Switch 3 = b:
The signal "object present" is
transferred to the switching
output after a delay.
• In the case of S1 =
output switches ON after the
rising edge + t.
• In the case of S1 =
output switches OFF after the
rising edge + t.
A pulse during the time t triggers
the timer again.
Operation
Check the safe functioning of the photocell.
Display by LEDs and function-check output.
• Green LED is lit = supply voltage o.k.
• Red LEDs are lit = light reception (no object between photocell and
reflector).
• Red LEDs flashing = reception deteriorating (e.g. by soiling of the
lenses or maladjustment).
• Yellow LED is lit = output switched.
The function check output indi-
cates a wrong object detection
(soiling of the lenses, maladjust-
ment) by means of a 5 Hz signal.
When the object is again clearly
detected, the output provides
again a continuous signal.
Maintenance: Keep the lens of the sensor free from soiling.
