When the UPS system is running in Online mode, it continually monitors itself and the incoming utility power.
In Battery or Bypass modes, the UPS may issue alarms to display exactly what event caused the change from
Online mode. System events on the UPS can be indicated by horns, lights, messages, or all three. See

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 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
•
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 Active Events Log and may be added to the History Log.
The messages are divided into four categories: alarms, notices, status, and commands. The user log
window (
1
) allows the operator to enter any number up to the number shown to the right of the box. Each
window shows five events. The operator can also use the UP/DOWN arrows above and below the blue
field (
2
) showing the number of events in the log. See
