10 5: TROUBLESHOOTING Use the chart below to solve minor Smart-UPS installation and operation problems. Refer to the APC web site, for assistance with complex UPS problems. PROBLEM AND POSSIBLE CAUSE SOLUTION UPS WILL NOT TURN ON Battery not connected properly. Check that the battery connector is fully engaged. button not pushed. UPS not connected to utility power supply. Very low or no utility voltage. Press the button once to power the UPS and the connected equipment. Check that the power cable from the UPS to the utility power supply is securely connected at both ends. Check the utility power supply to the UPS by plugging in a table lamp. If the light is very dim, have the utility voltage checked. UPS WILL NOT TURN OFF button not pushed. Internal UPS fault. Press the button once to turn the UPS off. Do not attempt to use the UPS. Unplug the UPS and have it serviced immediately. UPS BEEPS OCCASIONALLY Normal UPS operation when running on battery. None. The UPS is protecting the connected equipment. UPS DOES NOT PROVIDE EXPECTED BACKUP TIME The UPS battery is weak due to a recent outage or is near the end of its service life. Charge the battery. Batteries require recharging after extended outages. They wear faster when put into service often or when operated at elevated temperatures. If the battery is near the end of its service life, consider replacing the battery even if the replace battery LED is not yet lit. ALL LEDS ARE LIT AND THE UPS EMITS A CONSTANT BEEPING Internal UPS fault. Do not attempt to use the UPS. Turn the UPS off and have it serviced immediately. FRONT PANEL LEDS FLASH SEQUENTIALLY The UPS has been shut down remotely through software or an optional accessory card. None. The UPS will restart automatically when utility power returns. ALL LEDS ARE OFF AND THE UPS IS PLUGGED INTO A WALL OUTLET The UPS is shut down and the battery is discharged from an extended outage. None. The UPS will return to normal operation when the power is restored and the battery has a sufficient charge. 11 PROBLEM AND POSSIBLE CAUSE SOLUTION THE OVERLOAD LED IS LIT AND THE UPS EMITS A SUSTAINED ALARM TONE The UPS is overloaded. The connected equipment exceeds the specified “maximum load” as defined in Specifications at the APC web site, The alarm remains on until the overload is removed. Disconnect nonessential equipment from the UPS to eliminate the overload. The UPS continues to supply power as long as it is online and the circuit breaker does not trip; the UPS will not provide power from batteries in the event of a utility voltage interruption. If a continuous overload occurs while the UPS is on battery, the unit turns off output in order to protect the UPS from possible damage. THE REPLACE BATTERY LED IS LIT Replace Battery LED flashes and short beep is emitted every two seconds to indicate the battery is disconnected. Weak battery. Failure of a battery self-test. Check that the battery connectors are fully engaged. Allow the battery to recharge for 24 hours. Then, perform a self-test. If the problem persists after recharging, replace the battery. The UPS emits short beeps for one minute and the replace battery LED illuminates. The UPS repeats the alarm every five hours. Perform the self- test procedure after the battery has charged for 24 hours to confirm the replace battery condition. The alarm stops and the LED clears if the battery passes the self-test. THE SITE WIRING FAULT LED IS LIT 120V models only. Site wiring Wiring faults detected include missing ground, hot-neutral polarity reversal, and overloaded neutral circuit. LED on rear panel . Contact a qualified electrician to correct the building wiring. The UPS is plugged into an improperly wired utility power outlet. THE INPUT CIRCUIT BREAKER TRIPS The plunger on the circuit Reduce the load on the UPS by unplugging equipment and press the breaker (located to the right of plunger in. the input cable connection) pops out. AVR BOOST OR AVR TRIM LEDS LIGHT Your system is experiencing excessive periods of low or high voltage. Have qualified service personnel check your facility for electrical problems. If the problem continues, contact the utility company for further assistance. 12 PROBLEM AND POSSIBLE CAUSE SOLUTION UPS OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE EXISTS UPS input circuit breaker tripped. Reduce the load on the UPS by unplugging equipment and resetting the circuit breaker (on the back of UPS) by pressing the plunger in. Very high, low, or distorted line Move the UPS to a different outlet on a different circuit. Test the input voltage. Inexpensive fuel powered voltage with the utility voltage display (see below). If acceptable to the generators can distort the voltage. connected equipment, reduce the UPS sensitivity. BATTERY CHARGE AND BATTERY LOAD LEDS FLASH SIMULTANEOUSLY The internal temperature of the Check that the room temperature is within the specified limits for opera- UPS has exceeded the allowable tion...
