
caused by the non-observance of this manual or any unauthorized
modification to this unit.

Power Supply: Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ®
Accu Scan 250.™ The American DJ® Accu Scan 250™ is available in
a 120v and 220v version. Because line voltage may vary from venue
to venue, you should be sure your unit voltage matches the wall outlet
voltage before attempting to operate you fixture. Also be sure to only
use the included I.E.C. power cable supplied with the unit, this cable
matches the voltage and current requirements of the unit.
DMX-512: DMX is short for Digital Multiplex. This is a universal pro-
tocol used by most lighting and controller manufactures as a form of
communication between intelligent fixtures and controllers. A DMX
controller sends DMX data instructions from the controller to the fix-
ture. DMX data is sent as serial data that travels from fixture to fixture
via the DATA “IN” and DATA “OUT” XLR terminals located on all DMX
fixtures (most controllers only have a DATA “OUT” terminal).
DMX Linking: DMX is a language allowing all makes and models
of different manufactures to be linked together and operate from a
single controller, as long as all fixtures and the controller are DMX
compliant. To ensure proper DMX data transmission, when using
several DMX fixtures try to use the shortest cable path possible. The
order in which fixtures are connected in a DMX line does not influence
the DMX addressing. For example; a fixture assigned a DMX address
of 1 may be placed anywhere in a DMX line, at the beginning, at the
end, or anywhere in the middle. Therefore, the first fixture controlled
by the controller could be the last fixture in the chain. When a fixture
is assigned a DMX address of 1, the DMX controller knows to send
DATA assigned to address 1 to that unit, no matter where it is located
in the DMX chain.
Data Cable (DMX Cable) Requirements (For DMX
and Master/Slave Operation): The Accu Scan
250™ can be controlled via DMX-512 protocol.
The Accu Scan 250™ is a eight channel DMX unit.
The DMX address is set electronically using the
controls on the side panel of the unit. Your unit and
your DMX controller require a standard 3-pin XLR
connector for data input and data output (Figure
Accu Scan 250™ Set Up
Figure 1

1). If you are making your own cables, be sure to use standard two
conductor shielded cable (This cable may be purchased at almost all
professional sound and lighting stores). Your cables should be made
with a male and female XLR connector on either end of the cable. Also
remember that DMX cable must be daisy chained and cannot be split.
American DJ® - www.americandj.com - Accu Scan 250™ Instruction Manual Page 11
Accu Scan 250™ Set Up
Notice: Be sure to follow figures two and three when making your own
cables. Do not use the ground lug on the XLR connector. Do not con-
nect the cable’s shield conductor to the ground lug or allow the shield
conductor to come in contact with the XLR’s outer casing. Grounding
the shield could cause a short circuit and erratic behavior.

Special Note: Line Termination. When longer runs of cable are
used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 90-120 ohm 1/4 watt resistor which is con-
nected between pins 2 and 3 of a male XLR connector (DATA + and
DATA -). This unit is inserted in the female XLR connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number Z-DMX/T) will decrease the possibilities of erratic
behavior.

Optimizing Lamp Alignment: This procedure centers the lamp in
the reflector. Proper optimization will increase lamp life and ensure a
bright crisp output. Improper optimization may add a yellow tint to the
lamp output and reduce intensity.
1. Be sure main power is disconnected and allow the unit to cool. If
the you have just installed a new unit you can obviously skip this
step.
2. Make a preliminary adjustment: Turn the three lamp adjustment
thumb screws completely in (clockwise). Then back them each
out (counter-clockwise) about three complete turns.
3. Turn the unit on and allow it to reset.
4. Using either a DMX controller or the control panel on the unit,
strike the lamp and focus the light on a flat surface. Please see
Spot on page 23.
6. Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws. Turn one screw at a time to drag the hot-spot
diagonally across the projected image. If you cannot detect a hot-
spot, adjust the lamp until the light is even.
7. To reduce a hot-spot, pull the lamp in by turning all three screws
clockwise 1/4-turn at a time until the light is evenly distributed.
8. If the light is brighter around the edge than it is in the center, or if
light output is low, the lamp is too far back in the reflector. “Push”
the lamp out by turning the screws.

Accu Scan 250™ Cleaning
Accu Scan 250™ Trouble Shooting
Trouble Shooting: Listed below are a few common problems that
you may encounter, with solutions.
No light output from the unit;
1. Be sure you have connected your unit into a standard 120v wall
outlet.
2. Be sure the external fuse has not blown. The fuse is located on
the bottom panel of the unit.
3. Remove the lamp holder and be sure the lamp is seated in its
socket properly. Occasionally lamps become loose during ship-
ping be sure the lamp is push in to its socket all the way.
4. Be sure the fuse holder is completely and properly seated.
Unit does not respond to sound;
1. Low frequencies (bass) should cause the unit to react to sound.
Tapping on the microphone, quiet or high pitched sounds may
not activate the unit.
Fixture Cleaning: Due to fog residue, smoke, and dust cleaning the
internal and external optical lenses and mirror should be carried out
periodically to optimize light output. Cleaning frequency depends on
the environment in which the fixture operates (I.e. smoke, fog residue,
dust, dew). In heavy club use we recommend cleaning on a monthly
basis. Periodic cleaning will ensure longevity, and crisp output.
1. Use normal glass cleaner and a soft cloth to wipe down the out-
side casing.
2. Use a brush to wipe down the cooling vents and fan grill.
3. Clean the external optics and mirror with glass cleaner and a soft
cloth every 20 days.
4. Clean the internal optics with glass cleaner and a soft cloth every
30-60 days.
5. Always be sure to dry all parts completely before plugging the unit
back in.
