Subsequent tests will occur at every Battery TestInterval after that.SC300: Control Processes >Battery TestDCTools/Web: ControlProcesses > Battery TestInterval The time between scheduled battery tests. The intervalperiod begins at the start of a battery test. Zero disablesscheduled battery tests. Zero also disables the 48 hourlockout following an ac supply failure, allowing animmediate manual test.Test Duration The maximum time a Battery Test process will beactive. The battery test will pass if the bus voltageremains above the Battery Test Termination Voltagefor the duration of the test.TerminationVoltageIf the bus voltage drops below this value during aBattery Test, then the test fails.Prevent BatteryTestChoose whether the alarm Battery Fuse Fail shouldprevent Battery Test starting.EqualizeEqualize charges batteries at a higher voltage after they have been fully charged to ensure that allindividual cell voltages are the same, that electrolyte is distributed evenly, and that sulfate crystalbuildup on the plates is reduced.Equalize can be scheduled to occur at regular intervals and/or can be started/stopped manually. Refer to the battery manufacturer's instructions before using Equalize. If a Digital Input has the function "Start Equalize" then a manual equalize cycle will start whenthe Digital Input becomes active.If Equalize cannot start at the scheduled time (for example when there is no ac supply) then its statewill be Pending and it will start as soon as conditions allow. Use Stop Equalize to cancel a PendingEqualize.► To enable Equalize (or to start or stop Equalize manually)• Use the SC300 keypad to go to: Control Processes > Equalize.• Or, in DCTools/Web go to: Control Processes > Equalize.► To use an external relay contact to activate an Equalize (optional)• Connect a voltage free relay contact or switch to any Digital Input.• In DCTools/Web go to: Digital Inputs.• Configure the selected Digital Input and set Function to Start Equalize.► To use a Smart Alarm to activate an Equalize (optional)• Configure a Smart Alarm as required to activate Equalize.• Set Activating Smart Alarm to the Smart Alarm Number.
