Control on the motor in the flowchart
Thread Content
I would like to ask the teachers: what do YS, YL, and the start/stop points between the lines in the diagram mean? Thank you!
Please check the meaning of the diagram on the P&ID homepage； YI: Y indicates; YS: Y switch (start, stop)
Thank you for the reply. It’s the same as in hg20505. Could it be that the start/stop of the motor via the DCS and the motor’s current start/stop status are displayed on the DCS?
These are the labels for the control buttons on the motor; you can’t just draw a button on the PID diagram – you need to follow the rules regarding how PID diagrams should be drawn
Thank you again! I need to provide this motor to the client now. I’m worried that these two markings might be related to the motor’s specifications; if I ignore them, problems could arise. It seems that no additional configurations are needed for the motor after all
Is everyone gone? . . Please help. . .
YL: Status light YS: Switch for motor M
Both tables have square frames, indicating that they are tables or switches on the DCS, not at the site
YL is the operating display for removing DCS, while YS is the start and stop signal; the motor in question does not require any additional configurations. These signals come from the cabinets in the DCS to the electrical distribution room.
