5.SYSTEM STATUS. When the SYSTEM STATUS box on the Mimic Display Screen (Figure 14) shows a flashing FAULTS AND ALARMS message, highlight it and press SELECT. This displays information about faults and alarms. Fault messages are displayed in reverse video (highlighted - light on dark) while alarm messages are displayed in regular video (dark on light). Alarm messages activate the audible alarm until the ALARM SILENCE button is pressed. To clear a latching alarm, you must also press the ALARM RESET button after the alarm condition is corrected.

Faults and Alarms

The Npower is designed to alert the Operator to system conditions that warrant careful monitoring and/or corrective action. A fault is an undesirable system condition that can cause further damage to the system or potentially drop the load if not acted upon. An alarm indicates an abnormal system con- dition significant enough to warrant being annunciated and logged. During normal operation no alarm messages should be present.
