4. Troubleshooting The UPS system control panel LEDs will illuminate in the sequences listed below to indicate operational problems. Note: If the "FAULT" LED illuminates, determine the specific fault condition by activating the error code LEDs. To activate the error code LEDs, press the "ON/TEST" button until the UPS system beeps, then release the button. The error code LEDs will illuminate for 5 seconds. Illuminated LEDs On: REPLACE BATT Error Code LEDs: Not Applicable Flashing: LINE Error Code LEDs: Not Applicable On: FAULT Error Code LEDs: 50% 100% On: FAULT Error Code LEDs: 25% 75% On: FAULT Error Code LEDs: 25% 75% 100% On: FAULT Error Code LEDs: 25% 50% On: FAULT Error Code LEDs: 25% 50% 100% On: FAULT Error Code LEDs: 25% 50% 75% On: FAULT Error Code LEDs: 25% 50% 75% 100% On: FAULT Error Code LEDs: BATT 75% 100% On: FAULT Error Code LEDs: BATT 25% On: FAULT Error Code LEDs: BATT 25% 100% On: FAULT Error Code LEDs: BATT 25% 75% On: FAULT Error Code LEDs: BATT 25% 50% On: FAULT Error Code LEDs: BATT 25% 50% 100% Condition and Solution Replace Battery: Allow the UPS system to charge for at least 12 hours and perform a UPS system self-test as described in Section 3.1: Front Panel Switches. If the LED remains on, contact Tripp Lite for service. Input Abnormal: Utility power voltage or frequency is too high or too low for the UPS system to operate in BYPASS mode. If an inverter failure occurs, the UPS system will not pass through utility power to the outlets and any connected equipment will turn off. Battery Weak: Allow the UPS system to charge for 12 hours. If the LED remains on, contact Tripp Lite for service. Inverter Over-Current: Reduce the load supported by the UPS system by unplugging some equipment. Restart the UPS system. If the problem persists, contact Tripp Lite for service. Internal Temperature Too High: Confirm that adequate space exists for air to circulate near the UPS system's vents. Confirm that the UPS system's fan is working properly. Confirm that the ambient temperature does not exceed recommended levels. Restart the UPS system. Inverter Overload: Reduce the load supported by the UPS system by unplugging some equipment. Charger Out of Order: Restart the UPS system. If the problem persists, contact Tripp Lite for service. Fan Out of Order: Restart the UPS system. If the problem persists, contact Tripp Lite for service. Bypass Phase Can't Lock: Restart the UPS system. If the problem persists, contact Tripp Lite for service. Wiring Fault: Check the utility line for wiring problems such as reversed line and neutral or a missing ground. The UPS system will detect some (but not all) wiring faults. Contact an electrician to verify the AC input wiring. Utility Voltage Low and Battery Disconnected at Initialization: Shut down the UPS system. Check the internal battery connections. Correct the AC input voltage. Restart the UPS system. If the problem persists, contact Tripp Lite for service. Utility Voltage Low and Battery Disconnected in On-Line Mode: Shut down the UPS system. Check the internal battery connections. Correct the AC input voltage. Restart the UPS system. If the problem persists, contact Tripp Lite for service. Input Over-Current: Reduce the load supported by the UPS system by unplugging some equipment. Restart the UPS system. If the problem persists, contact Tripp Lite for service. Bypass Overload: Reduce the load supported by the UPS system by unplugging some equipment. Either wait for the UPS system to recognize the load reduction or restart the UPS system. If the problem persists, contact Tripp Lite for service. Battery Voltage Too High: Restart the UPS system. If the problem persists, contact Tripp Lite for service. Note: All other error codes indicate internal fault conditions. Restart the UPS system. If the problem persists, contact Tripp Lite for service. 13 201102140 932835.indb 13 3/29/2011 4:50:22 PM
