I am in the process of building a 150 hp hydraulic power unit to operate a hay press. This is a new installation into my business and I would like to set it up nice, but economically. I have many different issues to work through, but I have a few I really need advice on. The motor I am using is an ABB 150 hp wye start, delta run motor. I have the 3 contactors and do not want to spend the money for a 150hp soft start. It will be tied to 2 variable displacement, electronic pressure comp pumps, so I can start the motor under no load. My questions are as follows:
Is it a good idea to control the wye/delta start-up sequence with a plc?
Should I use the plc to control overload monitoring on my motor with a CT to analog?
Should I CT to analog all three phases or just 1?
I have a spare plc and a touchscreen and the need to monitor many different things. I just thought it would be nice to have a command center monitoring all of the electrical system and the start up and shut down.
Cooling Circuit
Cooling Fan
Pump Comps
Oil Temp
Oil Level
Pressures
Motor Temp
Any advice and product information would be appreciated.
