AC output voltage fine-tuning
There are 3 AC output voltage adjustment knobs on the left side of the AC output selector switch. It is
possible to fine-tune the output voltage using these adjustment knobs. Make sure to operate the
adjustment knob that corresponds to the position of the AC output selector switch.
Ex.: If the switch is set to 4 kV output, operate the AC 4 kV output adjustment knob.
Output fine-tuning range (AC output adjustment knob)
AC 4 kV
3.5 to 4.2 kV
AC 5 kV
4.2 to 5.2 kV
AC 7 kV
6.0 to 7.2 kV
CAUTIONS
CAUTIONS
• Set to a suitable output voltage for each ionizer. The proper voltage for
each ionizer can be found in the instruction manual for that model.
Using the wrong voltage can lead to failure of both the unit and the
ionizer.
• Because output voltage adjustment is carried out while the unit is
energized, it is very dangerous. It should only be conducted by an
operator who has proficiency in handling of electric products, including
electric wire.
PROHIBITED
• You may open the top cover of this product in order to adjust the
adjustment knob, but do not manipulate anything other than the
aforementioned output selector switch or output adjustment knobs.
Doing so may lead to accidents or malfunction.
• The top cover is connected to the unit by a ground wire. Do not remove
or damage this ground wire.
• After making adjustments, be sure to put back the top cover. Do not use
the product without the top cover.
Anomaly Detection Circuit
For safety, the anomaly detection circuit automatically stops high voltage output when high voltage is
leaked to any part of the unit other than the electrode.
Anomaly detection external output
(C-contact relay output, 3-pin terminal)
This product includes contacts for use with external alarm devices such as error lamps, buzzers, etc.
when anomalies are detected. (Because they are zero-voltage, a separate power source is
required.)
There is a few hundred millisecond delay after the power switch is turned ON before the transformer
reaches its normal value. So please include a 1 second time lag in external circuits such as PLCs.
(Please include a 1 second time lag on the PLC side after the input power source is turned ON
during which anomalies are not detected.)
