Notice
For your safety, always heed the followings:
(1) The procedures of installation, inspection and maintenance in this manual should be read carefully.
(2) Loads must satisfy all the conditions below:
•
Is not short-circuited.
•
Is not used with current higher than the rating.
(3) All input lines and output lines of the F3SN-B should insulate against hazardous voltage levels (230 VAC,
etc.), not simply against 24 VDC, with double or reinforced insulation to protect against electrical shock.
In case of the combination with the F3SP-B1P, all relay output terminals (13-14, 23-24, 33-34, and
41-42) should insulate against hazardous voltage levels with basic insulation.
(4) Be sure to dispose of the F3SN-B as industrial waste.
Correct Usage
For your safety, always heed the following:
Installation Environment
•
Do not install the F3SN-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 F3SN-B.
Wiring and Mounting
•
Be sure to turn OFF the power prior to wiring, otherwise the diagnostic function may prevent the
light curtain from operating.
•
Use shielded twisted pair cable (cross-sectional area:
φ
0.3mm
2
or more) when extending the
communication lines with a cable other than the dedicated cable (F39-JC ), and connect the shield
to the 0V line.
•
When replacing the cable connector with other connectors (e.g. resin connectors), make sure the
connector is rated IP54 or higher.
•
When the distance between the emitter and the receiver is less than 0.2m, there is a possibility of
the malfunction that the F3SN-B goes to the OFF-state momentary. Be sure to install the F3SN-B
within the rated operating range.
•
Check the signal name of all terminals for correct wiring.
•
Devise a measure to protect against mutual interference when using two or more sets of F3SN-B
beside one another.
•
Do not operate the control system until one second or more after turning ON the power of the
F3SN-B.
•
Be sure to route the F3SN-B cable separate from high-potential power lines or through an exclusive
conduit.
•
The emitter and receiver are to be mounted in parallel and facing one another.
Do not use any solvents such as paint thinners, benzine or acetone to clean the F3SN-B because it will
dissolve resin and paint.
The F3SN-B cannot detect transparent or semi-transparent materials.
