How to reset lockout: See p.33 for basic system and p.55 for muting system
For information about lockout, see p.196
Waveform of Safety Outputs
When the F3SJ is receiving light, the safety outputs cyclically turn OFF as shown below to test the
output circuit. When this OFF signal is fed back, the output circuit is diagnosed as normal. If the output
signal does not include an OFF pulse signal, the receiver diagnoses a failure in the output circuit or
wiring, and it enters lockout state. (See the table below.)
Auxiliary Output (Non-Safety Output)
The auxiliary output is used to monitor the status of the F3SJ. This output can be connected to a
device such as a relay, indication lamp, programmable controller, etc.
Do not use the auxiliary output or external indicator output for safety applications.
Human body may not be detected when F3SJ fails, resulting in serious injury.
There are 2 auxiliary outputs: auxiliary outputs 1 and 2.Initial setting is assigned as shown below.
•Auxiliary output 1: Inverse of safety output signals
•Auxiliary output 2: Turns ON when 30,000 hours of power-on time passes
Auxiliary output 1 and 2 are load current 300mA and 50mA max respectively.
