Series IZS31

Ionizer Series IZS31Determining the Model and Settings 2 / Pulse DC Mode9) AlarmAlarm item Description Corrective actionsHigh voltage irregularityGives notification of the occurrence of an abnormal current, suchas high-voltage leakage. The ionizer stops discharging, turns onthe HV ALARM display, and turns OFF the fault signal (OUT3).Turn OFF the power, solve the problem, then turn the poweron again. Alternatively, turn the discharge stop signal OFF,then ON.Sensor irregularityCPU irregularityElectrode needlemaintenanceGives notification that the feedback sensor has becomeunable to operate normally. The ionizer turns on the SNSRALARM display and turns OFF the fault signal (OUT3).Gives notification of the occurrence of a failure in the CPUdue to noise, etc. All of the LED displays blink and a faultsignal (OUT3) is turned OFF.Gives notification that electrode needle maintenance isnecessary. The NDL CHECK ALARM display comes on anda maintenance output signal (OUT2) is ON.Turn OFF the power, solve the problem, then turn the poweron again. Alternatively, turn the discharge stop signal OFF,then ON.Turn OFF the power, solve the problem, then turn the poweron again. Alternatively, turn the discharge stop signal OFF,then ON.Turn OFF the power, clean the electrode needles, and turnthe power on again.10) Timing chart Timing chart in normal operationPower supply24 VDCElectricity dischargestop signalState ofemitting ionsInputInputONOFFONOFFONOFF(Operation permission)(Emission) Timing chart in electrode needle stain is detected or ion balance is detected.(a) When an auto-balance sensor is connected.(1) Manual run(2) Auto runPower supply24 VDCElectricity dischargestop signal (IN1)Electricity removalInputInputOutputcompletion signal (OUT1)MaintenanceInputstart signal (IN2)Maintenance outputOutputsignal (OUT2)Maintenance displayLED(NDL CHECK ALARM)InternalprocessingONOFFONOFFONOFFONOFFONOFFONOFFStain-detectionIon balance adjustment(Operation permitted)(Electrode needle stain-detection or ion balance adjustment in progress)2 s(SW ON)(SW ON)(Display)Over 100 msBlinking(Performed when the maintenance levelselection switch is set to H, M or L)Power supply24 VDCElectricity dischargestop signal (IN1)Electricity removalInternalprocessingInputInputOutputcompletion signal (OUT1)MaintenanceInputstart signal (IN2)Maintenance outputOutputsignal (OUT2)Maintenance displayLED(NDL CHECK ALARM)ONOFFONOFFONOFFONOFFONOFFONOFFStain-detectionIon balance adjustment(Operation permitted)(Electrode needle stain-detection in progress)2 s(SW ON)(SW ON)(Display)Over 100 msBlinking(Performed when the maintenance levelselection switch is set to H, M or L)(b) When an auto-balance sensor is not connected.Power supply24 VDCElectricity dischargestop signal (IN1)Electricity removalInputInputOutputcompletion signal (OUT1)MaintenanceInputstart signal (IN2)Maintenance outputOutputsignal (OUT2)Maintenance displayLED(NDL CHECK ALARM)InternalprocessingStain-detectionIon balance adjustmentONOFFON(Operation permitted)OFF(Electrode needle stain-detection in progress)ON2 sOFFON (SW ON) Over 100 msOFFON (SW ON)OFFON (Display)BlinkingOFF(Performed when the maintenance levelselection switch is set to H, M or L): Either ON or OFF depending on the situation.· A signal indicating static electricity removal completion is output when the detection of electrode needle stain is in progress.IZSIZDIZEIZHCautionIons are emitted from the ionizer to detect electrode needle stain and the workpiece may therefore be electrostatically charged. Perform thisdetection procedure in the absence of workpieces.1071
