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 Normal mode. System events on the UPS can be indicated by horns, lights, messages, or all three.
Select the EVENTS symbol from the menu bar on the main menu screen to display the active events screen.
This screen shows any currently active alarms, notices, or commands. This screen shows any currently active
alarms, notices, or commands. For more information on using the events screen, see paragraph
7.2.6 Display Menu Operation.
• System Event Horns – The system event horn beeps to alert an operator that an event needing attention
is taking place. The horn cycles at a half-second rate.
• System Event Indicators – The status indicators on the UPS control panel work with the event horn to let
the operator know when the UPS is operating in any mode other than normal. Only the Normal
mode indicator is illuminated during normal UPS system operation. The other indicators 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 7.2.1 Status Indicators.
• System Event Messages – When a system event occurs, a message appears on the LCD in the UPS
status area. This message is also written to the Events Log and may be added to the History Log. The
messages are divided into four categories: alarms, notices, status, and commands.
