Figure 62.  SAFETY PARAMETER CONFIRMATION

Press the Yes button to confirm each safety parameter block. If the No button is selected, the safety parameter block remains unconfirmed and the Configuration menu page is displayed. The control remains in an unconfigured state in this case.

After all safety parameter blocks have been confirmed, the installer is asked to press and hold the Reset button on the Burner Control to complete the safety verification session (see Figure 63).

Figure 63.  SAFETY PARAMETER RESET

When the Reset button is pressed and held for 3 seconds the confirmed safety parameters are saved in the control. The above Reset dialog box automatically closes when this step is completed.

If this step is not performed, the control remains in a safety lockout state until the installer resolves the unverified safety parameters.

FAULT/ALARM HANDLING

Each Burner 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 (for S7999B), the History button turns red. If the S7999B is displaying the system status icons, the control in alarm will turn red.

The lockout history can be displayed by pressing on the History button. The state information about each lockout is displayed along with the date/time that the lockout occurred (refer to Table 21). Current date/time stamp is a display setup feature.

Note: In the event of a power interruption, the date/time must be reset. The OI Display does NOT have a backup means.
