LED's to indicate direction
« on: May 24, 2018, 12:07:48 pm »
A little advice please. I have laid the track-Peco code 55 and Electrofrog points.The servos have been installed as have the Tam Valley Depot Octopuss 111 servo drivers. I have connected Toggle switches and the points switchas they should. But I am having difficult in connecting LEDs to indicate direction on the
control panel. 
Can someone please throw some light on this subject for me ( no pun intended), as I am only starting out at the age of 72 perhaps I am being a little ambitious.

Regards to all,
Bobbyvabc

I'm not specifically familiar with the Octopus, how have you got them set up? It looks like if you use momentary contact switches then you can use y-cables to use LEDs, if you're using toggle switches then you need DPDT and use the additional pole to control your LEDs (or frog polarity).

You need DPDT toggle switches.  One side of the toggle pins goes to the Octopus, the other side (pole) goes to the LEDs.
The centre pin is power in (or out); each of the other pins goes to the LED to be lit.
I would suggest wired as :
DC Positive wire - resistor - centre pin - leds - ground

Supply voltage used will dictate the value of the resistor needed.

OR you could use their push button board which has two indicating LEDs attached (easy to unsolder and make remote).

Hi NinOz,
Thank you, Do you mean deconstruct the Tan Valley push button board and reconstruct on the control panel.

Reading their literature suggests that's not necessary - you can use a y-cable (if you're using momentary switches), with the switch on one side and the two LEDs on the other side.

Exactly.  Would allow separation of the LEDs and push button only if you needed to and didn't want them tightly grouped as supplied.  Although their panel mounts look very nice.
The only "problem" with the push buttons are that they are position toggled rather than sort of direction indicating like a DPDT switch but then that is what the LEDs are for.  Personal preference really.

Of course they have the option of having more than one duplicate panel connected to the same Octopus.

PS: since you have it setup and working (hopefully with DPDT switches installed) then adding a couple of LEDs per switch to your panel would be the approach I would take (less time and cheaper).

Just a further thought.
If you have SPDT switches and don't want an independent power supply for the LEDs then the following may work (I am not sure of exact wiring for the Octopus inputs):
Red wire - resistor - LED>| - signal wire (usually yellow or white) - LED>| - resistor - Black wire
Just connect at the three terminals of the toggle switch.

 Hi NinOz,
Today I purchased some FCB021 R/G Fascia Controllers, plugged them in, all works perfectly (just like a bought one). The arrangement of the push button and the LEDS is fine with me as the control panel was a mock up and I can easily reconfigure to suit. Thank you for the great advice leading me in the right direction.
Regards
