Description
Cap error
Communication error
Safety output error
Input wiring error
External device monitoring error
Internal error
Configuration error of emitter-
receiver combination
Ambient light error
A cap may be detached. Attach the cap properly.
The communication line or other wiring may be broken or short-circuited.
Check the wiring and cables.
A power cable may be detached.
Check connectors of the power cable.
If the wiring is extended with cables other than specified, the cables used for extension may not
have performance equivalent or greater than the specified cables. Use cables with the same
performance or more than the specified cables.
See "Wiring" in Chapter 3.
Safety output lines may be short-circuited to each other or another signal line may be short-
circuited to the safety output line.
Wire the safety output lines properly.
See "Wiring Diagrams" in Chapter 2 or "Wiring" in Chapter 3.
Combinations of interlock select input line and reset input line may be wrong.
The reset input line may not have been properly wired when a muting key cap was mounted.
Perform correct wiring.
See "Wiring Diagrams" in Chapter 2 or "Wiring" in Chapter 3.
Emitter(s) and receiver(s) may be reversely connected to connectors on a controller. Check the
connecting positions with the connectors.
If the external device monitoring input line is short-circuited to the auxiliary output line instead of a
relay, the auxiliary output line may be broken or short-circuited to another line.
Relay may be welded.
Replace the relay.
The relay and external device monitoring input line may not be properly wired.
Check the wiring with the relay.
See "Wiring Diagrams" in Chapter 2 or "Wiring" in Chapter 3.
The relay response time may be exceeding the allowable delay time (0.3 s).
Replace the relay with one that has an appropriate response time.
See "Wiring Diagrams" in Chapter 2 or "Wiring" in Chapter 3.
An error may have occurred in the internal circuit.
Replace the F3SJ-E/B.
A model name does not match between emitter and receiver. Check that the emitter and receiver
are the same model.
Series connection cables may have been short-circuited, broken or disconnected. Check if series
connection cables are connected properly. Replace a series connection cable if it is broken.
The receiver may be receiving light emitted from another photoelectric switch or F3SJ-E/B.
