Greetings,
We (in the steel industry) have many pumps / motors (large and small). Generally we use soft-starts, cross-line starters (E3+) or even Flex drives. There may be several motors in a pool to start where we need only say 2 of 3 to be running at any one time When it's time to start them, we may need to stagger start them, if one fails, the spare may need to start. My question to the group is... Are there any philosophies out there (and hopefully pseudo or actual code) as to how to start a subset of motors/pumps within a pool of motors and maintain the configuration running ?
I appreciate any and all comments.
David
