Came ZA4 control panel

[benbrooks]

Hi guys I have a problem with my gates, it started out as an intermitent problem but my gates are now permenently open. The red light on the panel is on does this indicate a photocell problem and the psensors detect an obstacle? Cheers in advance.

Hi Pat,

Thank you for your message.

I would firstly start by linking out safety inputs on the control board, if the gates are able to open but not able to close then this is usually down to a safety fault.
Please bridge across the following terminals:
1-2
2-C1

Another theory is it could be a access control device relay contacts that have shorted together by a cable short fault, whatever is wired into terminals 2 and 3, take them out and try the gates after trying the above.

Many thanks 

Ben
