4.4 Mounting and connecting
4.4.1 Requirements for mounting:
The following are essential for mounting:
● Gas lines, sample lines, exhaust gas lines
● Power switch, line fuse, power cable
● Equipotential bonding cable
● Communications cable
CAUTION
Do not remove the dummy plug prior to startup
Leave the dummy plugs on the gas inputs until you start up the chromatograph.
Check the correct functioning of the gas lines before you connect them to the
chromatograph!
CAUTION
Destruction of the thermal conductivity detectors
Only use the carrier gas specified in the device documentation! The thermal
conductivity detectors could be destroyed.
Do not operate the thermal conductivity detectors with bridge voltages higher than
those specified in the application data. The bridge voltages must be optimized at
minimum values in order to guarantee a long service life for the thermal conductivity
detectors The maximum bridge power is 70 mW for helium.
Note
Increasing the detection limit
If you are satisfied with a shorter service life for a thermal conductivity detector, you can
increase the maximum bridge power to more than 70 mW for helium.
Before increasing the bridge power, please first contact Siemens AG servicing personnel.
