Problem with Compaq UPS T1000h

When we have failure on electric system, our UPS T1000h take over the load of our main computer. But after 15 sek. starts our electric generator to take over the mains and then become the problem. The main fuse (10Amp.) on our UPS break down. This happens every time, when el.generator starts. Without el.generator, UPS works well.
In our organisation we have other UPS systems and all doing fine.
Thanks

I had a problem like this one, check the voltage from the generator , if the output from the generator is to high (over 240 Volts european standard voltage), the voltage protection (VDR resistors ) will brake the fuse to protect your UPS.
and also check the frequency of the generator, it has to be very stabile around 50HZ (european standard frequency)

GE LP33 UPS inverter failed to start


Dear Yared,

Did you try to give the UPS some time to recharge the batteries?
Seems like the batteries have reached their cut-off voltage and are not supplying enough voltage to the inverter.

Normally the dc boos circuit of the UPS will supply voltage to the DC BUS so maybe the problem can be found in the dc boost circuit or BUS if recharging the batteries is not helping.

Let me know.

Best Regards,


Ron

When connected to power the green light is not showing and the battery light is is always on


This indicates the battery is worn out and will not provide power in the event of a mains power failure.
To test the battery, connect a computer or some other device to the output on the UPS, and connect the UPS to the mains supply. Turn on the mains power to the UPS and power up the computer, then turn off the main power to the UPS and if the computer switch off in a short time.
This proves the battery is old and needs to be replaced.

I want to increase the ampare of my u p s what i shuold do?


If you mean how to increase the UPS capacity so you can run more equipment or for a longer time when the power goes out, you can't. You would need to purchase a larger UPS. The unit capacity is determined by the size of its storage batteries and the ratings of the electronics in its inverter circuit. Without redesigning the unit and replacing parts you can't make it give you more than its design. This is why there is such a range of UPS sizes available, and why the larger ones are more expensive.

Can i have all the basic details of UPS system


UPS come in two types, lower powered cheaper types are usually switch over power.
These units senses a power outage and then switch over to the battery power to generate mains supply. The switch over occurs in milli-secs and does not affect the computer.
True UPS types constantly run off battery power to generate mains supply so there is no switch over time lag. These units are higher powered and higher costs units.

Both type of UPS have the same components.
Battery charger.
Batteries
Inverter that converts battery voltage to mains voltage
Electronic controls

Red led on above batt sign what does this mean


Hi,
Seems like your Battery is very low. Try charging the battery for a few hours. If the problem persists, it maybe the time to get a new battery.
Like all batteries, UPS Batteries (that store electricity and let s you use it in case of a power failure) have a limited life. This life is averaged to be around 2 years. So in case your UPS has been in use for approximately that much amount of time, the battery is in a near death situation.

For instructions regarding replacing the battery, please refer to your UPS Manual.
Hope this has helped you... Please rate the answer.. Thanks...

I Have UPS 700-6000VA. It keeps changing on battery mode while on power, them reads error message bypass not available. Any help?


Bypass not available is a common alarm.

This is because the input and ouput parameters

volts and frequency do not match, suggest checking these with meter or using ups sw and comp.

Bypass will not function if either v or f is incorrect, check manual for specs.

Post more info about batt on load with mains conected please, as this could mean major fault such as rectifier failure or micro malfunction

Hope this helps, thanks for asking FixYa

APC UPS 1500 w/full load forces immediate reboot at pwr failure


Hello,

With a 980watt load the run time is only 7 minutes on a brand new battery. If you have the system on full load your run time will be much less and it has likely damaged the battery. here is the APC web site page for your model. If you are running that much equipment I think you need either a bigger UPS or another 1500 and spread the load out.

Less then 5 minutes runtime at minimal load


You gave no reasons why you thought it was simply a software setting, so I gave you a link below for some management software. The HP R3000 UPS supports HP Power Management Software (CPM) version 1.8. http://h18004.www1.hp.com/products/servers/proliantstorage/power-protection/software/legacy-software.html In addition the HP R3000 UPS also supports the LanSafe III management software (discontinued). My first question is: When were the batteries last changed? If they haven't been changed in 3 or so years, then it's probably low batteries, meaning they are old and cannot take a charge anymore.
