Appendix
Temporary power supply voltage
reduction in motion.
Check for temporary power
supply voltage reduction (by about
12VDC) by the influence of the
induction load etc. If the exclusive
power supply is not used, check
the power consumption of other
connected devices for enough
capacity.
Connection positions are reversed
for emitter(s) and receiver(s)
under series connection.
Correct connection positions of all
F3SJ's emitters and receivers.
Failure of F3SJ's internal circuit. Replace the F3SJ.
The setting tool is connected to
series connection that includes
F3SJ of version 1.
The setting tool cannot be used if
the connection includes F3SJ of
version 1. Do not connect F3SJ of
version 1.
38 Lockout of other
sensor than the
primary receiver
(error mode
indicator will not
turn on)
A sensor other than the primary
receiver is in lockout when series-
connected.
Solve the problem of an emitter or
F3SJ in a series connection.
3A Excessive number
of beams
Total number of beams of F3SJs
under series connection exceeds
400.
Rearrange series connection so
that total number of beams of
series connection should not
exceed 400.
3B Excessive number
of connected
sensors
Five or more sensors are
connected.
Number of F3SJs under series
connection must be 4 or less.
3C Model error
(between series
connection)
Models of the primary sensor and
secondary sensor are unavailable
for connection. (Primary: PNP
Output, Secondary: NPN Output,
etc.)
Connect them properly.
p.120
3D Model error
(between emitter/
receiver)
Models are different between an
emitter and a receiver (lengths,
output types, or beam gaps are
different)
3E Sensor count
error (no emitter)
Number of emitters under series
connection is less than that of
receivers (emitters: 3, receivers:
4, etc.)
3F Sensor count
error (no receiver)
Number of receivers under series
connection is less than that of
receivers (emitters: 4, receivers:
3, etc.)
40 Setting value error Function setting value configured
by the setting tool is out of valid
range.
Perform setting recovery to
restore factory settings.
p.108
Muting enabling keycap is
attached but muting/override
information is not assigned to
either of auxiliary output 1,
external indicator output 1 or 2.
To use muting function, muting/
override information must be
assigned to at least one of
auxiliary output 1, external
indicator output 1 or 2.
