Default Peco Point Motor Wiring Problem

Hi,

I have wired up a PECO Pl-10E point motor to one of the momentary contact Peco Switches. However, when I connect the point motor to the power and flick the switch, the point motor makes a small "buzzing" noise, but it does not switch. I have tried this in a test circuit without fixing the motor to the point but the problem still persists. Any tips?

It would help to know exactly how you have wired it.

You need to use the 16 volt AC terminals on your controller. You cannot use a DCC controller or a DC output.

To understand how to wire it, hold both wires from the 16vac output and touch the contacts on the motor either side. The coil will energise. That's how it works. Easy once you get the hang of it.

I wired it to the 16V AC output from my bus wire. The bus wire is fed from my Signatrak ACE 2 DCC controller. I wired it up exactly as the PECO instruction sheet said.

It would only work that way if the PM is fitted with a suitable decoder. Without a decoder you will need a separate 16v ac supply and a CDU.

Hi
Looking at the manual for the DCC unit it does not have any separate 16volt AC Auxiliary output which could be used to power a non DCC operated solenoid point motor.

It reads as though you're trying to operate the point motor from the DCC output. This is not recommended. If you want DCC point motor operation you need an accessory decoder that provides a pulsed output and is installed between the DCC bus wires and the point motor coils.

For conventional (Analogue) operation you should use a totally separate power source for the point motors. The 16v AC uncontrolled auxiliary output from an old train controller (if it has one) is ideal or a totally separate power source providing 16v AC at around 1.0Amp or greater current. You can even use a 16 v to 21 volt ex laptop power supply to feed all the point motors. Keep the DCC bus pair totally separate from the supply and wiring for the point motors when using Analogue operation.

The other alternative if lever or switches are to be used is to obtain an accessory decoder that allows the addition of point levers or switches as well as full DCC operation. One such is the DCC Concepts ADS-2sx or its larger brother with more outputs the ADS-8sx. Note the 'S' in the title which denotes its for use with Solenoid point motors like the Peco PL10 and PL11. Example... Link to Accessory Decoder
