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.
