Introduction
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
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 settin gs, and for gath ering instrument 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 humidity atmospheres.
The principal components of the GALAXY GX2 System include the Test Stand and optional electronic or non-electronic Cylinder Holder, Multi-Unit Charger, and Receipt/ Sticker Printer. These
components [ Fig. 1] are designed to be attached (excluding the printer), to avoid accidental
separation during operation.

Introduction
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 simultaneo usly 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 a nd clo se up to fo ur Cylinder 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 exceptionally 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 available. 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 GALAXY GX2 USB key to
change instrument settings via the touch scree n. 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 detectors.
A Bump Test (or Function Check) is a qualitative check conducted by applying a known challe nge
gas to the instrument. The purpose of this check is to confirm sensor functionality and to verify the
integrity of the flow path to the sensor(s). Perform a bump test prior to each day's use.
US
GALAXY GX2 Automated Test System

Introduction
A successful calibration consists of the adjustment of the sensor('s) output to match the precise
concentration value of a known traceable calibration cylinder. A calibration can be performed at
any time to ensure maximum accuracy. A calib ration should be performed periodically at regular
intervals and immediately if the unit fails a bump test.
See the instrument manual for specific conditions that require a more frequent bump or calibr ation
interval. Also see the instrument manual for information on ch ecking the gas detector alarm functions.
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, software, 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 System automatically identifies the type of gas detector inserted into the Test
Stand. Based on user-defined settings, the Test Stand then per forms 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).
MSA
2.1 Power Supply
The Test Stand supplies power to the attached electronic Cylinder Holders. The Test Stand and
Multi-Unit charger are powered indivi dually 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).
NOTICE
Use of a power supply not specified by MSA will void the instrument warranty and could cause
damage to the GALAXY GX2 System.
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 da talogs to a networked PC inte rface.

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 manufacturers:
- Kingston
- SanDisk
- Lexar
- Wintec
The data on an SD or SDHC memory card is encrypted for use with MSA Link™ Pro application.
There is also an application available on the MSA website to create a printable version of the SD
card records (MSA GALAXY GX2 SD Card Reader.exe).The type and amount of data recorded
to the memory card is contingent on whether the Test Stand is networked.
Test Stand Networked to a PC
If the network connection is lost, only calibration and bump r ecords are saved to the memory card.
If networked and e-mail alerts are configured with MSA Link Pro, the Test Stand will generate an
email alert once the memory card reaches 90% and again at 99% capacity.

Introduction
Test Stand is Stand-Alone
If the GALAXY GX2 Test Stand is not networked to MSA Link Pro, the memory card will save each
calibration and bump test record. Incomplete records will not be saved.
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.
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.
An optional end cap [ Fig. 4] can be placed over the port to protect the memory card and all
external connections.

MSA AUER
MSA
Introduction
Multi-Color Light Band
Indicates gas bottle functionality.
- Green indicates a bottle is
completely functional, and gas
parameters are within pressure
and expiration date limits.
- Yellow indicates low calibration
gas, or gas is nearing its expiration date.
- A blinking yellow light band indi-
cates a hardware problem with
the cylinder holder.
- Red indicates an empty calibra-
tion gas bottle, or that gas has
expired.
RFID Tag Gas
Identification
Reads the RFID tag of
the MSA test gas cylinder and transmits:
- the gas type
- gas concentration
- expiration date
- lot number
- cylinder part number
to the Test Stand. The
RFID tag is only available on MSA-branded test
gas cylinders shown in
the Maintenance section
[ chapter 7].
Pressure Regulator & Sensor
Reads the pressure of the gas
cylinder and transmits that
information to the Test Stand.
- When gas pressure drops to
approximately 99 psi
(6.89 bar) a warning will
display and the display
numbers appear yellow.
- Once pressure drops to ap-
proximately 49 psi (3.45 bar)
the display numbers appear
red.
- Once pressure drops to less
than 5 psi (0.34 bar) the
Test Stand will prohibit testing with that cylinder.
2.6 Optional Printer
The Printer can print calibration and bump result receipts and calibrations stickers for gas detectors [ Fig. 7]. The Receipt/ Sticker Printer uses a USB cable to connect to the port of the farthest
right Test Stand [ Fig. 3].
Labels are available in two formats [ chapter 7.2]:
- 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
US
GALAXY GX2 Automated Test System

Introduction
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.
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 need to be 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 wil l be
active.
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.

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 configured with a chlorine or ammonia sensor:
16
GALAXY GX2 Automated Test System
US
MSA AUER
MSA
Introduction
- Place the chlorine or ammonia gas cylinder in the Cylinder Ho lde r clo ses t to th e Test Sta nd .
- 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 before 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 pro cedure daily before use.
- Many gases have a cross-sensitivity to other gases. Ens ure that test cylinder gases do not
contain other interfering gases.
The GALAXY GX2 System does not support the calibration or bump testing of chlorine dioxide
(ClO
) sensors due to the reactive nature of the gas. Manual calibration of ClO2 sensors is rec-
2
ommended using a very short tubing length.

3.2 Connect a Test Gas Source Without a Cylinder Holder
If high-pressure, high-capacity test gas cylinders are preferred, an optional demand regulator
(p\n 710289) is available for cylinders with pressure less than (<) 30 00 p si. Testing fr om an inde pendent gas source will require additional setup effort, as described in the Cylinder Configuration
section [ chapter 4.7].
(1) On the left-hand side of the Test Stand, en sure all five bar b fittings are in place and str aight-
ened.
(2) Place the user-supplied regulator onto the gas cylinder and secure a length of tubing onto its
outlet.
(3) Securely fit the end of the tubing over the appropriate barb fitting on the GALAXY GX2
Cylinder Holder.
3.3 Network Test Stands
Test Stands that are banked together should be connected through the provided Ethernet cab le.
The Master Test Stand is the one located on the furthest right of the bank.
(1) Insert the short Ethernet cable into the left side jack of each Test Stan d (1) and co nnect it to
the right side jack of the neighboring unit (2) [ Fig. 11].
One interconnect Ethernet cable is included with each Test Stand.
