Faac gate opens when photo cell beam is broken

[RyanB]

Hi Stephen,

Photocells are generally used to stop and reopen gates when the are obstructed while the gates are closing. This is generally to avoid damaging vehicles which could be attempting to drive through as the gates start to close. It is not usually recommended to wire the photocells into the emergency stop command but I can explain how this is done below.

Going from the colours of the wires from the image you provided, you should have a green and white wire going terminal 12 and terminal 19, these will need to be removed and a wire bridge will need to be put between terminals 12 and 19. You will then need to remove the wire bridge from terminal 11 and terminal 14 and replace this with the green wire going to terminal 11 and the white going to terminal 14. If you already have wires going into terminals 11 and 14 you will need wire the 4 wires in series to allow the photocells and other STOP device to function.
