I'm starting on a project that will soon involve controlling two large water pumps (4160 VAC, not sure the HP).
I'm curious: what generic "best practices" have you learned in regard to controlling large motors/pumps using PLCs? Any advice is appreciated - doesn't need to be application-specific.
For example, I know it's a good idea to implement timers to prevent fast state changes (i.e. wait X seconds before stopping or starting after the Call To Run changes state).
Also, alternate between pumps to distribute wear.
What tips, tricks, do's and don'ts have you learned along your way? Anything is appreciated which would help create a better/safer/more robust control algorithm.
