Re: Power source for turntable motor

DanielW <danielwatkins1953@...>
 

It's the Walther 90' Built up Cornerstone series, model #233-2840. This is the fairly expensive turntable, not the cheap build it yourself one. One set of leads are brought out for the track power and another for providing power to the motor. The controller has positioning capabilities for programming up to 60 stopping spots. It will accept either AC or DC. I'm not locked in to using resistors, just what the tech person at Walther suggested.
I just want to be able to reduce the voltage output from my transformer to a usable safe level for the turntable motor. I'm open to all ideas.
Thanks,
Dan

Soon plan on converting the control for my turntable to DCC but need to establish a power source for it first. Tech people at Walthers suggested I use my old Throttle Pack transformer's 16v AC outlet for this purpose. Trouble is, although it's rated at 16V, it meters out at 22V. The max for the turntable motor, and it's existing controller device is 19V. Ideas about what size of resistors and how they should be wired in to reduce the voltage to an acceptable and safe 16-18V range?
I know this isn't a DCC specific question but since everyone here is knowledgeable and friendly I just tend to turn to this group for help.

Re: Wiring a Tortoise to a Lenx LS 150

Hi Max

Well that was easy thank you.

So the Tortoise gets it's power from the LS150 which gets it's power from the Auxiliary bus AC using the two diodes and is connected to the track bus for the Lenz system, correct?

Re: Crazy Eight that Double Slips

Vollrath, Don <dvollrath@...>
 

There is the equivalent of a wye where each of the center legs of the figure 8 merge into the outer loop. Isolate the straight portions of the outer loop parts of the wye. Both of them. Turn those tracks into 2 A-R controlled reversing tracks. The whole figure 8 including the double slip crossover can be all the same fixed polarity.

I am in the process of building a N Gauge door layout 32x84 that has a oval around the edge and a figure 8 in the center with a Double Slip turnout at the center of a figure 8, with a crossover (Right Side/width Side) to access the figure 8 in either direction. The question is where would be the nost effective place to install the reverse loop section of track on the eight with the least amount of wireing and reverser s?
Should it be just on the turnout? (Slip Turnout)

Should it be on the left side opposite the crossover

Should it be on either side of the crossover (access to the 8)

or should the whole figure 8 be a reverse loop?

Re: Reverser Yard

John Roth
 

Mike -

We went KIS. We replaced the whole works with a reverse loop and handle yard/staging on an entirely separate module. This was easier to wire and maintain, and got rid of all the weird corner case anomalies.

We thought about trying to create a smaller section under PSX-AR control and having the rest under a specific phase. We opted out of this because we kept finding ways to short the PSX-AR section if the section were shorter than our "longest train".

Re: Reverser Yard

Vollrath, Don <dvollrath@...>
 

There is another way that doesn't need an auto-reversing unit for tracks in the yards. 1) Isolate the entire double crossover using 8 insulated rail joiners, and power it through a PSX-AR. 2) Use a DPDT relay to select track polarity of the two yards to be a) same as the track feeder from the main on that side , OR b) same as the feeder from the opposite side main track. 3) wire the relay coil to operate only when the crossover turnouts are set to X-over. Now the yard tracks will still match the polarity of the selected yard leader, but the PSX-AR won't carry or be be affected by power drain in the yard tracks.

Don is absolutely correct - a second train will not cause the PSX-AR to
malfunction.

It would be interesting to have your friend lay out exactly what he thinks
will happen to the PSA-AR when it detects the short from a train entering
the reversing section and reverses power to the reversing section. Once we
know what he thinks is happening, we can help him understand why it is not
an issue.

There's a bind in that mechanism someplace. Run it slowly and look for the

power...if it's the only loco that does it there's a mechanical hang up in
it someplace.

Re: Reverser Yard

Vollrath, Don <dvollrath@...>
 

Mike, re-read my previous answer. The couble crossover completes a wye that attaches to the mainline in two different directions. There is the reversing problem. As long as you vow to never have two trains traversing in/out of left and right yards at the same time (even though it is possible if you set the double crossover to 'straight')... Simply isolate both legs toward the main and make the double crossover and all yard stubs into one giant reversing section. Throw all 4 turnouts of the double crossover at the same time and almost any purchased crossover will not have any issues with that. Doesn't make any difference at all how long the yard tracks are, as long as they are not somehow connected back to the main line at the far end. Trains inside the reversing section will not be affected by A-R polarity reversals.

Let me try this again, I have uploaded a file with a track diagram (perpendicular staging.pdf) The orange and green sections would each have a psx-ar reverser (I know there is a green section on the orange side that is an error in the drawing). The pink slashes represent the locations of the insulated joiners that create the reversing sections.

The yard tracks could be as much as 24 ft long.

You cannot get from one reversing section to the other, only from the yard leads. While it is not physically impossible for two trains to be entering the reversing section at the same time, they will have a collision before a short occurs.

Again, my concern is whether I am going to have a problem because there may be trains operating totally inside the reversing section while a train is entering or exiting the reversing section tripping the reverser.


Thanks,

Mike

this usually happens on turnouts and diamonds, though it also happens right

in the middle of flex track sections with no gaps or visible defects.

other locomotives have no problem with these track sections.



The locomotive is equippeed with an TCS MC2, and i've tried it on both an

MRC prodigy express, and an NCE system, and this issue re-occurs all the

time.

Subject: [WiringForDCC] locomotive hestitates but restarts if i throttle

down



I have a brass locomotive that runs relatively well, but it tends to get

"hung up". Basically, it will stop on a section of track and hum. If i

throttle down a speed step or two, it starts up again, but otherwise it just

sits. nudging it also works, but thats no good either.



this is strange, because for weeks it didn't do this, and ran fine, with no

problems, and it suddenly began to do this, even though i had not fiddled

with it since installing the decoder.



this usually happens on turnouts and diamonds, though it also happens right

in the middle of flex track sections with no gaps or visible defects.

other locomotives have no problem with these track sections.



The locomotive is equippeed with an TCS MC2, and i've tried it on both an

MRC prodigy express, and an NCE system, and this issue re-occurs all the

time.
