Dangers caused by laser radiation
Due to the extreme concentration of the laserbeam, the whole energy of the radiation is concentrated in a very small area. If the laser beam hits a man, health damages can be caused. Next to burning the skin, laser beams can damage the human eye. According to the wavelength (colour) of the laser, the beam can penetrate into the retina and destroy it. Depending to the severety of the accident, dangers for the eyes have to be observed.
For a better understanding, a comparison with visible light may be helpful. A continuously emitting laser in the yellow/green sector with an optical power of only 1 mW (= 1.10-3 Watt) belongs to the relatively harmless classification 2. Staring into this beam already equals staring into the summer sun in central Europe. In this case, direct eye exposure is allowed for 0.25 s.
A laser product of the classification 3R has a 5 times higher optical power.
In contrast to sunlight or the light of an incadescent lamp where the optical power is quickly reduced with the distance, the natural reduction of a laser’s optical power is only minimal. THis is why health damages can also be produced if laser radiation hits a man in a larger distance. Due to the sharp concentration and the high optical power of laser products often used in discotheques, the laser beams can still produce health damages when reflected from e.g. glass surfaces or metallic surfaces.
Eye damage caused by unskilled operation of laser products can be treated as physical injury and persecuted by law.
Please note that the organizer is responsible for keeping to all specified protective measures. If a laser gets out of control, the event may need to be cancelled immediately.
If the organiser does not fulfill his safety duties, he is reliable by civil law for any damages occured, e.g.:
Pay the treatment costs of the damaged person.
Pay a smart money to the damaged person.
Economic damage caused can be demanded from the operator of the laser product.
Please note: EUROLITE cannot be made liable for damages caused by incorrect installations and unskilled operation!

Protective measures for a safe operation
For producing and operating with laser radiation the following regulation is binding: DIN EN 60825-1 “Sicherheit von Laser-Einrichtungen”, DIN 56912 “Showlaser und Showlaseranlagen”, Berufsgenossenschaftliche Vorschrift Laserstrahlung BGV B2, Merkblatt “Lasergeräte in Diskotheken und bei Show- Veranstaltungen”, Merkblatt “Disco-Laser”, all governmental regulation and all generally binding rules of technology.
The following are excerpts from the regulation mentioned above. The information basis corresponds with the date of printing. When operating a laser product in public or industrial areas, a series of safety instructions have to be followed that this manual can only give in part. The operator must therefore inform himself on the latest safety instructions and consider them.

Safety shutdown
Showlasers must provide a safety shutdown enabling to interrupt the laser radiation at any time by force. Mechanical construction The showlaser must be protected against adjustments, rotations and unintended movements. The showlaser must be installed in a way that the beam cannot emitted in an undesired way. The optical components must be firmly fixed at the wall etc. All holding elements must also be firmly fixed.

Audience area
In the audience area, the thresholds for radiation and radiation intensity must never be exceeded. Person must never be exposed to laser radiation higher than the highest allowed level. The operator has to make sure that laser radiation – also reflected laser radiation – higher than the highest allowed level is avoided by technical or organisational measures.

Showlaser area

• When operating showlasers, an area of danger is created, the so-called showlaser area in which the laser radiation may be higher than the highest allowed level. This area must never be reached by any unauthorized person.
• Depending on the intended show, the laser area must be kept as small as possible. There should only be persons in the laser area whose stay is absolutely necessary.
• The showlaser area must only be entered by trained and authorized persons. Suitable protective measures must be carried out.
• The geometric borders of the sholaser area must be calculated or measured before starting the operation.
• Laser radiation must only extend as far as necessary for the show. The beam must be limited by a diffuse surface, so that dangers due to indirect or diffuse reflections are minimized.
• There must not be any highly reflexible surfaces. If harmfull reflections occur nevertheless, they must be consired when defining the geometric borders.
• Laser products and any installations in the laser beam must be installed in a way the installations and the beampath cannot be moved unintended.
• Uncontrolled reflected radiation of laser products must be avoided, specular or reflexible objects or areas must be kept out of the laserbeam, must be removed or covered.
• In order to protect from dangerous reflections, tools, accessory and adjustment devices being used in the laser area should not have specular surfaces and people in the laser area should not wear specular objects.
• If several laser products are operated at the same tiem within one room, their beampaths must be shielded separately. If necessary, the beampath should only be accessible from one side, the optical axle should not be aimed at windows.
• The showlaser area must be safely shielded from the audience area, e.g. by a higher stage area or grids. The safety distance between the showlaser area and the audience area must be 1 m to the sides. The distance from the audience area to the top must be at least 3.5 m.
• If walls are used for shielding laser areas, walls e.g. made of brick, limestone or concrete are considered as suitable. Other shieldings may also be used if the comply with the requirement of DIN EN 12 254.

Control units

The control units of a showcases must lie outside the showlaser area and the complete showlaser area must be controllable from this point.
The laser product must only be accessible by authorized persons.
The showlaser must never be operated unattended!
During a show, the laser product must never be repaired or adjusted in a way that the laserbeam is corrected.

Outside the laser show, the beam must be interrupted closed to the laser or be shut off.

Operating staff

The laser-light-show must only be carried out by a trained person. This person must control the laserbeam during the show and immediately switch off the device or interrupt the laser beam in case of failure of the
device, unsecure operational conditions or unrest in the audience.
The operator has to make sure that hired persons operating laser products of the classification 2 to 4 are trained in their behaviour.
For showlasers, the operator has to instruct the hired persons on how to keep the accessible radiation as low as possible. The hired persons have to carry out these instructions.
At least once in a year, the operator has to make sure that the hired persons are informed upon the dangers of laser radiation, the existing safety installations and the necessary protective measures if laser products of the classification 2 to 4 are operated.
The operator has to make sure that only absolutely necessary hired persons can enter into the laser area.

Medical treatment of eye damage

Assuming that laser radiation has caused eye damage, the operator has to make sure that the hired person will immediately be treated by an eye doctor.

Unintended use/Behaviour in case of failure

This laser product must NEVER be operated by private persons as they cannot shield and control laser areas and as children may play with the laser product.
This laser product must NEVER be used at festivals, open-air events, parades etc. Outside operation is forbidden.
This laser must NEVER be operated, if it is not equipped with all protective measures for a safe operation.

CAUTION!
The use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure!

If the laser beam does not move after switching the device on, the device must immediately be taken out of operation. Please let the device be checked by a qualified service technician.
Laser products of the classification 2 to 4 must be installed in a way that unintended radiation is avoided. Unintended radiation is when laser radiation emits from the laser product without using the normal control elements, e.g. due to damaged isolation or interferences or if it is not avoided that control elements can be operated unintended.

INSTALLATION

This device is only allowed for an installation via the mounting bracket. In order to safeguard sufficient ventilation, leave 50 cm of free space around the device.
When choosing the installation-spot, please make sure that the device is not exposed to extreme heat, moisture or dust. There should not be any cables lying around. You endanger your own and the safety of others!
This device must never be operated or stockpiled in sourroundings where splash water, rain, moisture or fog may harm the device. Moisture or very high humidity can reduce the insulation and lead to mortal electrical shocks. When using smoke machines, make sure that the device is never exposed to the direct smoke jet and is installed in a distance of 0.5 meters between smoke machine and device. The room must only be saturated with an amount of smoke that the visibility will always be more than 10 meters.
Please note: Please define the audience area and the showlaser area before choosing the installation-spot.
The device has to be installed out of the reach of people.
Make sure that the area below the installation place is blocked when rigging, derigging or servicing the fixture.
Always fix the fixture with an appropriate safety bond.

Overhead installation/Rigging

DANGER TO LIFE!
Please consider the EN 60598-2-17and the respective national norms during the installation! The installation must only be carried out by an authorized dealer!
The installation of the device has to be built and constructed in a way that it can hold 10 times the weight for 1 hour without any harming deformation.
The installation must always be secured with a secondary safety attachment, e.g. an appropriate catch net. This secondary safety attachment must be constructed in a way that no part of the installation can fall down if the main attachment fails.
When rigging, derigging or servicing the device staying in the area below the installation place, on bridges, under high working places and other endangered areas is forbidden.
The operator has to make sure that safety-relating and machine-technical installations are approved by an expert before taking into operation for the first time and after changes before taking into operation another time.
The operator has to make sure that safety-relating and machine-technical installations are approved by an expert after every four year in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are approved by a skilled person once a year.

Procedure:

The device should be installed outside areas where persons may walk by or be seated.

IMPORTANT! OVERHEAD RIGGING REQUIRES EXTENSIVE EXPERIENCE, including (but not limited to) calculating working load limits, installation material being used, and periodic safety inspection of all installation material and the device. If you lack these qualifications, do not attempt the installation yourself, but instead use a professional structural rigger. Improper installation can result in bodily injury and or damage to property.
If the device shall be lowered from the ceiling or high joists, professional trussing systems have to be used. The device must never be fixed swinging freely in the room.

Caution: Devices in hanging installations may cause severe injuries when crashing down! If you have doubts concerning the safety of a possible installation, do NOT install the device!
Before rigging make sure that the installation area can hold a minimum point load of 10 times the device’s weight.
Mount the device to your trussing system using an appropriate clamp.
For overhead use, always install an appropriate safety bond.

You must only use safety bonds complying with DIN 56927, quick links complying with DIN 56926, shackles complying with DIN EN 1677-1 and BGV C1 carbines. The safety bonds, quick links, shackles and the carbines must be sufficiently dimensioned and used correctly in accordance with the latest industrial safety regulations (e. g. BGV C1, BGI 810-3).

Please note : for overhead rigging in public or industrial areas, a series of safety instructions have to be followed that this manual can only give in part. The operator must therefore inform himself on the current safety instructions and consider them.
The manufacturer cannot be made liable for damages caused by incorrect installations or insufficient safety precautions!
Pull the safety bond through the attachment eyelet and over the trussing system or a safe fixation spot. Insert the end in the quick link and tighten the safety screw.
The maximum drop distance must never exceed 20 cm.
A safety bond which already hold the strain of a crash or which is defective must not be used again.

Attachment at the wall/ceiling

Do only use appropriate screws and make sure that the screws are properly connected with the ground. 24/48 00026019.DOC, Version 1.2
The durability of the installation depends very much on the material used at the installation area (building material) such as wood, concrete, gas concrete, brick etc. This is why the fixing material must be chosen to suit the wall material. Always ask a specialist for the correct plug/screw combination indicating the maximum load and the building material.

Connection with the mains
Connect the connection cable of the power-unit with the DC IN-socket. Plug the power unit into your outlet. Showlasers must provide a manual safety shutdown enabling to interrupt the laser radiation at any time by force. If the laser product is installed in the trussing system or in an unaccessible location, it must at least be installed with a switchable power outlet.

DANGER TO LIFE!

Before taking into operation for the first time, the installation has to be approved by an expert!

Adjusting the laser

Switch the device on via the power switch.
Loosen the fixation screws of the hanging-bracket and adjust the laser product to the desired projection area.
Call up all desired projection patterns in order to make sure that the projections only move in the inaccessible showcase area.
Make sure that no mirrorballs, shining surfaces etc. are located in the laser beam. Shining objects must be
removed from the laser area or be covered.
Tighten the fixation screws of the hanging-bracket so that the laser beam cannot be moved without tools.

OPERATION

• With the POWER-switch, you can switch the device on and off.
• In the AUTO-mode, the patterns are run automatically. You can adjust the speed with the AUTO SPEEDcontrol.
• In the MUSIC-mode, the laser runs sound-controlled.
• In the MANUAL-mode, the desired pattern can be adjusted.
• Spatial effects of the projection patterns can be created by using a smoke-machine. Make sure that you do not use too much smoke so that the laser beam is swallowed after a short distance and the audience cannot see the projections.

CLEANING AND MAINTENANCE

• Laser products in discotheques are technical Lasereinrichtungen in Diskotheken sind technische working installations and fall under the Equipment Safety Act. This is why they must fulfill its requirements.
• The operator has to make sure that safety-relating and machine-technical installations are inspected by an expert after every four years in the course of an acceptance test.
• The operator has to make sure that safety-relating and machine-technical installations are inspected by a skilled person once a year.

The following points have to be considered during the inspection:

1. All screws used for installing the devices or parts of the device have to be tighly connected and must not be corroded.
2. There must not be any deformations on housings, fixations and installation spots (ceiling, suspension, trussing).
3. The electric power supply cables must not show any damages, material fatigue (e.g. porous cables) or sediments. Further instructions depending on the installation spot and usage have to be adhered by a skilled installer and any safety problems have to be removed.
   Always disconnect from the mains when the device is not in use or before cleaning it.
   We recommend a frequent cleaning of the device. Please use a soft lint-free and moistened cloth. Never use alcohol or solvents!
   Clean the front glass every two weeks from dust and smoke fluid residues.
   There are no servicable parts inside the device. Never open the housing! Maintenance and service operations are only to be carried out by authorized dealers.
   Should you need any spare parts, please use genuine parts.
   Should you have further questions, please contact your dealer.
