Using the Control Panel

9.5Reading the Status Indicators

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 attention. The

 

LCD shows all active notices. Some notices may be

 

accompanied by an audible horn. To silence the horn, press

 

any control panel pushbutton 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.

Bypass

This yellow indicator is illuminated when the UPS is 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 requires

 

immediate attention. The LCD shows the highest priority

 

active alarms. All alarms are accompanied by an audible

 

horn. To silence the horn, press any control panel

 

pushbutton once. The Alarm indicator may be illuminated

 

along with other indicators. The indicator flashes until

 

acknowledged by pressing any control panel pushbutton

 

once.
