Safety extra low voltage is a small electrical voltage
that provides particular protection against electrical
shock compared to circuits of higher voltage thanks
to its small magnitude and insulation.
Devices operating on SELV that do not generate hig-
her voltages themselves are categorized as Class III
appliances in accordance with DIN EN 61140 (VDE
0140-1).
Always observe the full safety instructions (see cross references).

1.1.1Safety instructions
NOTICE: Observe the reaction time of the FID during a hydrogen supply
failure
During a hydrogen supply failure, the flame of the FID keeps burning for some
time until it goes out completely.
It is possible that the measured value of the FID does not correspond to the
true value during this time.
The reaction time can be up to 50 seconds depending on the version of the
equipment.

In order to monitor for a hydrogen supply failure, monitor the inlet pressure
of the fuel gas using a pressure controller, which emits an electric signal at
a certain minimum pressure (e.g. < 3 bar).

Important information
NOTICE: Responsibility for the safety of a system
The person setting the system up is responsible for the safety of the system in
which the device is integrated.
The EUROFID3010 Inline UEG fulfills the minimum requirements of DIN EN 50271:2011
for detecting and measuring combustible gases and vapors.
Additional requirements for compliance with a safety integrity level (SIL1) in the EN 61508
series are not fulfilled.
▸
The temperature of the heated sensor block must be 25°C below the classification temperature (TC) and may not be set above 195°C.
▸
The cutout temperature of the overtemperature shutoff must be checked annually in
accordance with the operating instructions.
▸
Malfunctions and alarms are to be reported (as a group message as necessary) visually
and acoustically to a continuously staffed location.
▸
To ensure reliable alerting, the “Measured value valid” and “Service/Maintenance
switch” contacts should also always be monitored along with the “ALARM” relay contact.
▸
The signal “Service/maintenance switch” must be forwarded to a higher-ranking level
(e.g. control center).
▸
Execute the contact of the service/maintenance switch as an N/C contact (closed
current principle).
▸
Following a restart, a gas calibration must be carried out at the zero or end point.
▸
After replacing the test gas cylinder, enter the new test gas concentration in the
“Calibration Gas Value” menu.
▸
For safety-relevant measurement, only the approved response factors may be used.
▸
When monitoring the lower explosive limit (LEL), the operating unit with the V2 terminal
module must be used.
The exhaust gas from the exhaust outlet may not be returned to the process.
▸
The analog measured value output may not be used for safety-relevant monitoring.
▸
A failure of operating voltage is to be treated as an alarm.
▸
Before using the device in a gas detection system, make sure the response times are
short enough to ensure that the warning triggered by the device occurs quickly enough
to avoid unsafe situations. It may be necessary to set the alarm thresholds considerably
lower than the safety-relevant threshold.
▸
When the device is used as intended to warn against a potentially explosive
atmosphere, use the currently recognized local value for the LEL.
▸
The trigger delay for the alarm thresholds must be set to 0.
▸
Transmission errors between the analysis component and the control unit can cause
delays up to 2 seconds before a malfunction message is triggered.

WARNING: Risk of explosion in potentially explosive atmospheres
▸
Do not use the EuroFID3010 Inline UEG in areas subject to explosion
hazards.
● EuroFID3010 Inline UEG is intended for indoor operation.
● The analyzer unit can be used outdoors if a weatherproof cover (option) has been
installed.
● This product was designed for specific applications in large-scale fixed installations
according to Article 2 (4) e, RoHS 2011/65/EU and accordingly may be used only in
such installations. The product is neither suited nor authorized for use outside these
installations; SICK can therefore not accept any warranty or liability whatsoever for such
use.
These operating instructions have been submitted to and certified by DEKRA
EXAM and must be carefully observed.
When used as a gas detector, make sure that the operating conditions stated

1.5Additional documents
● The EuroFID3010 Inline UEG is supplied with a test log.
The EuroFID3010 Inline UEG gas analyzer is a gas detector for continuous measurement
and monitoring of LEL concentrations of combustible gases and vapors in processes in
accordance with DIN EN 60079-29-1.
● Measuring range: 0-100% LEL.
A relay for threshold monitoring may be activated depending on the measured gas
concentration and the alarm threshold settings. (→ p. 57, §7.3).
There is also an extractive version of the EuroFID3010 gas analyzer, observe
the special additional EuroFID3010 Extractive UEG Operating Instructions.
2.1.1Response time
The response time for activating the alarm contact is approx. 2-3 seconds, depending on
the sample gas flow.
WARNING: Delayed reaction when soiled
The response time is longer if the sample gas filter is soiled.
▸
Check the sample gas filter regularly (→ p. 132, § 14.3.1.)
The EuroFID3010 Inline UEG uses a flame ionization detector (FID) to measure
hydrocarbons. A hydrogen flame burns in an electric field in the FID, fed by fuel gas and
combustion air. The sample gas is routed into this flame. The hydrocarbons contained in
the sample gas are split, and the resulting CH fragments are ionized. A stream of ions forms
in the electric field and this electrical current is measured.

▸
Leak detection spray, sensor for combustible gases.
NOTICE:
Contaminated operating gases can falsify the measured values and damage
the analyzer unit.
▸
Make sure that the gas lines are clean:
– Free of particles (dust, shavings)
– Free of hydrocarbons (grease, oil, solvents).
NOTICE: Observe the reaction time of the FID during a hydrogen supply
failure
During a hydrogen supply failure, the flame of the FID keeps burning for some
time until it goes out completely.
It is possible that the measured value of the FID does not correspond to the
true value during this time.
The reaction time can be up to 50 seconds depending on the version of the
equipment.
▸
In order to monitor for a hydrogen supply failure, monitor the inlet pressure
of the fuel gas using a pressure controller, which emits an electric signal at
a certain minimum pressure (e.g. < 3 bar).
3.4.3Connecting instrument air
The EuroFID3010 Inline UEG requires hydrocarbon-free instrument air to operate
(Specifications → p. 166, §16.8.1).
Instrument air is used for the following purposes:
– As propellant air for the ejector pump
–Sample gas dilution
–As combustion air
–As control air
– As zero gas for calibration
▸
Install a continuous supply of instrument air at the gas connection labeled “Instr.air.”
Install a continuous supply of fuel gas at the gas connection labeled “Fuel gas.”
WARNING: Risk of explosion if fuel gas line leaks.
The fuel gas is H
A leak in the fuel gas line may lead to an explosion.
▸
Implement safety precautions to prevent explosion.
– Install a volume flow limiter in the fuel gas supply line.
– Install a leak detector on the fuel gas supply line to emit a signal when
H
is discharged.

▸
Monitor the cylinder pressure of the fuel gas with a pressure monitor which emits an
electrical signal below a certain minimum pressure (e.g. < 3 bar).
Connect the signal from the pressure monitor to the digital input labeled “Fault Gas Supply”
(→ p. 60, §7.4).
3.4.5Connecting the calibration gas (“span gas”)
▸
Install a continuous supply of calibration gas to the gas connection labeled “Calibr.gas.”
▸
Recommendation: Monitor the cylinder pressure of the calibration gas with a pressure
monitor which emits an electric signal at a certain minimum pressure (e.g. < 10 bar).
Connect the signal from the pressure monitor to the digital input labeled “Fault Gas Supply”
(→ p. 60, §7.4).

3.4.6Information on connecting a cylinder pressure monitor
A pressure monitor must be connected to terminals X20.13+X20.14 of the V2 terminal
module. When two pressure monitors are used, their contacts must be connected in series
and can only be processed as a composite signal.
