Voltage Programming Button | Liebert 1000

Controls and Indicators

6.3Voltage Programming Button

The PowerSure PSI contains a Voltage Programming button that allows the operator to select the nominal utility voltage. This setting changes the utility transfer points (low and high) of the UPS and the nominal output voltage when operating in Battery mode. The operator can select between 110, 120 and 127 VAC output. The factory-default setting is 120 VAC.

The Voltage Programming button is a push button type and is behind the plastic bezel on the front panel of the UPS. To access the button, the front bezel must be removed.

6.4Load Level Indicators—4 green, 1 amber

The Load Level Indicators display the approximate electrical load placed upon the UPS. The UPS Load Level Indicators are displayed in 25% increments as shown in Figure 12.

Figure 12 Load level indicators—4 green, 1 amber

Upon detection of an output overload condition, the amber overload (>100%) indicator flashes and an audible alarm activates. If the UPS shuts down due to an overload condition, the amber overload (>100%) indicator illuminates (see Troubleshooting section for details).

6.5Battery Level Indicators—5 green

The Battery Level Indicators display the approximate battery capacity.

The approximate battery capacity is displayed when the UPS is operating in Normal, Buck/Boost, or Battery mode.

The Battery Level Indicators are displayed in 20% increments as shown in Figure 13:

The PowerSure PSI is equipped with automatic and remote battery test features. The automatic test occurs every 14 days if utility has not been interrupted; this option may be configured by the user. Should the battery fail this test, the amber Battery Indicator will be illuminated and an alarm will sound (see Troubleshooting section for details).

The remote test feature functions with MultiLink 3.x software and can remotely initiate the battery test.

6.6AC Input Indicator—Green

The AC Input Indicator illuminates when utility power is available and within the input specifica- tions. This indicator flashes when the UPS detects a Site Wiring Fault (line-neutral reversal or neu- tral not grounded properly) (see Troubleshooting section for details).

6.7Buck/Boost Indicator—Green

The Buck/Boost Indicator illuminates when the UPS is operating in Boost mode to compensate for a low utility voltage condition. This indicator flashes when the UPS is operating in Buck mode to com- pensate for a high utility voltage condition (see Troubleshooting section for details).

6.8Battery Indicator—Green/Amber

The Battery Indicator illuminates green when the UPS is operating on battery and flashes green when a low battery condition occurs. The Battery Indicator illuminates amber when a bad battery is detected, indicating that the batteries need to be replaced (see Troubleshooting section for details).
