4. Installation
Remove the frontal cap by loosening the upper and lower screws enough to free the cap itself,
set the optic’s flange tilted about 60°. Insert the optic’s flange into the body’s receptacle and
turn the optic 60° until it is firmly assembled to the projector body, free to rotate but not free to
detach itself from the body. Ensure the optic to the body by tightening the two screws previously
loosened.
4.1 Optical installation
Warning!!
When the protective cap is removed, never lean the fixture facing down.
The front lens can be seriously damaged.

12
4.2 Mechanical installation
LEDko VariWhite HD + may be hung from an appropriate structure in any position or on tripod.
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
A to support the weight of the fixture.
4.3 Safety chain
When hanging 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 ’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 Adjusting unit’s tilt
In order to adjust the tilt of the unit simply loose the side handle adjust the tilt and lock the yoke
by tightening the handle again.

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 VariWhite HD + is equipped with two power connectors, one as input and one as output,
which can be used to feed up to 8 (at 230 V) or 4 (at 115 V) fixtures.
The max absorption of LEDko VariWhite HD + is reported in the following table:
- 230 V 0.97 A constant during normal exercise.
- 115 V 1.95 A constant during normal exercise.
5.1 Operating voltage and frequency
The unit may operates at voltages ranges from 80 to 264 V at a frequency of 50 or 60 Hz. It is
not needed to eect any setup procedures: LEDko VariWhite HD + 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 VariWhite HD + 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 VariWhite HD +.
• 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 must never 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 in
according to the International standards for DMX 512 data transmission. The connection must
be serial, using connectors XLR5 male and female located on the back of LEDko VariWhite HD
+labelled DMX512 IN e OUT.

7. Turning the projector on
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 5, SUNRISE, RAW, 2or 1address 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 that the fixture
will start responding from the first DMX channel; LEDko VariWhite HD + also uses 5 DMX
channels, which means that it will respond to the commands from channel 1 to channel 5 of
your DMX 512 controller. Accordingly a second unit should be addressed as A006, a third one
as A011 and so on. The operation must be carried out on every LEDko VariWhite HD + which
has an address dierent 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 VariWhite HD +, 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 dierently 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 VariWhite HD + it is possible to quickly change the various
numbers displayed for the dierent 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.
