Flashing Connection LED on PAB Powerbar

Hi,

I had another reefer come over and he noticed that all my PAB powerbars where flashing amber LED on the connection and said it shouldnt be doing that they should be solid.

All the sockets are working fine, i can control them in ProfiluxControl without any problems....

Should they be flashing???

Thanks

the connection LED (yellow) flashes when there is communication - the green LED should stay on permanently
