Wiring 2 points to one switch

#1

Post by dtb » Sat May 11, 2019 3:35 pm

Please can anyone point me to a wiring diagram for wiring 2 peco pl11 surface mount point motors to one switch.

I have successfully wired 1 set for a loop but I am having issues with the other that I am unable to get them to work in conjunction with each other. When one opens the loop the other one closes, obviously something to do with the wiring but it's got me scratching my head.

Thanks

Note this may be relevant
On the pl11 the green wire is the return, the set of points that are correct are connected to this as are the other set. Both red and black wires from the problem pair are connected to a point under the baseboard as it is as short loop and then only 1 pair going back to the switch - and I'm thinking they should be run separately .

Sounds like you need to reverse the black and red wires of one of the point motors, the one that goes the wrong way.
I don't model anything in particular, I just play trains.
Why can't people spell "gauge" correctly?

I have always wired points with the tag and probe method so no matter how many duplicate panels are wired up, the results will be the same. A CDU is preferred for this method.
A momentary or a passing contact switch should not be too much of an issue unless one relies on a visual indication of the switch position to work out which way the points are set. (With the tag and probe method that I adopted, one would change every point on the route regardless and it was quite quick to do this, even with the 46 points I had on my last layout, as a route would only mean a few points changed. I didn't need a visual indication to do this).

Thanks Rog that seems to have sorted the issue,
Why would I need to reverse on this set of points but not the other?

@MG I would have no chance at doing that, I can't even manage a set of points :? :roll:

Possible cause is the two motors face the same way. Especially noticeable if on a cross over pair of points (Normally they face opposite directions)
Red and Black arrows show movement associated for each wire (red and black) when being energised.
