Hi everyone, 
Need some advice for wiring SEEP motors to points for running on DC - seems to be much advice on connecting for DCC so wanted to check with those experienced on this club forum. I will be feeding the point switches and CDU's from a separate power supply to the track supply and I will be livening up the frogs directly so polarity switching will also be utilised via the SEEP.

Below is a typical setup that I can find plenty of on Google search, when I have crossed out the references to DCC  and shown the connections to DC and track supply, which I believe I must have in order for the polarity switching to work. Is that correct?



If that is all correct so far I understand I need to take the DC track +ve & common supply from the track supply feeding into the point - see example below. Will this be suitable feed connection for the SEEP motor point ... even if the DC track feeds are not directly attached at the point?



As the layout is split into block sections, presumably when the block is isolated that includes this point I will only lose the effectiveness of the polarity as the point can still be thrown (in preparation for the next train movement operation once the section is made live again) as it has a separate power supply ... is that also correct?

Thanks for any pointers to clarify.
Paul

Paul, your wiring is good for DC as it is like this

near the bottom of the page

and yes, your last sentence, that too is OK for the wiring concept.

Paul, As Sol says, spot on. 

The only thing different that I do is have track feeds directly to the stock (outside) rails of the point rather than relying on rail joiners to carry the current. My points are electrofrog, the one in the picture looks to be insulfrog.
This is just my personal preference and every single peice of track on my layout has its own feeder droppers for reliability.

Cheers

Marty

Hi Sol ... thanks, as always, for the guidance and confirmations I was was correct. Actually I did read through Brian Lambert's great site (always my first port of call for something I'm not sure of) and assume you mean the item headed as "A similar switching this time using SEEP PM motors."In this case I did see it but was unsure what the D,E,F connections on the point motor did as I could not see that mentioned ... but now I've worked it out and confirmed by you ... it all makes complete sense now.

Hi Marty ... also thanks for the confirmation. My points are all electro-frog and where you see the small green dot is where the dropper is soldered under the point ready to connect to the point motor. I understand your point about every piece of track having a drop feeder - does make sense however the rail joiners I used are pinched nice and tight and I have tested countless times so hopefully I will not have too many issues in the future ... otherwise some adhoc soldering to the stock rail will be called for :-)

Thanks guys and have a great weekend
Paul

Hi Sol ... quick follow up question if I may, based on the DC track +ve & common supply from the track supply feeding into the point. 

I have a section of points (below) that are all fed by track +ve & common supply coming from further along the track not in the photo - indicated by the yellow arrow. From an operational and the block section perspective I require this suits my needs but to feed these 3 point motors with track +ve & common supply for polarity it might appear as unnecessary extra lengths of wiring adding to complexity under the baseboard but wholly doable. 

Are there any issues of polarity I might run into in feeding 3 point motors in this way if a loco were to run through all 3 points? 



Thanks
Paul

Paul, the black & red wires as per first post photo are unique for each turnout - you can't use the ones past the yellow arrow for all frog switching.
I will do a drawing and post it on here later on.

OK, hope this is explanatory
I used your colours in the main
X1 & X2 are track sections switched on via the panel & I have assumed track 4 is part of a loop and that is why I have shown an insulated joiner near the frog of Turnout C. Also shown are Seep terminals CDE for the frog connections.

Terminals C on all Seeps is the same as X1 and you may wish to daisy chain terminals C back to X1 to save wiring to rail adjacent to Turnouts - your choice.

actual connections from rail to terminals C & D will depend on which way the Seep is fitted - may have to reverse wiring on  C & D to overcome short circuits.

Thanks for this help Ron (sorry for using the userid of Sol). Your assumptions we pretty much spot on.
I believe I understood correctly and as I like to picture this in my head quite literally in terms of my layout I produced the following interpretation. I adding in all the insulated joiners which suite my operational needs and are based on the design Trevor helped me with. 

   

Following your explanation, I can daisy chain the red +ve from the SEEPs (broken red lines) for this section of points to the far right track feed (X1 on your diagram) ... OR I can directly wire to the track at the entry of the points, following my early reference photo. All correct? 
I assume I have no other choice and have to attach the black (common) direct to the track as indicated .... and also as you said, may have to reverse wire C & D as necessary as I see that my red and black track feeds in real life are opposite to your diagram.

regards
Paul

Sorry Paul. I drew the turnout formation wrong and thus daisy chain I suggested will not work. In your case, I would not daisy chain and just connect CDE direct to turnouts.

And I have no problems being called Sol, that is my nickname used by my modeling mates here in South Australia

Ok great, thanks Ron.
I assume my suggestion of connecting the point motor to the track at the entry of the frog / point (even if its slightly on the previous piece of track to the point, as per my images) will be fine ... and not as you drew it which I also assume was for clearer explanation purposes only and not to be taken literally?   

Happy for anybody else to confirm that whilst Ron sleeps :-)

cheers
Paul
