Question about UPS Battery Backup Systems

1 Answer

Liebert 150kva 600 series single mod 3 ph

I had the video display go out on start-up and the em. off light/buzzer smoked. The display board still has 48v and the three slot board it plugs in to (supplied by ribbon cables) has an indicator light on it that isn't illuminated. I'm not sure if it was ever illuminated or if it should be. I need to get the display up to move forward. Which direction should I go? I already tried to hook up an RS232 connection but had no luck there either. Any help would be greatly appreciated. Thanks.

Liebert gxt2-10000t230 low batt,bypass light flashing,no output,shutdown after a minute


Test outlet power by switching the unit to manual bypass and breakers off.
If power is supplied OK and the filter board repaired OK then restart the unit starting with the breakers supply to unit,battery confirm the display is on and static bypass led also on then switch back the bypass knob to normal and press the on button to switch the unit to normal.
Give the batteries time to charge 12hours then you can test the unit on backup mode.

Emerson UPStation, Liebert GXT21000RT120. 2 tower battery is continuing to alarm. Bypass light is on and AC input light is on. This happened after dropping a plastic water bottle on top of the main...


Hi Tammy, this can only be done if the load is not critical....
If load is critical then shut it down first.

On bypass you will be getting one beep every min or so
Try pressing the inverter on button, there should be a single beep, and then if all is well the inverter will come back on line. All leds will then be green.

Suggest once working that it be checked to see if it will still support load during outage.

If this does not work then please post again.

In the manual there is pages of fault diagnostics which may assist, if you don't have the manual it can be downloaded from the Emerson website.

Hope this helps,thanks for using FixYa

After battery replacement, upon power up, constant beep with fault light full on and battery light flashing. On some trys, the bypass light will also light up. No response from buttons. Unit is...


Try and push and hold the on button for about 3 sec. This will start a manual battery test. If only three of the five battery led illuminate allow the ups to recharge the batteries for 24 hours. Battery light flashing means internal battery source not available. Check battery connection, completely power down and reboot UPS

My Liebert PSA itON 600 UPS keeps beeping when i turned it on


To figure out what's wrong with the UPS, first you have to do a few things.

When calculating the rating a UPS can handle, it's voltage x amperage. If it's Watts multiply the number by 1.67 to give the rating of the device.

Add up all the devices (use the power supply rating in the computer) as well as any other device, and add them up.

If this rating was exceeded, then you have overloaded the UPS. If it was too long that you did this, then you wore out the battery.

When a UPS beeps even when not connected, that means the battery is very weak.

If the battery is more than 3 years old, it will need to be changed. If the online tests of the unit were done and the battery doesn't need replacing, then other parts of the UPS need fixing.

Check the battery.

Liebert UPStation S floating neutral failure


surprised it tried to start with amissing neutral,
this is used to reference one side of the incoming live for the control circuits
Emerson do not release diagrams, and I doubt if anybody has the correct diagram as the unit is so old. ups is really difficult to repair, even with diagrams.
I used to fix AP200 series units and I had the service manuals, they were still very difficult.

looks like your ups is toast, could be expensive but,
maybe you can find a repair tech who can get parts form other units.
