Part 2: Adjustment and Operation, Measured variable chlorine dioxide

Complete Operating Menu / DescriptionMeasured Value Control PeriodIMPORTANTThis function may not be activated for applications in which it can be assumed that themeasured value will not change.This function tests whether the measured value changes from that of the probe (at the measured valueinput) within the “Measured value control period”. It is assumed that it will do so for an intact probe.If the measured value does not change within this control period the DULCOMETER ® D1C sets the controlvalue to “0” and the alarm relay circuit is opened. The LCD displays the message, e.g. “check CIO 2probe”.Correction ValuePossible valuesInitial value Increment Lower value Upper value RemarksStandard signal input 4 mA 0 mAlower signal limit4 mAAllocated measuredvalue lower 0 ppmupper 2 ppm 0.01 ppm 0.00 ppm 20.00 ppmCheckout time off 1 s 1 s 9999 s Constant measurement signalresults in message and alarm.Function off = 0 sAccess to all setting menus can be blocked with an access code !only with correction valuecorrection valuesetting ?correction valuetemperaturemanual30.0 °Ccorrection valueα = 2.75 % / °CD1C2-ClO2-031-GBPumpsPossible valuesInitial value Increment Lower value Upper value RemarksType of temperature as per manual Switching only whencompensation identity code automatic identity codeoffshows = automaticManual temperature 25 °C 0.1 °C 0 °C 100 °CcompensationCorrection value α 2.75 %/°C 0.01 %/°C 0.00 %/°C 10.00 %/°CAccess to all setting menus can be blocked with an access code !pumpssetting ?Only with pumps for controlcontrolpump 1 ClO 2pump 2 De-ClO 2dosing pump max.pump 1: 180pump 2: 180pulse/minuteD1C2-ClO2-022-GB15
