Reactor motor fault interlock
Thread Content
Guys, I need help. Please help!； The PID diagram indicates a motor current fault and an interlock with the hot and cold medium valves of the reactor. I’m wondering how to determine this motor current fault? Is a value below 0.3 times the rated current considered a fault? Is a value higher than 1.3 times the rated current considered a fault? Is the loss of the current signal considered a fault?
You’re referring to the fault signals from the motor, those transmitted from the electrical side, such as start/stop, remote/local signals!
The values for the current signal and valve interlock should be specified by the process; for cases where the criteria for overload are not clearly defined, specific values must be determined through trial and error. The motor current should generally not exceed its rated value. Determining light load can be done through no-load operation; it depends on your process requirements
The inverter has fault alarm points in digital form
