Fire prevention:
1. ProSpot 575 LX utilises a Philips 575 MSD or 575 MSR/2; the use of any alternative lamp is not recommended and will
null and void the fixture’s warranty.
2. Never locate the fixture on any flammable surface.
3. Minimum distance from flammable materials: 0,5 m.
4. Minimum distance from the closest illuminable surface: 2 m.
5. Replace any blown or damaged fuses only with those of identical values. Refer to the schematic diagram if there is any
doubt.
6. Connect the projector to mains power via a thermal magnetic circuit breaker.
prevention of electric shock:
1. High voltage is present in the internals of the unit. Isolate the projector from mains supply prior to performing any func-
tion which involves touching the internals of the unit, including lamp replacement.
2. For mains connection, adhere strictly to the guidelines outlined in section 7 of this manual.
3. The level of technology inherent in the ProSpot 575 LX requires the use of specialised personnel for all service applica-
tions; refer all work to your authorised coemar service centre.
4. A good earth connection is essential for proper functioning of the projector.
Never operate the unit without proper earth connection.
5. The fixture should never be located in an exposed position, or in areas of extreme humidity. A steady supply of circulating
air is essential.
Protection against ultraviolet radiation:
1. Never turn on the lamp if any of the lenses, filters, or the carbon fibre housing is damaged; their respective functions will
only operate efficiently if they are in perfect working order.
2. Never look directly into the lamp when it is operating.
Safety:
1. The projector should always be installed with bolts, clamps, and other fixings which are suitably rated to support the
weight of the unit.
2. Always use a secondary safety chain of a suitable rating to sustain the weight of the unit in case of the failure of the pri-
mary fixing point.

English

ProSpot 575 LX utilises a Philips 575 MSD or a Philips 575 MSR/2 lamp at 575 watts with a GX 9,5 lampbase. The lamp is
available from your authorised coemar sales agent.
The fixture’s internal temperature can reach 250° C after 5 minutes, with a maximum peak of 350° C; ensure that the lamp
is cold prior to attempting removal. The fixture should be allowed to stand and cool for 10 minutes prior to its removal.
MSR/SA lamps are part of the mercury vapour family of discharge lamps and must be handled with great care. The lamp
operates at high pressure, and the slight risk of explosion of the lamp exists if operated over its recommended life. We rec-
ommend, therefore, that the lamp be replaced within the manufacturer’s specified lamp life.
mounting the lamps
1) Using a Phillips head screwdriver, remove the screws (A) which hold the lampholder in place, located at the rear of the
projector head. 2) Remove the lampholder assembly (B).
3) Locate the lampholder (C)
Attention
Turn off the power prior to opening up the unit.

4) Insert the lamp.
The lamp used is manufactured from quartz glass and should be handled with care; always adhere to the instructions
supplied in the lamp’s packaging. Never touch the glass directly, use the tissue provided in the lamp’s packaging. The GX
9,5 lampbase is symmetrical in construction. DO NOT USE UNDUE FORCE. In case of difficulty, re-read the instructions
and repeat the procedure.
5) Replace the lamp assembly and replace and tighten the screws (A) which were previously removed.
Attention: we recommend that the lamp be realigned in the optical train of the unit to avoid overheating of the dichroic fil-
ters and other internal components of the unit. refer to section 13 for instructions about this procedure.

The projector may operate at voltages including 115-208, 230 or 240V .at 50 or 60 Hz; coemar presets (barring specific
requests) a voltage of 230v at a frequency of 50Hz.. The preset voltage is indicated on a sticker located on the base of the pro-
jector, as shown in the diagram.
If the operating voltage and frequency selected on the projector do not match those in use in the country in which you are
operating, follow the instructions located in section 17. Altering the operating voltage and frequency.
Incorrect voltage and frequency selection will detrimentally affect the operation of the projector.

mounting
ProSpot 575 LX may be either floor or ceiling mounted.
For floor mounting installations, the ProSpot 575 LX is provided with four rubber mounting feet.
For ceiling mounted installations we suggest the use of appropriate clamps or fixings to attach the fixture to the mounting sur-
face.
The structure from which the unit is hung should be of sufficient rating to hold the weight of the unit, as should any clamps used
to hang the unit. The structure should also be sufficiently rigid so as not to move or shake whilst the ProSpot 575 LX
moves during its operation.
2 mounting holes of Ø13 mm (A) are located on the base of the ProSpot 575 LX allowing for the connection of G-
clamps.
safety chain
We recommend the use of two safety chains (cod. 069) - connected to the ProSpot 575 LX and to the suspension truss in
order to avoid the fixture accidentally falling. If using an after-market safety chain not manufactured by coemar, ensure that
it is of sufficient rating to hold the weight of the unit.
You may attach the safety chain to the holes (B) located on the base of the fixture, as shown in the diagram below.
protection against liquids
The projector contains electric and electronic components which should under no circumstances come into contact with oil,
water, or any other liquid. The proper workings of the unit will be compromised should this occur.
movement
The projector has a maximum movement of 385° in the base and 260° in the yoke; DO NOT place any obstructions in the
path of the projector’s movement.
risk of fire
Each fixture produces heat and must be installed in a well-ventilated position. The minimum recommended distance from
flammable material is: 0.5m. Minimum distance from the object being illuminated is: 2 m.
forced ventilation
You will note on inspection that the fixture features various air inlets and cooling fans, located on both the base and head of
the fixture. these should, under no circumstances, be blocked or obstructed whilst the projector is in operation.
Doing so could cause the fixture to seriously overheat thereby compromising its proper operation.
ambient temperature
The projector should never be installed in locations lacking a constant flow of air. The ambient temperature should not
exceed 35°C.

norms, IEC 331,IEC 332 3C,CEI 20 35.
NB: In case of cable replacement, similar cable with comparable thermal resistant qualities must be used exclusively (cable 3x1.5
ø external 10 mm, rated 300/500V, tested to 2KV, operating temperature -40° +180°, coemar cod. CV5309).
mains connection
ProSpot 575 LX can operate at voltages from 208V-230V-240V at 50 or 60Hz (operating voltage and frequency can be
selected as described in section 5 of this manual).
Prior to connecting the unit to your mains supply, ensure that the model in your possession correctly matches the mains
supply available to you. For connection purposes, ensure your plug is of a suitable rating of 8 amps at 230V and 11 amps at
115V.
Locate the mains cable which exits the base of the unit and connect as shown below:
protection
The use of a thermal magnetic circuit breaker is recommended for each ProSpot 575 LX.

English

Control signal is digital, and is transmitted via two pair screened ø0.5mm cable.
Connection is serial, utilising XLR 3 male and female sockets located on the base of the ProSpot 575 LX, labeled DMX
512 In and OUT (see diagram).
Pin connections conform to the international standard:
pin 1= screening 0 volt
pin 2= data -
pin 3= data +
If using a controller which output signal via an XLR 5 (5 pin) socket, do not use pins 4 and 5, leaving them unconnected.
Ensure that all data conductors are isolated from one another and the metal housing of the connector.
Note: the housing of the cannon XLR 3 or 5 must be isolated.

After having followed the preceding steps, turn on the DMX 512 controller which will be used to control the ProSpot
575 LX. Following this, turn on the power to the projector, and turn on the projector’s power switch. The projector will
perform a reset function on all the internal and external motors. This will last some few seconds, after which it will be subject
to the external signal from the controller.
DMX led
The DMX led will be static on to indicate that DMX 512 signal is being correctly received by the projector.
If the led is off, the projector is not receiving signal. check the cabling and the functioning of the controller.

English

Each ProSpot 575 LX utilises 16 channels of DMX 512 for complete control. (for more details see paragraph 12. DMX
512 signal functions)
DMX coding
To ensure that each projector accesses the correct signal, it is necessary to correctly address each fixture. Any number
between 1 and 497 can be generated via the multifunction panel of the ProSpot 575 LX.
This procedure must be carried out on every ProSpot 575 LX. being used.
When powered up initially, each projector will show A001 which indicates DMX address 1; a projector thus addressed
will respond to commands on channel 1to 16 from DMX 512 controller. A second unit should be addresses as 17, a
third as 33 and so on until the final ProSpot 575 LX, has been addressed.
altering dmx addresses
1) Press the +or -button until the display shows the DMX required, the characters in the display panel will flash to indicate
that the selection is not stored in memory.
2) Press the enter button to confirm your selection; the display panel will cease to flash and the projector will now respond
to the new DMX 512 address.
3) To better understand the function of each channel, we refer you to section 12 “Control channel functions from a
DMX 512 controller”.
Important Note: Keeping the +or -button pressed will cause the display to alter at increased speed, allowing a faster
selection to be effected.
By pressing the –button, you may inadvertently select a DMX address which is not being communicated to the fixture by
the controller, for example 500. If this is the case, the display will slow the data reception, (since it does not exist), and you
will note that it is slow to respond to your commands (for example altering an address or requesting or confirming a reset).
You may solve this problem by either sending data to this address, or by altering the incorrect DMX setting of the ProSpot
575 LX. in question.

Aligning the lamp in the optical system is achieved via the 3 adjusters at the rear of the projector. This procedure should be
undertaken to properly align the lamp in the optical system and to avoid the possible overheating of the internal compo-
nents due to the incorrect focusing of the beam onto components not intended to be exposed to this.
alignment procedure
Alignment is effected via the 3 adjusters A, Band Coperating in conjunction with each other. The lamp should be on,
black-out and dimmer fully open, and no colour filters inserted.
If the lamp is not correctly aligned, a hot-spot will be noticeable. This is a function of the lamp’s positioning. Use the two
adjusters (Band C) to bring the hot-spot to the centre of the beam. Use the third adjuster (A) to flatten the beam to maxi-
mum uniformity.
vertical adjustment
Screw (C) acts on a lever and spring assembly to position the lamp via a horizontal movement within the reflector; rotate it
until correct positioning is achieved.
horizontal adjustment
Screw (B) acts on a lever and spring assembly to position the lamp via a horizontal movement within the reflector; rotate it
until correct positioning is achieved.
axial adjustment
Screw (A) moves the entire lamp assembly axially within the unit; rotate it until correct positioning is achieved, resulting in a
flat, even beam.

ProSpot 575 LX utilises a mechanical system which allows the fixture’s gobos to be removed without the need for spe-
cialised equipment.
Replacement gobos should be made of either heat resistant glass or metal.
An ever-increasing range of gobos is available from your coemar sales network.
replacing gobos
Gobo dimensions are as follows:
rotating gobo wheel
ø external = 32,9 mm
ø of image with defined edge = 28 mm
ø of image with undefined edge = 30 mm
thickness = from 0,2 to 3,5 mm
fixed gobo wheel
ø external = 32,9 mm
ø of image = 26 mm
thickness = from 0,2 to 3,5 mm
replacing gobos on the rotating gobo wheel
When replacing gobos as shown in the following diagrams, ensure that the projector is NOT powered up.
1- Open the projector housing as described in the section above, Opening up the projector housing
2- Loosen the screw as shown in the diagrams and move the metal leaf to allow easier access to the gobos
3) Release the gobo retaining spring and thereby carefully remove the gobo
4) Reverse the procedure to install a replacement gobo.
