LED and audible alarm troubleshooting

The DirectFlow UPS is designed for durable, automatic operation and also to alert you whenever potential
operating problems might occur. The alarms do not necessarily mean that the output power is affected;
instead, they are often preventive alarms intended to alert you of a possible condition. An operating problem
might trigger the following activity:
•
An audible alarm announced by a buzzer in the power unit
•
LEDs illuminating, flashing, or not illuminating on the control panel
•
Alarm descriptions that appear on the LCD screen
•
Alarm entries or related event entries that appear on the Alarms screen or the Event Log screen of the
Management Module web interface
The following table describes typical alarms and conditions that are accompanied by LED behavior on the
power unit front panel.
