Alarm function
If abnormal functioning occurs during operation, the user is alerted by the LED operation.
Note that ion generation may continue or stop depending on the type of abnormality.

When static neutralization

contamination, wearing or breakage
of emitters.
-
1) Power supply failure
- When the power supply connected to the product is not within the range of 24VDC +/-10%, the PWR
LED (green) will flash to indicate the error.
- When the failure occurs, ion generation will be stopped.
- To resolve the abnormality, make sure that the power supply voltage is 24VDC +/-10%, and then turn
the power back on.
2) Incorrect high voltage
- If the high-voltage output drops during operation, ION/HV LED (red) turns ON to notify the error.
- When the failure occurs, ion generation will be stopped.
- The decrease of high-voltage output could be caused by abnormal discharge due to condensation or
dust on the emitters.
- In order to clear the alarm, remedy the cause of the abnormality, and supply power again.
3) CPU error
- When the CPU malfunctions due to noise, etc., the PWR (green), ION/HV (red), and NDL (green)
LEDs will flash to notify the error.
- When the failure occurs, ion generation will be stopped.
- To resolve the error, supply power again after fixing the cause of the error.
- To prevent noise, perform the following actions and take countermeasures.
1. Keep the product apart from the noise source.
2. Route the power line and cable of the product separately.
3. Install a noise filter to the power supply of the product.
4) Emitter maintenance indicator
- The maintenance signal is ON when static neutralization performance is decreased due to
contamination, wear or damage of the emitters. The NDL LED (green) will turn ON to indicate that
cleaning of the emitters or replacement needs to be performed.
- Ion generation continues even when the maintenance indicator LED is ON.
- If the emitter is worn or damaged, an alarm may be output continuously. In this case, replace the
emitter assembly (IZG10-NT).
