Introduction

This section briefl y describes the S DM-2012 D ocking S t ation, the Single Modul e Data Viewer Program, and the SDM-GX Docking Station PC Controller Program. This section also describes the SDM-2012 Docking Station PC Controlled Configuration Operator’s Manual (this document). Table 1 at the end of this section lists the SDM2012’s specifications.

The SDM-2012 Docking Station is an advanced, reliable system that provides charging, calibratio n, bump test in g, and cali brati on and bu mp test r ecords for the GX2012 and Gas T r acer port able g as monitor s. It is de signed to s ave the calibrati on and bump test reco rds to a USB flash drive (standalone functionality) or to be connected directly to a computer (PC controlled functionality). If calibration and bump test records are stored to a USB flash drive while operating in the standalone configuration, the Single Module Data Viewer Program can then be used with a Windows-based personal computer to retrieve calibration and bump test data files from the USB flash drive or from the computer’s hard drive if the files have been transferred to the hard drive from the flash drive. If you are using the PC Controller Program while operating in the PC controlled configuration, you may retrieve instrument data, bump test, and calibrate up to 10 units at once. Instrument information and data for each instrument can be viewed directly using the PC Controller Program and can be printed from the PC Controller Program. For instructions to use the SDM-2012 in th e S tan dalone config uration, see th e SDM-2012 Docking Station Standalone Configuration Operator’s Manual.

USB Hub Requirements for Multiple Station Systems

If you have more docking stations than you have available USB ports, you will need a USB hub. RKI provides both a 4-port hub and a 7-port hub. If you have more than 7 docking stations, you will need to purchase one of each hub. Do not connect one hub to the other. Make sure that each USB hub has its own USB port on your computer. You may also purchase your own USB hub of any port number from your local electronics store but it must meet the following requirements:

•USB 2.0

• compatible with your Windows

An AC adapter comes with the USB hub(s) sold by RKI but does not need to be plugged in for SDM-2012 operation. If the hub will be used to charge other devices, the AC adapter needs to be plugged in.

Hardware Setup

Figure 13: SDM-2012 Arrangement

This section describes how to assemble the hardware that came with the SDM-2012, assemble a manifold, and connect calibration gas.

Hardware Assembly

The hardware assembly consists of connecting the AC adapter(s), installing the air filter(s), installing the check valve(s), connecting the sample tubing and connecting the USB cable(s). The SDM-GX Docking Station PC Controller software can support 1-10 SDM-2012 docking stations connected at the same time. Perform the following steps to complete the hardware assembly for each SDM-2012:

1. Place the SDM-2012(s) on a convenient table top near an AC wall socket or

power strip in a well ventilated area. A location near a window that can be opened is best so that the exhaust can be routed to the window.

2. If you have more than one SDM-2012, arrange them side by side as shown in

Figure 13 below. Each docking station has three connection tabs on the left side near the bottom of the station and three connection recesses on the right side near th e bottom of the station. The tabs from one docking statio n can be pushed into the recesses on another station to mechanically connect the docking stations.

3. Insert the round plug on the end of each AC adapter’s cable into the power

jack on the back of each SDM-2012.

NOTE: If you have multiple SDM-2012s and are using a 3-port AC adapter,

plug each of the round plugs on the end of the AC adapter into the power jack on th e back of 3 separate SDM-2012s.

4. Connect the AC adapter’s wall plug into a wall AC socket or power strip.

8. Install the 3 foot long 3/16 inch ID tubes that are included with the SDM-2012

on the GAS 1 and GAS 2 fittings. GAS 1 and GAS 2 tubing from multiple units can be daisy chained together in a manifold for more convenient operation. See "Assembling a Manifold for Multiple SDM-2012 Units" below for instructions.

9. Connect the provided USB cord from the type B USB port on the bac k of the

SDM-2012 to an available USB port on your computer or to a USB hub that is connected to your computer. See “USB Hub Requirements for Multiple Station Systems” on page 12 for more information about USB hubs.

Assembling a Manifold for Multiple SDM-2012 Units

Up to 10 SDM-2012 s can be manifolded together and draw from one gas cylinder. If you only have standard 4-gas GX-2012s, you only need to create a manifold for the GAS 1 fitting. If you have a st andar d 4-gas GX -201 2 plu s a %volu me sens or, you will need to create one manifold for the GAS 1 fitting and another manifold for the GAS 2 fitting. If you have a Gas Tracer of any configuration, you will need to create one manifold for the GAS 1 fitting and ano ther ma nifold for the GAS 2 fitting. Th e exhau st lines can also be manifolded together and be routed away from the docking stations with only one 10 foot long 5/16 inch piece of tubing.

Each SDM-2012 is shipped with exhaust tubing, GAS 1 and GAS 2 tubing, T-fittings in two different sizes, and a check valve.

Connecting Calibration Gas

The GAS 1 and GAS 2 fittings on the back of the docking station are designed to be used with a calibration gas cylinder that is fitted with a demand flow regulator. The AIR fitting may be used with a demand flow regulator and a cylinder of zero emissions air, but this is not normally necessary since the docking station will generally be in a fresh air area.

The type of calibratio n g as cyli nd er u s ed de pen ds on the gas sensors installed in the instrument being used w ith the cal ibration st ation. Typically a 4-gas m ix will be used if the instrument being used with the calibration station is a 4-gas GX-2012 . If a 5sensor GX-2012 is being used, a 100% volume methane cylinder will also be needed.

If a Gas Tr acer is being used, a 1000 p pm me thane cylinde r and a 3-g as cylinde r are needed. If a Gas Tracer with a %volume sensor is being used, a 1000 ppm methane cylinder, a 3-gas cylinder, and a 100% volume methane cylinder are needed. The 1000 ppm methane cylinder should be connected to the GAS 2 fitting first. The docking station will begin every bump test or calibration with the ppm sensor. The user will need to ch ange th e GAS 2 cylinder to the 100% volu me m ethane cylin der (i f %volume sensor installed) when prompted to do so by the PC Controller Program during bump testing an d calib ra ti on .

Use Table 2 below as a guide in determ ining which and how many calibration gas cylinders are appropriate for your system.

NOTE: Do not use a 4-gas cylinder or any cylinder that includes H2S when

bump testing or calibrating a Gas Tracer. H2S adversely affects the ppm combustible sensor.

To connect calibration gas to the SDM-2012, do the following:

1. If the area around the docking station is not considered a fresh air area (an

area free of combustible and toxic gases and of normal oxygen content,

20.9%) install a tube not longer than 10 feet on the filter attached to the AIR fitting on the back of the docking station and route it to a fresh air area or connect a cylinder of zero air with a demand flow regulator to the AIR fitting.

2. Install the demand flow regulat or on the calibration gas cylin der(s).

3. Connect the demand flow regulator to the GAS 1 or GAS 2 inlet fitting using

the 3 foot length of 3/16 inch ID sample tubing provided with the docking station.

For a 3- or 4-gas mix, connect the regulator to the GAS 1 inlet. For a special calibration cylinder (ppm or %volume), connect the regulator to

the GAS 2 inlet.

NOTE: If you have set up a ma nifold for ca librati ng instr ume nt s, the r egula tors

can be connected to tubing leading to the manifold inlet in stead of connected directly to the GAS 1 or GAS 2 inlet fitting.

Automatic Bump Testing and Calibration

The PC Controller Program will automatically perform a bump test or calibration on a connected instrument if Auto Bump Test or Auto Calibration is selected in the Configuration Window and if the bump test or calibration is due. The use of these features allows the user to launch the PC Controller Program, turn on the instrument(s) and walk away. No oversight of the bump test or calibration is needed. For this reason, the calibration cylinders need to already be in place and the instrument configura tion s must be such that the gas cyli n de rs do not requ i re any changing.

If Standard GAS is selected in the Configuration Window, only the standard sensors (catalytic LEL, O2, CO, and H2S [GX-2012 only]) will be tested. If All GAS is selected,

all sensors will be tested in every instrument configuration except for a Gas Tracer with a %volume sensor installed. Gas Tracers with a %volume combustible gas

51 • Automatic Bump Testing and Calibrat ion

sensor installed cannot be fully bump tested or calibrated automatically because they will always need a gas cylinder chan ge during bump testing or calibration. The PC Controller Program will bump test or calibrate only the standard 3 sensors (catalytic LEL, O2, and CO) if Auto Bump Test or Auto Calibration is selected. RKI Instruments,

Inc. recommends that you manually bump test or calibrate any Gas Tracers with a %volume sensor installed using the PC Controller Program as described in “Bump Testing a Gas Tracer” on page 77 and “Calibrating a Gas Tracer” on page 95.

To automatically bump test or calibrate an instrument or instruments:

1. Be sure that Auto Bump Test or Auto Calibration are selected in the Configuration Window. See “Setting Up the PC Controller Program” on page 32 for instructions.

2. Verify that all of the bump test and/or calibration parameters are set correctly. See “Setting Up the Configuration” on page 32 for instructions.

3. Verif y that the appr op r iate cal i bra ti on ga s cylind er or cylin de rs is con ne cted to the appropriate manifold line.

4. Ensure that the gas out to instrument line is connected to the inlet of the instrument.

5. Establish a connection between the SDM-2012, instrument, and the PC Controller program as described in “Connecting Instruments to the P C Controller Program” on page 43.

6. The bump t est or calibration will begin 1 minute after the last connected instrument’s instrument information download is complete.

7. During an automatic bump test, if the bump test fails, a calibration is immediately performed.

8. If Auto Bump Test and Auto Calibra tion are both selected, the calibration will begin 1 minute after the bump test has finished.

Bump Testing a GX-2012

The following instructions apply to GX-2012s with one or more of the standard four sensors (catalytic LEL, O2, H2S, and CO) when you are using only a 3-gas or 4-gas

cylinder. RKI Instruments, Inc. recommends using a 3-gas or 4-gas cylinder instead of multiple cylinders for calibrating standard instruments. These instructions also apply to GX-2012s with a %volume sensor installed when you are using a 3-gas or 4gas mix and a %volume calibration cylinder. For instructions to bump test a Gas Tracer, see “Bump Testing a Gas Tracer” on page 77.

The PC Controlle r Prog ram is capable of performing a bump test both manua lly and automatically wh en a GX-20 12 is con nected to i t. When a bum p test is pe rformed, the PC Controlle r Pr og ra m performs an air adjust operation on a GX-2012 and then applies calibration gas to the instrument. The program analyzes the response results based on predefined criteria and determ ines if the GX-2012 passed the bump test.

The criteria that the PC Controller Program uses to determine if the GX-2012 passes a bump test, whether the Bump Test button is active, and whether or not the PC Controller Program automatically performs a bump test if it is due on a connected

Calibrating a GX-2012

The following instructions apply to GX-2012s with one or more of the standard four sensors (catalytic LEL, O2, H2S, and CO) when you are using only a 3-gas or 4-gas

cylinder. RKI Instruments, Inc. recommends using a 3-gas or 4-gas cylinder instead of multiple cylinders for calibrating standard instruments. These instructions also apply to GX-2012s with a %volume sensor installed when you are using a 3-gas or 4gas mix and a %volume calibration cylinder. For instructions to calibrate a Gas Tracer, see “Calibrating a Gas Tracer” on page 95.

The PC Controller Program is capable of performing a calibration both manually and automatically on a GX-2012. When a calibration is performed, the PC Controller Program performs an air adjust operati on on a GX-2012 and then applies calibration gas to the GX-2012. The PC Controller Program analyzes the calibration results and determines if the GX-2012 passed the calibration.

To manually calibrate an instrument or instruments:

1. Establish a connection between the SDM-2012, GX-2012, and the PC Controller program as described in “Connecting Instruments to the P C Controller Program” on page 43.

2. Verify that all of the calibration parameters are set correctly. See “Setting Up the Configuration” on page 32 for instructions.

3. Verif y that the appr op r iate cal i bra ti on ga s cylind er or cylin de rs is con ne cted to the appropriate SDM-2012 or manifold line.

4. Ensure that the gas out to GX-2012 line is connected to the inlet of the GX-2012 and that the exhaust line is connected to the exhaust fitting of the GX-2012.

Bump Testing a Gas Tracer

The following instructions apply to standard Gas Tracers that contain the standard sensors (catalytic LEL, ppm combustible, O2, and CO). They also apply to Gas

Tracers tha t have a %volume comb ustible gas sensor inst alled. See “Bump Testing a GX-2012” on page 52 for instructions to bump test a GX-2012.

The PC Controlle r Prog ram is capable of performing a bump test both manua lly and automatically when a Gas Tracer is connected to it. When a bump test is performed, the PC Controlle r Program p erforms an air adju st operatio n on a Gas T race r and then applies calibration gas to the instrument. The program analyzes the response results based on predefined criteria and determines if the Gas Tracer passed the bump test.

The criteria that the PC Controller Program uses to determine if the Gas Tracer passes a bump test, whether the Bump Test button is active, and whether or not the PC Controller Program automatically performs a bump test if it is due on a connected Gas Trace r is defined in the Param eter ta b of the Configurati on Window. See "Setting Up the Configuration" step 9 on page 35 for a description of the bump test configuration setup.

NOTE: The PC Controller prog ram perform s a complete bu mp test on the ppm

combustible sensor first. Be sure that the 1000 ppm methane calibration cylinder is connected to the GAS 2 fitting on the back of the SDM-2012 using a 6 inch humidifier tube.

To manually bump test an instrument or instruments:

NOTE: Do not use a 4-gas cylinder or any cylinder that includes H2S when

bump testing a Gas T racer . H2S adversely affect s the ppm combustible sensor.

1. Establish a connection between the SDM-2012, Gas Tracer, and the PC Controller program as described in “Connecting Instruments to the P C Controller Program” on page 43.

2. Verify that all of the bump test parameters are set correctly. See “Setting Up the Configuration” on page 32 for instructions.

3. Verify that the appropriate calibration gas cylinder(s) are connected to the appropriate SDM-2012(s) or manifold line(s). The ppm sensor will be bump tested first. Be sure that a 6 inch humidifier tube is used to connect the ppm calibration cylinder to the GAS 2 fitting on the back of the SDM-2012 or that a humidifier manifold has been assembled for the GAS 2 fittings (see “Assembling a Manifold for Multiple SDM-2012 Units” on page 15). If you are using a zero air cylinder for the fresh air adjustment, install a 6 inch humidifier tube between the regulator and the AIR fitting on the back of the SDM-2012.

4. Ensure that the gas out to instrument line is connected to the inlet of the Gas Tracer and that the exhaust line is connected to the exhaust fitting of the Gas

bump test. The gas concentration shown next to each channel is the auto calibration value for that channel. If it does not match the gas concentration in the cylinder(s), change the auto calibration value for that channel. See “Sensor Tab” on page 165 for instructions. If you are bump testing a standard Gas Tracer, leave the first ch annel (the ppm sensor) d eselected and select all othe r channels.

9. You will then be asked to confirm the auto calibration values and the instruments that the calibration cylinder will be used for. Be sure the auto calibration values match the values listed on the calibration cylinder . The serial number and gas combination of all se lected instruments will appear sequentially beneath the gas cylinder concentrations. If you are bump testing a standard Gas Tracer or Gas Tr ace rs (ca talytic LEL, ppm combustible, O

CO), the screen will appear as shown below. The ppm sensor will be bump tested first with GAS 2 and then the remaining 3 sensors will be bump te sted with GAS 1. The GAS 2 selection bo x is deselected by default. You must select the GAS 2 box if you wish to bump test th e pp m combustible sensor. If you do not wish to bump test the ppm combustible sensor, leave the GAS 2 box deselected.

The SDM-2012 will bump test the ppm sensor using the Gas Tracer’s WET setting for the fresh air adjustment and the gas application. This is not user adjustable us ing the PC Controller Program. If the SDM-2012 is not in a fresh air environment, a zero air cylinder must be used with a 6 inch humidifier tube connecting the cylinder to the AIR fitting. Another 6 inch humidifier tube or a humidifier tube manifold must always be used to connect the calibration gas cylinder to the GAS 2 fitting. If you need to perform a DRY bump test for any reason, it must be done away from the SDM-2012. See the Gas Tracer Operator’s Manual for a description of the DRY and WET settings for bump testing and calibration.

Calibrating a Gas Tracer

The following instructions apply to standard Gas Tracers that contain the standard sensors (catalytic LEL, ppm combustible, O2, and CO). They also apply to Gas

Tracers that have a %volume combustible gas sensor installed. See “Calibrating a GX-2012” on page 65 for instructions to calibrate a GX-2012.

The PC Controller Program is capable of performing a calibration both manually and automatically on a Gas Tracer. When a calibration is performed, the PC Controller Program perfo rms an air adjust operation on a Gas Tracer and then applies calibration gas to the Gas T racer. The PC Controller Progra m analyzes the calibration results and determines if the Gas Tracer passed the calibration.

NOTE: The PC Controller program performs a complete calibration on the

ppm combustible sensor first. Be sure that the 1000 ppm methane calibration cylinder is connected to the GAS 2 fitting on the back of the SDM-2012 using a 6 inch humidifier tube.

To manually calibrate an instrument or instruments:

NOTE: Do not use a 4-gas cylinder or any cylinder that includes H2S when

calibrating a Gas Tracer. H2S adversely affects the ppm combustible sensor.

1. Establish a connection between the SDM-2012, Gas Tracer, and the PC Controller program as described in “Connecting Instruments to the P C Controller Program” on page 43.

2. Verify that all of the calibration parameters are set correctly. See “Setting Up the Configuration” on page 32 for instructions.

4. Ensure that the gas out to instrument line is connected to the inlet of the Gas Tracer and that the exhaust line is connected to the exhaust fitting of the Gas Tracer.
