Charged potential of the
work is output with
analog signal (1 to 5V)
※ Be sure to ground DC1(-)［Blue］. (Resistance between the lead wire and the earth ground should be 100Ω or less.)
If not, it may break the ionizer.

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］.
IN2 Gray Maintenance start-up signal
△
A signal that is input when the maintenance of the
electrode needle is necessary.

－ Orange － － －
OUT1 Pink Completion signal for
static charge elimination
△
Outputs when the charged potential of the work is +/-30V
or more, and when the dirt on the electrode needle is
detected.
OUT2 Yellow Maintenance output signal
△
Outputs when the maintenance of the electrode needle is
necessary.
OUT3 Purple Signal for failure
△
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.
