What can be done by the setting tool
Maximum time difference between muting inputs 1 and 2.
Minimum value must be less than maximum value.
•T2: Muting time limit
Time to be continued for muting function. If muting state exceeds this time, the function is canceled.
•T3: Maximum muting input time with allowable waveform cracks
Indicates maximum time limit to allow waveform cracks regarding the muting input 1 and muting
input 2 in the effective muting state. It is set as 0.1s.
•T4: Muting end waiting time
OFF delay time from F3SJ's light incidence to release of muting state. It is set as 0.1s.
•T5: Exit only muting delay time
OFF delay time from muting input 1 or 2's signal turning OFF to release of muting state.
If either of the following conditions are present, muting ended. In this timing chart, T4(0.1s) condition releases the
muting state.
1. When exit only muting delay time T5 exceeds the setting value.
2. When a workpiece passed F3SJ's detection zone and muting waiting time T4(0.1s) passed.
3. When muting continuance time exceeds muting time limit T2.
3. Position Detection Muting Mode (Setting is Available only for PC Tool For F3SJ)
Muting function is enabled when muting input 1 turns ON from OFF and muting input 2 turns OFF from
ON within the input time difference T1max, measured by a limit switch, etc. Muting inputs must be
heterogeneous redundant inputs such as N.O. contact and N.C. contact types. (In case of NPN output
type photoelectric sensor, use one by L/ON operation while the other by D/ON)
This can be used for such a case that F3SJ should be temporarily disabled as the switch is so
operated by a worker who puts an object at a carry-in entrance.
• Start Conditions
If both of the following 2 conditions are present, muting is activated.
1. No interrupting object is found in the F3SJ's detection zone, and safety output is ON.
2. After muting input 1 is turned ON (connected to 0 to 1.5V) from OFF, muting input 2 is turned ON
(connected to 0 to 1.5V) from OFF within the muting input time limit T1max (3 sec.: can be changed to
between 0.1 and 4 sec.). Order of muting inputs 1 and 2 is irrelevant.
When condition 1 is satisfied but time of condition 2 is not, a muting sequence error occurs and
receivers muting error indicator turns ON.
A muting error is canceled when either of the following condition is satisfied.
Muting is started by a proper muting sequence.
Cycle the power back ON with muting input 1 OFF and muting input 2 ON.
• End Conditions
If either of the following condition is satisfied, muting state will be released.
1. Muting input 1 stays OFF for maximum muting input time with allowable waveform cracks T3
(0.1sec. ) or longer.
2. Muting input 2 stays ON for maximum muting input time with allowable waveform cracks T3
(0.1sec.) or longer.
3. When muting continuance time exceeds muting time (60s: can be changed).
Muting state can be also released when the sensor enters lockout.
