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.

SOURCE: Liebert Power Sure UPS

the battery is bad, you will need to replace the battery or the whole unit. you can find batteries on ebay. just source the model number. also depends on the size of the unit. you may need to just replace it...just a better value to do it that way.

good luck

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

Liebert gxt2-10000rt208 fault indicator and A + E LEDs on. Did anyone know this alarm?

I'm going to go on a limb and say the unit also has the bypass indicator on as well, is that correct? A=On bypass due to overtemperature condition & E=On bypass due to inverter failure.
I can't see in the picture or hear it but is it beeping also? 1 second beep every 2 seconds? Thats on internal bypass. If none of this is true then you have a tricky problem.

Hi, here is the error codes that I could find for you, it seems you are overloading the inverter. That means you cannot connect a kettle or other heavy load to the output. See all error codes below, hoep this helps.

Problem: The AC load will not operate, error code shows on digital
display and alarm is sounding.
Error Possible Cause Solution
E01 Low voltage shutdown because battery is discharged.
Recharge battery. Shorten cables or use heavier cables.
E02 Over-voltage shutdown because of high input voltage.
Verify the charging system is properly regulated and the battery
is 12 V nominal.
E03 The AC product(s) connected are rated at more than the
inverter's continuous power rating; overload shutdown has
occurred. Use a product with a power rating within the inverter's continuous power rating (see Table 3).
E04 The inverter has overheated due to poor ventilation.
Overheating shutdown has occurred.Turn inverter off and allow to cool for 15 minutes. Clear blocked fan or remove objects covering unit. Move the inverter to a cooler place. Reduce load if continuous
operation is required.
E05 The AC products connected have a surge power that exceeds
the Digital Inverter's surge capability or the AC products connected are short-circuited and shutdown has occurred.The products exceed the inverter's surge capability. Use a product with a starting surge power within the Digital Inverter's capability.

Powering down

your not very clear but here is what I'm assuming your saying.

Pins 5 & 6 - Any-Mode Shutdown

1. Pin 6 of the 9-pin communication connector is used for "Any-Mode Shutdown"

of the UPS output. This control input may be used in special applications

to disable the UPS output power-both Inverter and Bypass.

2. The Options tab allows the behavior of the Any-Mode Shutdown feature to

be modified. When the program opens, or the REFRESH button is pressed,

the UPS setting is read by the configuration program and displayed.

Auto-Enable Output

Pin 6 Logic

If version 1.6 (or later) is used with an earlier Liebert GXT2U model (with an

earlier UPS firmware version), the Any-Mode Shutdown features cannot be


If the configuration program is used with an earlier UPS model (with an

earlier UPS firmware version) that does not support the modification of these

settings, the Options tab will display a reminder of the factory default

settings. These cannot be changed.


Note that when this option is selected and the UPS output is

disabled using Pin 6, the UPS output can turn on automatically

and without warning if the Pin 6 connection is changed.


DO NOT CHANGE THIS OPTION from the factory default

setting unless you are ready to install a normally-closed

connection between Pins 5 & 6. This connection must be

maintained to use the UPS or to use the configuration program

again, including the ability to change the UPS setting back to the
default setting using the configuration

The UPS only flashing the "bypass-led" and beep sound, but it doesn't put out any voltage to use.

You have a major fault. Try to reset the logic. UPS has to be off including the batteries. Call me at Gruber Power Services for free tech support. 800-658-5883 x256 ask for Eric

The Check Engine light will light when the ECU stores a trouble code.
Counting the Flashes
To retrieve trouble codes, turn the ignition key to the "on" position with the engine OFF.
The Check engine light will flash many short blinks. The total number of blinks equals the code number. For example, flash,pause, flash,flash = code 12.If more than one code is stored, the Check engine light will flash the codes in sequence (lowest to highest) with a pause between each code. The codes will repeat until the key is turned to the OFF position.

Power went off and then tv will not start. It is fitted with a surge protector

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

99 Saturn SC1 ''Service engine soon'' light is on.

Did you get the code that triggered the SEL? If you know that, it will be easier to diagnose your problem. You can do it without a tool on the old saturns. Just need a paperclip. :

Use a paper clip to jumper Terminal A and B of the ALDL *Assembly Line Diagnostic Link* which is above your left knee.
Terminal A is an interal ground and is the top right terminal in the connector. Terminal B is directly adjacent and to the left of Terminal A.

Turn the ignition to ON.

All codes are 2 digits between 11 and 99. Codes are displayed on the SES light by flashing the light with short and long pauses to distinguish digits of one code from digits of another. The short pause is used between digits of the same code, long pauses are between codes. Also, each code is flashed three times before going to the next code.

For example, the sequence of code 12 will be: flash, pause, flash-flash, long pause, then repeat 2 times. If Code 12 is not displayed, the self-diagnostic pogram i snot functioning properly.

If only Code 12 is displayed, no system malfunctions have been stored.

Any existing system fault codes are displayed in order from low to high, except for Code 11.

On vehicles with an automatic transaxle and on which exist stored transaxle codes, Code 11 will be displayed last, then the SHIFT TO D2 light will begin flashing transaxle codes of flags.

When all engine codes have been displayed, Code 12 will flash again.
