4.5 ALARMS SCREEN
If we move from the main screen to the alarms screen, by pressing F1, as shown on the main screen graphic, the
relay will show a new screen, as the one below:
This screen shows a list of alarms that have been generated in the substation. The maximum number of alarms that
can be displayed is 12. Alarms are displayed as follows:
Alarm label, that is, associated text defined in GE-INTRO software
Time and date when the alarm was generated
When an alarm is produced, the screen shows the previous information with a dark shadow and blinking. The blink
and the shadow indicate that the alarm has not been acknowledged. In order to “acknowledge” the alarm, we must
press F2, as indicated in the help text shown at the bottom of the screen. Once the alarm has been acknowledged, it
stops blinking and the shadow disappears, but the alarm text remains on the screen until the reason that produced it
disappears.
At the bottom of the screen we can see the text “ACTIVE ALARM, NOT ACKNOWLEDGED”, “ACTIVE ALARM”, etc.
showing the status for each alarm.
The representation for the different possible statuses of an alarm are as follows:
Active alarm, not acknowledged:
Blinking, with a dark shadow, and marked with an asterisk
Active alarm, acknowledged:
Without blinking, marked with an asterisk.
Inactive alarm, not acknowledged:
Without blinking, with a dark shadow, without asterisk.
Inactive alarm, acknowledged:
Disappears from the screen.
