4.5 Installation and activation of the
Cong Prima 2M with the SGA 003 system
!
In this configuration, the analyzer and the SGA 003 are delivered already assembled.
The analyzer (5), pressure transmitter (28), and the heating element (21) are connected to
the explosion-proof terminal boxes (16, 17, and 18). All of the SGA’s connection seals are
tested to a pressure of 160 bar at the factory.
Complete the installation of the SGA 003 as follows:
Affix the SGA 003 to a vertical wall of purpose-built vertical stand using four M( bolts (not
included in delivery).
Complete the electrical installation of the SGA 003 in accordance with Appendix K.
Ground the SGA 003. To do this, connect the SGA’s grounding terminal with the ground bus
at the installation site. This requires an insulated copper conductor with a cross-section of at
least 1.5mm
2
(or 4mm
2
for an copper conductor that is not insulated).
Connect the gas outlets (13 and 14) to a collector for sample release to the atmosphere.
Close the ball valve at position 19.
Close the flow control regulator on the rotameters (9 and11)
Close the pressure valves (3 and10). To do this, turn the regulator on the valve all the way
counterclockwise.
Set the process switch (4) to the desired position.
For “W the dew point is measured at operating pressure.
For “HC” the dew point is measured at reduced pressure.
Complete the electrical installation of the heating unit (21)
Open the SGA’s gas delivery shutoff valve (1) gradually and evenly.
Refer to the manometer (8) to monitor the increasing pressure in the system.
Use the by-pass line rotameter to set the gas flow rate at from 6 – 10 Nl/min.
If the process switch (4) is set to “W”, fully open the pressure valve by turning the knob on
the valve all the way clockwise.
Use the rotameter (9) to set a sample gas flow rate of from 0.2 – 0.3 Nl/min.
If the process switch (4) is set to “HC”, the operator can use the pressure regulator valve (3)
to adjust the sample gas pressure as desired.
The current pressure in the measurement chamber (5) is displayed by the manometer (6).
When the pressure regulator valve is fully open, the sample-gas flow rate is in the
0.2 – 0.3 Nl/min range.
Connect the power supply.
Important!
If the composition of the gas has very little liquid aerosols and accompanying substances or
has already been filtered, outflow through the bypass outlet may be dispensed with.
For superior gas convection and a more active dew point measurement, the manufacturer
recommends a through-flow in the bypass line of around 1Nl/min.
