Safety distance for safeguarding danger points
!WARNING
Never install an F3S-TGR-CL system without
regard to the safety distance. If the F3S-TGR-
CL system is mounted too close to the point of
operation hazard, the machine may not stop in
time to prevent an operator injury.
An F3S-TGR-CL system must be mounted far enough from the machine dan-
ger zone so the machine will stop before a hand or other body part reaches
the hazardous area. This distance is called the safety distance. It is a calcu-
lated number based on a formula.
The safety distance "S" is the minimum safe distance between the safety light
curtain and the point of operation (pinch point).
Calculation of the safety distance "S" is based on the European standard
EN999 and applies to safety light curtains that are used in industrial environ-
ments.
Direction of
approach
Additional countermeasures may be necessary to prevent access to the dan-
gerous area from above, below, the sides or the rear of the machine.
