Access Guarding; Danger Zone Guarding - Wieland SLC Series Operating Instructions Manual

5.2 Access guarding

Safety sensors with up to 90 mm resolution are used for access guarding into danger zones.
They detect people only upon entry into the danger zone, i.e., they do not detect parts of a per-
son or whether a person is present in the danger zone.

5.3 Danger zone guarding

Safety light curtains can be used in horizontal arrangement for danger zone guarding - either
as stand-alone device for presence monitoring or as stepping behind protection for presence
monitoring e.g. in combination with a vertically-arranged safety sensor. Depending on the
mounting height, resolutions of 40 or 90 mm are used (see chapter 15 "Order guide and acces-
sories").
