Point points to a control board (Wiring, LED help )

[ashleeey1990]

Hey! 

 

I want to wire a control board for my point motors on my model railway but I can’t figure it out in my head what to do next when it comes to LEDS and how i will visualize it - which is my next step - so any help to aim me in the right direction for the process and information I need will be fantastic!

 

I have bought the Block signalling Points Position Indicator PPI4-DC- which at first looked great – but as it only comes with one set of red and green LED lights I just cant picture how this would work on a track map layout as when you switch the point motor surly the green light should red and the new road red light turns green ( requiring 4 LED lights to one point motor and not two)  >_< am I just over thinking any wiring information would be appreciated thanks a lot

 

i have added the point motor wiring diagram and my track plan layout

I thought ill add some pictures of my layout as it currently is and an updated diagram

 

even help on where and what and how to connect all the wires up with what sort of clips will be help

 

I eagerly await a response.

The wiring looks pretty straightforward, I would be inclined to use 3 or 5mm Green LEDs with the appropriate size bezels to attach the LEDs to the track diagram.

I would say two LEDs per point are all you need, which ever LED is lit that is the route that is set.

 

Just the way I would do it

It sounds like you need a lot more LEDs wire the Green LED as per the instructions but wire a Red LED in parallel on the other track of the mimic diagram.  Wire a further Greem LED as described for the RED LED and wire Red LED in parallel but on the other route of the mimic diagram.  This way the route set should turn green and the other route go red.   You will almost certainly have to use extra resistors on the Reds as they glow very much brighter than the greens when fed through the same value resistor.

 

I would buy a few feet of plastic trunking to hide those straggly wires and screw connectors before your cat/dog/foot gets hooked in it and rips the lot out.

Thanks for the info - i found some dual red/green LEDS that should do exactly what you said - just currently nailing in all the track - Here is a video:

Work is progressing on my control board - Im using a Blocksignaling PPI4 for the LED lights - yet sadly with these dual Red/Green LED lights the Red part is not as bright as the green - maybe its the leds themselves? may have to look at something different on ebay. wiring is getting complex with 3 points and 2 led lights wired up already. Fun times ahead.

 

here is a short video of how things stand at the moment:

 

 

Thanks

I'd add an extra resistor in the green LEDs circuit to reduce the brightness. You will have to experiment to find a suitable resistor value.

There pre wired with resistor LEDs, I don’t mind the brightness of the green - just a shame the red LED light don’t output with the same brightness

I used 3-legged bi-colour red/green leds for my indicator panel. On the crossovers I had one led in each parallel track and one in the crossover leg, such that there was a green on the straight and a red in the branch and vice versa to match the point direction.

 

An advantage was by matching resistors to forward voltages of the red and green Side of the leds I could get a yellow if one of the pair of crossover points failed to throw, hence both sides of the leds were powered at once.

 

This methodology also cuts down on the number of leds you needed.
