Cyberpower UPS - 4 beeps
wrote in message ... Any one using Cyberpower UPS's which have failed to the 4 beeps which the manual only states to check with Cypberpower on possible repair via warranty. Any one determined what the condition is that causes the 4 beeps? Battery has gone bad? Internal Fuse? I have one of the Cyberpower 500SL that after working great for about 2 years, after returning home from one of the numerous power outages I found it was dead, and would not reset. It just makes 4 beeps and the battery outlets are dead, no voltage. Cyberpower was, well, less than informative about what caused this problem.I figure its either the battery needs replaced or there is an internal fuse that has blown that needs replaced. As from the indications from Cyberpower its repairable at a cost, so it doesn't seem to be a total loss. Any one diagnosed this situation and found an answer. I would like to repair this unit and put back into service if its a simple battery change or internal fuse repair. The lack of a substantial answer from Cypberpower just to make a buck on a repair annoys me. If everything is dead and still connected to a voltage source then check the output to the batteries. If there is none, remove the battery and see if that makes a difference. If you have output then it might be the battery. With these lower powered unit it is hard to tell when they crap out. I will bet on either a charging circuit or battery problem. As for fusing I am not familiar with Cyberpower. Might be time to consider a new one from another company. |

Many types of UPS's will not restart if the batteries are dead. Replace the
batteries to test. If you want to test the batteries you have, they must be load tested, and would think you do not have the proper set-up to do this type of test. The UPS charger, and start-up circuits respond to the condition of the batteries. If the batteries are not working properly, the logic control sees them as defective. For safety reasons, the UPS will remain shut down until this is corrected. An error will be indicated. -- Jerry G. ===== wrote in message ...

If you want to test the batteries you have, they must be load tested, and would think you do not have the proper set-up to do this type of test. Perhaps a DMM to measure voltage,and a 55W headlight bulb? Might give a crude good/bad indication.If it lights up the bulb nicely,and the voltage doesn't sag too much,it should be okay.. But this is assuming it's charged in the first place.A car battery charger set to trickle or low should be an okay charger to use,just don't charge it too long,or let it get hot,or vent or anything like that.
