EVG-AP not dimming

Hi,

I have, for 6 months, successfully used the EVG-AP-2f-HIC on my Profilux 3.1N (6.11). It is hooked up to a Meanwell ELN-60-48D powering 13 or 15 (tried both amounts) Cree LEDs.

Now it is not dimming. It either lights to approximately 50% or to 0%.

No settings appear to have changed.

I have tried using both L1-2 and L2-3.

If you can help me brainstorming potential causes I would be very appreciative.

Thanks in advance,

Andrew
