Unhoooked and moved system around. re-hooked all equipment and when I turn it up, system screen indicates "overload". did this with both DVD player and Ipod. what is causing this to happen.

You need to replace the IC Amplifiers that is near the channels when you open the player (make sure it is NO LONGER under warranty or else you'll void it). The cause perhaps is that your speakers have been shorted.

I think you have a defective alternator and the low voltage is the problem.

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.

This sounds like a battery issue, test the battery by itself....

Tell us more details about the two pairs of speakers and exactly where they're attached. You may have a dangerously LOW impedance load if you're running them together (parallel).

Page 9:

SP A/SP B/SP A B Lights up according to the speaker system used (page 34). However, these indicators do not light up if the speaker output is turned off or if headphones are connected.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

These beep error codes may help you.

Are we to assume it was working before the move?

It's telling you it thinks tghere's a short on the speaker outputs. With NO speakers, that is bad.

From the User Manual:

“OVERLOAD/CHECK BATTERY” LED: this red LED lights continuously after a self-test to
indicate the capacity of the battery-supported outlets has been exceeded. To clear the overload, unplug some of your equipment from the battery-supported outlets; then use the ON/OFF/TEST button to run a Self-Test. If the UPS continues to detect an overload, remove more equipment and repeat the self test until successful.

CAUTION! Any overload that is not corrected by the user immediately following a self-test may cause the UPS to shut down and cease supplying output power in the event of a blackout or brownout.

The LED flashes to indicate the battery needs to be recharged or replaced. If the LED flashes (and a continuous alarm sounds) during a prolonged blackout or brownout, the UPS’s batteries are nearly out of power; you should save files and shut down your equipment immediately.

If the LED flashes following a UPS self-test (after the UPS is turned ON), it may indicate that the battery needs to be replaced. Allow the UPS to recharge continuously for 12 hours; then use the ON/OFF/TEST button to run a Self Test.

If the LED continues to flash, contact Tripp Lite for service. Should your UPS require battery replacement, visit Tripp Lite on the web at www.tripplite.com/support/battery/index.cfm to locate the specific replacement battery for your UPS.

Hope this helps!

Have you checked your wiring connections? Wires could possibly be touching each other making it short out and giving you that "Overload". If not that then I would say it could possibly be a fuse that has gone bad inside. ??? Just some suggestions. The reason I say that it could be the wiring is because when I hook up a system and the wires accidently touch each other it overloads the system past a certain volume. Again I would check my wires first and move on from there.
