3 Safety
The hardware described within this document is designed to control a laser scanner system. Laser radiation
may effect a person's health or may otherwise cause damage. Prior to installation and operation compliance
with all relevant safety regulations including additional hardware-controlled safety measures has to be
secured. The client shall solely be responsible to strictly comply with all applicable and relevant safety
regulations regarding installation and operation of the system at any time.
Beside of that some laser equipment can be damaged in case it is controlled with wrong signals or signals
outside a given specification. Thus it is highly recommended to check the output generated by this hardware
using e.g. an oscilloscope to avoid problems caused by wrong configurations. This should be done prior to
putting a system into operation for the first time, whenever some parameters have been changed or whenever
any kind of software update was installed.
The hardware described here is shipped without any cover and without prefabricated equipment for electric
installation. It is intended to be integrated in machines or other equipment. It is not a device for use "as is", but a
component which is intended to be used as part of a larger device, e.g. for integration in a machine with own
housing. Prior to operation compliance with all relevant electric / electromagnetic safety regulations including
additional hardware-controlled safety measures has to be secured. The client shall solely be responsible to
strictly comply with all applicable and relevant regulations regarding installation and operation of the system at
any time.
The EMC Directive (2014/30/EU) does not apply to this hardware as it is not intended for an end user (a person
without knowledge of EMC) and as it is not otherwise made available on the market.
The Low Voltage Directive (2014/35/EU) does not apply to this hardware as the voltage supply is below the
50V AC / 75V DC limit.
The scanhead described here is designed to deflect an input laser beam and output it again. It can't block or
weaken the laser beam. To prevent unwanted emission of the laser beam, above a particular danger class the
laser device must be fitted with a shutter or any other suitable device. This laser device must be of sufficient
quality so that the laser beam can only be emitted at the beam output on the deflection unit. Proper warning
signs have to be attached at the machine or device where this scanhead is used to clearly inform any user about
all possible dangerous operations.
The surfaces of the scanheads mirrors are extremely sensitive and should not be touched in any way and may
only be cleaned by experienced personnel. Thus we strongly recommend sending the deflection unit in to
HALaser Systems for the mirrors to be cleaned, as opening of the scanhead by unauthorized personnel voids
the warranty.
To improve the optical properties of the mirrors, lenses or protection glasses, different material are applied as
coatings. Some of them may be potentially hazardous to health if inhaled or swallowed. Under normal
circumstances, no special precautions are necessary when handling or storing mirrors, lenses or protection
glasses with such specific coatings.
In case of damage to such a component and/or coating, follow these instructions:
•
switch off the laser immediately
•
avoid inhaling dust of possibly broken or burned components
•
leave the room for at least 30 minutes
•
wear gloves and a mouth protector while performing all the subsequent steps
•
pack the optical elements in an airtight sealed plastic container, in case of fragments carefully collect up
all fragments
•
clean all contaminated components and surfaces with a damp cloth and pack the cleaning cloths in a
sealed plastic container too
•
ensure professional disposal of the container
Please note: these general instructions are relevant only in case special coatings are used on any of the optical
components. This includes also third party components which may be operated together with the HALscan
scanhead (like F-Theta lenses or protection glasses). For detailed information about the used coatings, their
dangerousness and for specific handling instructions in case of normal operation or damages, please contact
the supplier of the related components.
