Hi,
I'd like to know more (technically) how the Ziehl UFR1000E works.
How can it detect LOM if the system is exporting current?
And what about if a genset is running, how come it doesn't close the contactor/relay when the frequenzy and voltage is within limits?
The current doesn't flow through the device, so it has no idea in what direction the current is flowing.
Is the Ziehl unit dependent on functions of the quattro/multiplus of some sort?
What differs LOM type A from Type B (technically)?
Why can't one choose Type A when Grid code Other is chosen?

Do you know and can explains this?
If you really want to know...read the manual:

I'm no expert, but it measures things like grid impedance, frequency changes, etc.

It was these two questions i meant.
"What differs LOM type A from Type B (technically)?"
"Why can't one choose Type A when Grid code Other is chosen?"
