What do UA, HS, XL, DO in the image mean? What does it represent?
Reply #22019-04-17
HS represents the start/stop button of the LCP; XL and UA likely denote common alarms, including fault alarms, shutdown alarms, and start/stop status signals. DO should represent the interlocked output associated with the LCP

UA stands for fault alarm; what does TIMER next to it mean?
