Voltage at charger terminals is maained constanthe float voltage se

8、tting.Recharge/equalize modeThe selector switch (001CC) is set to recharge/equalize. Voltage at charger terminals is maained constanrecharge/equalize voltage setting.Manual mode (with load disconnected)Voltage is adjusted manually by using a potentiometer (located on the charger regulation pred circ

9、uit board). This mode overrides the other three modes (automatic, float, recharge/equalize). Voltage adjustment range is 0 to 156 V.The operator monitors charging current by using anothotentiometer (also located on the charger regulation pred circuit board) and maains ia value not exceeding0.03 C/10

10、.GeneralUnder normal operation, the chargrovides the DC load in parallel and floats the battery or recharges it as nesary. The battery is only required to handle transient load peaks.When one charger failed or loss of ACer, all of DC loads can be change over to another charger automatically or manua
