1.3 Main instructions for operation
Start-up
 Ensure gas tightness; check the filters, valves etc.
 Ensure correct supply of operation gases (specifications →P. 194, §16.6).
 After start-up wait until the warm-up period has elapsed (approx. 2 hours).
 Then calibrate the device (→P. 145, §12).
Operational state
 Observe the LED displays:
– “Alarm” (red) = measured value is/was outside the threshold values
– “Fault” (yellow) = malfunction in the measuring system; the measured values are
not valid
– “Service” (yellow) = action by user required (service requirement)
– “OK” (green) = EuroFID measuring system is ready for operation; meas. value is valid
 Observe the messages at the bottom of the display.
If “Alarm” is displayed
 Check the current measured value. Assess the situation.
 Take appropriate action to deal with this situation during operation.
 If the alarm message is self-locking: Cancel the alarm message (“Reset” →P. 130,
§11.13) as soon as the measured value is inside the threshold value.
In hazardous situations
 Switch off the emergency off switch/main switch of the higher-level system.
Maintenance
 Calibrate the device regularly (→P. 145, §12).
 Clean the integrated sample gas filter regularly (every 2 months →P. 162, §14.4).
 If the EuroFID is used as a gas detector: Check the function of the alarms regularly.
Shutdown
 Secure/deactivate connected systems (→P. 156, §13.1.1).
 Prevent condensation in the measuring system. To this purpose purge the sample gas
path with dry gas. The simplest solution: Use the “Zero point test” function (→P. 153,
§12.6.1).
 Let the analyzer unit cool before starting work on the interior of the device (risk of burns).
Fragile sampling probe
Only valid for “inline” and “industrial housing” type analyzer units.
The mains switch of the EuroFID is on the rear of the operating unit (→P. 59,
Fig. 18).
NOTICE:
 Only open the sample gas filter when the “Filter change” status is activated
(procedure →P. 163, §14.4.2).
Otherwise dust-laden ambient air can enter the measuring system. Soiling
which occurs as a result can render the measuring system useless.
 Observe the permissible lifting points (→P. 42, §4.3.1).
Do not use the sampling probe as a lifting point.
Do not subject the sampling probe to mechanical loads.
This could cause breakage of the glass vacuum tube.

Important Information
1.4.3 Restrictions of use
Explosion protection
The EuroFID is not suitable for operation in potentially explosive atmospheres. Operation in
potentially explosive atmospheres requires additional safety equipment.
Properties of the sample gas
The EuroFID should never be used
– For measuring operationally explosive gas compounds
– For sample gas compounds which form an explosive mixture with air.
The sample gas should not contain substances which could chemically corrode the
components in contact with the sample gas (materials →P. 195, §16.7). Such
substances should also not be formed during combustion of the sample gas (in the FID
flame).
The sample gas should not contain any gas components which could condense in the
measuring system (temperature in the measuring system →P. 117, §11.10).
No solids should be formed during gas combustion.Solids in the gas path could
obstruct the measuring system.
If the “inline” type analyzer unit is installed: Do not exceed the following temperature
limits:
– Sample gas temperature at the gas inlet of the sensor tube: 350 °C (660 °F) max.
– Dewpoint temperature of the sample gas: 200 °C (390 °F) max.
Influence of oxygen (O2) and sulphur dioxide (SO2) in the sample gas
●If the O2concentration in the sample gas fluctuates, the measured values can be
corrupted. The EuroFID is set at the works so that the measurement error is not greater
than 4 % of the measuring range end value.
●If the following conditions apply at the same time in the sample gas:
–SO
2concentration > 50 mg/m3
–O
2concentration < 15 percent by volume
then the measurement error in the measuring range tested for suitability (15 mg/m3C)
is higher than 4 % if H2is used as fuel gas. In such cases an H2-He mixture must be
used as a fuel gas for measurement in the validity range of the suitability test
(specification →P. 195, §16.6.2).
If the EuroFID is used for measuring combustible gases or for sample gases
which can form a combustible gas mixture with air, there is a potential risk of
explosion in the event of a defect in the internal gas paths (leakage). The gas
could ignite when it comes into contact with hot surfaces or the FID flame.
For such applications:
 Check which regulations and laws apply at the installation site in such
cases.
 Check whether additional safety equipment has to be installed (e.g.
housing enclosure and purging).
The EuroFID is configured and adjusted accordingly for such applications at
the manufacturer's works. For all other applications, H2is preferable as a
fuel gas.

Product Description
2.1 Measuring principle
Fig. 1 Measuring principle
The EuroFID uses a flame ionization detector (FID) for measuring the hydrocarbons. A
hydrogen flame supplied by fuel gas and combustion air burns in the FID. The sample gas
is routed into this flame. The hydrocarbons contained in the sample gas are split; the
produced hydrocarbon fragments are ionized. A stream of ions forms in the electric field
and this electrical stream is measured.
The measuring signal is proportional to the number of the listed, non-oxidized hydrocarbon
atoms. Hydrocarbon atoms which are already oxidized are only partially detected.CO and
CO2are ineffective.
The quantitative correlations between the measurement signal and the hydrocarbon
concentration in the sample gas is determined by performing reference measurements
with calibration gases which do not contain any hydrocarbons (zero gas) or of which the
hydrocarbon concentration is known exactly (calibration gas – e.g. 80 ppm propane in air).
2.2 Measuring method
Instrument air
The EuroFID requires hydrocarbon-free instrument air for operation. The instrument air is
used in the EuroFID for the following purposes:
– As induction air for the ejector pump
– As combustion air for the FID
– As control air for regulation of the sample gas flow to the FID
– As zero gas for calibration
Heated sensor block
To prevent condensation in the sample gas path, the parts in contact with the sample gas
(sample gas filter, ejector, sample gas capillaries, bypass orifice plate, sensor) are
accommodated in a heated, thermostatically controlled “sensor block”. The constant
temperature is the pre-requisite for a constant sample gas flow to the FID. The temperature
in the sensor block depends on the individual measurement application (90 … 200 °C).
