Рет қаралды 33,329

Күн бұрын

This video shows how to connect a capacitor discharge unit up to a power supply and a set of points, using a switch to set the points.
It then shows how to connect up a points position indicator to show the state of the points on a control panel.
The parts used are:
Capacitor Discharge Unit: BLOCKsignalling CDU2R
Switch: BLOCKsignalling BS3W
Points Motor: Hornby R8014
Points Position Indicator: BLOCKsignalling PPI4-DC

I was wincing watching you prepare the input wires. The insulation was too short, ideally you should not see any bare wires outside of the terminal block. Your wiring of the points motor into the terminal block was spot on.

Thanks for a super video. My layout has eight turnouts and route switches. How do I wire the remaining seven turnouts and route switches? I don't need to throw more than one at a time. Any help greatly appreciated. Thx.

@BLOCKsignalling 7 жыл бұрын

Which CDU you will need depends on several factors, the number of points you want to use at the same time, the distance of the points from the controller, the wire size, the voltage and capability of your power supply, the gauge of the layout and so on. For a basic, compact layout, where you only want to operate one or two points at the same time, then a CDU with a single capacitor (4700uF) will be sufficient. For a larger layout, where now or in the future, you may wish to operate several points at the same time, and these may be some distance from the controller, then a CDU with two or more capacitors is recommended.

One question though: for the 2nd solenoid motor, where would I attach the LEDs? Would both the positives go into output terminal 2, and then 1 of the negatives into C1 and the other into C2? It strikes me that C1 and C2 would get quite crowded if that is the case. Thanks.

Thank you for your excellent video. I have wired up 4 points with LEDs. I have a problem with the lights though. They work when the trains aren't running but when I run a locomotive they flicker and go off and then on again. I've checked the connections best I could and they seem ok. Any suggestions?

@BLOCKsignalling 2 жыл бұрын

Sounds like you loco is pulling down the voltage of the supply to the PPI, causing it to reset. I would try runnig the PPI off a 9V battery for a while to see if it eliminates the problem.

@grahamebelton9832 2 жыл бұрын

@@BLOCKsignalling I think I have found the problem? Not sure though. Bad connecting on the points themselves. As the train goes round the track somehow it affects the blades on the points and this causes the LEDs to flicker. Can't be sure though, because the problem is intermittent. Can't think of anything else as I have check all connections?

Hello….Help, I have wired two out of three of my ppi’s with everything working well! I had to wire just two more points to the third unit and the points work well. But both the green and red led’s come on at the same time and won’t switch off. These have been wired in exactly the same way as the other two units, so can’t understand what’s wrong!

I have a CDU2C connected to AC power on the transformer. Can I hook up the PPI to the CDU output? i.e. is the power output from the CDU DC?

You cannot use the CDU output as that falls to zero each time the points are operated. Please see here for the wiring: www.blocksignalling.co.uk/pdfs/50LF1L.pdf

You said at the start it was a guess getting the black and white wires the right way round. I assume if you’d got it wrong you’d have fried the cdu? So how do you check this?

@BLOCKsignallingUK 3 жыл бұрын

I am very certain all CDUs will be protected against incorrect polarity, as many are designed for an AC input so will have rectifier diodes on their input. If the polarity is incorrect, they just won't charge. No damage should occur.

@BLOCKsignalling 8 жыл бұрын

Hi, a 12V DC power supply would be too low a voltage. You ideally need 20V DC or above (or 12V AC or above). Don't exceed 25V DC or 16V AC, otherwise you will damage the CDU. Make sure you use adequate wiring. For more information on wiring sizes, see: www.blocksignalling.co.uk/index.php/capacitor-discharge-unit-cdu1c-cdu2c-cdu4c
