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.
Inthismanualthe user will learn to installandconfiguretheGALAXYGX2 Test Stand and optional
attachments,andtest gasdetectors.Maintenance,Troubleshooting,and TechnicalSpecifications
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]aredesignedtobeattached(excludingtheprinter),toavoidaccidentalseparation

Introduction
GALAXY GX2 9
US
TheTest Standisastandaloneunitthat can accommodateone gas detectorofthe 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

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 thetouch 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.

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.

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 faultand 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 cardshould only be removedwhen no test activityisoccurring. Eventsthat
occur while no memory card is installed will not be stored in the Test Stand.

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.
