Micro-PWC OPERATOR’S MANUAL
78 Process Alarms
8.3 Process Alarms in the Mini-Alarm Window
Process alarms are displayed in the top two lines of the Mini-Alarm Window. If more unacknowledged pro-
cess alarms exist than can be displayed in the Mini-Alarm Window, then the message +ALARMS appears
in the title bar of the Mini-Alarm Window.
8.3.1 Process Alarm Priorities
Sixteen levels (from 1 to 16, with Level 1 being the highest) are available for use in prioritizing alarms.
The priority determines the importance of an alarm and the position in which it is displayed in the Mini-
Alarm Window. The priority also determines the color in which the alarm is displayed, and the type of audi-
ble alarm which accompanies it.
8.3.2 Audible Alarm Format
Audible Alarms are available in two formats on the Micro-PWC:
• Steady beep
• Rapid beep
The rapid beep is used for alarms with a high priority, while the steady beep is used for lower priority
alarms. The priority level which marks the division between the high and lower priority audible alarm for-
mats can be configured by the user, as described in the Micro-PWC Configuration Guide. For details on
the configuration of this item on your system, consult your system administrator.
8.3.3 Acknowledging Alarms in the Mini-Alarm Window
At the far left of each process alarm line in the Mini-Alarm Window is an Alarm Acknowledge button. An A
displayed on the face of the button as a request for acknowledgment, indicating the alarm is unacknowl-
edged. If the face of the button does not contain an A, the alarm has been acknowledged. To acknowledge
a process alarm, click on the Alarm Acknowledge button.
Alternatively, you can use the
A LT -F9 key combination. Note that only the first process alarm can be
acknowledged in this manner.
✎ NOTES
Data contained in the Mini-Alarm Window is automatically filtered
by the filtering mask configured for the user currently logged in on
the Micro-PWC, and by any additional filtering performed by the
user (see
Section 8.3.4, Filtering Alarms in the Mini-Alarm Window ).
This means that not all users will necessarily receive the same set
of alarms and messages. When there are no unacknowledged
process alarms, system events, or messages in the Mini-Alarm
Window on a particular Micro-PWC console, the audible alarm will
be automatically turned off for that user until the next
unacknowledged alarm or message appears in the Mini-Alarm
Window.
Note that there can still be unacknowledged alarms on the
system that are not visible on the user's screen, due to the
filtering configuration.
A Silence button (with a horn icon on the button face) appears on
the Mini-Alarm Window title bar when audible alarms exist. This
button corresponds to
A LT -F11 on the keyboard, and can be used to
silence (but not acknowledge) alarms for the node on which it
appears.
