Function

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］.

A signal that is input when the maintenance of the electrode needle is necessary.

－

－

Outputs when the dirt on the electrode needle is detected.

Outputs when the maintenance of the electrode needle is necessary.

Outputs in case of abnormal high voltage and sensor and/or CPU failure.

(B contact output)

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

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

7.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.
