3 Safety
3.1 Basic Safety Instructions
The following safety instructions have fundamental importance for the use of the
laser marking device, and for its care and maintenance.
They must always be followed and are only stated centrally here.
Functional safety In order to realise functional safety, the laser marking devices of ACI product groups,
Business Diode GN und Business Diode UV, contain the safety module, "laser safety
device” (hereinafter also referred to as SD). It is classed in category 3 and achieves per-
formance level (PL) e according to the DIN EN ISO 13849-1 standard.
Characteristics according to DIN EN ISO 13849-1:
Performance Level: e
Category: 3
MTTFd: > 67 years
DCavg: mean (90% - 99%)
Based on the useful life of the shutter module (swivelling diaphragm), this module must be
replaced after 14 years, at the latest, in order to maintain performance level e.
Laser class As an OEM component, the DPL Nobilis Marker and the DPL Lexis Marker are class 4
laser marking devices according to DIN EN 60825-1 "Safety of Laser Devices".
•The accessible laser radiation is very dangerous to the eyes and skin.
•Even diffuse, scattered laser radiation can be dangerous if the accessible radiation ex-
ceeds the class 1 threshold.
•Improperly used laser radiation may lead to a risk of fire or explosion.

Safety
14
The following measures must be taken in order to be able to categorise the DPL Nobilis
Marker and the DPL Lexis Marker as a class 1 laser device (accessible laser radiation is
harmless):
•Ensure that the entire beam path to the work piece is shielded beam-tight.
•Those parts of the screening which can be removed without tools must be fitted with
safety switches which interrupt the beam path before the laser beam leaves the device.
•Viewing windows (e.g. in the enclosure or the screening) must be fitted with laser pro-
tection glass appropriate for the wavelength and the laser power class.
The guidelines stated in DIN EN 60825-4 "Safety of Laser Devices" and DGUV no. 11 "La-
ser Radiation" must be implemented if the accessible laser radiation cannot be reduced
to below the class 1 threshold values when the device is integrated into the installation.
Emissions •If the design of the installation prevents the requirements for class 1 laser devices being
fulfilled, the area around the laser system must be protected by
- adjustable walls,
- light signals and
- warning notices
so that adequate notice is given of the danger before the area is entered.
•Install a second emission warning light in the view of the operator. During operation,
this signals that the beam catcher (shutter) arranged in the laser beam path is open.
The shutter consists of a screen which can be swivelled into the beam path, so inter-
rupting the laser process.
•Chemical and physical reactions during the laser marking can cause
- gases,
- vapours,
- aerosols,
-dusts,

Safety
15
-mistsor
- other reaction products
to be given off from the material surface.
These may be toxic, depending upon the material being processed. The operating
company must therefore provide effective extraction. Information about this can be
found, for example, in the VDI guideline 2262 1...3 "Air Quality in the Work Place".
•Please contact the manufacturer with regard to relevant accessories and protective
equipment.

Safety
16
General •Read the operating instructions and always keep them in an accessible place.
•Do not mark any easily flammable or combustible materials.
•Do not transport, store or operate the device in a vertical position.
There is a risk of damaging optical components.
Initial start-up •The ambient temperature must lie within the range of > 20 °C and < 30 °C. The con-
densation temperature as a function of the momentary relative air humidity must be
< 20 °C. You will find an instruction for estimating the momentary value in the appendix.
•Ensure that the relative air humidity does not exceed 85%.
•Never start the device immediately after large temperature changes. Condensation wa-
ter may damage the device.
•Ensure that an adequate air supply can be provided at the location of the supply unit

Safety
17
and that none of the vents are covered.
The vents must be clear and free of any residual packing material.
•Mount the device at the installation site in accordance with the regulations.
•Ensure that the shutter is active (closed) during the set up.
The main beam is simulated by a pilot laser.
The laser is not harmful to the skin. The eyes are protected by the natural blink reflex.
Operation •The laser marking device may only be operated by trained personnel.
It is advisable to log both the initial training as well as the regular refresher courses.
•The device may only be operated when connected to an alternating voltage supply cor-
responding to the specifications on the type plate.
•The effectiveness of the protective conductor must be regularly checked and confirmed
by an authorised skilled worker.
•If a defect occurs in the laser marking device, it must be disconnected from the power
supply system and secured against being switched on again.
Maintenance/Care •Maintenance and repair work on the laser device may only be performed by the man-
ufacturer.
•The device must be disconnected from the power supply system before the covers are
removed.
•Do not touch the electrical/electronic components. Capacitors could still be charged
and so be under voltage.

Safety

3.2 Labels at the Device
Warning notices The warning notices on the device point out possible hazards from the laser and provide
information about the basic performance data of the laser units.
