Determining the Model and Settings 1 / Sensing DC Mode
6) Wiring of power supply cable
· Connect the dedicated power supply cable.
7) Air piping
· For single-side piping, block the unused port with the M-5P plug supplied with the ionizer.

DC1 (–) [Blue] is sure to ground it according to class-D. If the terminal is not grounded, the ionizer may malfunction.
: Minimum wiring requirement for ionizer operation
: Wiring necessary to use various functions
—: Wiring not required in the sensing DC mode. Exercise caution to ensure that this wire does not short-circuit to other wires.
Outputs the workpiece’s electrostatic
potential as an analogue signal (1 to 5 V).

Input/output signal power supply cable
Signal to be input when determining the necessity of electrode needle maintenance
Signal to be output when the workpiece’s electrostatic potential is outside ±30 V or
when electrode needle contamination is being detected.
Signal to be output when electrode needle maintenance is necessary.
Outputs signal when there is irregular high voltage, irregular sensor, irregular CPU (B type contact output)
Signal for enabling/disabling discharging
(NPN specification) Discharging is enabled when connected to DC2 (–) [Black].
(PNP specification) Discharging is enabled when connected to DC2 (+) [Red].
