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

Controller values
menu item:
Maintenance Diagnosis Device Status
Analyzer Status Controller Values
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
2
or
H
2
/He mixture). Adjust the pressure to the value specified in the
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
2
or H
2
/He mixture)
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
pressure.
The gas analyzer automatically reverts to the measurement mode to
display values if the user has not pressed a key in menu mode in the
last five minutes.
