2.1.1 Laser Safety Class

The NOVOLAS Basic AT system itself is a Laser Class 4 laser system in accordance

with EN60825-1:2007. The emitted radiation (direct radiation and/or scattered

radiation) is partly invisible and can cause irreparable damage to the eye or skin

(warning labels – see chapter 9 ).

It is the responsibility of the system integrator to integrate the system such that no

hazardous laser radiation escapes from any part of the equipment. The entire

equipment must at least conform to Laser Class 2M in accordance with EN 60825-

1:2007.

2.2 Safety of the NOVOLAS Basic AT system

Only operate the NOVOLAS Basic AT system if all protective and safety devices - e.g.

removable guards, EMERGENCY STOP devices – are present and functional. It is in

the operating company's responsibility to install a laser warning lamp or other warning

device complying with EN60825-1 is installed prior to commissioning.

In the case of functional faults, switch off the NOVOLAS Basic AT immediately and

remove the mains plug. Have the fault corrected by an authorized specialist without

delay.

Carry out the setting-up, maintenance and inspection work as described in this

manual and observe the instructions on replacing parts. Repairs may only be carried

out by Leister Process Technologies or its authorized sales partners or certified

Particular hazards, which may arise from the NOVOLAS Basic AT, are described in

the following sections.

Version 2.1

09/2010 NOVOLAS Basic AT

Safety Instructions 9

2.2.1 Hazards from Laser Light

Laser diodes, as fitted in the NOVOLAS Basic AT, generate intense radiation in the

invisible, near infrared spectral range (800 – 1000 nm). Direct laser light and/or

scattered radiation can be hazardous to eyes and skin.

•

Laser light can reach your skin or eyes if the laser aperture and processing

area are not under a laser safety guard. Direct laser light and/or scattered

radiation can burn your skin or permanently damage your eyes.

•

Do not put your NOVOLAS Basic AT into operation until all safety measures

required in the standard EN60825-1 have been implemented.

•

For fiber-coupled laser modules: Never put the NOVOLAS Basic AT into

operation without having connected the optical fiber at both ends (Laser

module and processing optics).

•

Wear EN207/208 compliant laser protection goggles – eye protection for laser

radiation – when you disable the laser protection devices for repair work.

The most important protective measures when dealing with laser radiation are

contained in the standard EN60825-1 – Radiation safety of laser products.

An important aspect of the regulations is the division of laser devices into different

Laser Safety Classes, dependent on the hazard presented by the emitted light.

Leister Process Technologies’ NOVOLAS Basic AT conforms to Laser Class 4 on

delivery.

Laser Class 4

Laser Class 4 means that the direct and scattered radiation is hazardous to skin and

eyes. It can lead to burns and irreversible damage of eyes. The invisible radiation

from the NOVOLAS Basic AT high power lasers is assigned to Laser Class 4.

NOVOLAS Basic AT Version 2.1

09/2010

10 Safety Instructions

The NOVOLAS Basic AT must not be operated without additional protective guards or

alarmed danger zone. If this really is required, the relevant protective measures

(Laser protective goggles with adapted optical density for the wavelength range

described in EN 207/208, protective clothing etc.) must be implemented (see

EN60825-1).

•

Direct laser light and/or scattered radiation can burn your skin or permanently

damage your eyes.

•

Implement the necessary protective measures in the danger zone of the

NOVOLAS Basic AT in order to avoid exposure of eyes or skin from direct or

scattered radiation and to warn of hazards (also see the standard EN60825-

1).

•

Observe the statutory and local laws & regulations governing the operation of

laser products.

Laser Class 2M

The aiming laser, which is installed in the NOVOLAS Basic AT, belongs to Laser Class

2M (according to EN60825-1, wavelength 635-670nm, power ≤5 mW).

This laser radiation is generally harmless to the eye as the eyelid reflex prevents long

exposure. It is however not advisable to stare directly into the beam.
