1.6.3 Heat dissipation
See also chapter 3.1.5
• All laser power supplies are water-cooled, except those for the SLS 200 CL16 and the DLS.
They are air-cooled.
• An industrial or drinking water supply is required for the water cooling.
• The air-cooled devices give off their heat into the surroundings.
• The water-cooled devices also give off a little of their heat into the room.
• At temperatures below 3°C the lasers cannot be switched because of the risk of
frozen cooling water.
The following applies to all devices:
• Ambient temperature (operation) 10...35°C (average over 24 h) max. 40°C
• Ambient temperature (storage) 5...40°C
• Max. rel. humidity 80%
• Max. noise level 65 dBA, at a distance of 1 m (SLS 200 CL16: 70 dBA)

See also chapter 3.1.6
• The fuse protection on the customer's premises must be in accordance with the table below.
• In order to comply, a safety cut-out switch with characteristic D curve (10..14xIn for max.
0.5..1.5 sec., in accordance with EN 60898) is recommended.
• In the event of failure of the safety cut-out all 3 phases must be disconnected from the mains simul-
taneously (all-phase switch-off)
• For optimum personal safety, the installation of a residual current circuit breaker with a sensitivity
of 300 mA is recommended on the customer's premises.
• The laser power supplies for the FLS series and the SLS 200 CL16 are suitable for connection to
50 Hz and 60 Hz mains power supplies.
• The laser power supplies of the KLS 246, SLS 200 and SLS 200CL series (except CL16) can be sup-
plied either for 50 Hz or 60 Hz mains power supplies.

that can even be selected with signals on USER1.
3 Input for switching off the laser. LOFF
In the event of external error conditions, e.g. in the CNC, the laser can be
switched off.
4 Output to indicate laser status. LSTAT0
This output is in addition to the OK output and can also be configured to be
the same.
USER 4A, optional, no 2-board NLS required, combination with USER 3B required.
• The two interfaces USER 3B and USER 4A give improved integration of the laser into a higher-order
machine.
• They allow the laser to be powered up or down via the SPS, without having to execute manual func-
tions or checks on the laser.
• The interlock key switch has a third position to allow it to switch over to local function if maintenance
work is required.
• In addition, there is also a message contact at the mushroom-shaped emergency-off button.
USER 5A, optional, 2-board NLS required
• This option provides a second opener contact at the mushroom-shaped emergency-off button.
(For those users who do not need the other functions of USER 4A).
USER 6A, multiple workstations, optional, 2-board NLS not required
• This interface provides the interlock and fiber-shutter signals that are needed when work is to be
done independently of one another with several fibers at several workstations.
• In this case, a workstation manager is required to ensure synchronisation of the individual worksta-
tions with the laser.
• This workstation manager is not part of the accessories supplied by LASAG lasers and must be cre-
ated by the integrator himself
USER 7A/8A, fast shutter, optional, 2-board NLS not required
• To drive the fast shutter, the two options of USER 7A (fast shutter only in the area of the interface plug)
and USER 8A (fast shutter and signals of USER 4A in the area A of the interface plug) are available.
• Attention: the drive of the fast shutter is not controlled by the laser control system, which is why
the integrator himself has to take care of the synchronisation between laser beam and fast shutter
movement.
• Key words: do not shoot onto the moving shutter, do not exceed the maximum closing time.

Pin assignment of options X52 and X53, max. number of plugs
• The USER1 interface on plug X51 is fitted as standard to every laser.
• The other optional interfaces are routed to the reserve plugs X52 and X53.
• Every plug has space for a signal group A and a signal group B.
• The signal groups can be combined as required.
• The number of plugs is limited.
• KLS 246 and SLS 200 have only one spare space, whereas the FLS N have two spare spaces.
• It should be noted that the option of an external operating panel (X54 OEM) requires a plug of this
type.
• The maximal possible number of plugs has to be checked all the time.

It can be used to switch the external cooling water and an external cooler.
5 Outputs for additional displays.
Laser warning lamp, beam blocking lamp, laser-on lamp.
X54 OEM, optional external operating panel
• With this option, the operating panel on the laser is dropped and is installed externally via this inter-
face, e.g. on the machine operating panel.
• The main switch remains on the laser, the mushroom-shaped Emergency-off button must be installed
at a suitable spot by the customer.
• It is recommended that the USER 4 interface (optional) is used to remotely switch on the laser.
COM1/2/3/4 serial interfaces
• The laser is operated and remotely controlled via the serial interfaces.
• Extensive access facilities to the internal system variables (for diagnostic purposes) are possible.
• For this reason, the serial interfaces are suitable primarily for connection of the LASAG operating
terminals and also for the remote diagnostics via modems.
• Two interfaces, COM1 and COM2, are available as standard, with COM2 normally being occupied by
an operating terminal.
• Two more interfaces, COM3 and COM4, are available as an option.
• A 24V power supply for the terminals is available on plug X61.
• The interfaces are PC compatible.

1.6.8 Operation
Operating devices
The following devices are available for operating
LASAG lasers:
• Hand-held operating device HT2
Enables access to all parameters and infor-
mation.
It is not possible to change the shape of a
laser pulse.
But its length and intensity can be changed.
• Built-in terminal ET1
Suitable only for VCPS power supplies (no
RTPS power supplies).
Enables access to all parameters and infor-
mation of a VCPS power supply.
• Built-in terminal ET2 (under development)
Enables access to all parameters and infor-
mation of all laser types. It is also possible to
change without restriction the pulse shape in
RTPS power supplies.
Operating program PCT1
Runs on a PC using Windows 95 and higher.
(at least 1 serial I/F). Same range of functions
and operating interface as ET1.
Operating program PCT2
Runs on a PC using Windows 95 and higher.
(at least Pentium 200 MHz, 1 serial I/F). Same
range of functions and operating interface as
ET2. In addition, a link to the LASAG applica-
tion database is possible.
User groups / Passwords
• It is possible with every operating device to define proprietary passwords for different user groups
(e.g. operator, expert, service engineer, etc.) and to specifically direct their competencies in this
way.
• This means that an operator without sufficient knowledge can be prevented from making illegal
changes to the manufacturing process.
