3.6 Functional test
Under unfavourable conditions like rain or fog as well as a poor alignment of the photoelectric barrier,
the range of the photoelectric barrier may be sharply reduced.
The supplied filter (foil) is used to simulate these unfavourable conditions.
Drawing 8
For the simulation apply the foil either to the transmitter or to the receiver. To check the correct
functioning of the photoelectric barrier, interrupt the infrared beam several times (the red LED at the
receiver has to light up and the relay must switch). Should the photoelectric barrier not function
correctly, either the range limit is reached or the alignment of the photoelectric barrier or the alignment
of the light beam has to be corrected.
Remove the foil after the functional test is completed!
