４．Selection and setting of equipment

4-１．Sensing DC mode

1.Selection of bar length

・Select the length applicable to work size base on static charge elimination area and static charge elimination characteristics.

2. Installation of body

・Keep the distance between the ionizer and charged objects within 200 to 2000mm. Although the ionizer can be mounted outside of this range, it may not operate properly depending on the operating conditions. Therefore, be sure to check if the ionizer will operate properly.

3. Installation of the sensor

・Install the feed back sensor. Keep the detecting hole towards the charged face.

・It should be mounted within a 10 to 50mm of installation height. Although the ionizer can be mounted outside of this range, it may not operate properly depending on the operating conditions. Therefore, be sure to check if the sensor will operate properly.

・When the ionizer and feed back sensor are connected, the mode is automatically shifted to the sensing DC mode.

4. Setting of the maintenance level selecting switch

・Set the level for detecting the dirt on the electrode needle.

・Select the level from H（High）, M（Middle） or L（Low）. The dirt on the electrode needle cannot be detected with other levels.

H（High） ・・・ The level that doesn’t affect the static charge eliminating time (Even a small amount of dirt can be detected).

M（Middle） ・・The level that can notify the maintenance just before the static charge elimination time becomes slow.

L（Low） ・・・ The level that the static charge elimination time becomes slower than the one in the initial state.

・The dirt detection is done when the maintenance start-up signal is input.

5. Setting of frequency selection switch

・This switch is used to switch the [energy-saving operation] and [continuous static charge eliminating operation].

・With [continuous static charge eliminating operation], the ion-production frequency needs to be selected after the static charge elimination is completed.
