Fidas24: Start-up of the Gas Analyzer
Switch on the power supply, heating-up phase, feed in supply
gases
1 Switch on the power supply of the gas analyzer and the heaters of
the Fidas24.
2 The name of the gas analyzer and the number of the software version
are shown in the display while booting.
After the start-up phase has ended, the display switches over to the
measured value display.
3 Select the Controller values menu item:
Maintenance
Analyzer Status
The actual values and setpoints and the controlled variables of the
internal temperature regulators are displayed in this menu option:
T-Re.D Detector temperature
T-Re.E Temperature of the heated sample gas connection
T-Re.K Temperature of the internal combustion air preparation
TR.VV1 Temperature of the preamplifier
The temperature values slowly increase after the power supply is
switched on.
4 Feed in instrument air, combustion air and combustion gas (H
H /He mixture). Adjust the pressure to the value specified in the
2
analyzer data sheet with the corresponding external pressure
regulator.
5 The controlled variables of the internal pressure regulator are also
displayed in the Controller values menu option:
C-Air Combustion air pressure
C-Gas Combustible gas pressure (H
MGE Pressure at the sample gas nozzle
MGA Pressure in the combustion chamber (outlet)
The pressures of the supply gases are set by means of the controlled
variables. To begin with, any values can be displayed for the
controlled variables. The values are updated for the first time approx.
10 s after selecting the menu option and then approx. every 10 s. The
pressure control continues to run in the background. It may take
some time to set the pressures depending on the setting of the inlet
