The four symbols on the right side of the control panel are status indicators. They are
colored light emitting diode (LED) lamps, and they work in conjunction with the alarm
horn to let you know the operating status of the UPS.
Normal This green indicator is illuminated when the UPS is
operating in Normal mode. The power module is
supplying power to the critical load.
The indicator flashes when the system needs

once. The indicator may be flashing while other
indicators are illuminated. The indicator continues to
flash until acknowledged by pressing any control
panel pushbutton once.
Battery This yellow indicator is illuminated when the UPS is
operating in Battery mode. Because Battery mode is
a normal condition of the UPS, the Normal indicator
also remains illuminated.

operating in Bypass mode. The critical load is
supported by the bypass source. The Normal
indicator is not illuminated when the system is in
Bypass mode.
Alarm This red indicator is illuminated when a situation

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 let you know exactly what event caused the change
from Online 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 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 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 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 Active Events Log and may be added to the History Log.
The messages are divided into four categories: alarms, notices, status, and commands.
