Self-diagnosis function(Common)
When fiber hood is contaminated by dust, transmitted
light is lowered by element ability loss or received light is
lowered by missing of optical axis, the self-diagnosis output
will turn on.

①
output(Alarm)
①The self-diagnosis output turns off during stable
detection.(① position)
② When detecting state remains for 300ms at unstable
level between stable light OFF level and stable light
ON level, self diagnosis output turns on, self-diagnosis
output turns off at lower than stable light OFF level and
upper than stable light ON level. (② position)
③ When the control output turns on, if an overcurrent
condition exists in control output, then self-diagnosis
output turns on.

Interference prevention function
(Common)
BF4R series has interference prevention function, two
fiber optic cables can be mounted very closely by setting
different transmission frequencies.
●Interference prevention function
(Operation of differential frequency mode)
First sensor- Frequency 1(Response time: max. 0.5ms)
Move to
① Set the mode selection switch to [SET].
② Press the [ON] & [OFF] buttons for
2sec. at the same time.
③ The [STAB] indicator flashes continuously.
④ Press the [ON] button.
⑤ The [STAB] indicator turns off.
⑥ Set the mode selection switch to [LOCK].
Second sensor- Frequency 2(Response time: max. 0.7ms)
① Set the mode selection switch to [SET].
② Press the [ON] & [OFF] buttons for
2sec. at the same time.
③ The [STAB] indicator flashes continuously.
④ Press the [OFF] button.
⑤ The [STAB] indicator turns off.
⑥ Set the mode selection switch to [LOCK].
● Interference prevention function
(Operation of normal mode)
① Set the mode selection switch to [SET].
② Press the [ON] & [OFF] buttons for 2 sec. at the same
time.
③The stable indicator flashes continuously.
④ Press the [ON] & [OFF] buttons at the same time.
⑤The [STAB] indicator turns off.
⑥Set the mode selection switch to [LOCK].
※ When interference prevention function is used,
hysteresis & response time will be longer than normal
operation(Response time : Max. 0.5ms).
