Quattro Programmable relay - AC input

Hi, What are the AC input conditions for the relay to shift? Via the programmable relay we would like to know if the load is on inverter or on mains.

It seems like the relay is switching all ready at approx 50VAC input voltage!? Result: The relay indicates that AC input is available, but of course the load is still on inverter at this low input voltage.

@Peter Rysholt Christiansen

It seems you've already found out...

How can you have 50VAC on the input?

Hi, Daniël,

NO, I did not find out.

I am still looking for a relay function to indicate if the load is on inverter or on mains.

How is it that the Quattro says "AC input" at all ready 50VAC input voltage? The 50VAC input voltage is the voltage we reached during lab test when the programmable relay switched.
