2. Connect the lead wires in accordance with the lead wire list. (See
Chapter 4) Arrange lead wires in accordance with the wiring table. The
unused wires should be cut short or covered with vinyl tape without
pealing the coat to prevent them from coming contact with other wires.
3. When the feed back sensor or auto balance sensor is used, remove
the dust cover from the modular jack with [signal] indication, and insert
the modular plug of the sensor cable (IZS31-CS). A lever will snap
when the modular plug is correctly locked. Fix cables with a tie wrap or
other measures in the vicinity of their connection not to apply
compulsive force to the modular jack and plug.
3. Function description
3-1. Operation mode
3 types of operation modes are available with IZS31 (sensing DC mode, pulse DC mode and DC mode.)
These modes are selectable depending on the applications and operating conditions.
1. Sensing DC mode
This mode detects the charged condition of the workpiece with the feed back sensor, and feed back the
condition to the ionizer. With this mode, ions with optimal polarity are discharged to shorten the static
charge elimination time. When the static charged of the workpiece becomes +/-30V or less
note)
, the
completion signal of the static charge elimination will turn off.
This mode is suitable for the object that is largely charged.
Once the static charge elimination is completed, [energy-saving operation] or [continuous static charge
elimination mode] can be selected.
Energy-saving
operation The ion-discharge output will automatically stop once the static charge
elimination is completed. If the charged potential of the work becomes +/- 30 V
or more, the ion will be discharged again.
The [energy-saving operation] is recommended for conductive workpieces.
Continuous
static charge
eliminating
operation The static charge will be continuously eliminated with pulse DC as maintaining
the ion balance to make the charged potential +/-30V or less
note)
even after the
static charge is completed.
The [continuous static charge eliminating operation] is recommended for
nonconductive workpieces.
Note) when the installation height of the feed back sensor is 25mm.
2. Pulse DC mode
The ionizer discharges plus ions and minus ions by turns.
When the auto balance sensor is used, the ion balance is automatically adjusted within +/-30V. If the ion
balance exceeds +/-30V due to the dirt on the electrode needle, the maintenance output signal will be
output.
This mode is suitable for eliminating the static charge in the air and/or on the workpieces.
„ When the auto balance sensor is used.
[Manual operation] or [auto operation] can be selected for the ion balance adjustment.
Manual
operation When maintenance start-up signal is input, or the power supply of the ionizer
Is applied, the ion balance adjustment will begin.
When workpieces are moving, [manual operation] is recommended. Start the
equipment after ion balance is adjusted.
Auto operation The ion balance is continuously adjusted.
When the static charge of the still workpieces or in the atmosphere is
eliminated, the [auto operation] is recommended.
„ When the auto balance sensor is not used.
The ion balance is adjusted with a balance adjusting trimmer. An instrument is separately needed to
check the ion balance.
