Please would someone help me with what I assume is a setting issue on the Profilux.

It is a Profilux 3 with Firmware 5.05f

I am trying to dim an AquaMedic pendant with 8 x T5s. The ballasts are dali dimmable ballasts, installed by the supplier. They were run in for 100 hours before attempting dimming.

On the Profilux, I have setup an illumination programme as follows:
Illumination 1: 08h00 - 10h00 0% / 100%
Illumination 2: 08h30 - 10h30 0% / 100%
Illumination 3: 09h00 - 11h00 0% / 100%
Illumination 4: 09h30 - 11h30 0% / 100%

If I manually check the dimming, it works perfectly. The programmed dimming to black at night also works perfectly.

The issue I am having is when they first switch on. The first two T5s (controlled by "Illumination 1") switch on at 08h00 (see above). At 08h00, these two T5s switch on at 100% and then immediately dim to 1%. The same thing applies with Illumination 2, 3 & 4. So at 08h00, there is a bright flash, as well as at 08h30, then 09h00 and finaly at 09h30, as each Illumination programme starts.

How do I sort this out? Obviously as it is, there is no point having dimmable ballasts!

Thanks for the help
