In order to achieve optimal processing quality, it may
be necessary to fine-tune the working distance A. The
working distance A is defined as the distance
between the axis of the laser beam entering the scan
head and the nominal working plane – see figure 8.
Adjust the working distance A to the value provided
in the technical specifications on page 34.
The working distance A can be directly adjusted in
small steps. Alternatively, the working distance A can
also be adjusted indirectly via the beam divergence
–
this can be achieved with the help of a beam
expander or a variable focusing system (for example,
SCANLAB’s varioSCAN 20) placed in front of the scan
head’s entrance aperture.
5.4 Checking the Parameters of
Application Software
Before you start a laser application, you must care-
fully check your application software with regard to
the maximum allowed scan angle and working area.
If scan angles larger than the maximum allowed scan
angle indicated on page 34 are used, some
vignetting inside the scan head can occur and
damage to the interior of the scan head and the
objective might result. If your application requires
larger scan angles and a larger image field, then
contact SCANLAB for guidance.
5.5 Safe Start-up and Shutdown
Sequences
To assure safety during start-up, proceed exactly as
follows:
(1) Turn on the controlling PC containing the RTC
®
PC interface board and start up the control
software (or alternatively switch on the
RTC
®
SCANalone standalone board).
(2) Turn on the power supply for the scan head.
(3) Turn on the laser.
When shutting down the system, turn off the compo-
nents exactly in reverse order.
Caution!
• Remove the protective covers from the scan
head’s beam entrance and beam exit or objec-
tive prior to first-time operation.
Caution!
• Before first-time operation, check the polari-
ties of the power supply connections for the
scan head.
• Always turn on the control (PC) and the power
supply for the scan head prior to turning on
the laser. Otherwise there is the risk that the
laser beam might be deflected in an arbitrary
direction.
• Power for the scan head must be applied only
when the control (PC, RTC
®
and control soft-
ware) are active.
