Responding to System Events
12.1
General
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 System Event menu on the LCD screen to look at the Active
System Events screen. This screen shows any currently active alarms, notices,
or commands. (For more information on using the Events screen, refer to
paragraph 9.3.2 “System Events Screens of Chapter 9.)
12.2
System Event Horns
The system event horn beeps according to the type of event it is signifying:
•
Horn 1
— The Horn cycles on for 1 second at a one second rate. It is normally
used for all Alarm conditions.
•
Horn 2
— The Horn sounds for 3 second every three seconds. It is normally
used for all Notice conditions.
•
Horn 3
— The Horn sounds for 5 second every five seconds. It is normally
used to prompt the User for action.
12.3
System Event Lights
The status indicators on the UPS Control Panel work in conjunction with the event
horn to let you know when the UPS system is operating in any mode other than
Normal. Only the Normal indicator is visible during normal UPS system 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, refer to paragraph 9.6 “Reading the Status
Indicators” of Chapter 9.)
