Alarm Messages

The alarm message area displays the alarm conditions that are present within the UPS system. Alarm messages are displayed in flashing reverse video. During normal operation no alarm messages should be present. Up to four messages are displayed. To see if any additional alarm conditions are present in the UPS system, display the Present Status screen on the control panel.

Table 1 is a complete list of all alarm messages and corrective actions, if any. The first column lists the alarm message, with related alarms grouped together.

The third column indicates which special functions (if any) are initiated by the alarm.

D - the alarm initiates an auto-dialcall through a user-provided modem to a remote terminal. E - message displayed only on Status Report screens including Event History.

F - the alarm freezes the History Status Report memory buffer in the cabinet where the alarm is displayed. Pressing the Alarm Reset pad for 15 seconds will unfreeze the memory buffer.

L - the alarm latches the displayed alarm message. Some alarm conditions are temporary (transient) and may not last long enough to be noticed. Latching the display (keeping it on) lets you know that an alarm con- dition has occurred. A latching display alarm remains on the display screen until the alarm condition is removed and the Alarm Reset pad is pressed.

R - the alarm is displayed on an (optional) Remote Monitor Panel. This information is also available for customer use through a set of contacts on a separate terminal board.

S - the alarm initiates a summary alarm at the Remote Monitor Panel and at the SCC.

The fourth column provides an explanation of the alarm condition, the critical bus status, and the corrective actions, if any, to remedy the alarm.
