Remarks
Approved purpose:
This product may only be
used by qualified person-
nel and must only be used
for the approved purpose.
This sensor is not a safety
sensor and is not to be
used for the protection of
persons.
Functional earth must be
wired.
Extraneous light sources
must not beam into the
receiver from the front.
Objects ≤ 1mm should be
scanned in front of the
receiver.
Only fiber-free cloths may
be used to clean optics
covers. Tips and hard
objects damage the
optics.
