<Reference: Preventing light interference of muting sensor>
When a photoelectric sensor is used as a muting sensor, light interference may cause a muting error of
F3SJ-B.
The cause and measures for light interference are shown as follows:
(1) Interference between muting sensors
Variable
Variable name
Value
Description
T1min
Muting input time limit value
(minimum)
0.1 s
Minimum time difference between muting inputs 1 and 2.
If the time difference between muting inputs 1 and 2 is smaller
than this value, a muting error occurs.
T1max
Muting input time limit value
(maximum)
3 s
Maximum time difference between muting inputs 1 and 2.
If the time difference between muting inputs 1 and 2 is larger than
this value, a muting error occurs.
T2
Muting time limit
60 s
This is the muting function continuation time.
If muting state exceeds this time, the function is canceled.
T3
Maximum muting input pulse
duration
0.1 s
Maximum muting input time with allowable waveform cracks in
muting input 1 and 2.
