Hi:
For the first time we setting up a T300 system.
We use T300 at for a standby generators system.
Self-return mode will be our choice for. But we can't find where is this mode can be set.
We try to use HU250's output to start generator. Is this passible to use on a T300?
And we got a setting for this system But can't find all need to set value.
Where can i find a typical ATS setting using on a T300 for reference?
Thanks if anyone can help on first time setting.

Hi Ray
Yes Easergy T300 provides Automatic source transfer functionality, including selection of return mode
Here is the corresponding setting as described in User's manual
"Allow back to normal source" p 144 and detailed on page 148. Select "YES" in your case
"Controls the behaviour after a transfer to the backup source and
voltage returns on the normal source.
"No" means that the ATS waits for voltage absence on the backup
source.
"Yes" means that the system transfers back to the normal source.
"Use a variable" means that back to normal is enabled depending on the
value of a variable (coordinate AATS_BLK_SELF_RE
T)"
Note that native automatism is meant to manage 2 normal/backup sources.
It may be easily adapted to manage a normal source and a generator
For this follow attached application note

Hi @jean-luc_batard :
Thanks for the document. We'll check for detail.
One more question is does the ATS setting in T300 by default?
Or i need to add in like this video by Easergy Builder?
https://www.youtube.com/watch?v=lPYYkBbsWVU
I did see some set up need to be added by Easergy Builder in document.
Cause we don't have any experience on Easergy Builder.
We may have to check how to use Easergy Builder first or
We can set by Web on T300 if the ATS setting is in T300 by default.
Many thanks
