F3S-B
5
Notice
For your safety, always pay attention to the following:
#
Installation Environment
•
Do not install the F3S-B in the following environments:
−
Areas exposed to intense interference light such as direct sunlight.
−
Areas with high-humidity where condensation is likely to occur.
−
Areas exposed to corrosive gases.
−
Areas exposed to vibration or shock levels higher than specification provisions.
−
Areas where the light curtain may come in direct contact with water.
•
Do not use radio equipment, such as cellular phones, walkie-talkies, or transceivers with high power,
near the F3S-B.
#
Wiring and Mounting
•
Be sure to route the F3S-B cable separate from high-potential power lines or through an exclusive
conduit.
•
Be sure to turn OFF the power prior to wiring. Otherwise, the diagnostic function may prevent the
sensor from operating.
•
When using cables with a connector other than the F39-JB series cable, make sure the connector is
rated IP54 or higher.
•
The F3S-B will start operating in two seconds after the power is turned ON. Make sure that no op-
eration faults will occur in the control system during this time.
•
The emitter and receiver are to be mounted in parallel and facing one another.
#
Loads must satisfy all the conditions below.
•
Is not short-circuited.
•
Is not used with current higher than the rating.
•
Is reinforced insulated or double insulated as shown in the following figure to prevent the output
from being subjected to a hazardous voltage when the load is a relay. The insulation shown in the
figure below should insulate against hazardous voltage levels (230 VAC, etc.), not simply against 24
VDC.

Two control outputs must be used.
#
The procedures of installation and inspection in this manual should be read carefully.
#
Do not use any solvents such as paint thinners, benzene or acetone to clean the F3S-B because they
will dissolve resin and paint.
#
Do not use screw-locking adhesives (screw lock) to secure the cap unit or connector cap screws be-
cause the adhesive may cause the resin to deteriorate and crack.
#
The F3S-B can not detect transparent or semi-transparent materials.
#
After unpacking the emitter and receiver, install them facing each other.
#
Be sure to dispose of the F3S-B as industrial waste.
