4.3.1 Air blow-off for laser sensors
To prevent contamination of the sensors it is necessary to provide a continuous air blow-off.
This is done by connecting an air hose with 8 mm outer diameter.
A permanent air blow-off of approx. 0.5 bar pressure is recommended, alternatively 5 bar
cyclic cleaning.
Possible contamination
Oil, oil mist, water
Rough tinder
Dust, fine tinder
Note
To disconnect the hose use an 8 mm or 9 mm open-ended wrench as shown in Fig. 6, right.
For the supplied purging air there are requirements regarding purity and freedom from oil.

The requirements are:

Operating medium: compressed air according to ISO 8573-1: 2010 [-: 9: -] inert gases (see

table)
Air purity class at the output: compressed air in accordance with ISO 8573-1: 2010 [1: 7: 2] inert

gases (see table)
Oil freedom: remaining oil content 0.01 mg / m

Air loss causes contamination!
A process-safe operation will be therefore no longer guaranteed!
