Description

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 charged potential of the work is +/-30V or more, and 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 sensing 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.
