Introduction and Requirements

WELCOME TO THE GXT 2U™ CONFIGURATION PROGRAM

This is a new feature included with the new UPSstation GXT 2U™ line of UPS. SeveralUPS settings that were previously not available, or required custom manufacturing, maynow be modified using this program. For most users, the factory default settings will beadequate. This manual will illustrate the available features available for modification, aswell as the factory default setting.

WHAT YOU CAN DO WITH THE GXT 2U™ CONFIGURATION PROGRAM

1. Select one of five input/output voltages to match voltages found around the world.2. Disable Auto-Restart.3. Disable the Line-Neutral-Reversed/Missing-Ground receptacle wiring alarm.4. Select frequency converter operation with a fixed output frequency of 50 or 60Hz.5. Set the Low Battery Warning alarm time from 2 to 30 minutes.6. Disable the Auto-Battery test.7. Set the Auto-Battery test to 7, 14, 21, or 28 days.8. Select the number of external battery cabinets connected to the UPS to adjust the

remaining runtime calculations reported by the UPS Liebert software products.

This program is compatible with UPS models beginning with “GXT2-”, as in “GXT2-2700RT-120”. It is not compatible with earlier versions of UPStation GXT™ UPS.

WHAT YOU WILL NEED

In addition to the GXT 2U™ UPS, you will need the configuration program diskette andserial cable included in the UPS accessory box. A Windows 95®, 98®, or NT® computer isalso required to run the configuration program.

GXT 2U™ Configuration Program Installation

An easy-to-use installation program will streamline the installation of the configurationprogram. Choose the START button on the Toolbar and select RUN. Type “A:\Lbt_gxt2-1.5.exe” and choose OK. You may also use the Windows Explorer to view the contents of the diskette and double click on “Lbt_gxt2-1.5.exe”.

When you see this PreSetup window,select OK.

This will open the main installationscreen shown on the right. Click NEXT

or hit RETURN to continue.

It is recommended that the defaultinstallation options be used, but youwill be given the option to makemodifications to the standard entries.

The installation program will also install an Uninstaller along with the Liebert UPS program.

Establishing Communication Link with the UPS

Only use the serial communication cable supplied with the configuration program. If anaccessory communication card has been installed in the UPS INTELLISLOT® port, theoption card must be removed while using the configuration program.

Use the serial communication cable to connect COM1 to the DB9 communication port onthe rear of the UPS. COM2 may also be used. If the COM port of the host computer onlyhas a DB25 pin connector, a DB25-to-DB9 adapter must be added.

THE UPS MUST BE OFF and powered by the AC utility when using the configurationprogram to change any UPS setting. However, the program may be used while the UPS is

on to check the current settings. Any attempt to change a setting while the UPS is on willresult in an error message. To make sure all UPS logic is fully OFF, press the OFF buttontwice within four seconds just before using the configuration program.

Select “Lbt_gxt2.exe” from the program group to start the configuration program. Theprogram will search COM1 & COM2 for a properly connected GXT 2U™ UPS. When theUPS is found, the opening program window will display the UPS model number. If a GXT2U™ UPS is not found, the opening screen will display a blank model number and error message. If this occurs, verify the connection and that the UPS is powered (AC INPUTLED ON).

GXT 2U™ Configuration Program Features

UPS TAB

When the program starts, the following window will open displaying the model number along with the current UPS settings. This information can be refreshed at any time using

the REFRESH button.

These windows show the factory default settings for 120VAC UPS. The only default settingthat will be different on any other models will be the Output Voltage for 208 and 230VACmodels.

OUTPUT VOLTAGE

The Output Voltage shown is the

nominal input/output voltage. This isnot a voltmeter and will display thenominal voltage whether the UPS ison or off. The drop down box willshow the alternate voltagesavailable. Select the voltage that

matches the nominal utility in your location.

AUTO RESTART

The UPS will provide computer grade power during power outages. If input power isunavailable for an extended time, the UPS will shut down when batteries are depleted, or ashutdown signal is sent by the computer operating system (serial data or contact closure).If Auto Restart is enabled (checkmark in box), the UPS will restart when input power isrestored. If the UPS turns off power to the load for any other reason, manual restart is

required. Click on the box to remove the checkmark and disable Auto Restart.

L-N REVERSE DETECTION

Proper wiring of the receptacle powering the UPS is critical for safety, EMI suppression,and surge suppression. The UPS checks the outlet when first plugged in. If the Line-Neutral is reversed or the ground is missing, the UPS will not start. If a problem is detectedafter the UPS is started, the UPS will continue to operate, but the AC INPUT LED willflash. In some unique application the user may wish to disable this alarm. Except for



5

special situations, improperly wired receptacles should be immediately repaired before theUPS is put into service. Click on the box to remove the checkmark and disable this alarm.

FREQUENCY SELECTION

The UPS is normally designed for 50Hz or 60Hz operation. The factory defaultcorresponds to the model. All models are capable of being used as 50Hz or 60Hzsystems. The UPS will Auto-sense the utility frequency when first plugged in and set the

nominal frequency to match. Therefore, for all normal use the Auto Sense button shouldbe selected.

Some special applications require that the UPS be used as a frequency converter.Frequency Converter 50Hz or Frequency converter 60Hz may be selected.

Note that frequency converter operation disables the Bypass. If, for any reason, the UPSinverter is unable to power the load, the alternate bypass to utility power will not beavailable and power will be removed from any load.

BATTERY TAB

Battery options may be viewed and selected by clicking on the battery tab. The currentUPS settings will be displayed when the program first starts or the Refresh button isselected.

The boxes on the right show the available options using the dropdown selection boxes.

LOW BATTERY TIME WARNING

The UPS will estimate remaining operating time when on batteries. A low battery alarm isactivated if the estimated time reaches the Low Battery Time. This may be changed to anyvalue from 2 to 30 minutes.

AUTO BATTERY TEST TIME

The UPS performs an automated battery test periodically, if enabled. The factory defaultperiod is 14 days. The user may also select time periods of 4, 21, and 28 days.

BATTERY CABINETS NUMBER

If additional batteries are attached to the UPS, more accurate battery runtime estimatesare possible if the battery number and type of batteries are entered here. The new UPSmodels are designed to operate with up to four external battery packs or four long runtimebattery packs, when available.

AUTO BATTERY TEST

In some applications it may be preferable to disable the automated, periodic battery test.Click on the box to remove the checkmark and disable the periodic battery test.

GXT 2U™ Configuration Program Operation

UPS SETTINGS MAY ONLY BE CHANGED USING THE CONFIGURATION PROGRAMWHEN THE UPS IS OFF AND NO POWER IS BEING DELIVERED TO THE LOAD.

Changing any value, or selecting/deselecting any box will not immediately change thesettings in the UPS. Settings displayed by the configuration program can always berestored to the existing values stored in the UPS by selecting the REFRESH key. Valuesentered will only be transmitted to the UPS when either the APPLY or OK button isselected.

Values will only be transmitted to the UPS when the UPS is fully off and powered by the AC input. Only the AC LINE LED will be on. Attempting to change setting when the UPS ison will result in an error message. If an error message appears instructing the operator toturn the UPS off, press the UPS OFF button twice (one second each time) within foursseconds, even if the UPS already appears to be fully off.

Values may be transmitted to the UPS without closing the configuration program byselecting the APPLY button. Values may be transmitted to the UPS and the program willbe closed by selecting the OK button.

When values have been successfully transmitted to the UPS, a confirmation message willbe displayed reminding the operator to close the configuration program, first, and thenrestart the UPS.



7

Exit the program using the CANCEL button to avoid transmitting any new values to theUPS.
