and fixing (bolts, clamps, etc…) are rated to
support the weight of the fixture.
4.2 Safety chain
When hanging LEDko EXT FullSpectrum it is recommended to use a safety chain, as required
by current legislation. The safety chain must pass through the handles of the unit and then
attached to the structure.
If using steel cables and chains not Coemar’s production, make sure they are suitable to support
the weight of the unit according to normative UL/ETL (required: the weight of 6 complete
devices for at least one hour).

4.4 Optical group and framing system
Follow these steps in order to configure the optical group properly:
1. Remove the two screws “C” placed on both sides of the optical holder tube;
2. Gently remove the optical holder tube “D” pulling it away from the body;
3. Loose the thumbscrews “E” of the two lenses to set them at desired position. Turn on the fixture
and check if the desired focus and zoom lever are correct, then tighten the thumbscrews;
4.3 Adjusting unit’s tilt
1. In order to adjust the tilt of the unit simply loose the side screw “B” on the yoke, adjust the tilt
and lock the yoke by tightening the screw again.

4.5 How to remove the ‘Dual gobo rotator’
When you will receive LEDko EXT, the dual gobo rotator will already be installed in the projector
”F”; then follow the instructions below to remove it:
Once the optical tube holder has been removed, disconnect the plug that connect the motors
to the LEDko EXT body, unscrew the screws “G”, pull the dual gobo rotator up by one/two
centimeters, incline it “H” until it can be removed from the opticl group
4.6 How to mount the four blade framing system
Once the dual gobo rotator has been removed, the four blade framing system can be inserted.
Incline the four blade framing system “I”, insert it into the optic group, place it in the appropriate
slot and screw the previously unscrewed screws “J”.

4.7 How to insert the glass gobos
To insert one or two (glass or metal) gobo, follow the 4.5 paragraph to remove the dual
gobo rotator; then screw off the metal rings “K” that will keep the gobo steady with the
provided key “L”, follow the same steps if you want to mount a second gobo on the back.
Once removed one or both the rings, place your gobo “M” at will. Done this, proceed
with the re-closing the dual gobo rotator. Then place the rings in the appropriate slot and
re-tighten until the gobo is well fixed. At this point reinsert the dual gobo rotator keeping it
slightly inclined “N” so that it can enter in the optical group and fix it in the slot. Finally reconnect
the plug that goes from the motors of the dual gobo rotator to the body of the LEDko EXT. At
this point following the DMX chart you should be able to move your gobo at your convenience.

5. Powering up
5.2 Connection to mains power
Mains cable characteristics
The mains cable provided is thermally resistant, complying to the most recent International
standards.
Note: in case of cable replacement, similar cable with comparable thermal resistant qualities
must be used exclusively (cable 3 X 1,5 ø external 10 mm, rated 300/500V, tested to 2 KV,
operating temperature -40°C + 180°C, Coemar cod. CV5311).
Connection to mains power
LEDko EXT FullSpectrum is equipped with two power connectors, one as input and one as
output, which can be used to feed up to 8 (at 230 VAC) or 4 (90 VAC) fixtures.
The max absorption of LEDko EXT FullSpectrum is reported in the following table:
- 230 VaC 0.93 A constant during normal exercise.
- 90 VaC 2.38 A constant during normal exercise.
5.1 Operating voltage and frequency

Warning!!
•The use of a thermal/magnetic circuit breaker is recommended. Strict adherence to
regulatory norms is strongly recommended.
•LEDko EXT FullSpectrum should not be powered through a dimmer as this may
damage the internal switching power supply.
•Prior to connecting the device to mains power, ensure that the mains characteristics are
within the recommended range for the use of LEDko EXT FullSpectrum.
•All cabling and connections should be carried out by a suitably qualified personnel.
Warning!
Make sure that screening and conductors are not in contact one another or with the
metal housing of the connector.
Pin#1 and housing never must be connected to the power supply unit.
6.1 Control signal connection by XLR5 plugs
The digital control signal is transmitted to the projector via a two pole cable screened as per
International standards for the transmission of DMX 512 data. The connection must be serial,
using connectors XL5 male and female located on the back of LEDko EXT FullSpectrum
labelled DMX512 IN e OUT (see diagram).
Connectors equipped on LEDko EXT are IP rated, which ensures protection against water and
dust. In order to keep this rating they must be connected exclusively to other IP rated connectors.

7. Turning on the projector
After having followed the preceding steps described, proceed with the power supply and turn
on the projector connecting it to the mains power.
The software version installed on the internal microprocessors will be shown on the display,
suddenly it will show the current DMX addressing. If the address blinks, it means that the DMX
signal has not been received. Check the connection cable and the mixer functioning.
7.1 DMX address of the unit
Each projector can use 17, 11, 7, 4 or 10 address channels for its complete operation and is
controlled by a DMX 512 signal.
DMX addressing
When powered up initially, each projector will show A001, which indicates DMX address
001; for example, when set at 17 channels a projector thus addressed will respond to com-
mands of channel 1 to 17 from your DMX 512 controller. A second unit must be addressed as
A018, a third one as A035 and so on. The operation must be carried out on every LEDko EXT
FullSpectrum which has an address different from A001.
Altering the DMX address:
1. Press the + or – button until the display shows the required DMX address. The digits on the
display will blink to indicate that the variation has not been registered.
2. Press the enter key to confirm your selection. The digits on the display panel will cease to blink
and the projector will now respond to the new address.
Note: by holding the + or – button down the scrolling will be faster; thus allowing a faster selection
Warning!
If you alter the DMX address with no DMX signal connected, the digits on the display
panel will continue to flash even after you have pressed ENTER button to confirm the
address.
