Omron Sti F3SJ-E N25 Series User Manual page 8

Perform an inspection for all F3SJ-E/B as described in "Chapter 5 Checklists".
Install muting sensors so that they can distinguish between the object that is being allowed to be
passed through the detection zone and a person. If the muting function is activated by the
detection of a person, it may result in serious injury.
Use independent two input devices for muting inputs.
The muting and override functions disable the safety functions of the device. You must ensure
safety using other method when these functions are operating.
Install the switch that uses hold-to-run device such as a spring-return key switch and is installed
in a location that provides a clear view of the entire hazardous zone and where it cannot be
activated from within the hazardous zone. Make sure that nobody is in the hazardous zone
before activating the override function.
For wiring
Connect the load between the output and +24 V line (NPN output). Connecting the load between
the output and 0 V line will result in a dangerous condition because operation is reversed to "ON
when blocked".
Do not short-circuit the output line to the 0 V line. Otherwise, the output is always ON. Also, the
+24 V of the power supply must be grounded so that output does not turn ON due to grounding
of the output line.
Configure the system by using the optimal number of safety outputs that satisfy the requirements
of the necessary safety category.
Do not connect each line of F3SJ-E/B to a DC power supply of more than 24 VDC+20%. Also, do
not connect to an AC power supply. Failure to do so may result in electric shock or breakdown of
the device.
Make sure to perform wiring while the power supply is OFF.
Do not use the auxiliary output for safety applications. Human body may not be detected when
F3SJ-B fails, resulting in serious injury.
