Sierra Monitor Corporation IZS31 operation manual Function description, Operation mode

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.

3-1. 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

Continuous static charge eliminating 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. 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	When maintenance start-up signal is input, or the power supply of the ionizer
operation	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.
