Introduction
This manual describes how the GXA-17 (Large Glass Breeze Break with Ionizer) works and how to
get the most out of it in terms of performance. Read this manual thoroughly before using and keep itat hand for future reference.

1. Features□The Large Glass Breeze Break with Ionizer (GXA-17) can be installed on all GX-A/GF-Abalances.

□The GXA-17 can protect the balance from the effects of air drafts and will ensure more accurate
weighing results.

□

An anti-static treatment has been applied to the breeze break components to reduce weighing
error caused by static electricity.

□

A fanless ionizer (static eliminator), which causes no breeze, is built into the Large Glass Breeze
Break.

□The ionizer can eliminate static electricity from the weighing sample before weighing, reducing
error. (Static is eliminated by bipolar ions which are generated by direct-current coronadischarge.)□

The ionizer electrodes are designed to be removed for cleaning and replacement.

□

By attaching the external IR switch (included with breeze break) to the ionizer, you can start
static elimination without pressing any key.

□

Power is supplied from the balance to allow the ionizer to be operated without using an ACadapter.

□PRINT or RE-ZERO or the static elimination function of the ionizer can be operated by using theoptional foot switch (AX-SW137-PRINT or AX-SW137-REZERO).

Static electricity
In general, when the ambient humidity is less than 45%RH, nonconductors such as powders, paper,and plastics easily become charged with static electricity. The influence of static electricity may cause aweighing error of several milligrams. The ionizer neutralizes this electrical charge.

Step 8 Connect the option board and cable from the breeze
break. Install the weighing pan and pan support to thebalance.

Step 9 Connect the plug of the external IR (touchless) switch

Step 8to the jack on the option board panel. If inserted correctly the LED will light up.
Place the external IR switch in an appropriate placenear the balance.
(For right handed people, place the external IRsensoron the left side of the breeze break so thatit can be operated with the left hand.)

□Do not hold the balance by the glass breeze break whenmoving the balance. Hold the balance body when moving.

□To clean the area around the weighing pan, remove theglass breeze break in the reverse procedure as above.

1.3. How to Use
Note: Keep some space between electrodes and the weighing sample. (Placing the sample too
close to an electrode may cause the sample to become charged.)
Remove any obstacles between electrodes and the weighing sample.
Do not activate the ionizer with weighing sample on the weighing pan. (Static will not be fully
removed.)Do not touch the electrodes while the ionizer is active.
Step 1 Open the door of the breeze break and hold the sample above the weighing pan (center) toneutralize it. At this time, do not place the sample on the weighing pan. (The charge on thesample will not be sufficiently eliminated.)(Example uses GX-1603A)

Step 2 Move your hand close to the external IR (touchless) switch. The sensor can detectmotion from about 5 cm. When the IR switch responds, the ION mark on the balance’s display
and the ionizer’s LED light up and static elimination begins.

Step 3

Static elimination stops automatically after an interval has passed (set in function settings,
default: three seconds).
The buzzer will sound and the ionizer LED will turn off to signal the end of static elimination.
While the ionizer is active, hold the weighing sample until the ionizer LED turns off. (Failure todo so may result in the weighing sample not being sufficiently neutralized and cause weighingerrors.)

Note□

When the external IR switch is connected, the IR switch inside of the ionizer cannot be used.

□

When a balance with a minimum display of 0.001g or 0.0001g is used, the balance operates
using a minimum display of 0.01g while the ionizer is used. The balance automatically returns
to the previous weighing mode some time after neutralization is completed.

□While the ionizer is active, make sure that the weighing sample is neutralized until the ionizer
LED turns off. Failure to do so may result in the weighing sample not being sufficiently
neutralized and cause weighing errors.

□The neutralization interval (ionizer operating interval, default: three seconds) can be changed
using the balance’s function settings. (Refer to 2. Function Settings of the Balance)□If the IR switch is kept at on after static elimination is complete, the ionizer LED will blink toalert the user.

□When the static elimination interval is set to manual, the ionizer can only be controlled
externally (external IR switch or optional foot switch). Manual static elimation can be done up
to 10 minutes.

□When the external IR switch is not connected, the IR switch inside the breeze break can beused, but depending on the material of the sample it may not respond.
（We recommended using the external IR switch）□Do not perform static elimination, weighing or use the foot switch (AX-SW137-PRINT or
AX-SW137-REZERO) while the balance is outputting non-weighing data (GPL data, calculation
result data, statistical data, or data stored in memory).
Doing so may cause the balance to prevent the display from updating. If the balance display
does not update, reset the balance by unplugging and replugging the AC adapter.
For details about the balance data output (function settings), refer to the balance instruction
manual.

1.4. Controlling the Ionizer Externally
By using a foot switch (AX-SW137-PRINT or AX-SW137-REZERO), PRINT or RE-ZERO or the static
elimination function for the ionizer can be used.
□□

Connect the foot switch to the external input connector.
You can assign a key to an AX-SW137-PRINT or AX-SW137-REZERO foot switch (soldseparately) through the external input connector function Ex PRt or Ex R (depending on the footswitch model) in ionizer function (ion Fnc) balance settings.

□Press the foot switch while the ionizer is operating to stop neutralization.

2．Function Settings of the Balance
The function table stores parameters that specify how the balance operates and is used to monitor orupdate those parameters. Function settings can be used to configure the performance of the ionizer.
The parameters are stored in memory until overwritten even if the AC adapter is removed. The tablemenu consists of two layers as shown in the diagram below. The first layer is the Class and thesecond layer is the Item. Each item stores a Parameter. The last displayed parameter is in effect.
After the PRINT key is pressed, these updated parameters are applied to operations of thebalance.

In general, when using the ionizer for a long time, dust may stick to the electrodes, which decreases
static elimination performance. Clean them periodically to maintain performance.

□If the static elimination function does not work after the needles of the electrodes are cleaned, replace
both electrode units with new ones. This is generally caused by wear to the needles.
The standard life of an electrode unit is approximately 10,000 hours.
Step 1

Step 2

Replacing Electrode Units
Step 1 Turn the electrode units 45 degrees counterclockwise
to remove from the ionizer.
Step 2 Replace both electrode units with new ones.

Step 3 Turn the electrode units 45 degrees clockwise
