Can I change the Quattro AC OUT 2 Time delay?

Is it possible to change the delay which it takes for AC out 2 to go live?


I have contactors which are being driven by AC OUT 2, but when the grid or generator input is live (after a mains failure or return) it takes around 2 and a half minutes for AC2 to go live, and hence close the contactors... Is there any way to change this to 30 seconds for instance?

Yes,
By programming Assistants, they will overrule the standard setting.

But so you also have to programm an Assistant to turn it off etc

May be changing AC1IN and AC2IN is more suitable for you application.
I changed the Gen to AC2IN, to be able to ignore gen start when AC1IN (shore) is on.


In the manual it was suggested the otherway around.


AC1IN might be default to connect to AC2OUT......

Hi @Harold


Our setup is exactly how you have done it as well, Grid is on ACin 1 and Gen is on ACin2.

As I see it, trying to create an assistant using basic logic isnt possible withought an AND function, as victron only allows for OR's.


For instance:

if AC in 1 is not available for 1s turn off ACout2

if AC in 2 is available for 30s turn on ACout2

the problem comes in turning off ACout 2 when both ACin1 and 2 are available. because now you have conflicting statements. Acout 2 won't turn off if it is being kept on by ACin2 being available...

Not sure I am making any sense, but I did get this feedback from a previous post. Haven't had an update from VIctron yet.

Clear!

for me ;-)

Hi @Harold,


I seemed to have never replied to your answer, thank you for the comment, although this is how you can change it, it seems there is no way to make it operate exactly like it is supposed to. for instance:

When Mains falls away - ACout2 turns off (this can be done)

When gen starts - ACout2 turns on after X number of seconds (this can be done)

When Mains mains returns and gen is still on - ACout2 turns off (this can not be done)

When ACout 1 is powered by Mains - ACout2 turns on after X number of seconds (this can be done)

I am trying to figure it out now again, looking for more complicated solutions which might solve it, any suggestions would be welcomed.
