5. Functional Explanation
1. Detection of dirt on electrode needle
During operation reduced charge elimination capability due to a dirt or wear on electrode needles is
monitored continuously. If it becomes necessary to clean the electrode needle, the LED for maintenance
lights up on the display of the product and maintenance output signal is generated.
2. Input of external switch signal
There are two ports for external switch signal inputs.
If a pressure switch or electrostatic sensor is connected, discharge can be stopped for abnormal pressure
or completion of charge elimination.
3. Name of indication LEDs.
Name Indication Color Content
Power supply PWR Green Lights up when the power supply is turned on.
Discharge ION Green Lights up when discharge is performed.
High voltage error HV Red Lights up when excessive current flows to the electrode needle.
Maintenance NDL Orange Lights up when a dirt or wear on the electrode needle is detected.

4. Content of alarm
Description Content How to reset
High voltage error Informs that abnormal current such as high
voltage leakage has occurred. “HV” LED
lights up and ion emission is stopped.
The error signal is turned off when error
occurs.
Turn off the power supply, solve the
error and restart the power supply.
If the error is solved correctly, turn the
reset signal on and off.
Electrode needle
maintenance
period
Informs that maintenance of electrode
needles is necessary. “NDL” LED lights up
and maintenance signal is outputted.
Turn off the power supply, clean the
electrode needle, and then restart the
power supply.
