Hey @Prem,

I tried your suggestion but have been stuck on a E1 error. I am fairly sure that the photocells are aligned and they have just been wired too so think there should be no cuts - could it be that they are faulty ? The manual mentions LED's but can't see any on either device so are scratching my head - any other ideas ?

Many thanks again.
