Enable ACOut2 while inverting

I am trying to use assistants to turn on/off ACOut2 on my Quattro 2x120. Building and uploading all goes as expected except when I use AC Out 2 relay, leg 2 stays on all the time; leg 1 operates as expected based on the AOC values set.

This relay functions correctly with shore power applied and removed so it is not a hardware issue, and opens when all AC out 2 assistants are deleted.

I’ve also changed the assistant to use other relays and it behaves as expected.

I only have this issue using an assistant for AC out 2 relay

Bump?

Can you post your programming?

Try put the on one at the top.

Same behavior, ACOut 2, L1 toggles on and off, L2 stays on.

7

Very weird.
Are there any other conditions set for ac2 out or just those?

8

No, those are the only 2 assistants I have.

9

I really feel like the assistants dont have a function inside them for L2, since other than the 2x120s there was no reason to have a L2 function…

10

Do you have AC IN connected?
How does it behave without AC IN?

11

On a single phase power source (we currently only have 15A shore power) there is no difference. Without the assistants, on 50A power, it behaves as expected; I have not had 50A shore power since trying to get the assistants going, since I didn’t need them when I had full power…

Earlier, I had switched the inverter to Invert only, and it was the same behavior, L1 switching, L2 staying on.

Downloading, and sending my assistant files to my distributor resulted in the MP they have for testing behaving 100% as expected.

I have 2 Quattros and both have this behavior independently (I have not programmed them for paralleling yet).

Is there something external to the Quattro that could be causing this phenomenon?

Again, without assistants, the unit functions normal and as expected.

13

I guess I am the only person here using a 2x120 that needs to control AC Out 2…

Yeah. Its not one i have used ever and am not likely to.
