UPS doesn't turn on (when I press a button a short beep sounds and LED flashes about half a second)

Hi,

if your model has a mute/test button, please press this for 3 or 4 seconds to stop the beep. The beep usually indicates an approaching power shutdown of the device and allows you to save any files that are currently in use prior to this shutdown.

Thank you.

Hi Tania,
Have you gone through this checking sequence.? it's from a Panasonic a/c manual. It could be something as simple as a clogged filter. Once you have rectified the fault, you will probably have to clear the fault code as described at bottom below, before it will condescend to work again.

• Once error occurred during operation, the unit will stop its operation, and Timer LED blinks.
• Although Timer LED goes off when power supply is turned off, if the unit is operated under a breakdown condition, the LED will ON again.
• In operation after breakdown repair, the Timer LED will not blink. The last error code (abnormality) will be stored
  in IC memory.

14.2.2 To Make a Diagnosis

1. 1 Timer LED starts to blink and the unit automatically stops the operation.
2. 2 Press the CHECK button on the remote control continuously for 5 seconds.
3. 3 "- -" will be displayed on the remote control display.
   Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4. 4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed and signal will be transmit to the main unit.
5. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main unit.
6. 6 When the latest abnormality code on the main unit and code
   transmitted from the remote control are matched, Power LED will
   light up for 30 seconds and a "beep" sound (continuously for 4
   seconds) will be heard. If no codes are matched, Power LED will light up for 0.5 seconds and no sound will be heard.
7. 7 The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5 seconds or operating the unit for 30 seconds.
8. 8 The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.

14.2.3 To Display Memorized Error Code (Protective Operation)

1. 1 Turn power on.
2. 2 Press the CHECK button on the remote control
3. 3 "- -" will be displayed on the remote control display. Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4. 4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
   and signal will be transmit to the main unit.
5. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main
   unit.
6. 6 When the latest abnormality code on the main unit and code transmitted from the remote control are matched,
   Power LED will light up for 30 seconds and a "beep" sound (continuously for 4 seconds) will be heard. If no
   codes are matched, Power LED will light up for 0.5 seconds and no sound will be heard.
7. 7 The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5
   seconds or operating the unit for 30 seconds.
8. 8 The same diagnosis can be repeated by turning power on again.

14.2.4 To Clear Memorized Error Code after Repair (Protective Operation)

1. 1 Turn power on (in standby condition).
2. 2 Press the AUTO button for 5 seconds (a "beep" sound is heard) on the main unit to operate the unit at Forced Cooling Operation Mode.
3. 3 Press the CHECK button on the remote control for about 1 second with a pointed object to transmit signal to
   main unit. A "beep" sound is heard, and the Error Code is cleared

I believe you will find that your battery is either dead or shorted.

Changing the battery

If your Tripp LIte Omni 1000 LCD display a fault icon and beeps after changing the battery, try the advice given by the buzzerman which worked perfect in this case:


1. Turn the UPS on. Press and hold the ON/OFF button for one second.

2. Run a Self-Test: Press and hold the MUTE/TEST button for two seconds (until beeps several times). The test will last 10 seconds. All LCD Display icons will be illuminated and the alarm will sound. At the end of this process the fault icon and the beeping turned off.

1. Four beeps every 30seconds (On Battery LED will be illuminated)
This alarm indicates that the Battery PowerSupplied outlets are now supplying battery power as opposed to power from theutility. If the UPS determines that the input utility power is unsafe for yourcomputer equipment, the UPS will switch to battery power.
Note: Ifthe power disturbance is brief, you may only hear one or two beeps.

2. Continuous Beeping (On Battery LED will beilluminated)
This alarm indicates that a Low Batterycondition has been reached and that the UPS will soon shutdown. Once the UPStransfers to On Battery operation, it can only stay on battery for a limitedamount of time. The UPS will sound this alarm about two minutes before thebatteries are totally exhausted. Once exhausted, the UPS will shutdown and turnoff its output power to your equipment. If you hear this tone you shouldimmediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (BackUPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected anOverload condition after it has performed a self-test during start-up.

4. Continuous Two-Tone Beep
This alarm indicates a severe Overload wasdetected while the unit was on-battery operation. This tone will continue tosound until the unit shuts down.

5. Continuous Tone (On Battery LED will beflashing)
This alarm indicates that the battery-poweredoutlets are overloaded.

6. Continuous Tone (On Line and On BatteryLEDs flashing) Back UPS OFFICE 350,400, and 500 ONLY
This alarm indicates that an internal UPS faulthas occurred.

Battery not connected properly. Check that the battery connector (rear panel) is fully engaged.
Press the on/test button once to power the UPS and the connected equipment.
Make sure UPS has nothing connected to it. Check the Fuses for the battery inside in the back of the UPS
Unplug UPS and batteries. Push the on button to clear the logic. It may or may not flash the LED's Once the fuses are checked, check the logic boards for any burn or discoloration.

Automatic: The UPS performs a self-test automatically when turned on, and every

two weeks thereafter (by default). During the self-test, the UPS briefly operates the

connected equipment on battery.
Manual: Press and hold the button for a few seconds to initiate the self-test

REPLACE BATTERY LED ILLUMINATES

Replace Battery LED flashes and

short beep is emitted every two

seconds to indicate the battery is

disconnected.

Check that the battery connectors are fully engaged.

Weak battery. Allow the battery to recharge for 24 hours. Then, perform a self-test. If the

problem persists after recharging, replace the battery.

Failure of a battery self-test. 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.
