Trying to install a Peco PL10 switch machine motor to a Peco wye. The turnout works fine by hand, the motor works when powered up, but when I attach the motor to the turnout all it does is hum. It cannot move the points unless I help by hand. I've tried two different motors and the problem is the same. Didn't think this would be such a complicated install.
Could be wiring or as Dr. Gonzo pointed out power source. Check to see what current AC or DC the motor is supposed to operate on. You may need a DPDT reversing switch to actuate the direction the switch points throw. Just a note some switch machines or solenoids are on and off while others are constant on. So check these things out. Again, back to the instructions that came with the switch machine.
I'm using the 16V AC outlet on a transformer, and Atlas #56 switch control, just as I do with my Atlas turnouts. The Peco instructions are pretty minimal, but indicate using 16V AC and a momentary switch. So the machine works fine on the bench, I don't see anything out of alignment with the turnout (it's been working fine on the layout), but the switch machine just cannot move the points when it's energised.
Forgive me for being all of a suddend dummyified and scratching my head. From what you described, you are doing all the right things and have it set up correctly. If you can get it to work off the layout and it won't on the layout. What the hell? Sorry, but you got me on this one. Unless...just a intelectual guess...(ok that's my medications talking). Check to see if the throw is not connecting correctly between the motor and the switches throw bar. Look to see if there's to much slop. Then get back to us.
Sorry if I confused you there. The turnout worked fine on the layout, manually. But it won't work using the motor. I've tried it both on the layout and off. I've tried using a brand new motor. No luck. It is as if the motor is not strong enough to throw the bar. I must be missing something here. The throw rod simply goes up into a hole in the throw bar, and you clamp the motor to the ties on the turnout. Seems simple enough. Guys have been using Peco for decades so it must be me
When the motor is installed, can you manually still move the throw bar freely? Almost sounds like something is binding.
So, when is 16 volts not 16 volts? Problem solved guys, and thanks for helping me eliminate the possibles and drill down to the obvious!! After sleeping on the problem, I decided this morning to put my meter on the powerpack I use on the bench. Not quite up to snuff. So I connected to my old MRC Tech II and the turnout works like a charm. Amazing what a stray volt or two will do huh.
Whew, glad I could help you fix it. LOLOLOL Well, maybe not but at least you solved with your intuitive and deductive reasoning. Nicely done.
Sorry for the late reply, but you also have (had..) to make sure that your transformer is able to supply the needed amps. Too few amps and it won't throw the point. I know because I ran into that once. I'd also suggest to spend $20 or so on a capacitive discharge unit (CDU) which will give your PL10 an extra boost of juice to throw it. Well worth it, and you only need one for all your switch motors. Kyle.
I had a similar problem, got the capacitive discharge unit and it seemed to solve the problem. ("seemed" because I only tried it a little before my layout got buried in a family history archive project...)
The capacitive discharge is also a good safety item also. It will give the good burst of power when actuated and no more power until it is released / you lift finger off of the button. this will prevent burning out atlas switch machines and probably peco also when the button is accidentally held down by a tool or a guest. I have used one for probably 15 years. Originaly it was to supply adequate power for multiple switches on one button.
Good suggestion Kyle, thanks. My intention was to use a transformer to supply power to just the turnouts and perhaps layout lighting. Clearly I chose the wrong transformer! I have a mix of Peco and Atlas turnouts, so will one CD unit be compatible for all?
