Multiple safety laser scanners with airWiper

If the airWipers of several safety laser scanners are supplied from a common com‐
pressed air source, then it must be ensured that the compressed air is sufficient for all
airWipers. The pressure must be sufficient even if several airWipers are activated at the
same time.

If the pressure is not sufficient to supply all airWipers at the same time, then you need
to use the controller to ensure that the airWipers are activated one after the other.
