Chapter 10 Responding to System Events
When the UPS system is running in Normal mode, it continually monitors itself and the
incoming utility power. In Battery or Bypass modes, the UPS may issue alarms to let you
know exactly what event caused the change from N ormal mode. System events can be
indicated by horns, lights on the UPS, or both.
Select Active fromtheEventsmenuontheLCDscreentolookattheActiveSystemEvents
screen. This screen shows any currently active alarms, notices, or commands.
10.1 System Event Horns
The system event horn beeps according to the type of event it is signifying:
Ī When the UPS detects an alarm that requires your attention, the horn beeps at
½-second intervals.
Ī When a notice occurs, the horn beeps at 2-second intervals.
10.2 System Event Lights
The status indicators on the UPS Monitor Panel work in conjunction with the event horn to
let you know when the UPS is operating in any mode other than Normal. Only the Normal
indicator is visible during normal UPS operation. The others light to indicate alarms or
events. When an alarm occurs, you should first check these indicators to see what type of
event has taken place. (For descriptions of the status indicators, see “Reading the Status
Indicators” on page 5-4.)
10.3 System Event Messages
When a system event occurs, a message is added to the Event History Log. A message may
also appear on the Monitor Panel of the UPS. The Event History Log contains all system
event messages, whether or not they were displayed on the Monitor Panel.
