WARNING: dangerous gases!
The chromatograph operates with various gases which may be more or less dangerous.
Before carrying out work on the chromatograph, always determine which gases the chroma-
tograph is operating with, in particular the composition of the sample gas.
Pass all exhaust gases from the chromatograph into a common line and route away from the
installation location.
Always make sure that there is sufficient ventilation
n if you are working with hydrogen since this forms an explosive mixture with airn if you are working with liquid CO2. Breathing in of larger quantities of CO2 results in an
oxygen deficiency even up to unconsciousness or death through suffocation.n if you permit the sample gas line to run empty, and the sample gas contains corrosive or
toxic components.
The analysis of mixtures containing CS2 is not permitted.
WARNING: danger of explosion!
The chromatograph may require gases for operation which form an explosive mixture with
air!
Before carrying out work on the chromatograph, always determine which gases the chroma-
tograph is operating with.
Pass all exhaust gases from the chromatograph into a common line and route away from the
installation location.
Always make sure that there is sufficient ventilation.
WARNING: danger of explosion!
The chromatograph is intended for the analysis of gaseous flammable and non-flammable
media. Hydrogen or inert gases are used as carrier gases. In the analysis of flammable me-
dia or when using hydrogen as the carrier gas, only traces of oxygen occur in the sample; inother cases, the oxygen content of the sample is limited to the concentration that normally
occurs in inhaled air.
The analysis of mixtures of flammable gases and other gases at a pressure of > 1.1 bar isnot permissible for explosive mixtures.
Flammable gases that are explosive under the conditions relevant to the analysis, even with
the exclusion of oxygen, may only be contained in the mixture for analysis in concentrationsthat are not critical for safety.
CAUTION: danger of corrosion!
The housing is extremely resistant to solvents, weak alkalis and acids. When used in envi -
ronments with strong alkalis and acids at increased temperatures, the resistance should be
tested in individual cases.

Explosion protection
The installation and operation of electrical equipment in potentially explosive atmospheres is re-
gulated by the guideline RL 99/92/EU (ATEX 137). Reference is made in this guideline to general
technical regulations.
WARNING:
The test certificate for your explosion-proof chromatograph only applies to the original confi-
guration with connection and installation according to the Siemens circuit and piping dia -
grams. The explosion protection for your device is cancelled if one or more components are
modified.
Conditions
The test certificate together with any supplements includes all conditions specified for installation and
operation of the chromatograph.
Identification for explosion protection
The chromatograph is flameproof, i.e. the housing is resistant to an internal explosion pressure. The
housing of your MicroSAM has a rating plate on which the identification for explosion protection is spe-
cified: II 2 G EEx d IIC T4
Switching on the chromatograph
The power supply to the chromatograph must only be switched on if it has been correctly connected!
Opening the housing with the power supply switched off
Before opening the housing in the potentially explosive atmosphere, the power supply must be switched
off and an essential waiting time of 60 minutes subsequently observed.
WARNING:
As a result of hot components and residual electric charges in the chromatograph, explo-
sions may occur if the housing is opened too soon. A corresponding reference to this is pre-
sent on the chromatograph!
Opening the housing with the power supply switched on
A diagnostics plug is located behind the status display panel. The housing must be opened in order toaccess this. In the potentially explosive atmosphere, this is only permissible with a fire permission certi-ficate.
WARNING:
Opening the housing in the potentially explosive atmosphere with the power supply switched
on is only permissible with a fire permission certificate.

IMPORTANT:
All chromatograph-specific connection diagrams can be found in the manual in the RegisterExternal piping and wiring diagrams.
CAUTION:
The 3mm adaptors at the gas connections 3, 4 and 5 are containing a filter each.They must not be removed.
Sample linesn The sample conditioning must be fitted close to the chromatograph so that the connection lines are
short.n The sample line to the chromatograph should have a downward gradient.
IMPORTANT:
The injector valves have a shorter life if the sample contains solid components! A filter is re -
quired upstream of the injector in this case. We recommend filters with a separating ca pacity:
n Liquid sample: 98% for 0.3 m particlesn Gaseous sample: 99.99% for 0.1 m particles.
Siemens sample conditioning units contain such filters.
Exhaust lines
All exhaust gases from the chromatograph must be routed into a common line. The individual exhaust
lines must have a downward gradient to the common line. Their diameter must not be reduced.
Material of common exhaust line
Stainless steel pipe with an internal diameter of at least 12 mm (1/2") with welded couplings and scre-
wed glands. Minimum downward gradient 1 : 10.
Breathing device
If the MicroSAM housing is purged with air or inert gas, a piping can be connected here. This piping
must be designed in such a way that atmospheric pressure conditions are present in the piping system.
WARNING: Breathing device
The breathing device may not be locked!
Power switch and fuse
The chromatograph does not have a power switch. A power switch and fuse with a rating of 2.5 A at
min. 24 V must be fitted in the building installation. The power switch should be installed close to the
chromatograph.
Connecting the power supply cable
The chromatograph is delivered with a 4-m long cable. The cable diameter is 18 mm.

Equipotential bonding cable / earthingAn equipotential bonding cable is required for explosion-proof chromatographs depending on the local
installation regulations. Independent of this, the housing of the MicroSAM must be earthed for electro -
magnetic compatibility reasons.
Connect the earthing screw (symbol r) at the back right on the chromatograph to a central earthing
point. Cable cross-section 2.5 to 6 mm2. The contact washer must always be present between the cable
lug and the housing. Sequence: housing, contact washer, cable lug, plain washer, M6 screw.
Lightning protection
In areas where storms occur, we recommend appropriate lightning protection equipment to protect per-
sonnel and equipment. The following are required for comprehensive protection:
n Lightning conductorn Earthed metal band in building to protect against static charges. This is especially important at grea-
ter heights and with dry air.n Transient suppressor in all lines leading to the chromatograph. These are available e.g. from Phoenix
Contact.

Cable type
We recommend twisted pair cables, 0.14 mm2, shielded, AWG 26.
Conversion of serial interface to RS232 or RS485
MicroSAM has only one serial interface which can be switched between RS232 and RS485. It is neces-
sary to assign com1 to RS232 and com2 to RS485 in the System Manager, as described in the SystemManager instructions.
Terminating resistors for MODBUS with RS485
RS485 cables must be terminated at both ends with 120- resistors in order to prevent reflections. This
resistor is present in the MicroSAM. It can be switched on using the software. This is usu ally carried out
in the MicroSAM which is furthest away.
CAUTION: explosion protection
All conductors must be connected in the junction box. This means that cables must not have
more conductors than are actually required.
Always refer to the connection diagram.

Operation
MicroSAM can be operated via Ethernet and a PC, or via the built-in control panel (MMI) of a MAXUMchromatograph, or via a network access unit (NAU).
Various stages of operation
Operation on the PC comprises three stages:
n System Manager - network monitoring and configuration of the chromatographn EZChrom - development of method and control of analysisn MMI emulation - operation and monitoring
System Manager configure database and applications
Provides the connection to the chromatograph, and an overview of the network.
Serves for configuration and high-level monitoring of the chromatograph. Also branches to the MMI
emulation, EZChrom and the basic editor.
The System Manager outputs almost exclusively static displays, i.e. it fetches a table from the chroma -
tograph's database, and saves it again later. Only results and alarms are displayed in dy namic mode.
The System Manager displays the hardware in tables, i.e. the system table includes all hardware com-
ponents of the chromatograph: detectors, valves, ovens, digital outputs etc.
EZChrom generate methods and sample sequences
Methods and sample sequence lists of an application can be generated and modified using EZChrom,
e.g. optimize evaluation parameters, modify time programs, display chromatograms and results, re-inte-gration.
Access to the chromatograph's database is exclusively static.
MMI emulation operation and monitoring
This is identical to operation on the built-in control panel of a MAXUM or an NAU. It is used for operati-
on and monitoring, e.g. view results, switch valves, modify temperatures. However, there are only mini-mum facilities for editing configurations and tables.
MMI is always a dynamic display.
Where and how the data are organized
One must be acquainted with the following terms when using the chromatograph: database, application,
methods, sample sequences.
The database
All parameters of a chromatograph are saved in a database. This contains configuration data and appli-
cations of the System Manager, EZChrom methods, sample sequences, archive and alarm log. This da -
tabase can be viewed in static or dynamic mode.
Staticcorresponds to a snapshot of the database, i.e. tables are imported from the database into the
PC, edited, and subsequently exported to the chromatograph again. The display is not automatically up-
dated. The data must be imported again in order to view modifications.
Dynamic means that the values are updated as soon as they change. Most of the MMI displays are dy-
namic. With the System Manager, only the results and alarms. EZChrom is always static.
In the System Manager, copies of the database can be saved on the hard disk, and saved da tabases
loaded into the chromatograph (file extension.AMD).
Application
Applications share the chromatograph hardware. Parts of the system table are assigned to each appli-
cation. These quasi generate a virtual chromatograph. Each application has sample flows, one or more
sample sequence lists, inputs/outputs, several EZChrom methods, basic programs, chromatograms,
temperature controllers, pressure regulators, results.
Operation
26 SAM-Manual_E.vp, Issue 06.05.2004
-
7/29/2019 SAM Manual E
27/49
Each chromatograph can have several applications.
Methods
A method contains information required to analyze a sample stream: configuration data of detectors,valves etc., peak detection parameters and evaluation parameters, time programs. Methods are genera-
ted using EZChrom and exported to the chromatograph's database.
Sample sequences
These are lists of sample streams and assigned methods. Each application has at least one normal se-
quence and one calibration sequence. Although an application can have several sequences, only one is
active at a time.
How the data originaten When the chromatograph is switched on for the first time, it automatically generates the required en -
tries in the system table by Plug&Play. However, the chromatograph only recognizes, for example,
that it has an electronic temperature controller, but does not know which type of oven is to be con -trolled using it.
n In the second step, all hardware of your chromatograph is completely written in the factory by a confi-
guration program. The existing hardware is then assigned to one or more applications. The configura-tion program generates a text file which is imported into the chromatograph by the System Manager.
n The applicable data are subsequently determined, and entered using EZChrom: valve switching, eva-luation parameters etc. These data are saved as methods and a sample sequence list using EZ-
Chrom.n All data are finally exported together from the chromatograph's database as an AMD file using the
System Manager, saved with the remaining documentation on a CD, and supplied with the chromato-graph.
Monitoring the chromatograph's function
MicroSAM is completely parameterized when you switch it on (if you didn't order a basic unit and an an-
alytical module separately). It need only be integrated into the communication network, and calibrated of
course. It is subsequently only necessary to monitor correct functioning at regular intervals.
The LEDs
The LEDs behind the inspection window of your MicroSAM provide a initial impression of the status of
your MicroSAM. They have the following meanings:

Establishment of communication
The IP address is factory-set in the MicroSAM to 192.168.144.0xx. "xx" corresponds to the last two di -
gits of the serial number on the rating plate. For example, the IP address is 192.168.144.047 if the seri-
al number of the MicroSAM is HX R5 347. The Subnet mask is always 255.255.255.0.
To permit your PC to communicate with the MicroSAM, its IP address must be in the same "world". This
means that its IP address must be manually set to 192.168.144.0 to 255, but of course must not be
identical to the IP address of the MicroSAM. We recommend that you set 192.168.144.254, and
255.255.255.0 as the Subnet mask.Once the System Manager has started, the new chromatograph must be entered using the functionAdd
Unit. More detailed information on the subject of Ethernet networking can be found in the description of
the System Manager.
Alarms
Open the associated chromatograph in the System Manager, and click on Alarm Log. All alarms are dis -
played here. These alarms can be deleted so that it is possible to check whether they occur again.
Checking the chromatogram
EZChrom can be used to compare the current chromatogram with previous chromatograms. This per -mits conclusions to be made concerning changes in the analytical system.
Checking the results
EZChrom can be used to check whether the results are complete and realistic.
IMPORTANT
The number of time events in EZChrom for MicroSAM must not exceed eight at the sameexecution time (Retention windows, valve switching etc.). Otherwise you will get an error
message later while executing the time events.
If you need more than eight time events at the same execution time, you must use slightly
different execution times for groups of eight time events each.

Maintenance of the analysis module
We use standardized analysis modules with MicroSAM. They are very powerful and thus are suit ablefor many different applications.
The most important feature is the in-line detection. The columns and the thermal conductivity detectors
(TCD) are connected in series. So MicroSAM can collect the results from the locations, where the com -
ponent separation is optimum.The TCDs are semi bridges w/o reference. Two TCDs are connencted in each case to a completebridge circuit in a way, that no overlapping of signals will occur.

Removing the analysis module
WARNING
Observe the regulations for explosion protection if the MicroSAM is installed in a potentially
explosive atmosphere.
When using the chromatograph in explosion hazardeous areas, a waiting time of 60 min.must be observed before opening the housing. After this time, the surface temperatures in-
side the chromatograph have cooled to < 135C and the electrical charge of internal compo-
nents will have reduced to an uncritical level.
n Loosen the hexagon socket screw (1.5 mm) in the top cover of the MicroSAM by two rotations.n Unscrew the top cover. If the cover cannot be opened by hand, you can increase the lever arm e.g.
by inserting two matching screwdrivers into the holes at the edge of the cover.n Remove the insulation.

WARNING
The explosion protection regulations specify that the covers of the MicroSAM housing areprotected against unintentional opening by a locking screw.
These screws must be loosened before opening.
After locking, these locking screws must be tightened.
n It is still necessary to load the analyzer parameters after switching on the MicroSAM again. To do
this, import the supplied text file into the MicroSAM as described in the documentation of the System
Manager.
Adjusting mechanical zero of the pressure regulators
If the pressure regulation is under suspicion to cause faulty analytical results, e.g. shifted retention
times, the function of the pressure regulators should be checked, and the mechanical zero should be
adjusted if necessary
WARNING
This service procedure may only be carried out by trained experts.
Danger of causing short circuits at the electronical boards.
For adjusting the mechanical zero the appropriate special tool has to be used.
On MMI in Maintenance Mode select the menu App I/O, Temperature & Pressure and in this menu theitem Pressure Controller. In the column PWMyou see the controller output signals for the four pressure
regulators. The controller output should read 10 to 30 %. If this value reads 0 or 100 %, the mechanical
zero should be adjusted.
Using the MMI, adjust the set value for the pressure according to the application documentation. Thenuse the special tool to adjust the pressure regulator until the PWM value reads approximately 20 %.
The photo shows the position of the pressure regulators. On the lower left you will find reg ulator 1 (yel -
low arrow), the numbers increase counterclockwise. While adjusting, off course, the electronic boards
are in place. You have to find the pressure regulators by "feeling" with the special tool.

The Live injection
The injection volume of the Live injection system can be adjusted by time events for the in jection valve.Thus a small well defined amount of sample is cut out of a big sample flow.
Filling the injection loop
The injection loop is beeing filled with sample.
Purging the injection loop
The injection loop is purged via the Live injection piece to the backflush vent.
Injection
A small part of the injection loop's volume is purged into the column. This injection volume can be
defined by modifying the pulse width for the injection valve.

The Live column switching
Two columns are connected in series by the Live T-piece. The columns have e.g. different sepa-
rating characteristic. The various operating states of the live switching circuit are activated by
pressure changes in the gas supply lines of the Live T-piece: Straight, Backf lush, Cut. The elec-
tronic pressure regulators are controlled by time events.
Straight
The components pass through two columns in suc-
cession.
Backflush
Once a number of components have passed
through the first column, the flow direction in this
column is reversed. The components which are
still present in the first column are collected againat the beginning of this column and flushed out
into the open air via the backflush outlet.
This permits the analysis cycle to be drastically shortened: higher boiling components which only pass
through the first column slowly need not be removed at a higher temperature, a process which often re-
quires a long time.
Cut
Once a number of components have passed
through the first column, they are flushed out
through the cut outlet. They never reach the sec -ond column.
This method is used:
n to keep components away from the second column which cannot be backflushed because they are
followed by components which are still of interestn if components falsify the result or damage the second columnn to directly pass components onto a further detector, e.g. in order to shorten the duration of the analy-
sisn to divide components further on a third column (distribution).
Advantages of live switchingn The sample only comes into contact with metal parts in the live T-piece, but with no valves.n There are no temperature limitations because the switching valves are mounted outside the oven.n Maintenance-free since there are no moving parts.n Minimum dead volume, highly suitable for capillary columns.

How Live switching functions
Pressures and flows are important
Two columns are connected in series, and a pres-
sure of P1 is connected to the beginning. Atmo-
spheric pressure is present at the end. The pres -
sure distribution and flows are then as shown onthe left.
Conclusion:
In the straight operating mode shown here, the
pressure P2 is present in the middle between the
two columns.
NOTE:
In reality, the pressure drops are not linear, they are
curved.
Time for reflection
The pressure P2 read on the Y-axis in the above
figure is now applied between the two columns.
The input of the first column is left open. This re -
sults in a pressure distribution and flows as shown
on the left.
Conclusion:
Backflushing is now being carried out in the first
column.
What we don't know yet ...
If we wish to prevent a specific peak from disappearing into the second column once it has passedthrough the first column, we need an outlet betwwen the columns (cut outlet). And we need a connec-tion for he pressure P2 from the reflection above. The solution is the live T-piece.
The two columns are connected via the coupling capillary in the Live T-piece (red in the right image be-
low). Because this coupling capillary has a flow resistance, we have to recognize two pres sures now:
P2 after the coupling capillary and P3 before the coupling capillary. In the Straightmode everything re -
mains like mentioned above at Pressures and flows are important. Just P3 has been added.

And now the cutWe set P3 a bit lower than P2. The result is shown
on the left. The components are flushed into open
air as soon as they leave the first column.
Because the pressure on the left hand side of the
coupling capillary is lower than the pressure at the
right hand side, all the gas from the first column is
forced to leave via the cut outlet!
If it really were that simple ...
... then we would be finished. Why does live switching therefore have to the adjusted? This we have
done for you already in the factory. But it may be helpful for you, to understand the procedure anyhow:
The live T-piece has 6 connections, of which the three right ones can be outputs. This means that a
peak can be divided simultaneously amongst up to three outputs. And we can do without that!
So we will inject a test mixture and monitor the detector signals at the three outlets. Then we have todecide, how to change the pressures P2 and P3, to get clear flow conditions forStraightand Cut:
Straight
Everything from the first column must enter thecoupling capillary, and everything from the coupling
capillary must enter the second column. This func-
tions reliably if the "red" flow is supplemented by
the flows of the auxiliary inlets P2 and P3. The
flow direction in the coupling capillary is from left to
right.

Cut
Everything from the first column must pass on tothe cut outlet. This functions reliably if the "red"
flow is supplemented by a sufficient flow of the
auxiliary inlet P2. P2 also supplies the second col -
umn. The flow direction in the coupling capillary is
now inverted from right to left.
The flow P3 decreases automatically.
Backflush
Backflushing functions exactly as described previously underTime for reflection. The position in which
the live T-piece is currently being operated is irrelevant.

Removal of electronic modules
WARNING
Observe the regulations for explosion protection if the MicroSAM is installed in a potentiallyexplosive atmosphere.
When using the chromatograph in explosion hazardeous areas, a waiting time of 60 min.must be observed before opening the housing. After this time, the surface temperatures in-
side the chromatograph have cooled to < 135C and the electrical charge of internal compo-
nents will have reduced to an uncritical level.
n Loosen the hexagon socket screw (1.5 mm) in the bottom cover of the MicroSAM by two rota-
tions.n Unscrew the bottom cover. If the cover cannot be opened by hand, you can increase the lever
arm e.g. by inserting two matching screwdrivers into the holes at the edge of the cover.n Loosen all electrical connections.n Loosen the six T30 Torx screws.
n Carefully remove the RSP module.
CAUTION: electrostatically sensitive devices!Before touching such components or modules:
n Switch the chromatograph off.n Discharge all static from yourself by touching a grounded object or by wearing an ESD
wrist band.n Only use tools which are free of static charges.n Do not touch any pins or printed conductors. Only hold modules on their edges.

Fitting of electronic modules
Fit in the reverse order to the removal instructions above
CAUTION
Make sure that the modules are fitted in the correct position:
n The EPC module has three plug connectors. The side on which the connector is "missing"must point towards the cable bushing of the MicroSAM.
n The RSP module has a cut-out. This must point towards the cable bushing of the Micro-
SAM.
n Carefully unscrew on the cover as far as possiblen Rotate the 1.5 mm hexagon socket screw in the cover (bottom red arrow) clockwise as far as possi-
ble.
WARNING
The explosion protection regulations specify that the covers of the MicroSAM housing areprotected against unintentional opening by a locking screw.
These screws must be loosened before opening.
After locking, these locking screws must be tightened.
n It is necessary to load the analyzer parameters after switching on the MicroSAM again. This is des -
cribed in the documentation of the System Manager.
