i am ploghing my way through sorting out the Electronics bits I have prior to listing them. However I Have lost my Book that shows me how EPL points are wired up. Plus I wish to use the LGB Switch Boxes to to it, plus also to prove that they are OK. I also have what I believe to be an EPL Point Booster the Red Box. I should be able to do all this butbit is now so long since I wired up any LGB Points that I appear to have lost the nack! Certainly my Air system is much easier.

Can anyone please show me a Wiring Diagram that clearly displays how I connect the 50110 Transformer via the Switch Box to a Point Motor please?

Brilliant Dan that was definately the page I needed. Able to Test out Point Motors and the 51750 Switch Boxes perfectly now.

Now only to figure out the 52750 which is the red one with no Switches.

As I remember rightly (I had EPL) it is wired directly to the 16v non-controlled output of the transformer, you then sit it next to the switch box with the pins in the holes of the switch box. It is only a high capacity discharge unit which basically gives the point motors a kick up the bum rather than a longer lasting pulse.

Thanks Mr P, kind of what I was thinking it may be, will give it a worl.

You are very welcome. Oh, wires, did I forget to mention EPL and all the wires? :eek:

Not sure it is actually a booster Pugs - just a timer/switch box. Certainly mine never was. Boosters are more usually used on solenoid type point motors whilst LGBs is more of a traditional motor (although only ever making half a revolution). On this motor a booster current would possibly expire before the motor had completed its turn.

I am away at the moment, so can't dig out my 53750? EPL booster to look at the connections, but as I recall there is a definite 'in' set of terminals and also an 'out' set.

I wired mine up to supply both a yellow and an orange control box so the EPLs all got the boost whether I was controlling them manually through the orange switch box or automatically through reeds that were switched on and off by the yellow control box.

There are three LEDs on the face of the box - the orange one shows the AC supply is on and the red and green light up when an EPL is doing something.

One light relates to a half wave + demand the other to a half wave - demand.

A marvellous little box of tricks.

I am confused. The 53750 is a delay timer unit, why is it being used as a booster - or has LGB produced two different items under this part number?

I believe that the unit in question is the 52750 EPL Booster. Mine is powered by the LGB 50110 AC 5 Amp transformer. The set up is as follows: Transformer to 52750 then 51750s daisy chained to the 52750 using the built in side connectors. I forgot to mention that the 51750,52750 can only be used with an AC input.

Here with an extract from LGB Instructions for the 51750

Applications
The 51750 can be used to control LGB EPL devices, like switch drives, signal drives and electric uncouplers

Connect one set of white and orange terminals on the 51750 to the matching white and orange terminals on the EPL device.

Hints - Sometimes, EPL devices need extra power to overcome mechanical and/or electrical resistance. The 52750 EPL Booster will provide that extra power, and we strongly recommend it for reliable drive operati-

on.

- If you want to operate two EPL drives simultaneously from the same switch of the 51750, you must use the EPL Booster 52750.

Installation
Mechanical: The 51750 can be installed indoors or outdoors. The
base plate has four mounting holes. Electrical: The 51750 requires AC power from an LGB power supply.

Power can be connected to the terminals numbered „3" and „4" on the screw terminal strip (Fig. 2) on the rear of the 51750. The green power indicator lamp lights when power is connected to the 51750.

Power can also be connected using the male and female „piggyback" terminals on the sides of the box (With these terminals, several LGB control boxes (e.g., 51750, 51800) can be connected.

Hint: If the male piggyback terminals are not used, they can be removed.

Attention! Do not mix AC and DC power when connecting control boxes.

Yes that is what I was trying to say but non-tech.
Stockers, the timer unit is a different beast and I believe it cannot be used as a booster. It is also easier to find teeth on a chicken these days than the timer unit. The booster unit lasts long enough to operate a point motor fully (without it some of the points only went half way when using the switch box only :eek: ) and it certainly made a huge difference on my railway where most of the points were quite some distance from the shed.
I still have nightmares about the wires :worried:

You have added an extra number Alan, we are talking 51 and 52xxx.

Thanks Jon - got it now. Possibly not for use with DCC!

I use this setup with DCC - Maerklin CS2. I originally installed the EPL equipment prior to MTS2. I have found it resilient and easy to use. I have not got round to installing point decoders etc. Why fix it if it ain't broke?

You are quite right - apologies I got the catalogue number wrong - did say I was away in mitigation! The question mark was put after the number as I was not entirely sure of it:

53750 is the wonderful timer.

52750 is the equally wonderful, (but for different reasons) booster.

However, I stand by everything else I said....

So I figured out what to do with the other box qnd it works the motors with a satisfying clunk. But certainly not for use via a Switch Decoder.

The two boxes are connected in the middle via a couple of LGB fitted pins. The Red one (right) is the Point Motor Booster Power from the Transformer LGB 50110 to the Red Box 52750 on the Right where the 3~4 is. Two wires connect that feom the left of the Red Box where it says 51750 and go to the Right of the Orange Box 51750 (left) where he 3~4 is. Points are fed from the two wires on the left in this case point A. Works a treat and there are Coloured Lamps on the Red Box which indicate which way the switch has been thrown in the Yellow Box. All fiendishly clever.
