Panasonic SF4D-TM1 User Manual page 9

♦ Fixed blanking and floating blanking functions
● When the sensing area is invalidated by the fixed blanking function, set up a protective
structure that will prevent humans and physical objects from passing through the invali-
dated sensing area and reaching dangerous parts of the machine.
Risk of death or serious injury if a human body is not detected.
● The floating blanking function is used to change the size of the smallest detectable object
of the SF4D series light curtain ("light curtain" below) on which the function is set. When
setting or changing the function, recalculate and remeasure the safety distance, and verify
that the distance between the dangerous part of the machine and the sensing area of the
light curtain on which the function is set is always greater than the safety distance.
If a sufficient distance is not established, the machine will not be able to stop before a hu-
man body or object arrives at a dangerous part, creating a risk of death or serious injury.
● Always ensure that applicable laws and regulations are observed when setting or chang-
ing the function.
♦ Muting setting change function
● The muting setting change function temporarily invalidates the safety functions of the light
curtain. Check all applicable laws and regulations, and install and operate correctly. Risk
of serious injury to the operator if these requirements are not satisfied.
