Danlers CEFL Pir doesn’t trigger

[Mootaw]

Hi All,

I’ve recently replaced my PIR in my shower room it’s been replaced and wired in exactly the same as before when turning power back on at fuse board then walking into Shower room light triggers the once then goes off but then won’t trigger again am I looking at a faulty unit or am I missing something. Thanks for any advice.

Faulty unit
Wired wrong
Settings wrong
Incompatible unit

are 4 of the possibilities. Hard to see from here

What adjustments can you do ?
what model is it ?

Have you reversed the Pl and Sl ?

Thanks for your help. Black flex is the PIR

No cpc going to the PIR

Black cable is the PIR it’s a sealed in so already wired up into PIR by manufacturer. White cable goes to the low voltage halogen lights that PIR should turn on.

I'd check the lux level, possibly set to only cone in when much darker.

He’s already adjusted lux
Sounds like a duff one. I’ve had a couple recently. Replace with another one? Do you have any others in the house you can experiment with

Go back to basics and bypass the pir to check the lights still work

To expand on Murdoch's back to basics comment above.....

Possibly you may have replaced something that was not faulty?
and now still have a different fault causing your problem?

Test the new PIR on a worktop connected to a plug & lamp holder to see if actually does work?
(some lever Wago connectors a great help for quick temporary testing)
