My company has a CP1K/2 UPS used to back up a computer attached to a printing press. The UPS no longer seems to function at all. I have checked the input voltages, and there is no problem there. I tried resetting the breaker, but that did nothing. I even double checked that the On/Off switch was in the ON position. No indicator lights are showing.

I could use any suggestions, or possibly information on obtaining a replacement or repairing the current one.

Brain,
The CP1k\2 may have taken a electrical surge.
Step 1 Brain have you had a chance to take the cover off of the ups?
What you are looking for inside is any indication of burnt components on your PCB board.
If you do not see any indication of burnt components.
Step 2 Brain the very next thing to consider is the age of your batteries. Has your company replaced the batteries?
Step 3 Brain what is the serial# located on the back of your UPS?
This serial# will indicate the age of your UPS. It is very important that you transpose the exact serial# off the back.
Please get back to me with that information.

I just now cracked the case. No burnt components are apparent.

The batteries are likely to be the originals. Each individual battery only shows a voltage of .6v, which is either a state of extreme discharge or just plain bad batteries. The whole array of batteries shows only 3v. I will replace these batteries and see if that clears the problem.

The serial number is: 3A708607G0011 SW
The part number is: 9102-5110-00

The batteries solved the problem. When we weren't getting any response, I just assumed it had to have been something more. Thanks for the assist.

This morning, the CP1K/2 started beeping. It no longer appears to be providing backup power to the system. The indicator lights are working, but do not seem to indicate any fault. What's wrong now?

Brain,
Whenever the power dips below 184 volts then unit goes into battery mode; you will then hear the unit beep every ten seconds and you should see a light on inverter. When the line voltage returns to normal, then the Line AC light located to the left of the inverter light should appear green. At this point you should be okay. Do you have a output on battery mode?

When you completely unplug the UPS, it shuts down entirely after a few moments. I am fairly confident that it was working yesterday for a little while. Could the problem be heat related? The room is maintained around 75-80 degrees F.

The line and inverter lights stay green when plugged in. When you unplug from line power, it shuts down after a moment or two.

Brian,
1. What type of batteries did you purchase?

2. Please disconnect the positive lead and then place your voltage meter across the negative lead and the positive lead you disconnected. I need to know what the voltage across this point is. You should see 68.5 volts, then read the voltage across the each battery.

3. At that Heat factor you will be in a safe operating condition.

I purchased 12v 7Ah batteries from the local heavy battery store.

Each battery measures 15.3v. The whole array of batteries measured 77.5v. The UPS shut down as soon as I disconnected the positive lead. Measuring across that lead to the negative lead resulted in 0v.

New symptom: Now, during power up, as soon as it tries to switch from bypass to the inverter, it dies with a fault light. Lights 1 and 3 on the Load Indicator are lit.

Thank for your help!

Brian,

What is the name brand is what I meant.

Each battery measures 15.3v. The whole array of batteries measured 77.5v. The UPS shut down as soon as I disconnected the positive lead. Measuring across that lead to the negative lead resulted in 0v.

From this symptom it sounds like the charger has gone out. You should be measuring about 68v when you disconnect the positive lead.

New symptom: Now, during power up, as soon as it tries to switch from bypass to the inverter, it dies with a fault light. Lights 1 and 3 on the Load Indicator are lit.

The board has problems; you need either to send it in for repair or trade it in for new unit. Look at our trade-in program at the address below. [url=http://www.minutemanups.com/products/trade.htm]http://www.minutemanups.com/products/trade.htm[/url]

OK, that's what I figured. Who do I contact for repairs?

The batteries were "Power Source" brand. That is what the local battery shop labels them.

Thanks once again!
