8.6 Reading the Status Indicators
The five symbols on the left side of the control panel are status indicators. They are
backlit by 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 symbol is lit when the UPS is operating in
Normal mode. The power processing unit (PPU) is
supplying power to the critical load.
BATTERY
This yellow symbol is lit when the UPS is operating in
Battery mode. Because Battery mode is a normal
condition of the UPS, the Normal indicator also remains lit.
BYPASS
This yellow symbol is lit when the UPS is operating in
Bypass mode. The critical load is supported by the
bypass source. The Normal indicator is not lit when the
system is in Bypass mode.
NOTICE
This yellow symbol is lit when the system needs attention.
The LCD screen shows all active notices. Some notices
may be accompanied by an audible horn. To silence the
horn, press the Alarm Off pushbutton switch. The Notice
indicator may be lit along with other indicators.
ALARM
This red symbol is lit when a situation requires immediate
attention. The LCD screen shows the highest priority active
alarms. All alarms are accompanied by an audible horn.
To silence the horn, press the Alarm Off pushbutton
switch. The Alarm indicator may be lit along with other
indicators.
For more information about audible horns, refer to the “System Event Horns”
section of Chapter 11.
