This determines how the alarm is indicated.See details on page 55.If set to Disabled then the alarm will not activate.Threshold An analog input high/low alarm is activated if the scaled input is greaterthan/less than or equal to this value.Hysteresis The amount of hysteresis applied to the input before an active alarm isdeactivated.Digital OutputMapping AIf required, select a relay that will be operated when the alarm is active.Digital OutputMapping BIf required, select a second relay that will be operated when the alarm is active.Send Trap Depending on this setting, an SNMP Trap will be sent for this alarm, onactivation or deactivation or both, if the alarm's Severity matches the setting ofthe SNMP Trap Level (see details on page 109).Notes Type any required description. When the alarm is active the text will bedisplayed on the SC300 and included in the SNMP trap (if used).Smart AnalogsSmart Analogs provides a means to add, average or multiply analog input or system values.For instance:• Add the current to three outputs to give total “Load A” current.• Average two temperature readings to give “Average cabinet temperature”.• Subtract outside temperature from inside temperature to give “Temperaturerise”• Multiply Bus Voltage times Alternative Energy Input Current to give WindGenerator Power Smart analogs are not visible on the SC300 front panel, unless the Main Screen values have beenset to Smart Analog. Refer to Main Screen Parameters, page 14 for more details.Smart Analogue ValuesParameter Description Where to find:Smart Analog The value of the Smart Analog calculated by theSC300. DCTools:Analog Inputs >Smart AnalogsWeb: Input /Output > SmartAnalogsSmart AnalogAverageThe average value over the last Smart Analog loginterval.Smart AnalogMinThe minimum value over the last Smart Analog loginterval.
