Hello Gents, I just acquired a few temperamental 330a controllers on a new route. I have some prints but am also wondering if anybody might help with any additional info/manuals.

When coming off of inspect all units take awhile for doors to come back. Everything checks out fine with no errors. I get sdoor and cdoor relays. I get SKD1, and SKD2 but not SKD3, SKD4, SKD5, or SKD6 but everything checks out fine. I powered two of the units down at the end of the day last week. Came back the following day and like magic they come alive. (?) Grrrrr.

Can anybody help with a manual of some sort?
