I'm really hoping someone can help me with a set of prints for this thing. It's a 1969 Montgomery hydro with manual freight doors and a 2 coil Montgomery valve. I have a lot of old prints but can't find anything with similar enough terminal numbers to put a meter anywhere. Anything even remotely close to identify safe, door locks, & gate would be greatly appreciated.
So, I have seen tanks like this in confined type spaces. You do have a Montgomery there. Have you tried Spares with the job number? I have looked and have nothing similar at all.
I have not, you think that serial number off the cross head data tag would work? I did end up finding 3 prints that are similar. They have a K relay for doors closed anyway, the terminals are all C3, C4, etc but maybe if I ignore the C. My problem is simple, there are no relays picked in the controller except the alarm bell relay when you push a hall button so probably safe, door locks, or gate. This may be enough to go back with but I’d feel a lot better with a print that matched. I thought maybe Montgomery had put their name on another manufacturer’s controller that someone might recognize. I’ve seen US IBM relay controllers that Montgomery painted dark grey and put their name on.
Montgomery almost always had a C before their job numbers, but this could have been an earlier controller. These relays look like old Haughton Hydro relays. I must say you always come up with interesting problems.
