User’s Manual
Appendix
3A Excessive number
of beams
Total number of beams of F3SJs
under series connection exceeds
240.
Rearrange series connection so
that total number of beams of
series connection should not
exceed 240.
3B Excessive number
of connected
sensors
Four or more sensors are
connected.
Number of F3SJs under series
connection must be 3 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.52
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: 2, receivers:
3, etc.)
3F Sensor count
error (no receiver)
Number of receivers under series
connection is less than that of
receivers (emitters: 3, receivers:
2, etc.)
4E Cap position error Failure of F3SJ's internal circuit. Replace the F3SJ.
4F Cap error Cap is not attached. Attach the cap properly.
50, 51, 52, 53 External device
monitoring error
Relay is welded. Replace the relay.
The relay and external device
monitoring input line are not
properly wired.
Check the wiring for the relay.
The relay response time exceeds
the allowable delay time.
Replace the relay with one that
has an appropriate response time.
If short-circuit is made to an
auxiliary output instead of a relay,
the auxiliary output line is broken
or short-circuited.
Make sure there is no failure in
the external device monitoring
input and auxiliary output lines.
Emitter(s) and receiver(s) are
reversely connected when
connected to connector type
controller.
(Connectors of F3SP-B1P's
emitter/receiver are reversely
attached, etc.)
Check connectors' positions.
