Well, here's the manual and I can find no numerical alarm codes in this manual.

Cannot find an alarm code list.
This is a good manual- http://lit.powerware.com/ll_download.asp?file=164201626_9355_30_UPS_RevC-Rel.pdf.
Here is a source for documentation- http://powerquality.eaton.com/products-services/backup-power-ups/9355.aspx?cx=3&GUID=1FFC6155-2FD6-4350-967C-3B23A88CBC32.

Bypass failure is the same as your input unless you have a dual input. You lost power and the UPS did not hold the load because the batteries are bad. Replace the batteries and you will be ok.

I suggest you give Eaton a call:
Toll Free: 1 800 843 9433
International: +1 919 871 1800
E-mail: LargeUPSTS@Eaton.com
You can view the manual here in the docmentation tab: http://powerquality.eaton.com/products-services/backup-power-ups/9355.aspx?cx=3

Here is the documentation page for the Plus 36: http://powerquality.eaton.com/Products-services/legacy/plus-info.asp The Powerware Plus 36 can be serviced but it is a legacy product that is no longer manufactured. Eaton purchased Powerware and retained the service organization so there are lots of people trained to service this unit. For a replacement unit, you'd probably be looking at the Eaton 9355: www.eaton.com/9355 For Plus 36 service, here is the contact info: Toll Free: 1 800 843 9433

The Batts can be charged externally, then refitted, usually I extend the DC cables so I can work with the batt outside the unit. This is ONLY to be done if you understand the risk and what may happen if you get it wrong.

Batts are always live and can cause fire/explosion/severe burns if shorted!
IF YOU ARE NOT SURE THEN GET SOME EXPERIENCED HELP!

OK so the UPS will not normally recognise a very low batt pack, that is the reason you can not start the test, this test will back of the rectifier so the batt pack takes the load for a short period.

If the batt pack is out of range then this will make the load go off, so the UPS is designed not to allow the test,unless the batt is at the right level.

If you can get the batt pack up close to normal then the unit will recharge it to full.,Wait until it is fully charged before testing.
If this is sucessful the cyle the batt a few times allowing it to reach around low batt warning before recharging. This will assist the batt in recovery. During this process if possible monitor with a test intrument(fluke 123 or 43B will do) the batt pack discharge curve , once the batt pack has dropped to its charge level from float, it should be a smooth decay.
depending on the state of the batts you may be ok, if there are weak ones in the string then you may have to replace all of them depending on the age of the batt pack.

MAKE SURE YOU ARE VERY CAREFUL WITH BATTERIES, THEY ARE VERY DANGEROUS, AND ALWAYS LIVE!

Check you manual for safety procedures, BEFORE working on Batteries.


hope this helps
