Home Forums General Discussion Technical Questions Amtech Reliable Door Print

I seem to be missing the print that shows the power door card and door operator. I have a Traction job under 200 FPM. Any help with a drawing would be much appreciated!

MOD?

Yes!

Taking out F8 Fuse when power is applied. Suspect the board but have no information on this circuit or how it operates? This looks a bit different than a regularly used open and close relay!

Just sent you something. First check the caps in the controller! Should be 2 uf caps in series. Common failure that blows fuses, and not always immediately. It's pretty simple though, you can test and replace the components on the board. Just don't overlook the steering diodes that they add in the MOD box itself.

Are the capacitors in the lower part of the cabinet by the board? And are the steering diodes in the operator? Looks like maybe the SDO/SDC cams? Thanks for the information!

Caps are usually in the top right corner of the controller, they're about 1" dia. X 5" long, usually blue. The diodes are in the operator to make the MOD work with the solid state board.
