Chapter 11 | Responding to System Events |
When the UPS system is operating 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 Normal mode. System events on the UPS can be indicated by horns, indicators, messages, or all three.
Select Active from the Events menu on the LCD screen to display the Active System
Events screen. This screen shows any currently active alarms, notices, or commands.
11.1System Event Horns
The system event horn beeps according to the type of event it is signifying:
SWhen the UPS detects an alarm that requires your attention, the horn beeps at half‐second intervals.
SWhen a notice occurs, the horn beeps at two‐second intervals.
11.2System Event Indicators
The status indicators on the UPS control panel work in conjunction with the horn to let you know when the UPS system is operating in any mode other than Normal mode. Only the Normal indicator is illuminated during normal UPS system operation. The others illuminate to indicate alarms or events. When an alarm occurs, first check these indicators to see what type of event has taken place. For descriptions of the status indicators, see paragraph 8.4 on page
11.3System Event Messages
When a system event occurs, a message is added to the Event History Log. A message may also appear on the UPS control panel. The Event History Log contains all system event messages, whether or not they were displayed on the control panel.
