Description Symbol Power supply display Discharge Irregular high voltage display Maintenance display PWR ION HV NDL Color Green Green Red Orange Contents Lights up when the power supply is turned on. Lights up when static electricity is discharged. Lights up when an irregular current flows on an electrode needle. Lights up when electrode needle contamination is detected. Items PWR Normal operation (with discharge stop signal on) Normal operation (with discharge stop signal off) Abnormal high voltage detected External switch signal 1 External switch signal 2 Electrode needle contamination detected Behavior of LEDs �ｷ �ｷ �ｷ �ｷ �ｷ �ｷ ION �ｷ �ｷ HV �ｷ NDL �ｷ Note Ions are being generated. Discharge stops. Discharge stops when error is detected. Discharge stops when the signal is turned on. Ions keep being generated even after the contamination is detected. Alarm item Description Corrective actions High voltage error Maintenance electrode needle 4. Alarm Gives notification of the occurrence of an irregular current, such as high-voltage leakage. The ionizer stops discharging, turns on the HV LED. When error occurred, the signal output is turned off. Turn off the power, solve the problem, then turn the power on again. If the error is solved during operation, turn the reset signal off and then on. Gives notification that electrode needle maintenance is necessary. The NDL LED turns on and a maintenance output signal is turned on. Turn off the power, clean the electrode needles, and turn the power on again. Abnormal pressure Stop occurrence Abnormal pressure detection Pressure switch Ionizer Charged potential measurement potential Static neutralization completed lectricity Electrostatic sensor monitor Ionizer Stop PWR ION HV NDL Functions 1. Electrode needle contamination detection Detects lowered static neutralization performance due to contamination or wear of the electrode needle. The maintenance LED lights up and maintenance signal is generated. 2. Signal inputs by external switch There are 2 ports for external switch signal inputs. Example Emission of static electricity is suspended when abnormal purge air pressure is detected by pressure switch. . Prevents static neutralization trouble due to pressure drop of compressed air. An electrostatic meter is connected to stop discharge when static neutralization is completed. . Energy can be saved by stopping discharge when static neutralization is completed. Example 3.
