History Page
The History button serves not only as a button, but also
displays 833-3639 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. 17) that allows the user to select the type of history
to view. The user can also silence an audible alarm generated
by the 833-3639 during a lockout or alert 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.

Two types of historical data can be displayed on the history
page: lockout history and alert log.
The entire 15 fault history is displayed in a scrollable list with
the most recent fault displayed first followed by the next most
recent fault. Summary information is displayed for each fault
entry, including the burner cycle count, fault code, and fault
number with description. Detailed information for a specific
fault entry that also includes burner control sequence state,
burner run-time hours, annunciation status, etc., is viewed by
selecting (touching the History line) the lockout entry in the list
(see “Fault/Alarm Handling” on page 10 for details).

The date and time that each fault occurred is displayed in the
lockout history. The lockout timestamp displays in both the
lockout summary and detail information.
The 833-3639 has no system time; the timestamp is assigned
by the 833-3577 when it learns of the lockout from the 833-
3639. When the 833-3577 first extracts the lockout history
from the 833-3639 (during 833-3639 data synchronization), no
timestamps are assigned since the times that the lockouts
occurred are unknown. All new lockouts that occur after the
extraction are assigned timestamps.
NOTE: The system time can be set in the 833-3577 to
ensure that correct timestamps are given to the 833-
3639 lockouts. See “System Time” on page 50 for
additional information on setting the display clock.
The Clear Lockout button allows the user to acknowledge and
clear the lockout when in lockout state.
The user can toggle between displaying the 833-3639 lockout
history and alert log. The Alerts or Lockouts button on the
bottom of the pages toggles the history displayed to the type
indicated by the button.
Alert code Unique code defining which
fault occurred.
