K8039

I just built a K8039 DMX Controlled Power Dimmer,
When i do the stand alone test it does some strange things.
When i first plug it in, it dims in nicely then just turns off, doesn’t fade. Then after that it does really short cycles, and still only fades in then turns off - not fading out.
Is this right or has something gone wrong,
I haven’t had a chance to test it on DMX yet.
Can anyone offer any advice???
Thanks

What load did you connect to the dimmer?

Originally just a 240v 50w GU10 halegon downlight globe
Then I thought I might not have enough wattage so I plugged
In a 1000w halogen tripod work light, which I
Know is right at the limit,
Both did the same thing
