Now we have a fully assembled controller board and a capacitors board with all C's on it, connected to each other and connected to the communication board, we can test some more functionality of the combination.

I already tested the:

- C2,4 and 5 and the related relays

- External relays

- Frequency input circuit

- EEPROM memory for a few locations in the memory

- The complete data input train into the shift registers of the driver IC's

- All CLK signals

- All Strobe signals on the driver IC's

All is proven OK.

I further want to test:

- Functionality of all other C's and relays

- Check of all other /OE signals

 

Well, the bad news is that I blew a micro controller. I dont know why, but I think I touched some wrong wires during testing previously. A few /OE's did not come out of the micro controller, so the relay drivers were not activated, and the relays stay quit,...

The good news is that I programmed a new controller, and installed it.

In the mean time I finished the inductor PCB and decided to put the whole thing together.

I powered up the complete setting, and started the PCB app.

Again good news. All relays were working, the C-relays, the Inductor relays and the special ones. Also the external ones were clicking. So all the /OE-signals were there.
