2 Introduction
Congratulations on purchasing the GALAXY GX2 Automated Test System, the next generation
Test Stand and instrument management system from MSA. This system is used exclusively with
the ALTAIR® family of gas detectors. This manual uses the terms instrument and gas detector
to represent that entire line of ALTAIR gas detection instruments.
In this manual the user will learn to install and configure the GALAXY GX2 Test Stand and optional
attachments, and test gas detectors. Maintenance, Troubleshooting, and Technical Specifications
sections are also provided.
The Test Stand uses a sophisticated internal processor and simple to use touch screen display
for the configuration of calibration parameters and gas detector settings, and for gathering instru-
ment data.
Each Test Stand and optional attachments can be wall or desk mounted to serve the needs of the
user. Constructed of durable composite polymers, this equipment is designed for normal indoor
applications and operates within a broad temperature range of 0º to 40ºC in non-condensing hu-
midity atmospheres.
The principal components of the GALAXY GX2 include the Test Stand and optional electronic or
non-electronic Cylinder Holder, Multi-Unit Charger, and Receipt/ Sticker Printer. These compo-
nents [ Fig. 1] are designed to be attached (excluding the printer), to avoid accidental separation
during operation.

Introduction
GALAXY GX2 9
US
The Test Stand is a standalone unit that can accommodate one gas detector of the ALTAIR family.
However, each Test Stand contains the plumbing and electronic ports to simultaneously connect
a total of 10 Test Stands and four Cylinder Holders (electronic or non-electronic).
For applications where multiple Cylinder Holders are connected, the Test Stand Expanded Sole-
noid option must be ordered. This option allows the Test Stand to open and close up to four Cyl-
inder Holder valves for gas detectors that may require multiple cylinders for test purposes. For
example, an ALTAIR 5/5X with the standard 4 sensors plus a toxic sensor likely requires two gas
cylinders.
The electronic Cylinder Holder is designed to read a Radio Frequency Identification (RFID) tag
embedded in a plastic ring on MSA test gas cylinders. The RFID tag contains cylinder parameters
that are necessary for successful calibration operations, providing the customer with an excep-
tionally easy setup experience. Gas cylinder information is automatically populated without user
intervention when using the RFID-tagged gas cylinders.
If MSA test gas cylinders are not used, the non-electronic version of the Cylinder Holder is avail-
able. This configuration [ Fig. 2] requires the user to manually enter cylinder parameters.
Fig. 2 Non-electronic Cylinder Holder and Test Stand.
A USB port is provided on the Test Stand that may be used with the Digital Secure USB key to
change instrument settings via the touch screen. This function allows for convenient fleet
management capabilities. The port may also be used for an optional Receipt/ Sticker Printer, to
print calibration/bump stickers or paper receipts after an instrument test.
The primary functions of the Test Stand are to calibrate and bump the ALTAIR family of gas de-
tectors. For a detailed definition of these processes, please refer to:
http://www.safetyequipment.org/userfiles/File/calibration_statement-2010-Mar4.pdf
In the following sections of this manual the user will learn how to install the GALAXY GX2
Automated Test System, set up its functionality, and perform instrument tests. The hardware, soft-

ware, and configuration options anticipate the user's needs and provide superb efficiency in this
next generation Automated Test System.
GALAXY GX2 System Features and Options
The GALAXY GX2 automatically identifies the type of gas detector inserted into the Test Stand.
Based on user-defined settings, the Test Stand then performs bump tests and/or calibrates the
instrument. The data collected from each test event is stored to a memory card [ chapter 2.2]
and/or optional MSA Link™ Pro software application for data analysis (refer to the MSA Link Pro
end-user manual).
2.1 Power Supply
The Test Stand supplies power to the attached electronic Cylinder Holders. The Test Stand and
Multi-Unit charger are powered individually by one of the following methods:
-Power Module: Input power requirements: 100 - 240 VAC, 47 - 63 Hz
(Several different prong types are available for world-wide AC sockets).
-Optional Vehicle Module 12/24 VDC (For use in a cigarette lighter socket).
2.2 The Test Stand
The Test Stand performs the following functions:
-Bump or calibration testing per user setup.
-Records test results to the optional memory card and to an optional networked PC interface.
-Sends gas detector Instrument Periodic and/or Session datalogs to a networked PC interface.
-Provides optional instrument charging capability.
-USB key allows gas detector settings to be changed securely, with the touch of the Test Stand
screen.
-Permits printing of test results to an instrument sticker or receipt, with the optional Receipt/
Sticker Printer.
-Sends e-mail notification of system alerts per user setup.
An LED indicator shows the status of the Test Stand:
-Green light indicates that the Test Stand hardware and software are fully functional.
-Blinking green light indicates that the Test Stand is performing the user specified test or data-
log download.
-Blinking yellow light indicates that the Test Stand is in error and cannot be used for gas detec-
tor testing. Diagnostic information is available as described on the "GX2 Status" screen on the
Test Stand and in the Troubleshooting section of this manual [ chapter 6].
-Red light indicates that the last calibration or bump test failed.
NOTICE
Use of a power supply not specified by MSA will void the instrument warranty and could cause
damage to the GALAXY GX2.

Fig. 3 Test Stand Physical Features
SD or SDHC Memory Card Slot
A memory card port is provided on the Test Stand for calibration and bump record storage. An
SD or SDHC memory card can be purchased from MSA (preferred) or from the following manu-
facturers:
-Kingston
-PNY
-SanDisk
-Lexar
-Wintec
The data on an SD or SDHC memory card is encrypted for use with MSA Link™ or the
MSA Link Pro application. The type and amount of data recorded to the memory card is contin-
gent on whether the Test Stand is networked.
Test Stand Networked to a PC
When the Test Stand is networked to a PC through the Ethernet port, test records, datalogs, and
settings will be transmitted from the GALAXY GX2 to the PC interface.
If the network connection is lost only calibration and bump records are saved to the memory card.

Introduction MSA
US
Test Stand is Stand-Alone
If the GALAXY GX2 is not networked to a PC interface the memory card will save each calibration
and bump test record. Incomplete records will not be saved. If networked and e-mail alerts are
configured, the Test Stand will generate an email alert once the memory card reaches 90% and
again at 99% capacity.
Once a memory card reaches full capacity, the Test Stand will be in fault and prohibit any unit from
performing tests in that bank, until corrected. The Test Stand can be configured to erase the
memory card, or the user can insert a replacement.
An optional end cap [ Fig. 4] can be placed over the port to protect the memory card and all
external connections.

USB Drives
Two optional USB Keys [ Fig. 5] are available for purchase with the GALAXY GX2
Automated Test System:
-Digital Secure USB Key: This black key is inserted in the USB port on the Test Stand in order
to change gas detector settings. The key ensures only authorized users can change settings
on ALTAIR gas detectors; a security step in addition to the four-digit password.
-MSA Link Pro Key: This red key is used to enable the MSA Link Pro application on a single
PC. More information about this key can be found in the software product end-user manual.
Fig. 5 Digital Secure Key and MSA Link Pro Key
The memory card should only be removed when no test activity is occurring. Events that
occur while no memory card is installed will not be stored in the Test Stand.
If no memory card is used, only the most recent bump or calibration record is stored to
the Test Stand internal memory.

-Format #1: Calibration Sticker only (2 cm x 2 cm square label).
-Format #2; Receipt and Sticker combined.
Fig. 8 Optional Printer
2.7 Optional Multi-Unit Charger
There are two configurations of the optional Multi-Unit Charger (MUC). The ALTAIR 4/4X MUC
can simultaneously charge up to four ALTAIR 4/4X gas detectors. Similarly the ALTAIR 5/5X MUC
can charge four 5/5X gas detectors. Each Multi-Unit Charger contains its own power supply and
does not connect electrically to the Test Stand. The housing is designed to physically connect to
each other, whether bench-top or wall-mounted (if desired).
The light indicators on the Multi-Unit Charger are defined as follows:
-Red indicates that the unit is charging
-Green indicates that the unit is fully charged or no unit is inserted.
There can be as much as a 10 minute window between when the instrument battery indicator
shows charged and the Multi-Unit charger status indicator changes. The instrument indicator is
the most accurate and will indicate the true charge state of the battery.
DU
MM
Verify the Multi-Unit Charger indicator lights red when an instrument is inserted. A fully
charged instrument will momentarily flash red and the indicator will light green. If the red
light does not engage the instrument may not be seated properly on the charging prong.
Instruments whose battery is completely discharged will be need to trickle-charge
prior to normal charging operations. Such instruments will show a green LED during the
trickle-charge period until normal charging is initiated, at which time the red LED will be
active.

2.8 Special Conditions for Use with Reactive Gases
If using a Test Stand and Cylinder Holder for calibrating or bump testing a gas Detector config-
ured with a chlorine or ammonia sensor:
-Place the chlorine or ammonia gas cylinder in the Cylinder Holder closest to the Test Stand.
-Only one reactive gas Test Stand is allowed in a bank.
-If connecting other Test Stands to the right of the reactive stand, plug the reactive gas outlet
port with a white gas plug before mating the next Test Stand. Otherwise, inaccurate calibration
could result on the reactive sensor.
-Before the first use with reactive toxic gas, condition the regulator and Test Stand with the gas,
by running the calibration twice in sequence. If using chlorine, perform this procedure daily be-
fore use.
If not using GALAXY GX2 Cylinder Holders:
-Use a dedicated pressure regulator on the reactive toxic gas cylinder (for chlorine or ammonia,
use P/N 10034391). Label the pressure regulator "FOR CHLORINE USE ONLY" or
"FOR AMMONIA USE ONLY", as applicable (label stickers are provided with regulator).
-Use the shortest possible tubing running from the reactive toxic gas pressure regulator to the
Test Stand's "CYLINDER 1" port.
-Before the first use with reactive toxic gas, condition the regulator and Test Stand with the
gas by running the calibration twice sequentially; for chlorine, perform this procedure daily be-
fore use.
-Many gases have a cross-sensitivity to other gases. Ensure that test cylinder gases do not
contain other interfering gases.
Do not use the GALAXY GX2 to calibrate or bump a gas detector with a chlorine dioxide (ClO2)
sensor.

GX2 Gas Setup
The GALAXY GX2 Test Stand can accept test cylinder gas from the optional Cylinder Holders
(electronic and non-electronic) or from a user provided regulated gas source. Cylinder data can
be set for up to six gas types per cylinder. The following are the maximum number of gases each
instrument can process:
-ALTAIR and ALTAIR Pro: 1 gas
-ALTAIR 4/4X: 4 gases (typically 1 cylinder with quad gas)
-ALTAIR 5/5X: 5 gases (typically quad gas + 1 toxic gas)
-ALTAIR 5IR/5XIR: 6 gases
Datalogs are not written to the memory card because of potentially large file sizes. If the
unit is not networked to the MSA Link Pro software application, instrument datalogs
cannot be downloaded with the GALAXY GX2. In this situation the user can use the
MSA IR dongle and the free MSA Link application to download datalogs from the
instrument.
In order to effectively manage the time required to download datalogs, it is recommend-
ed that datalogs be downloaded and erased after each test. This will result in storage
of only the most recent information in the instrument datalog, minimizing time to
download the information.

The GALAXY GX2 processes gas cylinder information and instrument readings in ppm,
%(volume) or %LEL. If using certified gas cylinders with the content specified in ppm, the most
accurate gas readings from the instrument will be obtained with the instrument set to ppm.
Conversions between ppm and mg/m3 are completed at standard pressure and temperature val-
ues. If the gas detector is set to display the readings in mg/m3, note that differences in the follow-
ing environmental conditions will cause the readings to be affected:
-Standard temperature: 20 ºC (68 ºF)
-Standard pressure: 101 kPa (760 torr)
An instrument can be set up with Comb EX as its combustible gas. Comb EX is combustible gas
that is not in the GALAXY GX2 database and must be manually entered. Hexane is an example
of a Comb EX gas that can be used for calibration, but is not listed in the database. Not all com-
bustible gases can be used to calibrate the ALTAIR family of gas detectors. If the Comb EX se-
lection is used, contact MSA to confirm your selected combustible calibration gas is compatible
with the instrument and GALAXY GX2.
To access all functionality of the GALAXY GX2 cylinder configuration capabilities,
an electronic Cylinder Holder must be connected to the GALAXY GX2.

Reminder: Instrument datalogs can only be downloaded when an Ethernet connection to
MSA Link Pro is active or via an IR Dongle to MSA Link.
Helpful Hint: Instrument Periodic datalogs can grow large and create lengthy download times,
particularly for the ALTAIR 5/5X. MSA recommends downloading and then erasing Periodic data-
logs after every test. Erase Datalog is the default setting.
The GX2 will only erase instrument datalogs after receiving confirmation from MSA Link Pro that
data is successfully stored. If the software application is inactive the Test Stand displays a mes-
sage stating datalogs cannot be downloaded.
(7) The instrument Pass or Fail screen displays. This screen displays until a new instrument is
inserted or the user makes another selection on the touch screen. If datalog downloads are
enabled, the screen will indicate the status of the download (Successful or Failed) at the
completion of the data transfer.
If the instrument passes the test, remove it or select Home.
If the instrument fails the test, select Calibration Details or Bump Details for sensor failure
information.
If the instrument is removed while the Test Stand is performing a calibration or bump
the instrument will default to the last valid and retained calibration parameters. For gas
detectors with multiple sensors, any green colored calibration progress values are con-
sidered a valid calibration.

If a sensor failed during a bump, attempt to calibrate the instrument. Refer to calibrate an
instrument in this manual.
If the unit fails the calibration, review the troubleshooting section [ chapter 6] of this man-
ual.
If Cylinder is Configured Incorrectly or Gas is Not Available
The Test Stand will verify the instrument sensors are compatible with the gases in the cylinder(s).
If not, the GALAXY GX2 will:
(1) Prompt the user to run a partial bump or calibration.
(2) If a partial bump or calibration is acceptable, select Yes.
If not, select Home to navigate to the administrator screen.
ZIf a partial bump or calibration is performed the test results screen displays.
ZDashes (---) under the results column indicate unavailable gases for the test.
If the instrument fails the bump test while the mode is set to Bump/Cal on Fail the Test
Stand will automatically calibrate the instrument.
The Calibration Information screen displays two columns for the sensors: As Found and
Target. As Found is what the Test Stand detected prior to calibration. The Target col-
umn specifies the span gas value that is being applied. If the sensor passes calibration,
the Target value becomes the new calibration point.
If using the ALTAIR 4/4X or 5/5X the instrument will shut off if not removed from the Test
Stand within 5 minutes after test completion. If the GALAXY GX2 is equipped with the
charging option the instrument will begin charging after shutoff.

After Setup is complete:
After initial installation and setup are complete, confirm the GALAXY GX2 is properly configured.
Perform manual calibrations on several instruments and then repeat the calibration using the
GALAXY GX2. Confirm the calibration results are equivalent.
5.4 Classic Mode
If the Classic Mode button is enabled (3), every time a gas detector is inserted in the Test Stand
it will be tested according to the user-selected Mode. This feature ignores the Calibration and
Bump Interval.
Fig. 24 Test Setup
If the user disables the Classic Mode (2) and datalog downloading is enabled, the Test Stand will
determine if testing is due. If not, the Test Stand downloads the datalogs.
If performing a manual bump or calibration on an individual sensor in a multi-gas detec-
tor, always perform the manual test after the GALAXY GX2 test is complete.
If using MSA Link Pro software, partial bump tests will result in the instrument being list-
ed as "Overdue" for bump testing since not all sensors were tested.

5.5 GALAXY GX2 Always Ready Feature
The Always Ready feature is a capability of the ALTAIR 4X and ALTAIR 5X with the following
software versions:
-ALTAIR 4X: v2.03 and higher
-ALTAIR 5X: v1.11 and higher
The feature permits the gas detector to be automatically calibrated on a user-defined interval. The
most common use of this feature allows the user to configure the GALAXY GX2 to automatically
calibrate an instrument prior to the start of work-shift.
The following configurations must be set to allow the Always Ready feature to be active:
When these conditions are met, every hour the instrument will internally check its clock and last
calibration time and date. If the next calibration is due to occur within the hour, the gas detector
powers itself on and the Test Stand will initiate the calibration. Following calibration, the Test
Stand will power off the instrument and begin charging. The sequence repeats based on the
Calibration Due Interval.
Instrument GALAXY GX2 Test Stand
-Calibration Due Interval = any interval
[ chapter 4.6]. Ensure that this interval is
the same as on the Test Stand.
-Valid calibration at the desired time of day
-Charging version of the Test Stand
-Calibration Due Interval = any interval
[ chapter 4.6]. Ensure that this interval is
the same as on the gas detector.
-Test Mode = Calibration
The Always Ready feature is solely based on Calibration Due Interval, not on time of
day. Each subsequent calibration starts within the same hour of the day as the previous
calibration.
If for some reason the instrument fails calibration two times in a row, the Always Ready
feature will be disabled in the instrument to prevent calibration gas from being unnec-
essarily consumed. The user must diagnose the cause of the failed calibrations and in-
itiate a valid calibration at the desired time of day.

6 Troubleshooting
Use the following information to diagnose abnormal conditions.
6.1 Instrument Will Not Initiate a Bump or Calibration
(1) Ensure the instrument is turned on and errors are not displayed.
(2) If using an ALTAIR or ALTAIR Pro, press and hold the button for one second. The screen on
the gas detector must display Gas? prior to insertion into the Test Stand.
(3) Ensure the instrument is seated securely in the Test Stand cradle.
(4) If using the ALTAIR 5 or 5X, ensure the instrument pump inlet is seated securely in the
Test Stand gas inlet sleeve.
(5) Verify errors are not displayed from the electronic Cylinder Holder. If using the non-electronic
Cylinder Holder, ensure adequate connections are made and verify cylinder pressure.
(6) If using a GALAXY GX2 with the charging option for the ALTAIR 4/4X or 5/5X ensure the
charging connection fits securely to the instrument. This properly aligns the instrument in the
test stand.
(7) Ensure the GALAXY GX2 is set in the desired test mode. Refer to the GALAXY GX2
Configuration [ chapter 4.5] in the Setup section of this manual.

6.2 Instrument Fails Zero Calibration or Bump
(1) Check the Fresh Air filter and replace if contaminated.
(2) If not using zero gas, ensure that the atmosphere is free of any interfering gas.
(3) If connecting test gas without a Cylinder Holder, ensure the gas tubing line is not connected
to the top fresh air port on the left side of the farthest left unit.
6.3 Instrument Fails Span Calibration or Bump
(1) Verify the instrument span setting is the same value as the test gas.
(2) For ALTAIR H2S and ALTAIR CO instruments, ensure that the green gas seal is inserted in
the Test Stand.
(3) For ALTAIR 5/5X instruments, verify that the gas inlet on the instrument is fully inside the
inlet nozzle on the Test Stand.
(4) Check the right side of the farthest right unit to ensure the white plugs are secure over the
gas outlet connections.
(5) Check the sides of each unit to ensure the gas line barb fittings are in place and aligned
between the Test Stands and Cylinder Holders. Misaligned barbs lead to gas leakage.
(6) Ensure the cylinder configuration is correct. Refer to the Cylinder Configuration information
in the Setup section [ chapter 4.7] of this manual.
(7) Use the Details screen to identify failing sensor(s). If repeated failures occur, replace sensor
per instrument manual instructions.
6.4 Instrument Records Do Not Display
Instrument records only display in the farthest right Test Stand. Check the memory card port in
the right side port of the farthest right Test Stand. If the optional SD or SDHC memory card is not
installed, the instrument cal and bump records will not display.
Test Records Not Saved to Memory Card
Most likely caused by a corrupted memory card or new card that is write protected. In the case of
a write protected memory card, slide the switch on the side of the card to set it to accept data.
Occasionally, in normal use conditions, electrochemical sensors can be exposed to
either very high levels of the target gas or to an interferent gas, which can saturate the
sensor electrolyte or filter. If this type of saturation occurs, it may affect the sensors per-
formance and ability to zero or span calibrate. This is typically a temporary effect and
the sensor will self-recover if left in fresh air. The recovery time is dependent on the
saturation gas and the level of exposure, but is less than 24 hours in almost all cases.
Recovery should be attempted prior to sensor replacement.

7.3 Fresh Air Filter Replacement
The disposable fresh air filter is located on the tubing attached to the upper port on the left side of
the farthest left unit. The filter requires periodic replacement, based on the unit's frequency of use
and environmental cleanliness. Visual inspection of the fresh air filter will indicate contamination.
Replace as needed.
Fig. 25 Fresh air filter
To Replace the Filter:
(1) Remove the filter and tubing from the barb fitting in the fresh air port on the left side of the
farthest left unit.
(2) Dispose of the old filter.
(3) Insert the new filter and tube onto the same barb fitting of the fresh air port.
Pump Alarms may indicate the need to replace the fresh air filter.
NOTICE
Do not run the unit without the filter in place (even if using a zero-air cylinder in your installation);
otherwise, the valves and pumps may be damaged.
If the system consists of four or more Test Stands, use the high capacity filter and
ensure the flow arrow indicator points toward the unit.

7.4 O-Ring Seal Replacement (Cylinder Holder)
Each month, visually inspect the O-ring on the fitting and clean if necessary. Replace if any dam-
age is found.
(1) Remove the damaged O-ring.
(2) Clean the fitting with a water-dampened cloth and apply a light film of mineral oil to the new
O-ring.
(3) Place the new O-ring onto the fitting.
7.5 Inlet Seal Replacement (ALTAIR 5/5X Gas Detector)
Flow Errors and Calibration Failures may indicate a damaged inlet seal. MSA recommends annual
seal replacement.
Replace the seal:
(1) Remove the stainless steel eyelet (collar).
(2) The rubber inlet seal can now be removed from the fitting.
(3) Place the wider (flared) end of a new inlet seal over the fitting.
(4) Replace the stainless steel eyelet (collar) and ensure it is seated at the top.
NOTICE
Do not use a silicone-based lubricant on this O-ring.
