Hi chaps, I have cleared up the house and garden in preparation for the thin controllers return from UK and can turn my mind to the railway again.
I am sure we have an expert out there who has access to published information or already knows the answer to my query.
I have several LGB signals with motors (they seem the same as point motors) and would like to use the output from a supplementory switch on the points to operate them.
I will need a seperate power supply to them I imagine but how do I wire them?

Your answers on a postcard please

Sorry Geoff I meant to send you some info, but when I checked with my book it only covers EPL non mts circuits. What it does say is that the signals are operated by momentary contact switches and I donít think the supplementary switches for the points are. So something more ingenious will be required unless the switch decoder has such an output, which thinking about it, it must to operate the point motors. So just wire he signal motor as if it was a point working in unison, and it should repeat the point position.

Hi Geoff

I can't help Embarassed but why not PM Jeremy or hope he picks it up via this thread?

I know the Navigator can only operate one switch decoder assigned number at a time, I'm not sure if the power output from the decoder is enough to operate two EPL devices simultaneously?

No need for power supplies and all this Mammoth m'larky... Evil or Very Mad

You could wire them directly together very easily!

If they're in a straight line it would be better otherwise you will need some angle cranks or some wire in tube or bowden type cable would work well too. Basketball

Luddite, next thing you'll be wanting to run locomotives with primitive steam like in the dark ages.

I was going to make some comment about Luddites and Cotton Mills, but I better not.

Geoff I have checked with my instructions for my 55025 switch decoder. It says that each output can take 1500ma and the unit itself 3000ma so that is quite a bit. I donít know what a point motor takes but will check with Jeremy on Monday but I should not think that it is anything like approaching 1500ma

A single output from the 55025 can be used to throw several point/signal motors at the same time but I would not attach more than two.

Thanks Mark, that's useful information and I will pass it on to Geoff who is off-line at the moment.

Let us know how you get on Geoff and if it works successfully.
It will be good future reference...even for the Luddites. Rolling Eyes

Oh....and keep those chickens away. Laughing

To confirm my previous post, taken from the LGB 55025 manual...

Quote :

Current draw.
The LGB Switch Decoder needs about 20 mA current
at rest. Each terminal can handle up to 1500 mA.
The maximum current on all terminals is 3000 mA.
Each terminal can operate a maximum of two switch
drives.
