Staircase Timer Switch on LEDs

[Jon Bridges]

Made a bit of a boo boo and have replaced 10 standard light fittings in a stairwell for LED's without thinking about whether or not the staircase timer would work with it. It didnt!

Can anyone recommend a staircase timer switch that will work with 320w of LEDs? Ive searched on line and come up with an Eltako TLZ12G which can handle 400watts but then puts in a disclaimer that this needs to be dimmable LED.
Any suggestions greatly appreciated.

What sort of timer is in place at the moment.

I fitted one myself and has selectable loads, worked well for me!

Are you referring to push to make switches that operate a din rail delay staircase timer or vacuum plunger switches?

 

[Jon Bridges]

Sorry, its a din rail delay staircase timer with press switches.

It has one of these at the moment 1 to 7 Minute Staircase Time Switch - https://www.tlc-direct.co.uk/Products/CMTSSL1.html

What's not working? Are they not turning on or off? Are they flashing? Is the startup current too much?

 

[Toneyz]

Maybe use the time switch to switch a contactor .

Am I missing something but I don't understand why it no longer functions.

Me too

It has something to do with the drivers used in LED lighting.

I assume the issue is because the load is to low.
The lights will come on if you press the override switch on the timer. If I switch it back to the timer function they work once and then just wont be pressed back on again.
It seems as though the timer switch needs a certain load to reset itself.

Did they work ok before the lights were changed to LED?

Yes. The issue has only arisen since I changed the lights over.

It is essentially an electro mechanical switch, I do not understand why it has stopped because you changed the fittings.

Ive just found the ELPA8 timer switch data sheet and it says a max of 300w LED load. I've got 320 watts. I cant believe its that sensitive that it would not work due to an additional 20 watts.
