SPVNZBAT activates the start and alarm outputs when the battery terminal voltageexceeds the set upper limit or drops below the set lower limit. A time delay for theovervoltage and undervoltage alarms can be set according to definite timecharacteristics.SPVNZBAT operates after a settable operate time and resets when the batteryundervoltage or overvoltage condition disappears after settable reset time.14.14.4 SignalsTable 396:SPVNZBAT Input signalsName Type Default DescriptionU_BATT REAL 0.00 Battery terminal voltage that has to be supervisedBLOCK BOOLEAN 0 Blocks all the output signals of the functionTable 397:SPVNZBAT Output signalsName Type DescriptionAL_ULOW BOOLEAN Alarm when voltage has been below low limit for aset timeAL_UHI BOOLEAN Alarm when voltage has exceeded high limit for aset timeST_ULOW BOOLEAN Start signal when battery voltage drops belowlower limitST_UHI BOOLEAN Start signal when battery voltage exceeds upperlimit14.14.5 SettingsTable 398:SPVNZBAT Non group settings (basic)Name Values (Range) Unit Step Default DescriptionOperation OffOn- - On Operation mode Off / OnRtdBattVolt 20.00 - 250.00 V 1.00 110.00 Battery rated voltageBattVoltLowLim 60 - 140 %Ubat 1 70 Lower limit for the battery terminal voltageBattVoltHiLim 60 - 140 %Ubat 1 120 Upper limit for the battery terminal voltagetDelay 0.000 - 60.000 s 0.001 0.200 Delay time for alarmtReset 0.000 - 60.000 s 0.001 0.000 Time delay for reset of alarmSection 14 1MRK 504 135-UEN AMonitoring490Technical manual
