Does anyone have experience with wiring one of Peco's Electrofrog Double Slip Switches? Its part #SL-E390F. I need to add the feeders for DCC operation. For some reason, I am stumped on what exactly I need to do and the instructions dont seem to provide a clear answer for me The switch comes factory equipped with 4 loose wires that were wound around the turnout in the package which im assuming are the feeder extensions? Is this as simple as wiring the two left wires together to the same feeder and the two right wires together to the other feeder? Or is there something else that needs to be done? Also, does this turnout need to be completely isolated from track around it? My intentions were to solder each connecting track to this turnout to achieve flush rail connections since I am mating with Atlas Code 55 and these peco's are technically code 80 rail. Thanks in advance!
I'll jump in here and hopefully others will also and there are probably YouTube's and other sources out there. Looks like each wire controls 2 adjacent rails. The polarity of those rails needs to change depending on the route taken. Personally I don't see where any of them could be tied together and not result in a short. I also see non-insulated rail joiners on the short sections of the frogs that will connect to the adjoining track. I can't see how they wouldn't need insulate rail joiners there and the the wires that go to the frog on the other side of the frog point would also need to go to those short sections. A VOM would quickly tell you if they are connect. How are you controlling the double slip? Which point motor? One way to control them and probably the best is with the point motors and the electrical switches/contacts they have or a combination of the point motors and 2 frog juicers (such as Tam Valley). I don't think you could use two sets of frog juicers (4 frog juicers) at the same time as they might fight each other. If you used Tortoise point motors (2) I believe you could also control them with nothing else but I don't have personal experience with them. A good source of info for this is ( HERE ). If you use something like a home-brew servo control like the servo mounts I have that one can print if you used two of the ones with two DPDT limit switches on it that would probably do it. Or two servos & mounts with a single limit switch and two frog juicers. There are a number of options but I think you are going to have to study something like the DCCWiki link above to get a better understanding if this is the first time you've come up against this. I saw a number of YouTubes doing a search ( HERE ) but didn't view them so that might be a good option if you don't get a better one on here. Sumner
Sumner, first off, thank you for taking the time to reply! I really appreciate it! I did watch a couple of those youtube videos and just finished reading the page you linked. I now know that the two center wires are the +/- and the two left/right wires control the frogs on either side. That is pretty straight forward and I understand that now. I also have since taken the metal rail joiners off, and have ordered Micro Engineering Code 80 to Code 55 plastic transition rail joiners for all these double slips and double crossovers. Unfortunately I am at a standstill now as far as mounting the turnout and any surrounding tracks until those arrive. But I still should be able to prep its wiring for the time being. My intentions are to use Touch Toggles Servo Control units to power plain and simple SG90 servos. I did this on a small diorama a little while back and really liked how they worked. I ordered several hundred dollars worth of Touch Toggles items a little while back, so I would like to keep rolling with their products. Eventually I will make control panels using picture frames to mount the touch buttons for each turnout. If I am understanding this correctly, I need to use two servos correct? After reading and watching the videos, I understand that the left throwbar controls the right switch points, and the right throwbar controls the left switch points. That is something I will need to remember when hooking up the servos and setting them up. Ive never powered a frog on any turnout in any scale so I have absolutely zero experience with using DPDT switches or frog juicers. Ive always just let the track feeders provide the power. But this wont be the case on these double slips since they will be completely isolated with insulated rail joiners. Is this something that can be powered by the Touch Toggle servo control unit? Or does this need its own power from the track bus? Either way, that does not sound too complicated. What I am unclear on is how to link up the servo and DPDT switch to ensure the power is routed in the correct direction when the point is thrown.
Couple things and double check this: 1. You only need to isolate the rails going to the frogs with the insulated rail joiners. My comment about changing the polarity of 'all' the wires in the picture I posted is wrong , only the frogs need the polarity changed), 2. The outer stock rails don't need to be isolated. 3. From what I'm seeing wire the middle wires to the stock rail that is next to them but I don't feel comfortable saying do that for sure without having one of the double slips in front of me. 4. You could use a DPDT switch for the frogs if you wanted but since the frog juicers aren't that expensive I'd go that route. or.... 5. If the servo brackets allow you to mount a SPDT switch on them you could use that. Looks like the Barrett might not allow that. Mine and others do. Since I don't have the double slip in front of me to check with a VOM I think I'd better not go on as it might take you down the wrong path. Sumner
Try to polarity opposite frogs. Left frogs to right wires. I don't have my wiring diagram, but it works I wired both versions: single slip, double slip and both works fine
