1)
Under normal operating conditions, the yellow level indi-
cation LED has to be on steadily (bright) and alarm output
has to be high.
2)
The alarm output will turn on shortly each time an object
enters or exits the sensing zone, even if the photoelectric
switch is correctly installed and adjusted. To avoid false sig-
nals, the alarm functions should be delayed with an exter-
nal ON delay timer (i.e. Carlo Gavazzi timer S111 series).
