Fault/Alarm Handling

Each Falcon control reports to the OI display when a safety
lockout or an Alert occurs.
Safety lockouts are indicated on each configuration page as
an alarm bell symbol. At the status page, the History button
turns red (see Fig. 16). If the 833-5105 is displaying the system
status icons, the control in alarm will turn red (see Fig. 17).

History Button

The History button on the Home page serves not only as a
button, but also displays Falcon Control lockouts, holds, and
alerts as they occur. The History button can be selected at any
time, regardless of which type of information is displayed, to
view history information. Pressing the History button displays
a dialog box (see Fig. 18) that allows the user to select the
type of history to view. The user can also silence an audible
alarm generated by the control during a lockout or alert by
alarm condition.
This History dialog box provides an exploded view of the
status information displayed in the History button (the font is
larger). One of the four buttons (OK, Lockouts, Alerts, or
Silence) can be selected. If none of these buttons are
selected the dialog box closes after 30 seconds.
