How to delay the anti islanding ZIEHL UFR1001E ON action for more than the default 60s after poweroff?

So I have this anti-islanding device, works great with all the functions and settings it provides, redundant relays, protections for frequency, undervoltage, overvoltage etc. but now I also need it to delay bridging after LOM for 15 minutes in order to be allowed to feed-in again.

I'm using the default program 2, I tried altering the various doF from the default 60 including from the U-0 but it seems it ignores them.

Thanks!

Maybe try to use programm 13 (or 1). I believe in programm 2 the values are fixed.

Thanks for this! Indeed I selected program 1 then suddenly undervoltage doF (U_) reacts to whatever time I select! Somehow on the default P2 it was ignored.

With my UFR1001E it works without problems. I have reduced the different doF (9 times in total) from 60s to 30s. I use programme 7 because I only have one phase.

Maybe you can simply add a time relay to the input (power supply) of the Ziehl.

Yes I thought of this but seems overkill since the product is programmable.
