4. Installation
4.1 Mechanical installation
LEDko EXT FullSpectrum may be hung from an appropriate structure in any position or
on tripode. If hanging the fixture from a lighting truss or similar, we recommend the use
of an appropriate clamp “A”, as shown in the following diagram.
Warning!!
Always ensure that your support structure
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, framing system and gobos
Follow these steps in order to configure the optical group properly:
1. Remove the two screws “A” placed on both sides of the optical holder tube;
2. Gently remove the optical holder tube “B” pulling it away from the body;
3. Loose the thumbscrews “C” 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
In order to adjust the tilt of the unit simply loose the side screw on the yoke, adjust the tilt
and lock the yoke by tightening the screw again.

4. It is possible to regulate the blades “D” to achieve the desired shape, use the
four thumbscrews “E” that you can see behind the blades to free or block them;
5. It is possible to use the gobos, to do so open the gobo holder, insert a normal gobo
or a glass gobo and close the gobo holder;
7. Reassemble the projector by pushing the optical holder tube on the optical group
and tighten the screws that has been removed at the beginning.
NB: When putting the screws, be careful not to tighten too much, otherwise it may
deform the base of the optical holder tube.
6. Use the hole that you can see above and under the pojector to lock the optical group’s
position, tighten the two screws symmetrically with each other in order to keep straight
your optical group;

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 0.80 A constant during normal exercise.
- 90 VaC 2,04 A constant during normal exercise.
5.1 Operating voltage and frequency
The unit may operates at voltages ranges from 90 to 230VaC at a frequency of 50 or
60 Hz. It is not needed to effect any setup procedures: LEDko EXT FullSpectrum
will automatically adjust its operation to suit any frequency or voltage within this range.

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 11, 8, 4, 1 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 11 channels a projector thus addressed will respond to
commands of channel 1 to 11 from your DMX 512 controller. A second unit must be
addressed as A012, a third one as A023 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.

9.1 Quick guide to menu
To access the functions menus just press the MENU button. Then press + or – buttons to
scroll the pages and press the ENTER button to access to any other function.
By suitably using all the functions of LEDko EXT FullSpectrum, which can be activated
through its display panel, it is possible to change some of the parameters and to add some
functions. Changing the preset settings made by Coemar can vary the functions of the
projector so that it will respond differently to the controller; therefore carefully read about
the functions described here before carrying out any possible selection.
9.2 Rapid count
Through the display panel of LEDko EXT FullSpectrum it is possible to quickly change the
various numbers displayed for the different functions in the following 3 manners:
1. Pressing the + or – buttons will cause the count to be quicker.
2. Pressing first + and then – and then holding them down simultaneously will cause the
numbers to jump to the highest value.
3. Pressing first – and then + and then holding them down simultaneously will cause the
number to jump to the lowest value.
