Thanks bearwhiz. This place has already proven to be quite a helpful community. I had imagined myself being all alone in this quest. I should double check the safety cable loop with a meter. I presume I can do this at the back in the electrical panel by checking continuity between wire 16 and 56, where each end of the yellow wire loop terminates. There is a lot of corrosion all around and perhaps they aren't making contact. Inside the control panel I did not see Allen-Bradley. There is a board on the left that says Varispeed 2000. There is a bank of relay sockets in the middle and a larger circuit board on the right. The control panel is a lot of switches, mostly rocker or toggle. It does not have a touch screen. There is a small LCD that might be a counter, but I have yet to see it light up. I tried to locate the programmer. I'm not sure that I saw it. There is a curved cover between the motor and a gearbox. A wire harness seems to run into it. There is also a small chain going into this assembly and it seems to attach to some pieces that engage part of the carousel. A few other notes that may be important: Some of the switches on the control panel are clearly broken. #2 will not click into the on position. I think #7 won't move at all. Some of these switches light up, most of the don't. Maybe just bad LEDs inside, I don't know yet. I still have significant air leak problems. Only 5 heads are hooked up, the rest of them which are even more broken down, line the wall. There is one head that goes up and down well. All of the others dump a bunch of air either when up, or when down. I took apart one of the solenoids and looked it over and inspected the spool. Maybe the O-rings are bad. I'm not sure how sensitive they are. Normally I would say they're fine. I put it back together and it is only a tiny bit better. Would air blow-by be restricted to the solenoid, or could it be happening inside the cylinder and making its way to the vent port in the solenoid? The same solenoid module is installed for the high-lift cylinders. One of them is slow. It works, but it dumps a ton of air before it gets set. The same solenoid module controls the flood / squeegee carriages. Haven't gotten very far with that. There is another solenoid that controls the fork. This leaks a ton of air. There was a fuse with a broken ceramic casing in the control panel. (On the Varispeed board) When I pulled it out to match up a replacement, the bottom half of the fuse holder pulled off the board. I attempted to remove the board so that I could properly solder it back in, but with the screws removed the board still wouldn't come off. I could not tell if it plugs into something behind it or not. I didn't force it and gave up. I think this still needs more proper attention to see if it is making contact after my half hearted attempt to re-affix it from the front. The belts that move the squeegees are in poor condition, but mostly they are way out of adjustment. I think I can handle these via the access hole on the side of the assembly. I think that's about it. | ||
