Wiring point motors with CDU capacitor

[Frankie2]

Hi folks, I need help wiring my points using a CDU, not done any before. The CDU has input 1 and input 2,  then out positive and out negative, pointmotor is peco pl-11. The green wire goes to OUT -from motor to CDU and the red + goes from toggle switch to CDU + is this correct. The black from the motor will then go to toggle switch negative. Bit where I'm confused is that my twin gauge master controller has 2 ports both negative marked points, and then AC port marked negative. So do I connect the CDU to the points port or the AC ports or both and to which input on the CDU. I'm sure it's a simple process but I keep getting confused, as I have to diagrams but each use different coloured wires. As a novice I need some guidance in layman's terms. Regards Paul

I have used the Peco PL-11 colours Red Green & Black in this diagram as well as using the terms you have stated for the terminal labels used on the CDU. My wire shown in grey, is just a colour I have plucked from the air. The grey wire could be any colour of any wire that you might have available. My diagram just shows what connects to what with the grey wire. The toggle switch has three terminals, a middle terminal and two outer terminals, thus my drawing shows the wires terminated relative to those three positions on the switch. Since you are using a CDU, then use the 16 volt AC output as labelled on the rear of the GM twin controller as shown. Again the CDU to Controller black wires in my drawing are just an arbitrary colour I have chosen for the drawing.

If you have more than one point, then the other point motors and switches are wired exactly the same and connect back to share the vertical wires dropping down from the CDU drawn in grey and green with the arrow heads on them.

Thank you chrissaf that diagram is simple and self explanatory. I don't I'll have any problems wiring now. Cheers .

Chrisaf ... would the same wiring layout be suitable for Seep PM1 motors using cetnre sprung off switches?

[Chrissaf]

Any & all 3 wire solenoid point motors can be wired the same way. But note this, if using Hornby R8243 & R8014 point motors the wire colours on the Hornby motors are different. Hornby use black as the common return, not green (Peco), so the green and black point motor wires in my drawing would need to be reversed for Hornby motors. But apart from that, any 3 wire point motor can be wired the same way as drawn.

.

With specific reference to SEEP motors. The red wire in my drawing would connect to A on the SEEP, the black wire to B and the green wire to C.

Note: I mention the Hornby colours above more for others who might be reading this thread in the future. I wouldn't want them wiring up their Hornby points to my Peco PL-11 drawing wire colours.

Many thanks Chrissaf. Appreciated
