PowerLogic T300 - Is it possible to use T300-ATS for 3 MV sources?

[med]

Hello everyone,
I’m working on configuring a 3-source ATS using a Schneider PA T300, and I’m not sure which method is required.

Can this logic (source selection, priority, switching commands, interlocks) be done only with formulas inside Easergy Builder, or do I need to use ISaGRAF / FBD to build the control sequence?

If someone has already managed a 3-source ATS on a T300, which approach do you recommend, and why?

Thanks for your help!

@Mathieu_Lansoy , could you please support @med with his question?, thanks.

Hello,

This kind of solution can be better developped with an ISaGRAF program. This is more efficient to manage sequences, loops and timers than the formulas, and adapted to "PLC programming" thinking (if you know FBD language for example).

you can find examples of programs done for a 2-source ATS on the T300_sharepoint and rework them.

regards,

  Mathieu.

Hello Med,

T300 ATS algorithms that are provided free of charge (whether in T300 firmware or as ISAGRAF ready-made programs) are for 2 MV sources:

1. Auto-Change Over (between 2 MV lines),
2. GENerator (between a MV line and a GENSET)
3. Bus Tie Automatism (between 2 MV lines and with a coupling MV switch)

As Mathieu explained, you can develop your own ATS system (for example, with 3 MV sources). For that, you need to purchase an ISaGRAF 5.22 license from Schneider Electric to build your program.

Once your program is fully tested, you can inject it into as many T300 units as you want (the license is only required to create the program, not to use it).
