Chapter 3 Operation

This chapter details how to operate the program, including read/config UPS settings only and changing UPS settings.

This program can monitor the UPS settings while the UPS is operating in any mode. If this program is only used to

read/config the present UPS settings, you do not need to use any buttons except the Cancel button to close the

program.

To change the UPS settings, there are three conditions: canceling the settings, restore the settings and cha nging the

settings.

If you decide not to change the UPS settings after modifying the displayed settings, close the program using the

Cancel button, and the settings are canceled.

If you decide to restore the UPS settings after modifying the displayed settings and prior to select OK or Apply button,

select the Refresh button to restore the UPS settings to the existing values stored in the UPS.

Requirements on the UPS

All UPS settings can be changed when the UPS is in Standby mode (with AC input power available). Pay attention to

the following two conditions:

 Settings on the UPS Tab and Options Tab can only be changed with the UPS in Standby mode.

 Settings on the Battery Tab can be changed with the UPS in Normal or Standby mode.

If the UPS is in Normal Mode operation, press the OFF button once to put the UPS into Bypass Mode. Once the UPS

is in Bypass Mode operation, press and release the OFF button two distinct times (for about a second each time) to

place the UPS in Standby mode. This will disconnect all power to the load.

Saving the changes

Changing any value or selecting/deselecting any setting in the configuration window will not immediately change the

settings in the UPS. You may modify the displayed settings until you are satisfied with the new proposed changes.

After that, you can save the values by selecting either the Apply or OK button.

 The Apply button sends the new settings to the UPS without closing the program.

 The OK button sends the new settings to the UPS and closes the program.

Whenever the value is successfully saved, the message will be displayed, as shown in Figure 3-1.
