8.6Reading 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
BATTERY
BYPASS
NOTICE
ALARM
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.
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.
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.
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.
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.
