Possible integration and operating positions for the TD412
The TD412 marking head may be assembled in various positions. We recommend the horizontal position, with
the laser beam directed downwards.
Where it is used with the laser beam pointing upwards, particles can be deposited on the focal lens, affecting
marking quality or even damaging the laser. A protective device can be inserted between the focal lens and the
part being marked. This protective device consists of a piece of glass with high transmittance treatment to 1064
nm. It should be placed as close as possible to the focal lens. The presence of the glass may reduce the marking
field.
1 : Protective guard between the marking head and the part
2 : Laser protection glass (HT@1064 nm)
3 : Marking laser - Marking in the upwards direction
4 : Plate to be marked
Control Unit
Position the Control Unit horizontally, in a dry, ventilated area, at least 20 cm (7.874 in) from the floor.
Always leave a free space of 50 mm (1.969 in) in front of the CCU and of 150 mm (5.906 in) in back for good air
circulation. As components are air-cooled, air circulation in the CCU must not be perturbed.
Version rack 19" 5U: used to integrate the CCU in a cabinet. Vertical position possible
Recommendations: work area lighting must be greater than 500 lux.
Do not use a piece of ordinary glass.
Clean the protective glass regularly to prevent loss of power and deterioration of the
marking quality.
The optical fiber connecting the CCU to the Laser module must never be bent to a
radius of below 90 mm (3.543 in).
Analyse the CCU’s integration in order to avoid problems due to the fiber’s minimum
bend radius.
