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 CM
♦ Analyzer Module AM
♦ Input/Output Modules 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:

System Unit SIO/DIO-Configuration

• 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

installed in the MLT analyzer
module

⇒ SIO and DIO can be configured

Platform (CM Software):

• Control unit with front panel

• Without measurement channels

⇒ 1 SIO and up to 4 DIO's can be

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:

(C) 1998 FISHER-ROSEMOUNT Analytical

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 com­ponent 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 battery­powered 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 mea­surement 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 correspond­ing 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 CO

• 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".

♦ Disabled: The calibration procedure is running without stability and tolerance control.

Any Calibration will be accepted.

Example:

♦ End of range: 1000 ppm
♦ Max. calibration deviation: 20% (equivalent 200 ppm)
♦ Desired value: 990 ppm
♦ Display: 720 ppm
♦ Deviation: 250 ppm (more than 200 ppm!)
♦ Result: Max. calibration procedure time over limit;

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.

Notes:

♦ The time controlled calibration is only possible if the span gas comes from a valve gear!

If the valve gear is not available you have to select "Never" in all lines containing "Day
of week".

♦ A zero gas calibration should be done before starting a span gas calibration. Therefore

the starting time of the zero gas calibration should be different from the starting time of
the span gas calibration. If you select the option "Zero+Span calibration" the zeroing will
run before the spanning, automatically.
