Maintenance

6.1

Regular cleaning

Overview

The safety laser scanner and the optics cover must be cleaned regularly as per the
operating instructions of the safety laser scanner.

The airWiper must be cleaned regularly to prevent the air nozzles from clogging or
corroding. In environments where heavy contamination or salt water (e.g., due to road
salt) occur, the airWiper must be cleaned more frequently.

Important information

DANGER

Improper work on the product
A modified product may not offer the expected protection if it is integrated incorrectly.

b

Apart from the procedures described in this document, do not repair, open, manip‐
ulate or otherwise modify the product.

Approach

1.

Moisten a clean, soft cloth and use it to wipe all air nozzles of the airWiper (on the
inside and underneath).

2.

Activate the airWiper to clean the air nozzles.

3.

Check the air nozzles for visible residues.

4.

Check the cleaning function.

6.2

Maintenance of the compressed air supply

Overview

Depending on the selected compressed air supply, the system should be serviced
regularly. The following instructions are intended as a guide only. Depending on your
application, additional or different measures may be required.

Approach

b

Drain any condensed water at the condensate drain.

b

Clean and check the particle filter.

b

Check, clean and, if necessary, replace the oil filter.

b

Flush the compressed air lines before commissioning and after a long downtime.

6.3

Regular thorough check

Overview

The safety laser scanner must be checked regularly in accordance with the inspection
plan of the safety laser scanner (for more information, see the operating instructions of
the safety laser scanner, “Inspection plan” section).

The airWiper must be checked regularly.
