Wiring a peco code 100 3 way point

#1

Post by Richard » Thu Aug 15, 2019 1:44 pm

Hello there.
I have a peco code 100 3 way electrofrog point at the entrance to the fiddle yard. Powered by cobalt ip analogue motors. I’m trying to work out point motor wiring. DCC concepts advice from their website is that a AD-2fx accessory decoder is necessary to avoid ‘illogical’ route setting. However the diagram in Brian Lambert’s book and website doesn’t include such a device with peco point motors. I’ve tried to relate his wiring diagram to using cobalt ip analogue motors and am dismally failing. Help please.

For frog switching I would use the change-over contact on each Cobalt ip.

Use this drawing Image and substituent D. E & F for Cobalt 7, 8 & 9 so as ... F becomes 7 while 8 & 9 are D & E, but you need to be aware of which way the point and its motor is positioned as 7 makes connection to either 8 or 9 depending on motor position.

Thanks, Brian
That’s helpful except that the Cobalt connections aren’t numbered like that.
They are from left to right -
DC in
DC in
FB/Led
S2-L
S2-R
S2-C
S3-C
S3-L
S3-R
I imagine that you are referring to the L R and C terminals?

Correct Richard. C = Common so equates to F in the drawing. L & R for Left and Right (hand track).
Most people are shocked when they find out how bad I am as an electrician

As I read the OP, it is not the frog wiring but the motor wiring so that the correct motor works first on the Code 100 3 Way ( which is different physically than the Code 75 asymmetrical version ) without using what DCCconcepts suggest being accessory decoders.

If this is the case, then I would contact DCCconcepts and ask them.

I know using peco solenoids, one can use a diode matrix to make sure tiebars work correctly but here is a site for stall motors

How are the two analogue ip motors to be operated - DC or via DCC?
If DC, then two DPDT switches are used. The first or front end switch operates the front point blades while the second operates the rear (nearer frog) point blades. By always ensuring the first (front end) switch is set correctly and then the rear switch is set, the correct movement will be maintained.

The DCC Concepts manual shows both numbers and letters for each terminal... See extract below

Also don't forget due to space issues under the 3 way point one motor will be reverse fitted to the other (180 degrees around) as there isn't room to fit both facing the same way.
