Stagnoli Hercules 500 - no 24V voltage for additional devices

Hello everyone,

I have a little problem. The case concerns the Stagnoli Hercules 500 drive for the sliding gate. There is no 24V voltage for additional devices. It's exactly about photocells. After connecting the photocells everything worked as it should, but when shortening the cables, which turned out to be too long, there was a short circuit. From this moment, unfortunately, there is no tension. Could someone guide me to solve the problem? Are there any fuses in the controller board? Could there be anything more to burn / damage? The driver is H230. I attach a photo of the driver, I hope that it will help in the diagnosis. Thank you in advance for all your help.

and if there is a short circuit when connecting the antenna cable? - it looks like this in the picture.

No, there is not, and even if there was a short circuit it should not have an impact on the described problem (?). It is possible that a semiconductor fuse would be responsible for the voltage?

This black casing on the plate next to the transparent relay with the word fuse ... There's a fuse inside, I just do not know if it's from the power supply of accessories or "from everything". Check it out yourself.

Unscrew the plate and check EXACTLY the paths that lead the voltage to the connector - how thin they are - could have somehow crashed. Also remove the plastic holder of the accessory connector (slide off the pins) - and check the print under it. Print guides also have a look - such burning can be tricky and well camouflaged.

This 24 or 12V is taken directly from the entire power supply (possibly through a limiting resistor) and the failure is somewhere on the way to the connector because in the event of a power supply failure, the whole control panel would not go. There is no fuse there on the way.

Thanks for the tips, I will look into the driver tomorrow. Let me know if I managed to get something. Greetings.

Thank you for help, there was a tubular fuse under the fuse lid, of course blown. After the exchange, everything as needs to be
