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.

My problem with Karcher K2-59M is doesn't switch off when releasing spray trigger and it leaks water from two small holes in water inlet tube. I have stripped the washer down but find no solution. Also...


these units normally use a flow switch which actually feeds the pump motor failure to shut down causes overpressurization in pump head causing pump failure oil is normally sealed replacing the oil, pump has to be separated from motor and possible seal replacement unless u have a way to inject the oil through the lip of seal with out damaging it.

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault.
A faulty charging circuit will not charge the batteries and will also cause a fault condition.

Ds problem


In a computer, loss (or failure to retain) settings like these are caused by a faulty CMOS battery. I haven't taken apart my DS yet (cannot find my tri-wing screwdriver), but I haven't found evidence of one in the DS. So I would say these are the most likely causes:
1) DS uses a solid-state chip (requiring no power) to hold data, and that chip is defective, or
2) The battery that supplies power to hold the data is defective, whether it's a button cell, built-in, or the easily-replaced Li-Ion.

If this is a brand-new DS, try charging the battery for a while first. if it's an older one that you've had and used before and this problem only recently surfaced, I would try replacing the battery first (borrow a friend's), and if that doesn't work, the unit may need to be serviced by a professional. Keep your ear to the ground, and hopefully someone who actually knows a fair bit about DS repair may have better advice for you!

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
