5 TERMINOLOGY AND SYMBOLS USED
14.1a ME Gas sampling and gas conditioning technology 7
6 INTRODUCTION
The gas conditioning CSS-VC unit, either for 19 "- or wall mounting or as a portable unit in carrying
case, is a fully pre-assembled compact continuously-operating gas purification system, which,
depending on the design, can supply a sample gas volume of max. 1 x 250Nl/h (CSS VC1) or 2 x
150Nl/h (CSS-VC2). Sample gas conditioning units are suitable due to their equipment and additional
options for the wide-ranging requirements of continuous gas analysis.
The entire gas conditioning unit is housed in a compact, rugged steel housing so that gas analyses
can be performed rapidly without a great deal of effort, with low maintenance and reliability.
Gas conditioning unit CSS-VC must not be used to support gas/air or gas/oxygen mixtures that are
ignitable during operation, for the supply of combustible gases that can form an ignitable mixture in
combination with air or oxygen, or in potentially explosive atmospheres and in potentially explosive
locations.
8 Gas sampling and gas conditioning technology 14.1a-ME
7 APPLICATION
With the CSS-VC, fully pre-installed gas conditioning systems are created for continuous use, which
can be integrated perfectly into analytical systems. The compact design makes few demands on
space. The gas conditioning systems are operational within minutes. This renders time-consuming and
expensive procurement of individual components and small parts and their assembly unnecessary. A
portable version is also available in a carrying case.

All components of the gas conditioning systems are installed in a strong compact steel housing for wall
or 19" mount. The ventilation grilles in the side walls provide adequate forced ventilation.
Filter, flow meter and peristaltic pumps are located in the front panel and thus ensure very simple
maintenance. Due to a removable lid and a hinged front panel, quick and easy inspection and
maintenance of all other built-in components is possible, in particular the easy changing of heat
exchangers.

NOTICE!
Storage of the gas conditioning unit should be in a sheltered frost-free
room!
The current cooler temperature is displayed on the multi-functional control unit TCU mounted on the
front panel. The setpoint temperature of the cooler can be set by pressing keys. In the event of
warnings or faults, plain text information appears on the display and is also indicated by LEDs (e.g.
cooler within the setpoint range and no other alarms - green LED, flow alarm (option) - yellow LED,
temperature ± 3° C from the setpoint and humidity alarm (option) - red LED).
The fine filter downstream of the cooler (different filter types available) provides for the necessary
separation of solids. The condition of the filter can be judged from the outside. To protect the
downstream analysers against liquid penetration and to increase the operating reliability of the whole
system, according to the selected filter type, a suitable liquid alarm is possible or already integrated
into the filter.
A group alarm or on request individual alarms including mA output for the cooler temperature at the
output terminals is available wired. Via potential-free contacts for the group alarm or the individual
alarms (cooler temperature, flow, fluid in the system), an alarm message and shutdown of the sample
gas pump, if present, occurs.
Integrated sample gas pumps are available in three performance levels to choose from N3/5/9 KPE.
The flow meter FM40 arranged in the sample gas outlet with a measuring range adapted to the pump
power can be supplied for flow monitoring with a flow sensor FA-20mo. In addition, each sample gas
line can be equipped with a second sample gas outlet or bypass flow meter and flow control.
In the event of an aerosol problem, a liquid particulate filter CLF can be added downstream of the flow
meter in the sample gas outlet.
Via expansion modules for the control unit TCU two further temperature controllers are available e.g.
to regulate heated lines or gas probes. Here too external sample gas pumps can be connected and
individual sample gas probes can be backflushed.

NOTICE!
So that the unit is safe and operates reliably, it should be mounted
horizontally and without vibration. Only then is proper separation and
drainage of the condensate in the heat exchanger of the cooler
ensured.
The mounting of the gas conditioning unit should take place away from
heat sources and be freely ventilated so that there can be no disruptive
accumulation of heat.
When installed outdoors, adequate protection against direct sunlight
and moisture needs to be ensured. In winter, the place of installation
must be frost-free; ensure correct protection for the device.
Temperature variations, strong air movement and aggressive
atmospheres at the place of installation are to be avoided.
To ensure safe operation of the gas conditioning unit and downstream
analysers and to avoid false alarms, the gas conditioning unit should
not be used outside the specified temperature range. It must also be
protected against the ingress and accumulation of dust.
Downstream analysers and lines must operate at temperatures
significantly above the specified gas outlet dew point of +5 ° C. This
will avoid subsequent condensation of the gas in the connecting lines
to the analysers.
Unheated gas sample lines must be laid on a slope to the cooler.

14 DECOMMISSIONING
On short-term decommissioning of the gas conditioning unit CSS-VC.. no special measures need to
be taken.
For long-term decommissioning, it is recommended to flush the gas conditioning unit with ambient air
or inert gas. A flushing time of 3 to 5 minutes is sufficient under normal conditions. Likewise,
condensate residue must be removed from the system.
15 THE MULTIFUNCTIONAL CONTROL UNIT TCU
The multifunctional control unit TCU in the front panel of the gas conditioning unit CSS-VC.. can
undertake a series of different tasks centrally and provide wide-ranging system information.
15.1 BASIC FUNCTIONS OF THE TCU
1 x temperature controller for the integrated sample gas cooler
Evaluation of max. 2 liquid alarm sensors
Evaluation of max. 2 flow monitoring sensors
An mA output for external cooler temperature display e.g. in the control room
Control (on/off) of 2 sample gas pumps depending on the cooler temperatures and liquid alarms or

26 Gas sampling and gas conditioning technology 14.1a-ME
WA RNUNG!
Before comissioning exclude that for one channel as well
internal as external a PT100 is connected.
15.3 ENHANCEMENTS TO THE TCU
The TCU can be expanded by up to 4 modules in the range of functions. The modules are plugged
together according to requirements and provided for rail mounting.
15.3.1 THE COMMUNICATION MODULE
Communication of the TCU with the expansion modules is always with the communication module via
the M&C bus. This is therefore the base module for all other modules.
The TCU or CSS-VC.. and communication module are connected via RJ45 sockets.
On the communication module there are the temperature sensor ports (PT100 or thermocouples E, J,
T, K, N) of the temperature controller module.
Figure 11 Electrical connections communication module
14.1a ME Gas sampling and gas conditioning technology 27
NOTICE!
If the CSS-VC.. is purchased with an external thermostat module, it
must be specified at the time of ordering which devices should be
regulated (2 probes or 2 heated lines or 1 probe and 1 heated line) so
that the controller can be configured accordingly.
15.3.2 THE TEMPERATURE CONTROL MODULE
The temperature control module includes 2 additional thermostats e.g. for control of heated lines or
gas sampling probes. Control is by control of external solid-state relays. The module also includes 4
relays for high and low temperature monitoring. The connections for the temperature sensors are
located on the communication module.
Figure 12 Electrical connections temperature control module
28 Gas sampling and gas conditioning technology 14.1a-ME
15.3.3 THE STATUS MODULE
On the status module, by the group alarm message of the TCU a changeover relay and a solid-state
relay are connected. These can be used for alarm indication. In addition, external sample gas pumps
can be switched off via two further solid-state relays e.g. in the event of an alarm and switched on
under good conditions. For external control of the pumps, see Section 12.4.2.
Figure 13 Electrical connections status module
14.1a ME Gas sampling and gas conditioning technology 29
15.3.4 THE BACKFLUSH MODULE
With the backflush module, on the TCU a backflush programme can be set for gas sampling probes
(duration of a backflush pulse, number of backflush pulses, time between backflush pulses, timing of
backflush). The programme switches with time delay two solid-state relays with which in turn solenoid
valves can be switched, which accordingly release purging air to the gas sampling probe.
At start and end of a backflush programme, another solid-state relay is switched one second before
start and after the end of the programme, with which a solenoid valve can be controlled, which
releases control air to shut off and open the sample gas output of the gas sampling probe with
pneumatic valve.
In addition, at the start and end of a backflush programme, a changeover relay for status monitoring
(measuring/backflush) is switched. Here at the TCU dead time can be specified to ensure that, on the
"Measure" message, sample gas is currently flowing in the analyser. In addition, a connection is
present for pressure monitoring of the backflush gas. For this purpose, a pressure switch is connected
in the backflush line which closes the contact at upcoming pressure.
Figure 14 Electrical connections backflush module
30 Gas sampling and gas conditioning technology 14.1a-ME
16 OPERATION OF THE MULTIFUNCTIONAL CONTROL UNIT TCU
In normal fault-free operation, the TCU display shows the current cooling temperature and the green
LED is lit constantly when the cooler temperature is within the alarm limits. The bottom line of the
display shows "status: OK" or current warning and error messages.
Figure 15 Front view of the TCU in normal operation without temperature control module
If the external temperature controller module has been purchased with the CSS-VC.., under error-free
normal operation, the temperature of the devices to be controlled (gas sampling probe (probe) and/or
heated sample gas line (B. line)) is indicated.

By 2 x pressing of the arrow key and then 1 x pressing of the PRG key, the following view
appears:
Here it is visible whether the pump is working or not. Using the arrow keys, the pump to be
configured can be selected. By pressing the PRG key again, the following view will appear:
Using the arrow keys, the parameters to be
changed can be selected. By pressing the PRG key,
the parameter can now be changed with the arrow keys

14.1a ME Gas sampling and gas conditioning technology 33
16.3 CONFIGURE BACKFLUSHING
By 3 x pressing of the arrow key, then 1 x pressing of the PRG key, the following view
appears when the backflush module is connected:
Using the arrow keys, the parameters to be
changed can be selected. By pressing the PRG key,
the parameter can now be changed with the arrow keys
and then confirmed with the PRG key or
discarded with the ESC key .
Here the backflushing of gas sampling probes is determined:
Start in = specifies the time of the first backflushing.
Flushing time T1 = Duration of backflushing in a channel
Deadtime = Delay after the end of backflushing in channel 2 until the indication
shows "Measure" (changeover switch on the backflush module is switched)
Interval T2 = Period until the next backflush
On time T3 = Duration of a backflush pulse
Off time = Duration between backflush pulses
Pulse number i = Number of resulting backflush pulses (cannot be entered)
Activation = Backflush programme is to run (on) or not (off). When deactivating, "Start in" = 0
is set.
A programmed backflush runs always automatically after
a delay of T1 on two channels. Thus, for example 2 gas
sampling probes directly following one another or first the
internal probe (/ BB/F), and then the pre-filter (/ BB) are
backflushed. The dead time for channel 1 is therefore
always extended to T1.
If only one gas sampling probe is backflushed, T1 must
be added to the dead time or already represents sufficient
dead time, so that the value for the dead time can be set
to 0.
This menu appears only when the communication module is connected in conjunction with the
backflush module (automatic detection).

messages is specified, e.g. 1/3 ... = Error message 1 of 3.
Depending on the alarm and TCU configuration, an alarm can result in further alarms and warnings:
E.g. the liquid alarm (LA-Alarm:1,2) can trigger the pump alarm (Pump-Warn:1,2) and that in turn can
trigger the flow alarm (FA-Warn.:1,2).
The comm. error (e.g. interrupted connection cable RJ45) causes temperature sensor range exceeded
(T> max.:2,3) and flushing pressure alarm (flushing pressure not present!) as temperature sensors
and pressure sensors are connected to the communication module. From this follows the temperature
alarm (Hightemp.:2.3), then the pump alarm (Pump-Warn:1, 2) (with the appropriate TCU configuration
and then as a result the flow alarm FA-Warn.:1,2).
17.1 MEANING OF THE LEDS

Separate head cover 3 (with metal frame with N3/5) from the intermediate plate 2.
Remove the valve plate 7 and the sealing rings 8 from the intermediate plate.
Check valve seat, intermediate plate and head cover for cleanliness; in the event of
unevennesses, scratches and corrosion, these parts are to be replaced.
Insert the new valve plate 7 into the valve seat of intermediate plate 2; the valve plates for
pressure and suction sides are identical; the same applies to upper and lower sides of the valve
plates.
By slight horizontal movement of the valve plates, ensure that these are not strained.
Insert sealing rings into the intermediate plate.
18.2.4 MOUNT PUMP HEAD TYPE N 3/5/9 KPE
Move structure diaphragm via fan wheel into top dead centre (dead point) position.
Place intermediate plate 2 on the housing with valve plates 7 and 8 as well as head cover 3 in
accordance with the marks (M).
Check its centering by slight lateral movement of the head cover.
Fit metal frame with N3/5.
Only slightly tighten 4 screws diagonally.
44 Gas sampling and gas conditioning technology 14.1a-ME
WA RNING !
Aggressive media residues possible.
On dismantling, repairing or cleaning the pump, protective
glasses and protective clothing must be worn!
Check ease of movement of the pump by turning the fan wheel.
Move structure diaphragm via fan wheel into the top dead centre (dead point) position.
Now hand tighten the screws 4.
18.2.5 CLEANINGTYPE N 3/5/9 KPE
On changing valve plates and diaphragm, prior to assembly of the pump head, all parts should be
checked for contamination and cleaned if necessary.
Wipe the parts as dry as possible with a cloth. Solvents should not be used when cleaning
because they may damage the plastic parts. If oil-free compressed air is available, blow out the
parts.
18.3 MAINTENANCE OF THE BUILT-IN PERISTALTIC PUMP TYPE SR 25.2
Pump hose, belt, pressure rollers and springs are the only wear parts of the pump. They are easy to
change.
14.1a ME Gas sampling and gas conditioning technology 45
WARNING!
Aggressive media residues possible.
On disassembly, repair or cleaning of the hose pump, wear
protective glasses and appropriate protective clothing!
WA RNING !
If you return the hose pump to M&C customer service for repair,
we will ask for information concerning the delivered liquid.
The pump should be cleaned of hazardous or highly aggressive
contaminants prior to return shipment.
Figure 19 Components of the peristaltic pump SR25.2
18.3.1 EXCHANGE THE PUMP HOSE
46 Gas sampling and gas conditioning technology 14.1a-ME
WARNING!
Only the use of original spare pump hose ensures proper
function.
Never lubricate the pump hose.
Check all parts for dirt before assembling the hose pump and
clean if necessary.
Figure 20 Replacing the pump hose
Unplug gas conditioning unit from the mains;
Remove hose connections on the pump;
Squeeze belt using the handles and turn the S-latch clockwise until it stops;
Remove the belt and pull the old pump tubing on the slip fittings out of the guides;
Squeeze the pressure rollers and see if spring tension exists; if not, change pressure springs
(see Section Fehler! Verweisquelle konnte nicht gefunden werden.);
Insert new pump hosewith slip fittings into the guides of the belt;
Insert belt complete with the new hose into the dovetail of the pump body; Squeeze the belt
at the handles and simultaneously turn the S-latch counter clockwise until it clicks;
Switch pump on.
18.3.2 CHANGE OF CONTACT PULLEYS AND SPRINGS
Switch off the mains;
Unscrew nuts of the pump head (wrench size 5,5) and remove snap ring from motor
shaft;
14.1a ME Gas sampling and gas conditioning technology 47
NOTE!
The springs may occur in different coulerings. This does not constitute a
quality defect. But make sure that the right spring strength is used. This
can be identified by the spring wire diameter. The „standard version for
Novoprene pump hoses“ (part no. 90P1010) has a diameter of 1,1mm and
the strengthened version for FPM-, Acidflex- or Masterflex-hoses“ (part
no. 90P1015) has a diameter of 1,2mm.
NOTE!
At first delivery two different types of springs are mounted in the driver
(right and left springs). When spare springs are ordered, for simplified
storage only one type will be delivered (right spring) that can be replaced
without any problems and guarantees full functionality when all four
springs are replaced.
The dent prevents
rotation of the axis
new
worn out
Figure 21 Disassembly of pump head and driver
Draw the pump head out of the motor shaft
Take driver out of the pump head
The removal of the springs (4 pcs.) away from the driver is easily possible without the aid of
any tools. For this take spring out of the groove near to the shaft bore.
Dismount roller axes and change contact pulleys. Take care that axes are not worn out by the
springs and have damaged the dent at the axes front end. In case of abrasion the axes have to
be changed (see Figure 22).
Figure 22 Check of axes and rolls
48 Gas sampling and gas conditioning technology 14.1a-ME
NOTE!
While mounting pay attention to the fit of ‘rotational axisdriver’ and
check that the plunged boss at the shaft bore points to the front of the
pump head.
Use genuine spare parts only !
WARNING!
Aggressive media residues possible.
On dismantling, repairing or cleaning the pump, protective
glasses and protective clothing must be worn!
NOTICE!
With clean cooling fins, an A4 sheet of paper is sucked onto the
grille on the right housing side and sticks.
Make sure that contact pulleys roll easily on the axis. After remounting the axis with contact
pulley into the driver the spring has to be mounted as shown in Figure 22. Please pay attention
to the alignment of the dent.
Remounting happens in reverse order.
18.3.3 CLEANING THE PUMP HEAD
We recommend that you clean the individual parts with a dry wipe. Solvents should generally not
be used when cleaning, as they may damage the plastic parts. If oil-free compressed air is
present, the parts can be blown out.
18.4 CLEANING OF THE COOLING FINS OF THE COMPRESSOR COOLER
In order to prevent reduction in cooling performance, the cooling fins of the compressor cooler must be
cleaned of dust regularly. To do this, blow compressed air on the right side in the housing into the
ventilation grille.
