EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. C 103
Igniting the flame
12. Flame ignition is automatic.
Image 48: Igniting the flame
Depending on the number of ignition attempts, flame ignition
can take up to 10 minutes.
On initial commissioning of the gas analyzers, it may occur that,
depending on the position of the combustion gas line, there is
not sufficient combustion gas available to ignite the flame at
first. In this case, you need to go to the ‘Fidas Restart‘ menu to
restart the ignition of the flame, see Fidas24 – Standby /
Restart on page 104.
The flame temperature is also displayed in this menu. The flame
is considered to be ‘on’ when the flame temperature is at least
30 °C higher than the detector temperature.
With the ignition of the flame, the actual commissioning of the
gas analyzers is ended.
Note
Unused sample gas lines and sampling probes may continue to
emit hydrocarbons for an extended period after initial operation.
As a result, it can take much longer for the measured value drift
to reach an acceptable value.
Recommissioning the gas analyzer
Risk of burns
Risk of burns on the hot (> 70 °C) cover of the heated sample
gas connection.
• Do not touch the cover of the heated sample gas
Heater damage
Damage to the detector heater and the heated sample gas
connection due to an improper connection.
• Attach or disconnect the connector 30 of the power supply
for heating the detector and the heated sample gas
connection only if the gas analyzer is de-energized.
1. Feed in instrument air and combustion air and purge the gas
analyzer for at least 20 minutes
2. Check the leak tightness of the combustion gas supply line,
see Check the integrity of combustion gas path on
page 105.
3. Turn on the gas analyzer power supply.
4. Power-up the combustion gas supply and check the
combustion gas pressure.
5. Turn on the sample gas supply.
