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.

Note: The system time can be set in the OI display to ensure that correct timestamps are given to the controls’ lockouts and alerts. Power interruptions will require the time to be reset as the display DOES NOT have a time backup means.

The Clear Lockout button allows the user to acknowledge and clear (reset) the lockout when in lockout state, much the same as pressing the reset button on the front of the Burner Control.

The user can toggle between displaying the controls’ lockout history and alert log by pressing the Alerts or Lockouts button on the bottom of the pages.

Figure 64.  EXAMPLE OF HYDRONIC HISTORY

Two types of historical data can be displayed on the history page: lockout history and alert log.

The entire 15 fault code 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.

Figure 65.  EXAMPLE OF LOCKOUT HISTORY

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 Burner Control does not maintain date or time of day information. The date and time stamp is assigned by the OI display. When the OI display first obtains the lockout and alert history from the control (during the display data synchronization), no timestamps are assigned since the times that the lockouts occurred are unknown. All new lockouts that occur after the synchronization are assigned timestamps.

Figure 66.  EXAMPLE OF ALERT SHOWN

To see additional detail about a lockout or alert, touching on the lockout or alert in the list expands the view of that lockout or alert, as shown in Figure 65 and Figure 66.
