Alarms Screen - ABB PGC2000 Operation And Service Manual

When an alarm signal appears on the Background Screen, press the F4 (Alarms) soft key to display
the ALARMS screen with the alarm message (see Figure 6-19).
When you finish with the alarm messages, press the F1 (Exit) soft key to return to the Background
screen without deleting the alarms, or press the F2 (Clear Alarms and Exit) soft key to clear the
alarms and return to the Background screen.
Alarm messages are of two primary types: main alarms and subordinate alarms. Main alarms identify
a major alarm category. These alarms appear on the alarm screen at the left margin (e.g., "Post
Analysis Error:" in Figure 6-20). The main alarms are:
Hardware Alarms
Sensors Active:
Sensors Held:
Startup Hardware Problem
Power Failed
Flame Out
Subordinate alarms appear below the main alarms, indented and preceded by an asterisk (*) to show
their subordinate status (e.g., "*Valve Manually Switched" in Figure 6-19).
If a main alarm has subordinate alarms, the main alarm title will include a colon (:). The following
subsections list the main alarms that have subordinate alarms, together with their associated
subordinate alarms.
