Photocells do not stop the gate, Faac 740D + Connection diagram

Best answers LABEL_AI_GENERATED

Why do my photocells click and turn off their LED when interrupted but still fail to stop a Faac 740D gate drive?

The photocells were not stopping the gate because a bridge/jumper was left in the wiring; removing it fixed the problem [#16616843] If the FSW CL indicator on the control board goes out when the beam is interrupted, the photocells are connected correctly and should be able to trigger the stop input [#16614741] The marked “bridge” in the diagram is actually the symbol of the internal NC relay contacts inside the photocell, not an external jumper to install [#16616813] Once the bridge was removed, the system worked [#16616843]

    Bama works as it should except for photocells.
    What can be the reason that photocells "click" when they are interrupted and the diode goes off but they do not interrupt the drive?

    They do not work at all closing or opening?

    And the colleague read the instructions?
    You have the wrong mounting direction for the drive.
    In the basic menu, the dI parameter.

    Yes, they do not work on closing or opening.

    I connected the gate according to this scheme and it works. The pilot also works.
    In 50s the author gave a scheme for connecting photocells - it does not work.
    I tried to connect these photocells in two ways: according to the scheme from the manual and according to the scheme from YouTube. Does not work.

    Thank you for such a quick response, I won't be able to check it until Monday. Now I have to go to a wedding.

    If it adds FSW CL on the control panel goes out when the beam is cut, the photocells are connected correctly.

    I replaced this drive parameter, it doesn't work either. The photocells continue to "click" but do not stop opening or closing the gate.
    Maybe I connected something wrong?
    I marked the current connection of photocells in red. Photocells do not stop the gate, Faac 740D + Connection diagram

    In the diagram there are numbers 1 2 3 4 5, in the photocell itself there are numbers 2,3,4,5. Photocell clicks but I will try to remove this bridge and see if it works.

    The diagram you marked and took as a jumper is a symbol of the internal contacts of the NC photocell relay ...

    I took off my bridge and it works :)
