ENGLISH 8. Troubleshooting The Eaton 9PX is designed for durable, automatic operation and also alerts you whenever potential operating problems may occur. Usually the alarms shown by the control panel do not mean that the output power is affected. Instead, they are preventive alarms intended to alert the user. • Events are silent status information that are recorded into the Event log. Example = "AC freq in range". • Alarms are recorded into the Event log and displayed on the LCD status screen with the logo blinking. Some alarms may be announced by a beep every 3 seconds.

Action The UPS is powering the equipment with battery power. Prepare your equipment for shutdown. This warning is approximate, and the actual time to shutdown may vary significantly. Depending on the UPS load and number of Extended Battery Modules (EBMs), the "Battery Low" warning may occur before the batteries reach 20% capacity. No battery LED is On. Beep continuous. Battery fault LED is On. Beep continuous. The UPS does not provide the expected backup time. Bypass mode LED is on. Power overload LED is On. Beep continuous. The batteries are disconnected. Verify that all batteries are properly connected. If the condition persists, contact your service representative. The battery test is failed due to bad or disconnected batteries, or the battery minimum voltage is reached in ABM cycling mode. Verify that all batteries are properly connected. Start a new battery test : if the condition persists, contact your service representative. The batteries need charging or service. An overload or a fault has occurred, or a command has been received and the UPS is in Bypass mode Apply utility power for 48 hours to charge the batteries. If the condition persists, contact your service representative. Equipment is powered but not protected by the UPS. Check for one of the following alarms: overtemperature, overload or UPS failure. Power requirements exceed the UPS capacity (greater than 100% of nominal; see in table 6 on page 43 for specific output overload ranges). Remove some of the equipment from the UPS. The UPS continues to operate, but may switch to Bypass mode or shut down if the load increases. The alarm resets when the condition becomes inactive. Page 39
