User’s Manual
Introduction
E
•
When extending the communication line with a cable (twisted-pair wire) other than the dedicated cable
(F39-JD
), use a cable with the same or superior specifications. Connect the shield to the 0V line.
Cable specification (extension cable) p.69
•Properly perform the wiring after confirming the signal names of all the terminals.
•Be sure that there is nothing in the detection zone and the stable-state indicator is turned ON after
power is turned ON.
•Do not operate the control system until 2 seconds or more after turning ON the power of the F3SJ-B.
•Be sure to route the F3SJ-B cable separate from high-potential power lines or through an exclusive
conduit.
•When using a commercially available switching regulator power supply, make sure to ground the FG
terminal (frame ground terminal).
•If the protective height is more than 1,105 mm, use intermediate brackets of specified quantities and
locations according to the dimensions.
If the brackets described above are not used, ratings and performance cannot be met.
•Do not install the F3SJ-B close to a device that generates high-frequency noise. Otherwise, take
sufficient blocking measures.
•Sharing the power supply with other devices may cause the
F3SJ-E/B
to be affected by noise or
voltage drop. It is recommended that this safety component use a dedicated power supply but do not
share with other devices.
Cleaning
Do not use thinner, benzene, or acetone for cleaning, because they affect the product's resin parts and
paint on the extrusion.
Object detection
The F3SJ-B cannot detect transparent and/or translucent objects.
