Convert Existing Automatic Sliding Door to Operate with RPI

Question

Hi All

I would like to start a step by step project but need some advice first.

I have 2 x PC boards on separate automatic sliding doors that blew due to a power surge. Each of the boards plug into a 220volt dedicated wall plug. To replace these boards are very expensive. I want to operate the doors using Raspberry PI instead as its much cheaper and you can do so much more.

Would i need a Unipi or can i operate the doors with just the RPI?

I found the installation and service manual: http://www.assa.se/Other/Entrematic/TechDoc/Installation%20manual/EMSL-T%20INST%20MANUALS%20120223/1006278-EMEI-2.0.pdf

Awsome, loads of good info so after reading loads of this in detail It looks like most of the controller board is actually a power supply and it is entirly possible the controller is still OK and only the PSU section is blown, if this is the case, it may be relativly simple to replace the power supply Have you been able to measure any voltages on the controller ? the one thing that stands out on all of this is the safety compliance, if your going to build a PI version for fun thats one thing, if your going to put it into a commercial building / appartment / Store then it MUST be certified and compliant with local code etc, to not do this could cost you dearly with insurance etc Most of the components look like there either 24V or 40V (Motor?) so the actual interfacing to a PI would just require a relay board probably Do you know if the other modules are OK, after the surge hit? Are the units still installed, I am assuming so based on the pictures, how are you operating the doors right now ? What is your skill set ?

Yes I've sent the controllers in and they are totally fried. To many parts damaged. They accumulated sea air deposits and eventually became one circuit! I am aware of the safety compliance and will be using it commercially so i need to make sure i program it the same way it operated before. I've got more than basic programming skills but am not a pro. I also have basic electronic skills but av enough support from a pro locally. I've got two doors with working motors and modules without controllers. I had one controller in working order as seen in pictures which i swapped with the blown controller on a more important door. The 2 doors that is not working is not so important. I have the time to repair and program the software besides there is so much support online.
