Figure 2 Design of the portable conditioning and sampling system PSS-10/1
All the components of the gas conditioning system can be easily removed from the portable case. The door of
the case can be opened by moving the toggle-type fasteners on the side and the top to the left.
The installation of a gas cooler and an appropriate diaphragm gas pump will be carried out according to
the maximum flow of gas extracted (see instruction manual for individual components). The possible
combinations are listed in the following table:
The minimum amount of flow is determined by the sample gas pump. Premature damage can be caused to the
pump membrane if less than the minimal total amount of flow is extracted as a result of excess pressure.
All gas coolers are equipped with a Duran glass heat exchanger. Heat exchangers of PVDF or stainless steel are
also available.
The preliminary filter FP-2T (2 μm filter element fineness) installed in front of the gas measuring pump ensures
that the correct amount of solid matter is precipitated.
The sample gas pump is turned off and on automatically by means of an excess temperature contact on the
cooler (+8 °C).
The resulting condensation is continually lead off by means of the SR25.1 peristaltic pump (see Appendix for
individual component instructions).
A preliminary filter, PF2 has been fitted in the condensation hose in between the heat exchanger and peristaltic
pump. This prevents particles in the condensate entering the pump.
The 4/6 mm hose connections for the condensate and measuring leads are located on the right-hand side of
the case (see figure 2 and 3).
The stainless steel sample probe (0.5 m length, 6 mm diameter) and the 3 m sample line (DN 4/6 mm) are
delivered with all models.
The ventilation grids located in the lid and the left-hand side of the case ensure that the equipment is sufficiently
ventilated.

www.mc-techgroup.com PSS-10 | 1.00.02 11
Options
The gas conditioning and sampling system PSS-10/1 consists of standard one gas-measuring outlet terminal. An
additional flow meter (DK800R), with needle valve, can be fitted to this terminal, whereby the adjustment of the
terminals is carried out in accordance with the specified volume flow rate (see 3.).
In order to protect additionally connected analysers against fluid irruption, and increase the operational safety of
the entire system, we recommend that a fluid alarm sensor LA 1S be installed. In such a case, the preliminary
filter FP-2T, which is delivered with all models, will be replaced with the FP-2T-D preliminary filter by the
manufacturer (see appendix). The LA-1.4 electronics is located on the clamp mounting rail in the upper part of
the case. In the event of a fluid irruption, the LA electronics automatically turns off the sample gas pump. The
alarm will be raised by means of a red LED. If the equipment is functioning properly, i.e. no alarm, a green LED
will be on.
The PSS-10/1 can also be equipped with an additional gas measuring inlet terminal (see figure 3, part No.
01G9062 and 01G9063) in order to connect a heated sample line. The existing anti-kink device is only to be used
for heated sample lines in conjunction with the model "C" connection (part No. 03B1012). Mounting instructions
can be found in the Appendix.
The heated sample line, part No. 01B4035, can also be fitted in conjunction with the sample gas probe PSP
4000.
In the event that the heated line is ordered as additional equipment, the necessary temperature controller 701
(part No. 01G9055(a)) will be fitted to enclosure by the manufacturer.
A 3-way ball valve (01G9046) or 5-way ball valve (01G9045) can be fitted to the inlet terminal of the gas
conditioning system in order to calibrate analyser(s) with check gas, or to switch from one sample gas
measurement to another.

11 INSTALLATION INSTRUCTIONS
CAUTION!
Heavy device!
Risk of injury when handling heavy equipment.
Do not lift, move or carry the device without help. A second person is
required to lift, move or carry the device.
NOTE!
When in use, the gas conditioning system case should be placed in an area well
away from any heat emitting sources in order to prevent damage caused by an
accumulation of heat. The air vents in the case must be free at all times.
In order to ensure that the case is safe and stable when being used, it should be
laced on a horizontal surface.
The equipment is to be used in a vertical position only. The perfect functioning of
the separation and drainage procedures will only be guaranteed if the equipment is
used in a vertical position.
When the equipment is being used outside, ample protection against the effects of
direct sunlight and dampness must be provided. In winter, the equipment must
only be used in frost-free areas.
It is recommended that the case be protected using one of the many models
available.
In order to guarantee the operational safety of the gas conditioning system and the
additionally connected analysers, and to avoid false alarms, the gas conditioning
system should not be used at temperatures other than those specified.
It is of great importance that the analysers which have been additionally connected
be used at temperatures well above the specified gas outlet dew point of +5 °C [41
°F]. This prevents the gas in the connector lines from condensing completely.
In the event of the unheated sample gas lines being connected to the gas
conditioning system on a slope, it is not necessary to carry out a preliminary
condensate removal.

16 PSS-10 | 1.00.02 www.mc-techgroup.com
12.2 ELECTRICAL CONNECTIONS
WARNING!
Wrong supply voltage can damage the equipment. When connecting
the equipment, make sure that the supply voltage is identical with the
information provided on the model type plate!
NOTE!
For the erection of power installations with rated voltages up to 1000V,
the requirements of VDE 0100 and relevant standards and
specifications must be observed!
The main circuit is equipped with a fuse corresponding to the nominal
current (over current protection); for electrical details see technical
data.
The PSS-10/1 gas conditioning system is available with either 230 V/50 Hz or with 115 V/60 Hz. A 6.3 A slow-
acting fuse is used on all models as fuse protection. The fuse is located in the power socket of the PSS enclosure.
In the event that a temperature controller is used in conjunction with heated sample lines, the overload
protection level is increased to 10 A.
The electrical connection is carried out by means of a cold appliance plug and 2 m of cable located on the left-
hand side of the case. The cold appliance plug socket is equipped with two-polled main switch.
Option ‘Heated Sample Lines’:
A connector box, as shown in diagram 3, is available for the mains connection when using a heated sample line
with a PT100 temperature sensor, or for the connection of other heated components such as a heated sample
probe or a heated filter.
The maximum length of the heated sample line which can be used is calculated as follows:
max. connection power [W] - power draw of heated components (i e. sample probes) [W]
L(m) = –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
power draw of heated sample line [W/m]

www.mc-techgroup.com PSS-10 | 1.00.02 17
13 COMMISIONING
Observe the facility and process-specific safety measures before commissioning.
Carry out the following steps before initial commissioning:
1. Place the cold appliance plug, which is delivered with the mains supply cable, into the cold appliance plug
socket.
2. Connect the heated sample line (option).
WARNING!
Check the temperature at the temperature controller when operating the
sample gas conditioning unit with a heated sample gas line.
3. Connect the mains plug to the power supply.
4. In case of option temperature controller 701 adjust the required temperature at the controller:
The digital display shows the actual temperature value of the heated line after switching on the
conditioning unit. The controller is adjusted to 0 °C [32 °F] by factory. To change the set temperature press
key
P . The display shows SP and after that it changes to the adjusted set temperature.
Change the value with the arrow keys. After 60 seconds the display switches automatically to the actual
value.
The gas measuring cooler will become operational after approximately 10 minutes. The excess temperature alarm
contact located in the cooler switches the sample gas pump automatically on as soon as the temperature
reaches +8 °C [46.4 °F].
NOTE!
The following minimal gas flow rate has been determined on the basis of
the requirements of the maximum pressure on both sides of the gas
measuring pump N9-KPE:
N 9 KPE approximately 200NL/h air
Premature damage can be caused to the pump membrane if less than
the minimal total amount of flow is extracted as a result of over pressure.
For long-term measurements with a high dust content in the sample gas,
a suitable gas sampling probe must be provided to protect the sample
line from being clogged.

18 PSS-10 | 1.00.02 www.mc-techgroup.com
14 CLOSING DOWN
NOTE!
The area where the gas conditioning unit is placed must remain frost-
free even when the unit is switched off.
No special measures are to be taken in the event of short-term shutdowns of the gas conditioning system.
In the case of long-term shutdowns, for example after a completed series of measurements, it is recommended
to purge the gas conditioning system with fresh air or inert gas. A flushing time of 3 to 5 minutes is sufficient
under normal conditions. Condensate residues must also be removed from the system.
WARNING!
Aggressive condensate is possible.
Wear protective glasses and proper protective clothing!

www.mc-techgroup.com PSS-10 | 1.00.02 19
15 MAINTENANCE
Before the maintenance work is carried out, it is necessary that the specific safety procedures pertaining to the
system and operational process be observed!
WARNING!
Dangerous voltage!
It is necessary to take the equipment off the mains before any assembly,
maintenance or repair work is carried out.
The frequency of the maintenance work depends on the operational process and can therefore only be
determined in each individual case. Maintenance instructions pertaining to individual components can be found
in the instruction manual for individual components.
All parts which might require maintenance work are easily accessible housed in the gas conditioning system. The
following parts might require maintenance work:
The filter element of the preliminary filter FP-2T.
NOTE!
In order to protect downstream analyzers, the wet filter element must
always be replaced in the event of a condensate breakthrough.
The preliminary filter for the peristaltic pump PF2. If the condensate contains particle residue, the preliminary
filter should be replaced at regular intervals. The ‘one-way’ filter is situated in the suction side of the pump
hose and can be easily replaced;
Hoses of the condensate pump SR25.1. These should be checked every six months and, if necessary,
replaced (consult the instruction manual in the Appendix);
Diaphragm of the sample gas pump N9KPE. These should be checked every six months and, if necessary,
replaced;
