All Rights Reserved.IPN 997-00012-63C August 2011Scheduled Battery CharacterizationUse the following procedure to schedule regular Battery Characterization discharges. Each Battery Characterization discharge will update the characterization data and ensure theBattery Time Remaining value is as accurate as possible.1 Check that all battery parameters are set to the correct values. See Batteries Configurationon page 37.2 Enable Battery Current Limit (see details on page 15).3 Check that the load current is at least 2% of the C10 capacity of the batteries (BatteryCapacity) and 150% of the Battery State Threshold. See Batteries Configuration on page 37. If the load current is less than 10% of the C10 capacity of the batteries, then BatteryCharacterization will take longer than 10 hours.4 In DCTools go to: Control Processes > Battery Characterization. Set the following parameters:Battery CharacterizationEnable: EnabledEnd Voltage: Set to the voltage per cell when the battery is regardedas fully discharged.In general, use the same value as for the LVD DisconnectVoltage (see LVD Configuration on page 29). End Voltagemust be at least 0.02V/Cell above the Minimum SystemVoltage per cell. The Minimum System Voltage is viewable in DCToolsat Control Processes > Voltage Control. It is notconfigurable.Interval: Set to the required interval between scheduledcharacterizations (at least 90 days to avoid excessivebattery cycling). Or, set to zero if only manualcharacterizations are required.Lockout: Set to the period when a characterization will beinhibited, after an ac supply failure.During any subsequent battery discharge the SC100 will display an estimate of the Battery TimeRemaining and the State of Charge (SOC). See Battery Time Remaining on page 37.Input/Output (I/O)The following section describes the I/O functions available with a single IOBGP I/O board. Additional SiteSure-3G input/output (I/O) modules or IOBGP I/O boards cannot be connected tothe SC100.
