YSL, YSA, HS – what is this diagram meant to represent?
YSL pump shutdown status switch, YSA pump shutdown status alarm, HS manual switch
Alarm interlock system for high motor temperature, with 5 monitoring points; it provides corresponding alarms and displays relevant operational information, allowing for manual shutdown of the motor on-site!
Looking at the terms ‘English’, ‘operation’, ‘alarm’, ‘stop’ – it seems to be for indicating the status of the motor
YSL pump operation status indicator, YSA operation fault alarm, HS control room DCS stop button
The question has already been answered; I’m just curious why such an expensive motor requires so many temperature monitoring and alarm functions What a waste
This refers to the temperature indication, alarms, and status alerts for the motor; it is handled by the electrical team, and the settings are generally determined based on the requirements of the motor itself.
Motor operation signal, stop signal, start alarm, multiple temperature display alarms
