1 Introduction
This software manual describes step by step how to operate successfully with the ½ 19"
and 19" MLT analyzer module and analyzer of the
NGA 2000 Series.
Chapter two shows the structure of the MLT software menus. Chapter three describes the
display and the keyboard of the analyzer. Chapter four describes the basic controls with
detailed illustrations. So you can easily compare the actual display of the analyzer module
with the illustrations of the manual.
Chapter five describes the expert configurations of the analyzer module and of the Input/
Output Modules (I/O modules). Chapter six describes the system configuration. The layout
of both chapters is not as detailed as in chapter four. Normally, the way to a certain menu
of the MLT software is described with the software catchwords you have to press to reach
this menu. You will find the illustration of the corresponding LCD screen at the end of the
catchword listing. After that you can read the meaning of the functions and variables of
each expert or system configuration menu.
Some contents of the expert configurations are not important for each customer. It depends
on the configuration of your NGA 2000 system, relative to the following components:
¨ Control Module
¨ Analyzer Module
¨ Input/Output Modules
CM
AM
I/O's (SIO = Standard I/O, DIO = Digital I/O,
System Auto Calibration I/O, Analog Output with 3 Alarms I/O,
Auto Calibration I/O)
You can distinguish the following system units and SIO/DIO configurations:

SIO/DIO-Configuration
MLT analyzer module (AM):
Þ 1 local SIO and 1 local DIO can be
installed in the MLT analyzer
module
Þ SIO and DIO can be configured
for the channels of the analyzer
module only
· without front panel,
i.e. without control unit
· can be combined with a platform,
an MLT analyzer, a TFID analyzer
or a customer developed control
unit
* 5.1.18
p. 5-67
Platform (CM Software):
Þ 1 SIO and up to 4 DIO's can be
installed in the platform (CM I/O)
Þ SIO and DIO can be configured
for all channels combined with the
platform
· Control unit with front panel
· Without measurement channels
* 5.2
p. 5-83
MLT analyzer (CM and MLT AM
software):
Þ 1 SIO and 1 DIO can be installed

MLT analyzer
· Analyzer with front panel
· CM and AM software in the same
analyzer,
* 5.2
p. 5-83
i.e. all functions of the control unit
and of the AM are combined in one

3 Startup and Operation, General Notes and Main Menu
3.1 Starting and Initializing
After switching on the MLT analyzer or analyzer module (in a platform or part of a NGA
network), the initialization procedure will be performed. A self control of the analyzer
modules or the analyzer is running. You can see a sequence of several displays. They
show the status of initialization, revision notes of the MLT software and the
tag:

NGA-2000 Control Module/Version 3.2.1
Initializing Network
Initializing network interface
LCDReset
Abort
F1
F2
F3
F4
F5
If you press the F1 key during the initializing, you will reset the LCD brightness and
contrast to factory settings (see also section 7). Pressing the F3 key will abort the network
initializing. Then you will have no connection to any analyzer module. Only the menus of
the platform will be available.
At the end of the initializing procedure you can see the single component display of
channel one (see illustration on next page). It is the origin to all the other channels, menus
and submenus.
The instructions of the basic controls (chapter four) are all beginning with the single com-
ponent display. The actual display might differ from the shown one because the customer
can configure it according to his requirements (see section 5.1.8 p. 5-49 and section 7).

3.2 Display and Function
The LCD screen shows all measurement values of the analyzer and all customer
instructions. You can operate with five function keys, four arrow keys (cursors) and the
enter key. The function of each key depends on:
¨ the type of analyzer/analyzer module used
¨ the optional auxiliary modules (e.g. I/O boards) used
¨ the individual menu displayed
In case of power failure all customer specific module parameters are saved by a battery-
powered buffer.
3.3 "TAG" and Operating Keys
At the top left of each menu page you will find the tag of the current channel.
Typical tags:
¨ MLT/CH1/R1: MLT Analyzer or Analyzer Module / CHannel 1 / Range 1
¨ TFID-R1:
Thermo FID Analyzer or Analyzer Module - Range 1
In this manual you will find normally "TAG" as general name. But in the specific MLT
menu pages you will find "MLT".

4 Basic Controls and Analyzer Module Calibration
In the chapter "Basic Controls and Analyzer Module Calibration" the most important mea-
surement and calibration functions of your MLT analyzer or analyzer module are described.
All steps are figured with detailed illustrations and operation instructions. In the left column
you can see display and keyboard of the NGA front panel. The keys you have to press are
illustrated in black. In the right column you can read the instructions and notes. All
instructions will begin with any single component display and will end with the correspond-
ing single component display after the setups are done. So you can easily compare the
actual display of the analyzer or analyzer module with the illustrations of the manual.
Example: You want to change from the single component display of channel 1(CO2) to
the single component display of channel 2 (CO).
· Picture one shows the starting situation: single component display of CO2.
· Picture two shows the result you get if you press the F4 key (Channel):
single component display of CO.

Lines of variables "Max. zero calibration deviation" / "Max. span calibration deviation":
The deviation between two zero or span gas concentrations will be determined during the
stability time of the calibration procedure (see menu "Calibration Procedure Setup"
p. 5-9/10). The maximum calibration deviation is the deviation tolerance expressed as
percentage of the current end of range value. The calibration procedure will only be
possible within this range.
If you choose a very small deviation tolerance, perhaps the calculated deviation is out of
range during the whole calibration procedure and the calibration will run into time out. If
you choose a very large deviation tolerance, the calibration will also be done in ranges
with a little stability.
Value is usually: 10% or 20%
Line of variables "Check deviation":
¨ Enabled: The stability and tolerance control during the calibration procedure will be
based on the values of the menu "Tolerances".
¨ Dis abled: The calibration procedure is running without stability and tolerance control.
Any Calibration will be accepted.
Example:
¨ End of range:
¨ Max. calibration deviation:
¨ Desired value:
¨ Display:

¨ Deviation:

¨ Result:

Calibration will be canceled !
Potential solutions:
¨ Adjust 100% in the line "Max. zero calibration deviation"
resp. "Max. span calibration deviation"
or
select "Disabled" in the line "Check deviation".
¨ Result: Any Calibration will be accepted!

Lines of variables "Purge time" / "Procedure times-out after" and
"Stability time" / "Averaging time" – Informations about the calibration procedures setup:
The measurement signal should be stable in a certain range before zeroing and spanning.
Therefore the analyzer cell should be purged enough with zero gas or span gas before
calibration. Then, after the purge time, the stability time is running. During the stability time
the average over two signals will be calculated. The averaging time determines the time
difference between these two signals.

If the deviation of the two values is less then the allowed maximum calibration deviation
(see menu "Tolerances", p. 5-7/8), the calibration may start. If not, the stability control is
starting again until a stable measurement is possible. The time in the line "Procedure
times-out after" is the limit for the whole procedure.

Line of variables "Analog output during calibration":
Here, you can determine if you want to hold the analog output and the limits of a local SIO
in the MLT analyzer module during calibration. The set-ups for a platform or MLT analyzer
SIO have to be done in the menu "Analog Outputs" (see 5.2.1 p. 5-87).
¨ Tracking: The analog output signal is following to the signal during the whole calibra-
tion procedure.
¨ Holding: During the whole calibration procedure the analog output signal is fixed to the
last signal before calibration. This adjustment may be used for instance to control limits
with the analog output.

In the menu "Cross Interference Compensation" you can calculate the influence of other
components to the result of the analyt component. You can take maximum three
interference components for each channel of the MLT analyzer. It is not possible to
calculate the cross interference compensation for signals of auxiliary modules!
If you want to calculate the compensation for other channels of an MLT analyzer or
analyzer module, you have to press the F3 key.
Conditions:
¨ You only have to use pure gases or gases in inert atmosphere (e.g. CH4 in N2) for all
components that you need to calculate the compensation. Do not use mixed gases!
¨ You have to calibrate all channels you need to calculate the interference compensation.
Besides, all channels must be part of the same MLT analyzer or analyzer module.
Calculation of the Cross Interference Compensation:
1) In the line "Compensation is" you have to select "Disabled". If you select "Enabled" the
result will be influenced by earlier values.
2) In the line "Selected interference component" you have to select the number of the
current interference component.
3) Press the 8 -key or the ® -key in the line "Choose interference source channel..." to
change to the submenu "Channels" (illustration see next page):
· Select the line you want with the ¯ -key or the • -key.
· Choose the interference source channel with the 8 -key or the ® -key: The display
will go back to the menu "Cross Interference Compensation" automatically. The tag of
the interference component will appear in one of the last three lines in the menu. The
position depends on the number selected in the line "Selected interference component".

In the menu "Linearization" and its submenus you can set up and start the calculation to
linearize one channel of an MLT analyzer or analyzer module. With the F3 key you can
change to the other channels. With the F5 key (Info...) you can change to the submenu
"Linearization Info", where you will find the results and some parameters of linearization.
Background:
The optical absorption of a gas as a function of its concentration is not linear in the whole
range. Therefore the result of the analyzer has to be linearized. You can linearize manual
or semi-automatically. In this chapter the manual linearization is described. If you want to
linearize automatically, contact your customer service, please.

Conditions:
¨ Before you start the linearization you have to calibrate the largest range of the channel
(usually range 4) with zero gas and span gas.
¨ You have to record a raw values/setpoint values table to linearize a channel. You need
minimum 6 raw values and their corresponding setpoint values: zero, end of range and
4 intermediate values. You should take 10 to 15 values (maximum: 30) to improve the
precision of the linearization curve.
Realize the linearization:
1) Dis able the linearization:
· Before you record the linearization values you have to disable the current linearization
to avoid the influence from the old values to the calculation of the new curve.
· Change to the line "Linearizer is" with the • -key or the ¯ -key.
· Press the 8 -key or the ® -key and select "Disabled" with the • -key or the ¯ -key.
· Confirm your adjustment with the 8 -key.
2) Zero and s pan gas calibration:
· Calibrate the largest range (usually: range 4) with zero and span gas.
· The method is described in 4.5 p. 4-39 and 4.6 p. 4-43 or in 5.1.1 p. 5-15 to 5-17.
3) Recording the raw values /s etpoint values table:
· If you have a defined gas flow, you can read each raw value in any menu display at
the top right or in the single component display.
· Example:
You have got the following values for the NO-Channel of the analyzer:

Programming ( + Cons ider the example p. 5-41 to 5-43 !):
1) Dis able PLC:
· Before you will begin with the programming you have to disable the PLC function in
the line "PLC is" to avoid starting the program while you are writing it.
2) Put in the program:
· Press the 8 -key or the ® -key in the line "Programming..." to change to the sub-
menu, where you can put in your program step by step (+ See example p. 5-42).
· A program is composed of single commands (e.g. Selecting a gas valve), which have
to be connected logically (e.g. OR-Operator). You have to put in a certain code in
every program line for each operator and each command (operand).
· You have to set every operator in the line before the commands that shall be
combined. If an intermediate result is not used in the process directly, you have to
delete the result buffer ("CLEAR"). So, you can avoid errors of the following logical
operations. Each program must end with the operator "-7" ("END of the program").
3) Enable PLC:
· You have to select "Enabled" in the line "PLC is" in the menu "Programmable Logic
Control" to start the program.
4) Controlling of the res ults :
· Press the 8 -key or the ® -key in the line "Results..." of the menu "Programmable
Logic Control" to change to the submenu "PLC Outputs", where you can control the
output status.

Example for PLC Programming:
¨ You have three channels in your analyzer: CO, SO2 and O2.
¨ You want to write a program for the zero and span gas calibration.
¨ The valve gear is:
Sample
CO/SO2/O2
CO/SO2
O2
So you have the following zero and span gas for each gas component:
Channel:
CO
SO2
O2
CO/SO2
O2
Zero gas:
O2
O2
Span gas: CO/SO2 CO/SO2
So you have the following logical combination of the valves:
O2 Valve
CO/SO Valve

Zero-Cal. Channel 1
Zero-Cal. Channel 2
Span-Cal. Channel 3
Span Cal. Channel 1
Span Cal. Channel 2
Zero Cal. Channel 3

In the menu "Programmable Calculator" you can start the calculation with variables of the
MLT analyzer or analyzer module selected, e.g. conversion of concentrations from ppm to
mg/m3. You have four memory places to calculate results. The required program and
further conditions have to be set up in several submenus. The calculation with values of
auxiliary modules is not possible!
Set up parameters:
¨ Select the line of variables or any menu line with the ¯ -key or the • -key.
¨ Select the variable or change to the submenu with the 8 -key or the ® -key.
¨ Select "Enabled" or "Disabled" in the line "Calculator is" with the • -key or the ¯ -key.
¨ Confirm the parameter selected with the 8 -key or
cancel and go back to the last value with the F2 key.
Programming and s tarting of the calculator (+ Consider the example p. 5-47/48 !):
1) Dis able the calculator:
· Before you will begin with the programming, you have to select "Disabled" in the line
"Calculator is" to avoid starting calculation while you are writing the program.
2) Putting in the program:
· Press the 8 -key or the ® -key in the line "Programming..." to change to the sub-
menu "Program", where you can put in your program step by step.
· A program of a calculator consists of operands like concentration or flow and of
operators like the addition command. You have to put in a certain code in each
program line for each operator and each variable or constant.

· You have to set each operator in the line above the corresponding variable. After
each calculating step you have to store the intermediate result and to delete the
memory before you will continue with the next step. Each program must end with the
command "End of program".
3) Putting in the cons tants :
· Press the 8 -key or the ® -key in the line "Constants..." of the menu "Programmable
Calculator" to change to the corresponding submenu, where you can define maximum
four constants, e.g. conversion constant from ppm to mg/m3.
4) Determination of the units:
· Press the 8 -key or the ® -key in the line "Units..." of the menu "Programmable
Calculator" to change to the submenu "Calculator Result Units" to determine in which
unit the calculator's result shall be displayed, e.g. ppm, mg/Nm3, Vol.% and so on.
· Note: This step can also be changed after the program is still running.
5) Scaling
· Via the line "Scaling..." of the menu "Programmable Calculator" you can change to a
submenu, where you can determine the minimum and maximum for each result. This
will be necessary, if you want to show the calculator's result in the single component
display. The minimum/maximum values are the limits of the bargraphs.
6) Starting the program:
· Select "Enabled" in the line "Calculator is" of the menu "Programmable Calculator".
7) Check the res ults :
· The results of each calculator will be displayed in the last four lines of the menu
"Programmable Calculator".
Example for the calculation with a program:
You want to calculate the whole content of NOx as NO2 in mg/m3 from the concentrations
of NO in ppm (Channel 1) and of NO2 in ppm (Channel 2). So you have to add the single
concentrations and then to multiply with a constant:
(ppm NO + ppm NO2) · "conversion constant (here: 2,05 mg/ml)" = NOx as mg/m3 NO2
So you will get the following program:
Step- Code Program Description

NO-Concentration from channel 1 (ppm)

In the menu "Differential Measurement" you can measure the difference between the
current concentration and a reference concentration of the same gas component. That
means, the measurement value is not based on the zero value as it is usual for an
absolute value measurement. Instead of this the signal will be compared with defined
concentration of the component selected. That may be useful for concentrations that only
differ a little from the basic value of this component in the measurement environment
(Example: CO2 of plant in air).
If you want to make a differential measurement for other components, you can change to
the other channels of an MLT analyzer or analyzer module with the F3 key.
Condition:
¨ You have to calibrate with zero gas and to linearize the measurement channel and the
reference channel.
· To calibrate see 4.5 p. 4-39 and 4.6 p. 4-43 or 5.1.1 p. 5-15 to 5-17.
· To linearize see 5.1.5 p. 5-33
Differential measurement:
1) Dis able the function:
· Press the 8 -key or the ® -key in the line "Function is" to select the parameter and
adjust "Disabled" with the • -key or the ¯ -key. Confirm it with the 8 -key.
· This is necessary to avoid interference of values while the parameters where determined.
2) Select the reference channel:
· Change to the menu line "Choose source channel..." with the ¯ -key and press the
8 -key or the ® -key to go to the submenu "Channels":

can see the channel selected in the line "Source channel".
3) Status determination of the reference channel:
· Change to the line "Source concentration" with the • -key or the ¯ -key and press the
8 -key or the ® -key to select the parameter. Adjust the parameter with the • -key or
the ¯ -key and confirm it with the 8 -key.
· Use actual value:
The reference value to calculate the difference concentration will always be the
current value of the reference channel.
· Us e s tored value:
The reference value to calculate the difference concentration will be fixed during the
whole differential measurement.
4) Give up reference gas to the reference channel:
· You have to give up a defined concentration of the measurement gas to the reference
channel to determine the reference value.
· If the reference signal is stable, you have to change to the line "Store source con-
centration !" with the • -key or the ¯ -key. Press the 8 -key or the ® -key to start this
function. If asked, confirm with the F2 key (Yes) or cancel and go back to the menu
page with the F4 key (Back...) or the ¬ -key:
The current signal will be fixed for the differential measurement.
5) Give up measurement gas to the measurement channel:
· You have to give up the measurement gas to the measurement channel while the
reference signal is stable to measure the differential concentration.
6) Enable the differential meas urement:
· Press the 8 -key or the ® -key in the line "Function is" and adjust "Enabled" with the
• -key or the ¯ -key. Confirm it with the 8 -key:
The differential measurement will start and the differential concentration will be
determined.

„0% value shall be 400 ppm, 100% value shall be 700 ppm
„Analog output is normally:
„After changing the output signal: 0V = 400 ppm
0V = 0 ppm
10V = 1000 ppm
10V = 700 ppm
· Change to the line "Signal value for 0% output" or "Signal value for 100% output" with
the ¯ -key.
· Select the value with the 8 -key or the ® -key.
· Select any digit with the ¬ -key or the ® -key and adjust a new value with the • -key

signal to each output (e.g zero valve) by a corresponding code.
See the tables on the following pages:
+ Signal codes 1 -359: s ee p. 5-75 to 5-77; Function codes : 1 - 599 s ee p. 5-78 !
Set up parameters:
¨ Select the line of variables or the function line with the ¯ -key or the • -key.
¨ Select the variable or start the function with the 8 -key or the ® -key.
¨ If asked after function start: Confirm with the F2 key (Yes) or
cancel and go back to the menu page with the F4 key (Back...) or the ¬ -key.
¨ Variable changing:
Select any digit with the ¬ -key or the ® -key and adjust a new value with
the • -key or the ¯ -key.

4) Determination of the output s ignal values :
· You can determine the signal value for the 0% output and the 100% output in the lines
"Signal value for 0% output" or "Signal value for 100% output". So you have the
possibility to zoom out a certain part of the whole range.
· Example:
„Range from 0 to 1000 ppm
„0% value shall be 400 ppm, 100% value shall be 700 ppm
„Analog output is normally:
„After changing the output signal: 0V = 400 ppm
0V = 0 ppm
10V = 1000 ppm
10V = 700 ppm
· Change to the line "Signal value for 0% output" or "Signal value for 100% output" with
the ¯ -key.
· Select the value with the 8 -key or the ® -key.
· Select any digit with the ¬ -key or the ® -key and adjust a new value with the • -key
or the ¯ -key.
· Confirm the new value with the 8 -key.
· Note:
If you change the measurement range, the adjustment done in this menu will
disappear and go back to the standard values of the range! To change the output
signal values permanently you have to change the adjustments in the menu "Begin
and End of Ranges" (see 5.1.3 p. 5-27)!
· Attention:
The signal range at the analog output should not be less than the littlest range!
Otherwise, the noise level may be very high at the analog output!
5) Determination of the output current range:
· Press the 8 -key or the ® -key in the line "Output current range" to select the range
and select the value you want with the • -key or the ¯ -key.
· Confirm the new adjustment with the 8 -key.
· Options: 0...20 mA (and automatically 0...10V) or 4...20 mA (2...10V).
6) Analog output during calibration:
· In the line "Hold output during calibration?" you can determine the signal drift of the
analog output and of the limits during calibration:
„Yes: During the whole calibration the analog output signal and the status of the
limits are fixed to the last value before calibration.
„No: The analog output signal and the status of the limits are following to the
measurement signal during the whole calibration procedure.
· Notes :
„The adjustments "Yes/No" are valid for all kinds of calibrations of a platform SIO or
MLT analyzer SIO: manual, time controlled, AK controlled and system calibration.
„The signal drift and status of limits of a local SIO in an MLT analyzer module will be
determined in the menu "Calibration Procedure Setup" in the line "Analog output
during calibration: ... Holding/Tracking" (see 5.1.1 p. 5-9/10).

NGA-2000 System Calibration
1 Introduction
In opposite to the possibility to zero and span each analyzer module (MLT channel)
individually and independently from the others, System-Calibration (SYSCAL) allows to
combine the calibration procedures of all into a common process.
This is been achieved with a special assignment of the valves. The idea is not longer to
require for each gas of each analyzer an own valve.
Instead of we have a pool of valves. The valves of this pool can be assigned to the different
gases of the analyzers. That also means different analyzers can share the same valve for
their gases, e. g. for span gas mixtures or a common zero gas valve for several channels. So
we have the possibility to reduce the number of valves and also the consumption of
calibration gases.
The program, which will allow this, runs on the CM (Control Module) and needs
programmable I/O’s (Input/ Output Modules SIO or DIO).
SIO: Standard I/O Module
DIO: Digital I/O Module
SIO and DIO can be located in a platform, an MLT or a TFID analyzer.
The displayed menus are also inscripted with the appropriate LON-Variables.

2 Valves for system calibration
Before using the system calibration we have to put together the required valve pool. There
are in principle three types of I/O modules supporting this:
· DIO
- 24 digital outputs / 8 digital inputs (max. 4 DIO modules per platform or 2 per
MLT/TFID analyzer)
· SIO
· [CVU -
- 3 digital outputs (max. 1 SIO module per CM)
- 4 digital outputs (max. 4 modules per CM)]
Software supports up to 32 system valves. SIO and DIO are available, the control valve unit
(CVU) is in progress.
2.1 Assigning an output port to a system valve
Assigning of an output can be accomplished by using the menus for selected output module
(DIO, SIO or CVU).
There we have to select the NGA Control Module as the Source Module. Control module
then provides the signals for system valve V1...V32.
For example the DIO:

90003482(2) [NGA-e (MLT-Software 3.2.X)] 07/98
NGA-2000 System Calibration
It is also possible to configure the DIO-outputs via LON-Variables (i.e. SLTA-adapter or AK-
protocol).
Therefore is the LON-variable "DIOOUT_ENTRYSIG" which corresponds to DIOOUTSIGC
and evaluates enum-values of ST1NAME (enum-values 0..19), ST2NAME (enum-values
20..39) or ST3NAME (enum-values 40..59).
For digital output we have to setup variables in following order.
1. DIOSLOTIDC
2. DIOOUTNUMC
3. DIOOUTSRCC
4. DIOOUT_ENTRYSIG SYS: VALVE-1
= 20 (enum-value in ST2NAME)
= 21
SYS: VALVE-2
.
.
.
.
.
.
SYS:VALVE-32
= 51 (enum-value in ST3NAME)
For each needed system valve we have to repeat these appropriate selections.
It is also possible to distribute the system valves onto different output modules.

3.1 Set-up analyzer modules
Before we can run any system calibration features we have to include the different analyzer
modules (AM’s) into system calibration by setup needed parameters. Only after correct
setting up, an AM is included into system calibration and only then it makes sense to go into
the other menus.

Setting up an AM for system calibration means assigning valves from system valve pool.
The Control Module provides support of up to 32 system-valves V1....V32. We have to
decide which valves deliver which gases for an analyzer module. Also we have to know the
purge time from a valve to the AM/ MLT channel.
For each of the following types in the parameter „Gas type“ we have to assign a valve and
the appropriate purge time :
·
·
·
·
·
·
SAMPLE-GAS
ZERO-GAS
SPANGAS-1(span gas for range 1)
SPANGAS-2(span gas for range 2)
SPANGAS-3(span gas for range 3)
SPANGAS-4(span gas for range 4)
Conditions for the valve assignment:
·
Once a valve has been assigned to be a sample gas valve for any AM it must not
be used for zero or span gases !
·
·
·
The zero valve of an AM can not be a span valve of the same AM.
All gas types have to be assigned to a system-valve.
TFID has internal valves to be assigned separately as system valves!

Attention: Take in mind that any MLT channel is regarded as AM in this case!
Take care that for TFID separate valves are chosen which are not related
to other AM’s or MLT channels (internal TFID valves only)!
This assigning procedure is to perform for all analyzer modules which should be included in
system calibration.
To display the assigned valves and purge times for each AM we can push the softkey „View“.
If we want to exclude an AM from SYSCAL we can do this by entering an invalid valve.
We can watch in the display whether an AM/channel is enabled for system calibration.
Attention: Remember to assign a system valve to an output-port!

With this parameter we can run all the calibration procedures either in the defined mode
or in a test mode (set test mode to „Yes“). The test mode means that the valve switching
and waiting for purge times is done in the same manner like in the normal calibration
procedure.
The only difference is that the single calibrations of the modules and the appropriate times
the modules would need for the calibration are not done.

3.4 Controlling System Calibration
After setting-up there is the possibility to start 3 different modes:
system zero-calibration:
In this mode a zero-cal of all modules, which are enabled
for SYSCAL, will be performed. The order of modules
depends on purge time for zero-valves because the whole
calibration is time optimized.
system zero/span-calibration:
In this mode will be performed a zero-cal and a span-cal
for every enabled AM. The order of calibration is
optimized to have a minimum of calibration time. The only
condition is to have for each AM first the zero-cal and after
this the span-cal. With zero-cal an AM is zeroed with all
ranges together, the span-cal is done separately for all
available ranges. A range is available if its span-gas value
is > 0.0.
user defined sequence program: In this mode the user is responsible for the optimization.
See setup of this mode.
gas test:
It is also possible to switch for test purposes onto a
special gas of a specific module. A calibration is not
done.
Any mode can be started by the following instances:
· Manually by operator interaction
· Triggered by programmable input (DIO)
· AK-protocol command
· Programmed time-automatic (no gas test possible!)
· LON-Variable CMFUNC
It is also possible to cancel a running system calibration. This can be done by the following
instances:
· Manually by operator interaction
· Triggered by programmable input (DIO)
· AK-protocol command
· LON-Variable CMFUNC
There is no priority by which way SYSCAL can be started. If SYSCAL was started it cannot
be restarted by a further instance. Only after canceling it can be restarted.

For the 3 different SYSCAL-modes there is the possibility to
· enable/disable the activation
· determine start of time calculations (start time of current day)
· determine in which time intervals after start time the activation is done
Attention:
Other than in some AM-functionalities the interval time is to be input as interval hours. For
example, for a weekly calibration you have to calculate 24 h * 7 = 168 h.
The logic for the time calculations is as follows.
The basic is the respectively parameter „Start of interval time“ (SIV-time). By changing this
SIV-time or changing the „interval time“ (IV-time) the basic is new calculated as date of
current day and time of the SIV-Time (only entire hours possible). This basic stays valid (also
after a program reset!) until new values for SIV-time or IV-time are entered.
Basic-time = SIV-Time of current day
The next start of SYSCAL (ACT-time) happens at
ACT-time = Basic-time + n x IV-time
(n = 0,1,2,3,...)
Is the basic time-time before present point of date/time then there are added further IV-times
until it is later.

3.5 Calibrate single Analyzers/ Analyzer Modules/ MLT Channels
Each specific analyzer has still the possibility to start a calibration over other instances than
SYSCAL. For this functionality we now have some additional considerations.
· Do not start a calibration of a single AM or MLT channel during a running SYSCAL.
This will confuse the valve switching and the calibration commands of SYSCAL. Therefore
look also for all automatic start instances of an analyzer.
· A single calibration cannot use the purge times of system valve settings. Instead of we
have to setup the AMs own parameters in the manner to wait for the required purge time
after a valve switching.
· It is refused to start single calibration of a second AM if the needed calibration gas valve is
also any calibration gas valve of the first started AM.
These considerations are valid for all AMs which are included into SYSCAL.

Calibration gas mixtures
Connections for program logic and flow configurations:
· To each AM (channel) must be assigned a sample gas valve.
· During a calibration of an AM the assigned sample gas valve will be closed and returns to
the OPEN-state after the calibration of the AM is done.
· The calibration gases can only flow into an AM if sample gas valve is closed.
· With a opened sample gas valve it is expected to actually flow sample gas.
The state of assigned sample gas valve also decides about some AM specific states!

4.2 Running system calibration
The system calibration is running in an own Task. This task is only allowed to run once. Any
try to restart this task is refused.
The main steps SYSCAL-Task has to do are realized in the following way.
1. Fill all actions to do into a sequence buffer.
2. Make some preparations before starting the actions
3. Work through the sequence buffer
4. Restore states and make some other finishing work
The contents of the sequence buffer depends on the type of SYSCAL (ZERO_ALL,
ZEROSPAN_ALL or USER_PROG). With the start command this type is delivered.
It is allowed to cancel the SYSCAL-task. This is realized by setting a parameter to a defined
value. This parameter is watched during step 3("working through the sequence buffer").
If a cancel is caused the task cancels its current action in step 3, works through step 4 and
ends.
Cancelling the SYSCAL-task per digital input will also disable any further starting action as
long as the digital input will stay at „cancel-state“.

One calibration type has following sequence frame:
1. SWITCH_VALVE
2. do different PURGEWAIT, ZERO, or SPAN which are possible with this valve adjustment
(order is determined by shortest purge time)
3. do different CALWAIT (wait for finishing a started calibration)
The evaluation procedure optimizes the order of actions by time.
The only condition is in case of ZERO/SPAN-CAL, where an AM has to do first its "ZERO"
before any of its "SPAN"s can be done.
The PURGEWAIT-delay-measurement is started with the last SWITCH_VALVE-action.
We can see, that the SYSCAL-types "ZERO_ALL" and "ZEROSPAN_ALL" are special cases
of a user program.

4.2.2 Before starting actions
Before any action of sequence buffer is done there are some preparations to do:
· store previous calibration time for the case of cancelling
· previous calibration time is now the actual one
· actual calibration time is reset
· cancel any running calibration of an AM
4.2.3 Control of actions
4.2.3.1 Switch valves
The SWITCH_VALVE action just takes the action data[0] (valve mask) for the new setting of
system valves.
We have just to modify LON-variable STCONT3, STCONT4 and partially STCONT5 , which
are linked to system valves.
This action also resets time (takes system tick) for delay measurement of purge times.
4.2.3.2 Wait for Purging
The PURGEWAIT-action looks for the present time went over since last SWITCH_VALVE-
action.
For the still required difference up to the needed purge time is now waited. It gives time to
other tasks. If there is no additional time to wait it is continued directly with next action.

4.2.3.3 Zero Calibration
Before starting of zero calibration there are some parameters (LON-variables) to modify.
After ending system calibration these modified variables are restored to their previous value.
· CONTROL:
This variable determines which instance is controlling range of an
AM. The parameter is set to "controlled by control module"
This variable determines if all ranges are zeroed together or
separately. The parameter is set to "zero all ranges together".
This variable exists only in a multi-channel AM (MLT!) and
determines if the AM has a serial/parallel gas flow.
· ZERORNGS:
· AMSERPHYSTAT:
The parameter is set to "parallel gas flow" because only this state
allows SYSCAL to calibrate the different channels simultaneously.
After modifying these parameters zero calibration is started by LON-variable:
· AMFN:
This variable can start functions on a AM. It is set to the value for
function "Zero".
4.2.3.4 Span Calibration
The span calibration can be done only in single ranges. Any action for a span calibration in a
range can only be done if "spangas value <> 0.0".
Before starting then span calibration there are some parameters (LON-variables) to modify.
After ending system calibration these modified variables are restored to their previous value.
· CONTROL:
This variable determines which instance is controlling range of an
AM. The parameter is set to "controlled by control module"
This variable determines if all ranges are spanned together or
separately. The parameter is set to "span all ranges separately".
This variable exists only in a multi-channel AM (MLT!) and
determines if the AM has a serial/parallel gas flow.
· CALRANGES:
· AMSERPHYSTAT:
The parameter is set to "parallel gas flow" because only this state
allows SYSCAL to calibrate the different channels simultaneously.
This variable controls the current range of an AM. It is set to the
respectively required range.
· CRANGE:
After modifying these parameters span calibration is started by LON-variable:
· AMFN:
This variable can start functions on a AM. It is set to the value for
function "Span".

4.2.3.5 Wait for Finishing Calibration
Any AM has the LON-variables
· CALSTAT
Whether the selected AM is still calibrating or not, is checked by reading the variable
CALSTAT.
This CALSTAT-check is done in time intervals. During the intervals time is given to other
tasks.
4.2.4 Finishing System Calibration
After system calibration was working through the sequence buffer or it was canceled there is
to do some finishing work.
· Actualize some displayed LON-variables
· Look for some still running calibrations in case of cancelling and cancel them, too.
· Restore modified LON-variables of AMs.
· Switch system valves to sample gas state for all AMs
· Cause to set any AM’s LON-variable PROCESS = "valid sample gas" after purging time of
sample gas valve.

4.3 Running Single Analyzer Calibration
A single analyzer calibration also needs to switch appropriate system valves.
The difference to the system calibration is that calibration procedure of AM is already running
and we have to respond upon this state.
The reaction is possible by watching any change of the LON-variable CALSTAT.
· CALSTAT_ZERO (zero calibration in progress): switch off belonging sample valve and
switch on zero valve.
· CALSTAT_SPAN (span calibration in progress): switch off belonging sample valve and
switch on span valve appropriate to
current state of CRANGE-variable.
· CALSTAT_DONE (calibration finished):
switch on sample valve and switch off
calibration gas valves.
After a calibration command the AM itself is responsible to wait the required purge times until
calibration actually is done.
The reaction onto a CALSTAT-change is only active if no system calibration is running.

4.4 Holding analog outputs of the SIO and avoid limit violation alarms
Any AM has LON-variable:
· PROCESS
This variable is an input-variable. Its meaning is to tell the AM that another instance is not
allowing the measurement sample to flow valid.
In the AM are some states depending from PROCESS.
· "valid measurement" only if PROCESS = "valid sample gas".
· holding analog outputs if PROCESS = "no valid sample gas"
· watching limit violations is switched off if PROCESS = "no valid sample gas"
It's now the task of the system calibration to handle the variable PROCESS for any involved
AM. This is done in the following way:
Any switching of a system valve looks if in the switched valves is a sample valve of any AM.
If yes, then it sets PROCESS like follows.
sample gas
valve
time delay
PROCESS-
variable
switched off
switched on
-
sample not valid
sample valid
purge time of sample valve
It's very important to notice following:
SYSCAL only watches state of appropriate sample gas valve for setting of PROCESS-
variable.
Any additional valve, serial to sample valve, which can switch off flow of sample gas can not
be registrated for logic of PROCESS-variable.
