1. Introduction
This manual describes options for the GX-A series and GF-A series and how to get the mostout of them in terms of performance. Read this manual thoroughly before using the options andkeep it at hand for future reference.

2. Features
The following options can be used for the GX-A series and GF-A series.
GXA-03
GXA-04GXA-06Isolated RS-232C interface
Comparator output (with buzzer) / External contact input x 2
Analog voltage output

GXA-03: Isolated RS-232C interface
Commands from the PLC or other devices installed in the factory environment can be used tomake the following operations : output measurement data from the balance, input parameters
into the balance, control the balance, reference parameters of the balance, etc.
The RS-232C is equipped with a data format to manage the balance in accordance with GLP.
( Refer to the instruction manual of the balance. )GXA-04: Comparator output / External contact input
The GXA-04 can compare the weighing value and preset threshold values and can output theresult to the contact output.
The GXA-04 is equipped with six contact outputs: "HH", "HI", "OK", "LO", "LL" of thecomparison output and "READY" output to indicate the status of the balance.
3-stage comparison or 5-stage comparison can be selected.
The GXA-04 can sound a buzzer according to the comparison result.
The GXA-04 is equipped with external control input terminals that can make the RE-ZEROand PRINT key operations. An optional foot switch (AX-SW137-PRINT, AX-SW137-REZERO ) can be used.

GXA-06: Analog voltage output
The GXA-06 can output analog voltage in the following modes :"mode where the specified digits of the weighing value are converted to voltage" and"mode where weighing value is converted to voltage in range between gross zero or net zeroand full scale".
The voltage output range can be selected using the "0V /0.2V " switch on the panel.
It can be selected "0 to 1V" range and "0.2V to 1V" range. The factory setting is "0 to 1V" range.

5. Function Table of Balance
The function table stores parameters that specify how to operate the balance, and it is used tomointor or update those parameters. These parameters are stored in memory even if the AC
adaptor is removed and are retained until overwritten. Balance operations are specified by thistable when using the GXA-03, GXA-04 and GXA-06. The table menu consists of two layers
as shown in the diagram below. The first layer is the “Class” and the second 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 the balance.

7. GXA-04 Comparator Output
The comparator output (GXA-04) has the function to compare between the weighing value andpreset second upper limit, upper limit, lower limit or second lower limit. The result of comparison
can be output to the contact. When the contact is shorted, this option can select whether or not tosound the buzzer.
Optional foot switch ( AX-SW137-PRINT, AX-SW137-RE-ZERO ) or other external switches
can be used.

When 1 pin and 3 pin or 1 pin and 2 pin of lead wire of optional foot switch ( AX-SW137PRINT, AX-SW137-RE-ZERO ) is shorted 100 ms or longer, it can be operated the same as
the PRINT key and RE-ZERO key on the panel.

7.2.

Using the Comparator Output

This option can output results of the 3-stage comparison or 5-stage comparison that is
specified at "Comparison method ()" in the function table of the balance.
Comparison results are displayed using HI , OK , LO and are output using contacts ofI/O terminals. Comparison tolerance ranges are the following 3 types and they can be specified
at "Comparator mode ()" in the function table.
"No comparison", "Comparison when stable value or overloaded", or "Comparison always"
The range of near zero can is specified at "Near zero ()" in the function table.
There are two types of comparison method. One is the method using second upper limit, upper
limit, lower limit and second lower limit. Another is the method using center value and tolerance
range. There two types of input methods for second upper limit, upper limit, lower limit andsecond lower limit. One is the numerical input. Another is the input using sample weight.
Balance can sound a buzzer according to the comparison result. That can be specified at"Comparator buzzer ()" in the function table.
When weighing value is not displayed in performing RE-ZERO, etc., READY contact
becomes "open". When weighing value is displayed, READY contact becomes "short".

Voltage Output Fine Adjustment

The voltage output has been adjusted at thefactory before shipment.
Using the ZERO volume and SPAN for fineadjustment and a voltmeter, voltage output canbe finely adjusted.

Procedure
Step 1 Turn off the display using the ON:OFF key.
Voltage output becomes zero point status.
Adjust the ZERO volume so that the voltmeter indicates
0.000 V ( when the slide switch is set to "0V ").
Adjust the ZERO volume so that the voltmeter indicates
0.200 V ( when the slide switch is set to "0.2V ").

The display to output 0 V ( 0.2 V).

Step 2 While pressing and holding the PRINT and
SAMPLE keys, press the ON:OFF key to enter the
initializing mode. Then 1 V is output. Adjust the SPAN
volume so that the voltmeter indicates 1.000 V

The display to output 1 V.

Step 3 Repeat step 1 and step 2 until the correct voltage output isobtained.

Fixed Voltage Output

The voltage output is fixed under the following conditions:With the display off, 0 V is output ( or 0.2 V if the slide switch is set to "0.2V ") when notweighing during calibration, etc..
During the re-zeroing operation in gross full scale output mode (the previous output value is retained.

),

During the re-zeroing operation in 2-digit output mode (0 V is output ( or 0.2 V if the slide switch is set to "0.2V ").

),During the re-zeroing operation in 3-digit output mode (0 V is output ( or 0.2 V if the slide switch is set to "0.2V ").

),During the re-zeroing operation in Net full scale output mode (),

0 V is output ( or 0.2 V if the slide switch is set to "0.2V ").
When -E (weighing value is negative overload) is displayed,
0 V is output ( or 0.2 V if the slide switch is set to "0.2V ").
When E (weighing value is positive overload) is displayed,
the following voltages are output.
Example Voltage output when E is displayed if the slide switch is set to "0V ".
