I have tried to locate a manual (as seen in the picture) on FAAC's website. The model number XF 433 turns out to be the code of the radio module.

enter image description here

At the moment the a swing leaf gate it controls is not responding. I suspect it is caused by a blown fuse due to a recent storm.

Where is the fuse and how can I replace it? Do I need to remove the radio module (XF 433) before I take of the frosty plastic cover?

    why don't you take off the cover and look for a fuse? – jsotola Jan 09 '21 at 02:58
  • Do you mean the frosted plastic cover? I am not familiar with the unit, so I want some instructions. – Anthony Kong Jan 09 '21 at 03:00

    it's not rocket science ... wiggle the cover ... look for latches or screws at places where the cover appears to bind ... otherwise, call a gate service tech – jsotola Jan 09 '21 at 03:07
  • Are you just making a general commentary or you indeed know about this hardware? – Anthony Kong Jan 09 '21 at 03:09
  • general commentary and lots of experience with many various pieces of hardware – jsotola Jan 09 '21 at 03:17

    Most of us won't have specific experience with a given piece of hardware -- but it turns out engineers who make hardware tend to follow patterns. We learn to identify those patterns. There are a red+black pair of wires going to the top, near where the frosted cover says POWER. Through the cover we see an array of cylinders with silver tops; both of these things are signs that the board's power supply is in that area. If the board has a fuse on its input that's the area where it'll almost certainly be found. Figure out how to remove the cover and have a look. – Greg Hill Jan 09 '21 at 03:35
  • Are you sure the controller unit is an "FAAC XF-43"? Could that just be the make and model of that individual component? – Jimmy Fix-it Jan 09 '21 at 03:35
  • @JimmyFix-it It turns out 433 is the model number of the radio unit. The control board seems to be a E024S but I am not 100% sure. – Anthony Kong Jan 09 '21 at 03:38
  • @GregHill I agree with your general principle, but I come to this site looking for more specific advices. – Anthony Kong Jan 09 '21 at 03:40
  • @Anthony Kong- is it powered by house voltage (AC) or by a charger and battery (DC)? – ojait Jan 09 '21 at 03:41

    @ojait House voltage. – Anthony Kong Jan 09 '21 at 03:41
  • Can you check the power source (outlet) to verify there's power? – ojait Jan 09 '21 at 03:44
  • If not the breaker may need to be reset that the controller is powered by. – ojait Jan 09 '21 at 03:46
  • Yeah, the power socket is live. – Anthony Kong Jan 09 '21 at 03:47
  • So the problem does lie in the board. The fuse would look like a small glass cylinder held in place by 2 "u" shaped clips. Theres a thin wire in the center that will probably be burnt. Take a wider photo and I can try to help more. – ojait Jan 09 '21 at 03:51

The fuse is located under the logic board. (see attached photo)

It is actually not necessary to remove the frosty plastic cover of the logic board. As a matter of fact, removing the cover incorrectly could bend and damage the pins of the radio module.

The fuse is a glass fuse T2A.

@Anthony Kong- There is a fuse. It may be resettable or replaceable. Here's your link for the maanual. Let me know what happens or if I can help.

    I'm not a downvoter, but link-only answers (which this is basically) are discouraged since links can die. I'd suggest going though the manual and transcribing the fuse information into your answer, – DoxyLover Jan 09 '21 at 07:35
  • yeah it takes half a minute to copy a screenshot from a pdf or web page into an answer, less if you can cut and paste text. – Jasen Jan 09 '21 at 11:14
  • @ojait Actually, I am correct. Here is a direct quote from the help page on writing answers: “ Always quote the most relevant part of an important link, in case the external resource is unreachable or goes permanently offline.” – DoxyLover Jan 09 '21 at 23:18
  • I said "link only answers are discouraged" not "link answers are discouraged". – DoxyLover Jan 10 '21 at 02:05
  • this is an answer with a link. i answered "there is a fuse..." and shared a link. – ojait Mar 11 '21 at 22:40
  • and the comment from the OP stating this answer was helpful gets deleted? – ojait Mar 11 '21 at 22:41
