Page 9: Technical Data Of The Analyser
Note! In order to supply sample gas to the analyser (e.g. from a WITT gas mixer or a gas mixture receiver) it is necessary to install a suitable gas line between the equipment where the gas sample is taken from and the corresponding analysis gas inlet port of the gas analyser. The installation of a suitable gas pipeline has to be performed by the customer. -

Page 19: Warm Up Screen
0.30 H2/N2 After switching on and warming up the MFA 9000 shows the operation screen. Mainly it provides the user with the measured gas concentration. The first line gives the user status information. E.g. in occurrence of process alarms or a system error an appropriate indicator is shown. -
Page 20: Top Level Main Menu
Within this menu the operator can select where to go from here. If the item “Opera- tion” is selected (as shown) the MFA 9000 will return to the Operation screen by pressing <EN- TER> or <UP>. To get access to a submenu, first select the appropriate item and press <ENTER>. -
Page 21: Gain Gas Concentration
The current loop is refreshed. If the operator uses the option “YES” in the “Gain Calibration?” menu this starts the gain calibration procedure. : +49 (0)2302 89010 WITT-GASETECHNIK GmbH & Co KG Salinger Feld 4-8 www.wittgas.com Gas Safety- & Control Equipment... -
Page 22: Gain Calibration
------------ P001 The entire accessible individual configuration of the MFA 9000 is stored in about 200 Parameters. In the Parameter menu all configuration and actual measuring can be retrieved from the instru- ment. This may help to diagnose malfunction and mal settings. -
Page 23: Errors
Reset All? NO/YES The MFA 9000 continuously checks the internal electronic parts as well as the connected sensor against plausible values. If one or more of the actual states fit to the predefined alarm mask a sys- tem alarm is triggered and an error occurs. This is indicated in the first Display line by “Er”. In this case the system alarm indicator is flashing. -

Page 26: Measuring Gas Setup
In the second line the binary gas to be measured may be altered. The stored underlying list of dif- ferent measuring and carrier gases depends on the ordered configuration of the MFA 9000 and may contain up to 16 binary gas mixtures. -
Page 27: Response Time Setup
In the third line the temporal response of the instrument can be adjusted. The MFA 9000 has a build in exponential smoothing filter, with an adjustable T90 response time. It can be used to reduce fast variations in the reading due to fluctuation in the gas concentrations within the process as well as for reducing noise. -

Page 37: Expert Setup
Within the expert level the user has the possibility to set or change all parameters as well as reset the MFA 9000 to its default parameters. Also within the expert level it is possible to change the codes to access the operator and the expert level. Furthermore the subsequent equipment can be tested for correct settings and connection by simulating alarm states and feed analog outputs. -
Page 38: Access Modes
The Operation Mode “3.00000” is a safe mode. Each alteration in this mode requires the man- ual input of the actual Operator Code. The Operation Mode “2.00000” is the Multi Gas Mode. It is only available when the MFA 9000 is ordered with this option. : +49 (0)2302 89010 WITT-GASETECHNIK GmbH &... -
