PIR won’t turn off - what am I doing wrong?

[mattman]

Just installed a new LED PIR light on the shed at the bottom of the garden. All works fine on the switch, but appears to refuse to turn off.
I used the same connections as the previous installed light (no PIR sensor) as shown in the photos below (cable to light is the black one) - does this look correct or have I wired it up wrong?

When I turn the power on, the light comes on and stays on.
I’ve twiddled the adjustors and doesn’t seem to make much difference

Will turn it on again and leave it for a while to see if it sorts itself out

Sorry guys, completely forgot about this. Light stayed on and then finally seemed to set itself. Been good ever since and not electrocuted!
