CAME ZF4 Controller Issue

[mduffy89]

Hi all,

Looking for some help with ZF4 controller.

Gates stopped opening at the weekend. Tried changing batteries in several remotes, but no joy.
There is power going to the control panel, but red light is flashing repeatedly.

I have seen other advice on this forum to link B and C1, but I cant see C1 on this panel.

Any help would be much appreciated.

Hi,
the condition of the PCB isn't in the best condition therefore it would point to external influences that could be creating a fault.
Are you able to send a photo of the PCB front and back to further identify the issue.
