Sierra Monitor Corporation IZS31 ．DC mode, „ Connection with the power supply for I/O signal

4-3．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 50 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
	・[Plus ion discharge] or [minus ion discharge] can be selected.
	Ion polarity	Switch setting
	Plus ion discharge	8
	Minus ion discharge	9

4.Wiring of the power supply cable

・Connect dedicated power supply cables.

Power supply cable for I/O signal

Signal for starting/ stopping the discharge

（NPN spec）Operation will begin when it is connected with DC2（-）［Black］.

（PNP spec）Operation will begin when it is connected with DC2（+）［Red］.

○： Wires that are minimum required to operate the ionizer. △ ： Wires that are required to use the functions.

－ ： Wires that are not necessary with the sensing DC mode. These wires should not be short-circuited with other cables.

5.Air piping

・When the piping is only connected to one port, the other unused port should be plugged with the M-5P that is packaged together with the ionizer.
