Sierra Monitor Corporation IZS31 operation manual Detection of the dirt on the electrode needle

3.DC mode

Plasma ions or minus ions are continuously discharged. The parts other than the charged object need to be grounded to prevent them from being charged. The plasma and minus ions cannot be discharged simultaneously.

3-2. Detection of the dirt on the electrode needle

When the maintenance start-up signal is input, the ionizer detects if the static charge elimination capability is degraded due to the dirt on the electrode needle. If the electrode needle needs to be cleaned because of the degraded capability of the static charge, the maintenance LED lights up, and then the maintenance output signal is output. Because just installing the feed back sensor or auto balance sensor is not enough to detect if the static charge eliminating capability is degraded, regularly input the maintenance start-up signal to check the static charge elimination capability.
