Troubleshooting
Lockout State
If F3SJ detects any failure, it keeps safety output OFF and transitions to lockout state. Under lockout
state, an emitter and a receiver set interlock indicator and OFF indicator blinking respectively, and
F3SJ that detected the failure sets an error mode indicator ON or blinking based on the failure. Solve
the problems based on the table below.*1
Eliminate the cause of the problem. Then turn the power on again or provide the reset input to restart
the F3SJ.
*1 If communication error is indicated on primary sensor's receiver, it may be caused by other F3SJ
(emitter or secondary sensor). If a connector was disconnected before, especially in series
connection, ensure that connection should not be loose and that internal connector pins should not
be bent.
