Liebert 610 manual Operation

Operation

•System Configuration—This screen displays the current configuration of the UPS system. It also enables the operator to reset the date, time, dial-out phone numbers and System Options. System Options include Temperature-Compensated Charging, Customer Alarm Definitions, Auto Restart and Battery Load Test. The operator can view, but cannot change, any of the settings unless the Interlock (Security Access) button is pressed.

•Limit Settings—This security access display shows the present UPS system alarm limit set- tings. The operator can view the settings, but they should not be changed without consulting Lie- bert Global Services.

•Load Transfer Procedures—This screen specifies all of the steps required to manually transfer the critical load between the UPS and the bypass source. Comparisons of the voltage, frequency and phase synchronization of the UPS output and the bypass line are also illustrated to aid in the transfer or retransfer procedure.

•Start-UpProcedures—This two-page screen lists step-by-step procedures to start the UPS.

•Shutdown Procedures—This two-page screen lists the proper sequence of steps to shutdown the UPS for maintenance or repairs. The steps instruct the operator to transfer the critical load to bypass, open the battery circuit breakers and open the UPS input circuit breakers to shut down and isolate the system. The critical load will remain on bypass power unless circuit breakers out- side the UPS are also opened.

•Battery Time—This graph displays the projected battery voltage drop caused by a battery dis- charge over time. During a period of battery discharge, the Series 610 calculates the battery time remaining based on battery rating, initial battery condition and actual connected load. The UPS continues to update and display both rated (theoretical) and calculated time every 6 seconds. This enables the operator to immediately see the effects of load shedding on time remaining and to accurately assess his power resources.

•Meter Calibration—This security access screen enables an authorized Liebert field-service engineer to adjust and calibrate the UPS metered functions. The operator can view, but should not change, any of the settings.

•Battery Equalize—The battery equalize screen lets the operator change the battery equalize recharging mode from manual to automatic and to observe or change the equalize time. Battery equalize charge voltage is higher than battery float charge voltage.

NOTE

Do not use battery equalize charging with sealed-cell (VRLA) batteries. Refer to the battery manufacturer’s manual, available on the manufacturer’s Web site, for specific information about equalize charging.

•Customer Alarm Definitions—This optional screen allows the operator to define alarms for conditions external to the UPS, battery or switchgear.

•Battery Test (Optional)—The battery test screen allows the operator to perform manual bat- tery tests to determine the general condition of the battery system. The results of the last 10 tests are recorded in non-volatile storage and can be retrieved through the battery test results screen.

•Battery Temp Compensation Charging (Optional)—The optional battery temperature sens- ing unit, when installed, automatically reduces the float charge voltage in response to increases in battery temperature. The nominal float voltage is 540VDC (2.25 volts per cell) at 25°C. This float voltage is automatically reduced 5VDC for each temperature rise of 5°C. The LCD indicates whether the temperature compensation circuit is active.
