7.2.2System 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 Normal mode. System events on the UPS can be indicated by horns, lights, messages, or all three.

Select EVENTS from the menu bar on the main menu screen to look at the active events screen. This screen shows any currently active alarms, notices, or commands. For more information on using the events screen, see paragraph 7.2.6 on page 7−6.

SSystem 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.

SSystem Event Indicators – The status indicators on the UPS control panel work with the event horn to let the operator know when the is operating in any mode other than normal. Only the ON indicator is visible 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.

SSystem 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 Active Events Log and may be added to the History Log. The messages are divided into four categories: alarms, notices, status, and commands.
