As previously mentioned, faults are shown in reverse video, and alarms in regular video. For a com- plete list of all the alarm messages and corrective actions for these faults, refer to Table 7 - Alarms, functions, and corrective actions.

The Emergency Off and Hardware Shutdown alarms will also freeze the History Status buffer with the Auto Transfer to Bypass alarm (if the load is on the UPS system when the alarm condition occurs).
The History Status buffer does not resume collecting new frames until the fault is cleared.
