Question about Opti -UPS PowerES 1400 UPS System

1 Answer

UPS power goes off instantly as soon the external supply stops.

I have a V-GUARD UPS (UPS-50E) which I have been using along with my computer for a quite long time. For a few months, its not giving me the stand by power to switch off my machine safely and the power goes off instantly when the external supply ends. I had a battery replacement couple of years back. What could be the reason for this to happen? I tried hooking the UPS to the wall power outlet for a long time and it didn't help. Even the "Backup Battery Low" indicator is not flashing when the UPS is switched on. Please can you advise any steps that I can execute towards resolving this?

In our office, I have had to replace UPS batteries AGAIN two years after I replaced the original batteries in the units. I had purchased the replacement batteries locally, so I don't know if the brand of replacement batteries was not as good as the original batteries or what. But your weak battery light is not flashing ... I would try a replacement battery (if it isn't too expensive) but I know that some of the older batteries are no longer used in the newer UPS units so if the problem wasn't the battery you are stuck with a new battery and nothing to use it for.

    Also visually the batteries to see if they are cracked or bulging. If they are then you know the batteries are the culprit.

Computer restarts as soon as power goes off, its not an ups . When i manually turn off the power to the UPS, it switches / relay works fine, but if actually if there is a power outage the relay does not...


Your question is slightly confusing. Do you mean that the computer is not powered by a UPS? If the computer is not connected to the UPS, then why have a UPS? If the computer is not connected to the UPS and restarts when you turn the UPS On, your circuit feeding the UPS is overloaded and the voltage dips. If the computer is connected to the UPS, and restarts when there is a power outage, the fault may lie in the reaction of the HP 800. This unit looks to be a line interactive unit and it is not a true on-line UPS. The line interactive and battery backup (no voltage regulation) units both should have a switch to battery power time of 4 msecs, or less. If this unit is faulty and the switchover time is longer, it will not continue to hold up the computer internal power supply. If you are trying to run a laser printer on the HP unit, it won't have enough output capacity.

The unit beeps


I am getting these directly from the user manual (available here: http://www.apcmedia.com/salestools/ASTE-6Z7VAQ_R3_EN.pdf)

Issue: On Battery - UPS is supplying battery power to the load connected to the Battery outlets.

Visual Indication: Power On LED - ON (off during beep)

Audible Indication: Beeping 4 times every 30 seconds

Stops When: UPS transfers back to Power On operation, or when UPS is turned off.

- OR -

Issue: Sleep Mode - During On Battery operation the battery power has been completely exhausted and the UPS is waiting for utility
power to return to normal.

Visual Indication: None

Audible Indication: Beeping once every 4 seconds

Stops When: Utility power is restored, or if utility power is not
restored within 32 seconds, or the UPS is turned off.


All other issues are CONSTANT tones, which you did not specify, or there are no audible tones associated with it.

Strange noise comes out from the ups after a power cut


The Back-UPS Office unit has five different tones or alarms:

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

2. Continuous Beeping (On Battery LED will be illuminated)
This alarm indicates that a Low Battery condition has been reached and that the UPS will soon shutdown. Once the UPS transfers to On Battery operation, it can only stay on battery for a limited amount of time. The UPS will sound this alarm about two minutes before the batteries are totally exhausted. Once exhausted, the UPS will shutdown and turn off its output power to your equipment. If you hear this tone you should immediately shutdown your computer to prevent data loss or corruption.

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

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

5. Continuous Tone (On Battery LED will be flashing)
This alarm indicates that the battery-powered outlets are overloaded.

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

Why does my apc350 squeal when on is it the battery? the green light is on


that is the inverter inside operating. the pitch should not be objectionable, but if it continues, you may wish to consult with the maker and ask if inverter is failing early

APC back UPS 400 fails to give back up


I have the same problem with an apc smart-ups VS 650.

 

New batteries - charge in batteries is good (also tested under load).

 

When AC power fails, no power is supplied to PC connectors by the UPS.

 

UPS self test works fine. UPS does not report any problems via software - Power Management under Windows XP.
