Can I know how to set the Voltages and others parameters using the UPS screen?

call the ups engineers for an answer to the problem when connected to solar power
there may be a problem in that solar panels produce various voltages during the day ( depending on the cloud coverage ) and the ups requires a reasonably steady input voltage to operate properly
I have found the eaton ups product to reliable so the suggestion to talk with the engineers to ensure that the system is compatible with the solar set up would be to your advantage

From the user manual: http://lit.powerware.com/ll_download.asp?file=Eaton%20FERRUPS%20User%20Guide.pdf page 108.

The output voltage is below the alarm setting as determined by setup parameters 59 and 60.

Verify the output voltage using a voltage meter. If correct, verify setup parameters 59 and 60. If alarm condition continues, bypass the UPS and turn the UPS switch off. Call your service representative.

The type of fan can be very different between two similar UPS.
The easiest way is to open the UPS and watch for.
Some UPS requires exactly the same fan, and if they take too little or too much current UPS think that it is wrong on the fan and alarms!

Need more info. What are the measurements on the input to the UPS. What is the total load you have? What other alarms are displaying? Check the input power to UPS. Also make sure the UPS is and will work for the correct voltage (Input of UPS) some UPS's are selectable voltages.

The only way to set this is to connect to the ups via serial port and have the program APC uses to set the parameters on the UPS. THis is the only way.

For APC smart-ups models, you need to do a UPS calibration after you change the battery. You need to change the UPS parameters to removed the flashing lights on the front panel of the UPS, usually you need to change the 0 parameter to its default state to remove the flashing lights.

Taken from the MGE UPS SYSTEMS, Network Management Card Installation manual (34003641EN/AD)

Run Hyper Terminal on a PC running Windows (9x, Me, NT4.0, 2000 or

higher).

◗ Connect the card to the PC using the cable supplied.

◗ Set up the terminal with the following communication parameters:

◗ 9600 bauds. ◗ 8 data bits.

◗ 1 stop bit. ◗ no parity.

◗ no flow control.

◗ ASCII: "echo typed characters locally" option disabled.

◗ Press the Carriage return key. The configuration menu is displayed.

◗ Enter the password (MGEUPS by default).

◗ The main menu is displayed.

◗ Select one of the items in the configuration menu.

Via the serial link or Telnet

◗ Select the "Agent configuration" command by entering 1.

◗ Select the item numbers and modify all the IP parameters (address, mask, gateway).

◗ Once all the modifications have been made, exit following the instructions on the screen.

Restarting the card Via the serial link or Telnet

◗ Select the "Restart agent" command by entering 6.

◗ Then follow the instructions on the screen.

Restoring the default parameters Via Telnet or Hyper Terminal

◗ Select the "Agent configuration" command by entering 1.

◗ Select the "Reset configuration to default" command by entering 5.

◗ Then follow the instructions on the screen

if this comes sometimes and goes, this means that the power to ups is sometimes deviating from the specific ups input range, hence the ups is rejecting it. mesure the input voltagesand frequency with a multimeter and check whether they match the specified ones in the ups manual. aslo with some ups there are switches that you use to set the input voltages or number of phases in the ups input. check the manual to see whetther your ups has such.

Hi, Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards. P.S. The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.

Very likely, "would this also explain why none of the indicator leds are working?"...the dead batteries are your problem. you can try this test, since you had it opened: 1.) disconnect internal batteries, label the wires by terminal location. 2.) connect (2) 12 volt car batteries to same exact wires that you just disconnected, noting correct polarity. 3.) power up UPS. if everything ok, then buy 2 replacement batteries for UPS. if not ok, buy new UPS after through search inside UPS reveals no blown fuses or other faults including poor wire connections.
