Fidas24: Gas analyzer start-up
Gas analyzer start-up
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.
If the analyzer module is not installed in the central unit, switch on the
separately installed 24 V DC supply of the analyzer module.
2 The following events will occur after the power supply is turned on:
1 The three "Power", "Maint" and "Error" LEDs light up.
2 The different booting phases are displayed on the screen. Also the
software version is displayed.
3 After a brief time the screen switches to measurement mode.
4 The softkey
STATUS
MESSAGE
appears on the screen. This indicates the possibil-
ity of a temperature or flow problem during the warm-up phase. By
pressing the softkey the user can recall the status message sum-
mary and view status message details.
3 Select the Controller measured values menu item:
MENU → Diagnostics/Information → Module-specific →
Controller Measured Values
Amongst other things, the controlling variables of the temperature reg-
ulator are displayed in this menu option:
T-Re.D Detector temperature
T-Re.E Temperature of the heated 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 dis-
played in the Controller measured values menu item; the pressures
of the supply gases are set by means of the controlled variables:
MGE Pressure at the sample gas nozzle
MGA Pressure in the combustion chamber (outlet)
C-Air Combustion air
C-Gas Combustion gas (H
2
or H
2
/He mixture)
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 is in pro-
gress 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 operator has not pressed a key in menu mode in the
last five minutes.
