1.4 Ambient conditions
The ambient temperature for the operation of the machine must be
b10 °C and +43 °C. The temperature at the installation
site must not be allowed to fall below +4 °C when the system is
switched off.
Note
One-sided exposure to direct sunlight and unidirectional drafts
(heat distortion) must be avoided (e.g. with Venetian blinds if the
control unit is set up at a window).
To prevent deterioration of beam quality, ensure that the
installation site of the laser is free of particles or substances which
absorb radiation with a wave length of 10.6 µm. These are e.g.
solvent gases, which are released when enameling, that come
from the degreasing units.
If the ambient temperature is b35 °C - +43 °C the system
must be equipped with the tropical version of the laser.
The control system is cooled by inner air circulation in the closed
control cabinet. This ensures that components are extensively
protected against dirt and dust.
The heat dissipation from the control system housings is normally
performed by external heat exchangers with fans which suck in air
directly and blow it along the cooling elements. Make sure that
there is no excessive air contamination in the intake region of the
fan behind the control system, as dust on the cooling elements
greatly reduces heat transfer.
Damp rooms are not suitable for the operation of the control
systems, principally because contact corrosion may develop on
contactor and relay contacts, leading to control errors.
