Hello, every body.
i need to operate a three water pump motors 4KW-3ph-380v on an one drive ACS550 4KW, i can do it by standard PFC , but the client ordered me to use also the Autochange mode.
my power circuit is to be like this

but i can`t manage the control circuit, on page 189 of user manual the picture show that i need a relay logic to control of this operation.

I have already a Zelio logic relay (SR2B201Fu) with 12 inputs (9 digital + 3 analog) and 8 digital outputs
my question is
who can i make the autochange mode with only(ABB ACS550)if it can work
OR with
(ABB ACS550 + Zelio SR2B201Fu)
thanks for your replies.
