F3S-B

WIRING and MOUNTING

2-1 Installation Conditions

Do not use the F3S-B on machines that can not be stopped by electrical control in case of an emer-
gency.
Do not use the F3S-B in flammable or explosive environments.

2-1-1 Detection Zone and Intrusion Path

Install protective structures around a machine so that you must pass through the detection zone to reach
a hazardous part of the machine.
Install the F3S-B so that some part of the operator's body remains in the detection zone at all times
when the operator works in a hazardous area.
Failure to do so may result in serious injury.
Correct installation
A hazardous part of a
machine can be reached only
by passing through the
sensor detection zone.
Incorrect installation
A hazardous part of a
machine can be reached
without passing through the
sensor detection zone.

2-1-2 Safety Distance

Always maintain the safety distance between the F3S-B and a hazardous part of a machine. Serious
injury may result if the machine does not stop before someone reaches the hazardous part.
The "Safety distance" is the minimum distance that must be maintained between the F3S-B and a hazard-
ous part of a machine in order to stop the machine before someone or something reaches it.
The calculation of safety distance varies according to with national standards and individual machine
standards. It also depends on the direction of intrusion to the detection zone of the light curtain, perpen-
dicular, parallel, or angled approach, and depends on the application, e.g. non-industrial applications
where children are present.
See related standards for more details.
