hi anil, An annunciator system comprises sensors connected to a computer or controller. When the parameter being monitored moves outside of the acceptable range an audible alarm sounds and a panel flashes to draw the operator's attention to the alarm. The operator then follows approved procedures to correct the abnormal condition and restore the plant to a normal status. The purpose of the annunciator is to provide the plant operator with early warning of a problem, which allows time to take action before a situation degrades to the point where the process can no longer be controlled. Avoiding unnecessary challenges and trips is good for the plant's bottom line, as well as for safety The annunciator is most often used for critical alarm display and the trapping of alarm conditions, since many alarms are transient in nature and are difficult to diagnose after the fact. Critical alarms displayed on annunciators are consistent and easy for operators to recognise and deal with. They are also arranged in prominent locations within a control room so that they provide the best possible warning to the plant operators and offer the best performance in terms of plant safety. I Dint see this system in PCS7. We have an Alarm Management System in PCS7 in which you can suppress nuisance alarms and also can hide the nuisance alarms. I attached a 2 page document which gives you a picture. Hope this helps. regards, AttachmentAlarm Hiding & Shelving.pdf (152 Downloads) |
