The photocell TEST ensures that the automation only fun-
ctions when the photocells are functioning properly.
In fact, the control unit performs the test before each ope-
ning. If there is a photocell malfunction, the control unit
turns the fl ashing lights on for 5 seconds and the automa-
tion does not start.
