Micro-PWC OPERATOR’S MANUAL

Process Alarms 77

8.0 Process Alarms

8.1 Introduction

A Process Alarm is generated when a process variable is in an abnormal condition. Process alarms are
displayed in the first two lines of the Mini-Alarm Window and are accompanied by audible alarms. A com-
plete list of Process Alarms is contained in the Alarm Review display. Like other messages generated on
the system, Process Alarms are stored in the Historical Database and can be viewed on a Micro-PWC, or
logged to a printer using the Event Historian (refer to

Section 9.0, Events

). Process Alarms can also be

logged to a printer as they occur.

8.2 Mini-Alarm Window Title Bar

The title bar in the Mini-Alarm Window identifies the window by the Micro-PWC name. The name of the
current host node is displayed to the right of the Micro-PWC address. The title bar also contains a string
which can be configured to provide further information, such as plant name and location. The login name
of the user currently logged in on the Micro-PWC appears on the title bar, followed by the More Alarms
(+ALARMS) indicator (if more alarms exist), a Silence button and the Filter button. The Silence button
contains a horn icon on the button face, and is visible only when audible alarms exist.

8.2.1 Alarm Indicator

The +ALARMS indicator is located on the Mini-Alarm Window title bar, immediately to the right of the login
name of the user currently logged in on the Micro-PWC. This indicator appears when more process alarms
exist than can be shown in the alarm display area (i.e., when there are more than two process alarms).
