Or in case just fault situation is present:
Fig. 3.5.1 c) Active events screen with fault only
In case of a new event, the screen will automatically switch to the Active Events list
and the buzzer will sound.
Until the event is acknowledged, the user cannot go back to the main screen. In the
upper figures 3.5.1.a, b and c the shown events are not yet acknowledged.
When acknowledged there is a “X” under the column “A”, for the related event.
In this screen there are three available options:
1 ACK
2 RESET
3 PRINT
ACK
By pressing 1 ACK with the cursor on the active event, this will get acknowledged.
There are two situations:
1. the user is already logged in.
In this case by pressing 1 ACK the screen image will simply refresh and an “X”
mark will appear on the “A” column (the “Acknowledged” column)
2. the user is not yet logged in.
In this case the LOGIN dialogue window pops up and the user should key in the
password. After which the “X” mark will be shown under the “A” column of the
related active event.
Practically this is the only situation when the login of an “Operator” level user is
required so that a trace is being kept about the person who acknowledged the
active event.
