Hi Scabcmx,

Without knowing the full model number of your UPS I cannot go into specific details fully for you.. but a good test with any 'intelligence module fault' is to re-seat the module and run a self test. If the fault remains then your intelligence module is bad and you will need to acquire a new one to replace the faulty one. This can all be done 'on-line' and you should not have any downtime... assuming there is a redundant intelligence module in the unit which is normally the case. This will clear the fault.

If you would like more information give me a call: 407.380.9200.

SOURCE: I have a symmetra RM

The first thing is to make sure the interconnection between the main module and the extended run is properly making contact

Next is to verify the XR battery cabinet voltage is according the battery charging voltage (normally 137 Vdc). Power View will confirm this voltage.

My favorite is to load test the batteries module individually and make sure the batteries are good.

If there is a +/- 3 volts difference between the UPS and the extended run module E0 alarm would be indcated.

Self test failed


This could mean that you have bad batteries in the UPS. Usually when it does this test its to test the batteries. So the UPS will start a battery test, Rectifier will lower it's voltage to a set point where the UPS tell it self to go on battery. If the UPS detects that, the battery % is lower than the allow set point to perform the the self test it will stop the test immediately. This way your load is not interrupted. Also could be that the intelligent modules or power modules have a issue which again the set point is to low or out of range due to the total of load the ups has on the output compared to the total power modules that might have a problem with. The UPS is smart enough to stop its test and sends a alarm to notify you. Hope this helps. Get the manual and go into the ups and do a diagnostics on the UPS, this should identify if you have bad batteries or power modules are bad. Doing a diagnostics should not drop the load.

What parts are used to preform a tune-up


First you need a tech that is qualified and has experience in Annual PM's on this type of unit. Symmetra is a module type unit. there is hardly any "tune up' to do to this unit. Test the batteries and insure all modules all ok, this includes the intelligent modules that pull out. Review past alarms that have been recorded and insure that no major alarms are present. Do a battery test from the display interface. Clean the area around the UPS.

Symmetra LX "Intelligence Module Fault". Does


First calculate the total load of the UPS and then calculate the total load. One of the Intel Module is Primary and one is Secondary. I can't remember exactly which one is primary. Q1. There will be a LED on the INTELI MODULE flashing RED. That identifies the bad MODULE. Q2. You can remove the MODULE, but I recommend you place the UPS in Static Bypass first through the Display Menu. Also make sure the UPS is in NORMAL MODE or already in STATIC BYPASS, the LED's on the Display should indicate what mode its in. Q3. You can remove the display from the Inteli Module with out harming the load. You just can't do anything with the UPS, as to tell it to Go to Bypass (Static Bypass) or get out of Bypass, check voltages, etc. So order the part first by getting part number on the sticker off the Module, then schedule your shutdown and perform the you maintenance after hours this way you don't affect anything during business. Also don't do the repair on a Friday due to the fact its weekend and APC/Third party UPS companies will charge you a lot to come out in the weekends. FIRST DO THIS PLEASE- GET THE MANUAL FOR THIS UNIT!!!! And READ IT FIRST!! Find in the manual where it walks you through putting the UPS In bypass (Static Bypass). Follow the manual, My way of doing is to READ TWICE, OPERATE UPS ONCE!! This has help me not dump any loads. My suggestion to you is to check if unit is in Bypass (static Bypass due to the faulty module. If it is on Bypass then all you need to do is follow the procedures to place UPS in External Maintenance Bypass. If UPS is in Normal mode but with Alarms and Beeping, then Navigate through the display and find the BYPASS Mode. Then hit enter Yes on the BYPASS MODE, it will ask you again if you want to "Place UPS INTO BYPASS. Hit YES. You will hear it click. Your LED on the display should Light UPS Solid "BYPASS LED ON" AGAIN Please keep referring to the MANUAL. Once your in bypass mode (Static Bypass) then you can operate the External Bypass Switch on the bottom of the UPS. That is the Maintenance Bypass Switch. This isolate the UPS completely and your load never see's the transfer from Static Bypass to External Bypass, Because its a MAKE BEFORE BREAK System. (Make the power before Breaking the Power) Sorry to get down to simple terms, but when I work on a UPS its personal due to the fact you are responsible for the all that is on the OUTPUT of that UPS. Once on External Bypass, You can now do you module swap. Turning the UPS back on, Please follow place UPS back On Line in the UPS Manual. Also in the Diagnostics, off the display of the unit, it also identifies what module is bad including the Power Modules to the Battery Modules.

Symmetra LX16000,5.93kva; Problem;Alarm indicating power module fault.


Hi Akortic,



Without knowing the full model number of your UPS I cannot go into specific details fully for you.. but a good test with any 'power module fault' is to re-seat the module and run a self test. This only applies if you have an extra/redundant power module to support the load. If the fault remains then you have a bad power module and you will need to replace it as soon as possible. This can all be done 'on-line' and you should not have any downtime... assuming there is a redundant power module in the UPS. This will clear the fault.
