Bft Ares Gate not closing

[Hatbat]

Hi Hatbat,

There are a few thing i would check, first of all i would check that there is nothing covering the lens inside the photocell covers like insects or dust which could be blocking the beam. If these are clean and you are still having problems with the gates stopping in the open position i would do a continuity test of the cables from the board to the photocells to make sure there are no breaks. Hope this helps.

Hi Tim,

Thanks for your reply. I have checked the photocell covers - all looks fine.

Is a power supply of 3.3V going to the Tx and Rx sufficient? The photocells work fine in the office connected to a power supply (relay toggles and output changes as expected) but not in situ - even if I put the Tx within 4" of the Rx to see if I can hear the relays work.
