5.1 Connecting the compressed air hose
Important information
WARNING
Concealment by compressed air lines
Compressed air lines or other small objects in the near range (< 50 mm in front of
the optics cover) may not be detected and may obscure persons or body parts in the
protective field.
b
Route compressed air lines so that they do not protrude into the required viewing
slit.
b
Ensure that no small objects (e.g., cables) are in the protective field, even if this
means that the safety outputs do not switch to the OFF state.
b
Ensure that there are no objects between the base and the curved part of the
optics cover (e.g., cables) that could interfere with the contamination measure‐
ment.
Prerequisites
Compressed air hose
• Outer diameter: 4 mm
• Cut square
• Deburred
Approach
1. Insert the compressed air hose as far as it will go. Make sure that the compressed
air hose is inserted into the seal.
2. To check for a secure hold, pull lightly on the compressed air hose.

5.2 Detaching the compressed air hose
Prerequisites
• The compressed air supply is switched off and vented.
Approach
1. Slide the ring on the compressed air connection in the direction of the airWiper
and hold it in place.
2. Carefully pull out the compressed air hose.
3. To use the compressed air hose again, cut off the damaged part.
5.3 Replacing the compressed air connection
Overview
The compressed air connections are replaceable. The airWiper is equipped as standard
with connections for 4 mm compressed air hoses. You can use other compressed air
connections with an M5 thread instead. The nominal diameter of the compressed air
connections should not be less than the nominal diameter of the individual channels.
Otherwise the air flow will be limited and the cleaning effect reduced.
