Powerware 9335 operation manual

Page 39

While in battery mode, the UPS will enunciate an audible horn, indicate the status change on the front panel display with the message “MAINS NOT OK”, and make an entry into the alarm event history. As the battery discharges, the boost converter and inverter constantly make small adjustments to ensure a steady output. The UPS will remain in this operating mode until the input power to the rectifier is again within the specified voltage or frequency acceptance window.

If the input power fails to return or is not within the acceptance parameters required for normal operation, the battery will continue discharging until a DC voltage level is reached where the inverter output can no longer support the connected loads. When this occurs, the unit will issue another set of audible and visual alarms indicating “BATTERY IN DISCHARGE”. Unless the rectifier has a valid input soon, the critical load will only be supported for about 3 minutes before the output of the system shuts down completely. When this occurs, the LCD display will show the message “BATTERY DISCHARGED”.

If at any time during the battery discharge, the input power becomes available again, contactors K1 and K4 are closed and the rectifier will begin to supply DC current to the boost converter and inverter. The battery SCRs will be switched off while the battery charger is turned back on to begin recharging the battery. At this point, the unit returns to normal operation.

The systems total operating time on battery will depend on many factors. Some factors that affect battery support times are battery type and capacity, number of parallel strings, environmental temperatures, age of the battery, and fluctuations in load demand during the discharge. The greater the load, the less support time the battery will provide. Decrease the load and the battery support time will generally increase.
