1. Introduction
This manual describes options for the GX-A series and GF-A series and how to get the most
out of them in terms of performance. Read this manual thoroughly before using the options
and keep 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 Isolated RS-232C interface
GXA-04 Comparator output (with buzzer) / External contact input x 2
GXA-06 Analog voltage output
GXA-03: Isolated RS-232C interface
Commands from the PLC or other devices installed in the factory environment can be used to
make 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
the result to the contact output.
The GXA-04 is equipped with six contact outputs: "HH", "HI", "OK", "LO", "LL" of the
comparison 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-ZERO
and PRINT key operations. An optional foot switch (AX-SW137-PRINT,
AX-SW137-RE-ZERO ) 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 zero
and 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 to
mointor 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
this table 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
and preset 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 to sound the buzzer.
Optional foot switch ( AX-SW137-PRINT, AX-SW137-RE-ZERO ) or other external switches
can be used.

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 (
Comparison results are displayed using HI , OK , LO and are output using contacts of
I/O terminals. Comparison tolerance ranges are the following 3 types and they can be
specified at "Comparator mode (
"No comparison", "Comparison when stable value or overloaded", or "Comparison always"
The range of near zero can is specified at "Near zero (
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 and second 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 (

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

volume so that the voltmeter indicates 1.000 V
Step
3 Repeat step 1 and step 2 until the correct voltage output
is obtained.

8.5. 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 not
weighing 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.
