Dear Community.
I have a Problem or a question:
Did I somehow disabled the lights on my Multiplus II 5000?
Everything seems to work just fine, and once there were the lights for mains on/bulk//absorbtion..
But somehow during the configuration phase the lights went dark.
Everything works fine.
Its just that strange humming noise when its inverting ?!
Is it normal?
What can i do?
Sincerely
