GLOSSARY OF TERMS
30 A Bulk Power Supply
A power supply that is mounted in an enclosure capable of supplying power (+24 VDC @ 30 Amperes) to
up to ten Analyzer modules installed in the NGA 2000 System.
AK
A serial interface protocol, popular in Europe in the automotive industry.
AMSN
Network variable name containing the module Serial number. This should be the same as the number
physically marked on the unit.
Alarm
An indication (normally) of an out-of-normal circumstance. This covers status indications, concentration
limit violation, internal limit violations or an internal problem. Alarms may be indicated to the user either
visually or through a relay contact closure.
Analyzer module
Self contained analysis modules that are designed to be installed into the NGA 2000 System. One Analyzer
module can be installed into a Single Enclosure containing the Platform Module. Two Analyzer modules
can be installed into a Dual Enclosure. The simplest NGA 2000 System consists of one Analyzer module.
Backplane
The Controller Board, Power Supply Board, I/O Board(s) and Expansion Board(s) are plugged into the
Backplane
Basic Controls
In the NGA 2000 menu system, refers to the controls appropriate for normal operator use. These include
such things as range changing, zeroing the Analyzer, and lighting the flame on a FID Analyzer.
Bench
The physical measuring device within the Analyzer module. It comes from the term Optical Bench, describing the specialized optical components used in the original Analyzers.
Binding
A process by which Analyzer modules and I/O modules are instructed with whom to communicate over the
LON. Once bound, variable updates from one module are automatically transferred to the other.
Calibrate
In Internal Combustion Exhaust Emissions monitoring, to zero, span and linearize an Analyzer. In other industries, to zero and span an Analyzer.
Calibration cycle
A procedure for making an Analyzer read sample gases correctly. It involves flowing zero gas, waiting for
stabilization, causing the Analyzer to adjust its zero offset, and then doing the same for one or more span
gases with adjustment of span factors as required.
CLD
Chemiluminescence Detector - a term for the type of Analyzer that measures nitrogen oxides by measuring
the light emitted when nitric oxide reacts with ozone.

Polynomial
A mathematical term meaning an expression (a function of a variable) containing several terms, each of
which contains a power of the variable. A + B X x + C X (x X x) is a second order polynomial in x. A,B and
C are its zeroth, first and second coefficients. "X" means multiply, as usual.
Power Supply Board
The Power Supply Board that plugs into the front of the Backplane capable of supplying power (+24 VDC
@ 5 Amperes) to the platform components and just one Analyzer module mounted within the platform.
Primary Variable
The measured species concentration value from an Analyzer module.
Range
The bounds of concentration over which the Analyzer's reading is accurate, or possible. Traditionally this
is set by the Analyzer circuitry or its physics: in NGA 2000, it is often merely a mathematical fiction provided for operational convenience.
Response Factor
The relative response of the Analyzer to different gases to which it is sensitive. In the case of the FID this
refers to its response to various hydrocarbons, which is roughly in proportion to the number of carbon atoms contained in the gas' molecule.
Safety Failure
Indicates a failure of the Analyzer safety system, with resultant shut down of the Analyzer.
Secondary Variable
The current status data placed on the network by an Analyzer module. The includes sample flow, source
voltage and other diagnostic information.
Serial Number
A number assigned to the module at time of manufacture. It is stored in the network variable AMSN, and
marked on a label on the module enclosure.
Softkeys
The five function keys located below the front panel display. The menu function for each softkey is displayed directly above it and is controlled by the software.
Solenoid Valves
A gas switching element controlled by electrical current. It is used to control the flow of sample or calibration gas to an Analyzer.
Span
The range over which something works, or the act of standardizing the upper end of the range.
System
A NGA 2000 System consisting of one (or more) Analyzer modules, an optional Platform, one or more optional I/O Boards, an optional Expansion Board and an optional 30 A Bulk Power Supply.
System Integrator
An individual or organization who designs and builds analytical systems. Typically these are panels containing one or more Analyzers together with the sample system components and any other devices required for stand-alone operation.

In the NGA 2000 menu system, refers to the controls and configuration capability, and diagnostic information appropriate for Analyzer technicians.
THC
Total Hydrocarbons, a term for the total quantity of hydrocarbons present, regardless of their type.
Tweak
A slang term meaning to adjust. Used in the NGA 2000 system specifically to describe a process of modifying the linearity of an NGA 2000 Analyzer.
Validity
A concept used to describe a condition in which gas concentration values present on the Operator Interface
or output lines should be considered valid or invalid. The Analyzer module alerts the system that an error in
gas concentration is present. Causes include failure or lack of calibration, flame out in a FID, or a not-fromprocess gas applied by a sample control module.
VBA
Visual Basic for Applications - Microsoft's version of Visual Basic that they supply built into their main applications such as Excel or Word. It is similar but not identical to the stand-alone Visual Basic, and each variety has its own idiosyncrasies.
Warning
A form of alarm: a warning indicates one or more software configured limits on any network variable (other
than gas concentration) has been exceeded. Examples of these secondary variables are flow rate and internal voltage. A warning indicates that the Analyzer reading may not be correct.
Zero
To make the Analyzer read zero on zero gas, by calibrating its offset. Also the operation that accomplishes
this.

and any I/O to the system goes through it. (It is
also possible for a computer to talk directly to
the Analyzer modules without the need of a
Platform, but that is outside the scope of this
document.)
THE NGA 2000 CONCEPT - INTRODUCTION
NGA 2000 stands for "Next Generation Analyzer". It describes a new concept in gas Analyzer design. The basis for this concept is the
division of the traditional Analyzer functions into
modular parts, connected by a digital communication link called LON.
Traditional Analyzers contain the "physics" - the
mechanism for detecting the gas in question and a means of controlling the operation of and
getting data from the physics. This normally
consists of a display with associated controls on
the front of the box, and "I/O" (input/output)
consisting of an analog or sometimes RS232
output, together with some relay contacts, on
the back. Power is supplied by an AC connection to the wall plug. Each Analyzer in a system
has to contain all of these components.
In the NGA 2000 concept, the physics is separated from everything else into an "Analyzer
module", and a single "Control module" or
"Platform" (so called) contains the control, display, I/O and power supply components.
Communication between the Analyzer module
and the Control module is by means of a sophisticated digital communication system made
by the Echelon Corporation, called LONWORKS™ or LON™. There are many subtleties involved in such systems, but the NGA
2000 and the LON hide almost all of these from
the user. A great deal of the sophistication of
the NGA 2000 concept is involved in making the
communication system extremely simple to use
and in removing the complexity that, for example, your MIS administrator has to deal with
while managing the LAN (Local Area Network)
you probably have to use at work!
A typical NGA 2000 system then consists of a
number of different types of Analyzer modules
connected to a single Platform, with some selection of I/O provided according to the particular needs of the user. Control of the entire
system takes place through the single Platform,

THE DIGITAL COMMUNICATIONS SYSTEM –
INTRODUCTION
The NGA 2000 uses a proprietary digital communication system made by Echelon Corporation, called LONWORKS™ or LON™ for short.
It is a sophisticated system that deals with most
of the subtleties required without user intervention or knowledge, but there are certain aspects
of it of which you should be aware.
The LON sends data in packets called "Variables". These are named, so that, for example,
the main output of an Analyzer is contained in a
variable called "PVA". Its range is contained in
a variable called "CRANGE". These variables
are emitted by the source and read by other
modules on the network that are interested in
them.
I/O Modules contain input variables of the same
name, and when the I/O is "bound" to an Analyzer module, the contents of the Analyzer's
PVA are automatically communicated to the
I/O's PVA, so that it now knows what the Analyzer's reading is. It can convert it to a 4-20mA
signal, or whatever it is configured to do. Obviously it is important that the I/O Module knows
which Analyzer to listen to!
The way we tell the I/O Module which Analyzer
it should pay attention to is to "bind" it to that
Analyzer. This process selects an Analyzer,
selects an I/O Module, and ties them together
so that the set of Analyzer variables is bound to
the equivalent set of I/O variables, and the two
act as if they are one unit. The process itself is
described below, and it is much easier in V2.3
than in V2.2 and earlier versions. It is the only
thing you have to do to configure the LON.
Description and Specifications

Instruction Manual
760006-A

The other thing to realize is that the LON is extremely reliable. Any apparent problem with it
has always been proved to be from some obvious error, like a broken wire. It is possible to
overload it, and there is information in this and
the reference manual about this, but once a
system has been setup the LON itself keeps
working. If there is a problem, look for other
things besides the LON to be at fault!

PLATFORM OVERVIEW
This manual describes the Control and I/O capabilities of the Platform part of an NGA 2000
system.
NGA 2000 system consists of three basic elements:
• Platform components
• Analyzer modules
• Input/Output (I/O) Modules
The Platform serves as a local operator interface for up to six (ten for V2.3 and higher) Analyzer modules. It consists of a group of
components that can be assembled in many
different configurations depending on the user's
needs. It can be composed of any workable
collection of the following:
• Operator Interface - Front Panel,
Display and Keypad
• Power Input Module/ Power Supply
Board
• Platform Controller Computer
• One or more of a number of I/O
Modules
• Enclosure.
The Platform is also available in a dual version,
with two complete independent sets of electronics in one enclosure. Such dual versions
act as two separate Platforms and allow two independent Analyzer systems to be run from one
place. The front panel in this case consists of
two half panels directly mounted on the chassis
with no hinges.

Description and Specifications
Model NGA 2000 Platform
The NGA 2000 family of gas Analyzer modules
utilizes proven methodologies such as:
• Non-dispersive infrared (NDIR) to
measure gases such as carbon
monoxide (CO), carbon dioxide
(CO2) and sulfur dioxide (SO2)
• Paramagnetic (PMD) for measurement of oxygen
• Chemiluminescence (CLD) for
measurement of nitrogen oxides
(NO and NOX)
• Flame ionization detection (FID) for
measurement of total hydrocarbons (THC).
• Further modules made in Europe
and described in their own manuals. These include the MLT (a
multi-analysis module) and the
NGA 2000 II series.
These gas detectors are packaged in standard
sized modules that can be linked together via
the LON communications network. The modularity of NGA 2000 allows for the use of multiple
interchangeable Analyzer modules with no
change in overall operational characteristics.
The I/O Modules provide signal input and output
capability outside of the NGA 2000 communications network and are designed for easy installation in the Platform. I/O Module options
provide analog and digital signals, dry contact
closures for alarms and calibration valve sequencing, and accept remote signals for range
change and calibration initiation. These I/O
Modules contain a small computer that operates
autonomously providing I/O capability through
the LON connection without burdening the
Analyzer module computers.
The SIO Board and DIO Board are extensions
to the Platform Controller Board. They plug into
the back of the Platform just as do the I/O Module boards, but they do not contain on board
intelligence. The Platform will only accept one
SIO board but it is possible to add up to four
DIO boards - but only if the software in the
Platform is V3.3, or higher. (At the time of writing, this software is not available in the USA.)

Instruction Manual
Model NGA 2000 Platform
The LON I/O Module boards allow for external
LON connections to the Platform.
Components that comprise the Platform and the
I/O Modules can be assembled in other configurations depending on user needs.
NOTE
The Platform controller board software
must be of a later major revision than
any Analyzer module software. For
example, a V2.2 Platform controller
board will work with V2.2.1 Analyzer
modules, but not with V2.3 Analyzer
modules. The ".1" after the V2.2 refers
to a minor revision, which is compatible with the V2.2 Platform controller
board software.
NOTE
It is strongly recommended that you
note the actual software revisions that
you have. Service or support people
will be able to diagnose any problem
you may have more easily if this information is immediately available.
The revision is marked on each component, as well as noted in their Manufacturing data menus.

THE LON – THE NGA DIGITAL COMMUNICATIONS NETWORK
The NGA 2000 Digital Communications Network
operates over a bi-directional, peer-to-peer, twowire system at a rate of 78 kbps. Modules are
connected with RJ-45 modular connectors and
UL level 4, 100 Ohm LAN cable. This means
that there is a single wire connection between
all the modules on the network. It plugs into
each module using a plug much like standard
telephones use. (In fact the wiring is not critical,
plain wire connections will work well over reasonably short distances such as 100 feet.)
The network utilizes LONWORKS®, an open
control networking technology developed by the
Echelon Corporation. This uses the
LONTALK™ protocol. The combination of the
NGA 2000 modular architecture with the robust
LONTALK™ protocol allows the capability to
“multi-drop” nodes to create a distributed net-

work. This is to say that it is possible to connect
many devices onto the same network, and the
network protocol keeps everything working
without conflicts.
Every Analyzer modules or I/O Module node
that communicates to the network contains a
NEURON CHIP. This chip integrates three microprocessors, ROM, RAM, and EEPROM
memories, timers, multifunctional I/O, and the
network interface. From the user perspective
the inner complexities of the LON are thoroughly hidden from view and can safely be ignored.
The network is self-installing upon startup. The
Platform acts as a Network Manager, assigning
addresses and generating its own database
automatically. Manual intervention is only
needed to determine linkages (“binding”) between Analyzer modules and I/O Modules. This
means that all you have to do is to connect everything and power it up, and then tell it which I/O
Module is connected to which Analyzer. Once
this has been done once, it never needs to be
done again unless modules are exchanged or
added.
Each NGA 2000 Analyzer module transmits
over two hundred pieces of data (called variables) that are characteristic of its specific gas
detection methodology. In addition to the main
reading - the primary or process variable (gas
concentration), many other parameters and
pieces of diagnostic information are available.
This data includes:
• Manufacturing data such as serial
number and software revision
• Configuration setup for calibration
control, component temperature
and other alarm set points, and
linearization parameters
• Operational status conditions such
as faults and calibration
• Secondary variables such as type
of gas measured, flow, temperature, and pressure readings
• Historical data such as known
good calibration values and factory
configuration settings

PC INTERFACE
There are several ways of using the NGA 2000
system with a PC. The Platform can support
RS232 or RS485 interfaces, using either AK or
Modbus as the protocol. Modbus is described
in detail in this manual, and AK is touched on
here and more extensively in the NGA 2000
Reference manual.
It is also possible to setup a PC to communicate
directly with the LON. The easiest way is to use
the Rosemount Analytical DDE Server, together
with a set of suitable hardware. This is described briefly in the NGA 2000 Reference
manual, and in detail in the DDE Server manual.

V2.3 and higher Controller boards come
with additional memory and can support up
to 10 Analyzer modules with their associated I/O Modules. This board can be reprogrammed locally through a PC serial port
if desired to upgrade its software.
If the Platform Controller Board malfunctions, the Operator Interface will be affected, but the Analyzer module will
continue to produce an accurate Primary

c. Power Input Module/Power Supply
Power can be supplied to all NGA 2000
components through the Power Input Module, which plugs into the Backplane. External line voltage (85 to 264 VAC, 50 to 60
Hz) is supplied to the Power Input Module
and conditioned for usage by other NGA
2000 components. See Figure 1-3 and Figure 1-10.
The Power Supply Board also plugs into the
Backplane and conditions incoming power
for usage by all modules (only one Analyzer

module). The Power Supply Board provides
+24 VDC at 5A.
Alternatively, the user may supply regulated
24 VDC directly to the Platform through the
Power Input Module. If multiple Analyzer
modules are used, a larger 30 A Bulk Power
Supply is required to power the system.
If the user initially applies AC power and
then applies DC power, the DC circuitry assumes control, and all components may
continue operating without interruption but
may reset depending on the current draw. If
the user initially applies DC power, application of AC power will have no effect. DC
power will remain in control. If both AC and
DC power have been applied, removal of
DC power will reset the system, and AC circuitry will then assume control.

MULTIPLE MODULE COMPONENTS AND
SYSTEM INTEGRATION
The Rosemount Analytical NGA 2000 architecture provides significant system integration capabilities.
The compact 5.25" height and component
modularity allow for space efficient mounting,
thus decreasing the required panel or rack
space required by conventional Analyzers. The
Analyzer modules may be mounted virtually
anywhere inside a panel; they can be rack
mounted, floor mounted, installed inside the
Platform, or even externally located.
Since a single Platform can accommodate up to
ten Analyzer modules and up to five I/O Modules, the total number of "Nodes" allowed in any
one Platform group is fifteen. This combination
of Nodes may consist of any number of Ana-
1-10
Description and Specifications
Model NGA 2000 Platform
lyzer modules and I/O Modules which total fifteen or less. Should additional I/O Modules be
required, these may be housed in an ancillary
Analyzer enclosure. Additionally, some Analyzer modules, such as the MCFID (Multi Component Flame Ionization Detector), or MLT
(Multi Method Multi Component) Analyzer modules, actually provide discrete analysis of more
than a single component and thus are considered, by the Platform, to be more than a single
Analyzer. Once a "Node Group" has been configured it may be networked with additional
Node Groups by means of a Router Assembly
(see Figure 1-9) which provides a discrete address for that Node Group and isolates it from
other Node Groups.
Individual Analyzer modules require 24 VDC
power. As shown in Figure 1-8, this power may
be provided by individual power supplies located in the Platform or by the 30 A Bulk Power
Supply which can provide up to 30 amps of 24
VDC power. The 30 A Bulk Power Supply can
provide power for up to 10 NGA 2000 components.
Table 1-1 may be used to calculate the total
number of Analyzer modules and I/O Modules
which may be supported by a single Platform
(Node count ≤ 15), and the total power requirements for any single Node Group (30 A Bulk
Power Supply ≤ 30 Amps).

The Dual Analyzer Enclosure simply provides
space for two Analyzer modules as well as rear
panel power and network connections for both.

inside the Platform is not sufficient. The supplemental 30 A Bulk Power Supply is capable of
powering up to 10 NGA 2000 components, but
is limited to 30 Amps (refer to Table 1-1)
WARNING.
OVERHEATING HAZARD
If only one Analyzer module is installed, only
one cable need be connected to the network or
Platform supporting the Analyzer module
If a standard Platform is used in conjunction
with multiple module components, power should
be connected to the Platform's 24 VDC connector on the Power Input Module and the network cable should be connected to the Network
Port (see Figure 1-3).
The Single Analyzer Enclosure provides additional flexibility in system design. It is a standard
Platform (with room for one Analyzer module)
with no front panel display. It can be ordered
with or without a 5 A Power Supply Module, depending on whether the user can provide
24 VDC power.
To prevent the 30 A Bulk Power Supply from
overheating ventilation openings on the top,
bottom and rear of the enclosure should not
be blocked.
NOTE
Early multi-module power supplies
were supplied with 5A fuses installed,
these fuses were inadequate for the
HFID (Heated FID) and WNX (Wet NOx)
Analyzer modules. When powering
these modules, 8A fuses are recommended. The internal wiring is adequate for this current, early
supplemental supplies are, however,
limited to 25 A total.
The 30 A Bulk Power Supply provides the additional 24 VDC energy necessary to power an
entire system (standard Platform, I/O Modules,

Panel is shown in Figure 1-10 under the arrow on the right side of the figure.
1-10 I/O MODULE
a. Overview
The I/O Modules are plugged into the Backplane of the Platform. Up to five I/O Modules can be installed into the Backplane of
the Platform as shown in Figure 1-10 and
Figure 1-11.
Figure 1-12 provides the I/O Module component locations and mounting dimensions.
The available input and output functions include voltage outputs (0 to +5 VDC), current
outputs (0 to 20 mA and 4 to 20 mA),
alarms (3), auto calibration, remote range
change and identification and gateway
translations such as the Modbus protocol.
Each I/O Module contains a NEURON
CHIP microprocessor which acts as a Node
on the Local Operating Network (LON). The
NEURON CHIP also controls the functions
of the I/O Module in accordance with the installed software on the I/O Module. These
functions can be modified via the Operator
Interface of the Platform. The SIO and DIO
boards are controlled by menus contained
within the Platform Controller board menus.

b. Analog Functions And I/O Connections
The I/O Modules that include analog function provide seven relay contacts (contacts
are rated 24 VDC at 1 Ampere resistive)
outputs [three single-pole, double-throw
(SPDT) and four single-pole, single-throw
(SPST)], one analog output and six digital
inputs. Figure 1-14 provides the I/O Module
output connector and adapter pin assignments. Table 1-3 provides the I/O Module
Input, Output and Power Specifications. If
the I/O Module is installed in a Platform, the
24 VDC power is derived from the Platform
and no external power is required.
It is equipped with EMC protection devices,
but it is essential that no more than 24V be
applied to any of its pins. This includes the
analog output which is isolated from the
metallic shield, but which also has EMC devices which restrict the maximum common
mode voltage allowed.
I/O Modules can provide standard automatic range change between high and low
ranges. A user-adjustable time delay is
available to prevent range switching caused
by a noisy environment.
Note that the connector on the I/O Module
is a male 25 pin sub D shielded connector.

WARNING.
CAUTION.
Before starting to install this equipment, read the “Safety instructions
for the wiring and installation of this
apparatus” at the front of this Instruction Bulletin. Failure to follow
the safety instructions could result
in serious injury or death.
HAND INJURY HAZARD
UNPACKING
If the Platform is received as a separate unit,
carefully examine the shipping carton and
contents for signs of damage. Immediately
notify the shipping carrier if the carton or
contents is damaged. Retain the carton and
packing material until all components associated with the Platform are operational.
2-2
Do not place hands or fingers in
Platform front handles when the
front panel is open. Dropping front
panel while hand or fingers are inside either handle can cause serious
injury.
LOCATION
Install Platform components in weatherproofed, non-hazardous, vibration-free locations isolated from extreme temperature
variations. For best results, install near the
sample stream to minimize sample transport
time if the Platform contains an Analyzer
module.
WARNING.
POSSIBLE EXPLOSION HAZARD
This equipment may contain modules used in the analysis of sample
gases which may be flammable. If
used for analysis of such gases, the
module must be protected by a continuous dilution purge system in accordance with Standard ANSI/NFPA
496-1993, Chapter 6.
Rosemount Analytical Inc.
A Division of Emerson Process Management
NOTE
If this Platform is stored in an environment whose ambient temperature is below 5°C (41°F), it must be
moved into a room temperature environment for 24 hours before powering up. Otherwise, moisture may
form inside the LCD display.
NOTE
Unrestricted air flow in the rear of
the Platform is critical to the component's performance and reliability. The 30 A Bulk Power Supply
module requires unrestricted air
flow vertically through itself. It
should therefore not be placed between other modules which restrict
this flow
Although the NGA 2000 Flame Ionization
Detectors (FID and HFID) contain Type Z
purge equipment due to the presence of an
internal source of flammable gas, the instruments are designed for non-hazardous locations. Type Z continuous dilution purge is
designed to provide protection in accordance
with standard ANSI/NFPA 496 (1993),
Chapter 6 when sampling non-flammable
gases. Do not place this (or any general purpose) Analyzer in a hazardous environment.

connections must be removed to disconnect
power from this unit.
ELECTRICAL REQUIREMENTS
The NGA 2000 Series Platform and MultiModule Power Supplies can operate on any
AC line voltage between 85 and 134 VAC,
and between 218 and 264 VAC and the
Platform and Analyzer modules can also operate on any regulated 24 ±5% VDC power
source. Power consumption (wattage) is dependent on the number and type of modules
connected together as a system. Wiring used
must meet the current draw requirements of
the Analyzers concerned.
WARNING.
ELECTRICAL SHOCK HAZARD
When using the 30 A Bulk Power
Supply, use a power cord rated at 13
A, 125 V and 1625 W or better. A
cord with a lower rating may overheat and cause a fire hazard.
Earlier versions of the Power Input Module
were factory-equipped with 115 VAC fuses (2
required). In this case, if available line voltage
is 230 VAC, replace the fuses with the accessory fuses found in the shipping kit that accompanied the Platform. Current Platforms
are equipped with a Power Entry Module that
does not require such a fuse change.
2-4
24 Volt power wiring must be connected individually to each Analyzer module in a star
configuration (i.e. an individual set of wires to
each Analyzer), using appropriate gauge wire
to tolerate the current draw. The ground
connection must be made to each Analyzer
module and returned to a high quality common ground point. This connection should
not be used as the power return wire.
2-5
The LON connection wiring may be made in a
daisy chain fashion. If the total length of the
LON connection exceeds a few meters, the
configuration should be restricted to a daisy
chain, with LON termination devices at each
end of the connection. Distances of less than
about ten meters are not as critical, and such
connections may be made in a star formation.
The wiring used must be level 4 LAN twisted
pair wiring, (100 ohm impedance), preferably
shielded. Standard 8 pin RJ45 telephone
plugs and jacks are used, with pins 1 and 2
carrying the signal, all others being unused.
Terminal block connections are permissible
for junction boxes, if desired.
A dual version of the Platform is available by
special order. This contains two complete
sets of Platform electronics including AC input and power supply. Note that both AC

Installation
GAS REQUIREMENTS
Since gas requirements (e.g., flow rate, flow
pressure and connections) vary between the
available Analyzer modules, information concerning this can be found in each Analyzer
module manual.
I/O REQUIREMENTS
Input/Output requirements (including connections) are dependent on Analyzer modules
and applications. Information concerning
these requirements can be found in the I/O
Module section of this manual.
Various adapters are available for use with
the I/O Module DB25 connector. See the
spare parts list Contact the factory for availability.

I/O MODULE
a. Installation
Remove power from all the components
of the NGA 2000 System before installing
an I/O Module.
To install an I/O Module into the Platform,
perform the following steps:
1. Remove a blank panel from one of
the unused I/O Module slots as
Rosemount Analytical Inc.
A Division of Emerson Process Management
Instruction Manual
Model NGA 2000 Platform
shown in Figure 1-11. Retain the
blank panel for future use.
2. Hold the I/O Module by the rear
panel and insert it into the open slot
making sure that the printed circuit
board is aligned with the card
guides at both the top and the bottom.
3. Push the I/O Module completely
into the slot to insure that the module connector mates with the Backplane connector.
4. Tighten the two captive screws on
the I/O Module Rear Panel.
b. Removal
Remove power from all the components
of the NGA 2000 System before removing an I/O Module.
To remove an I/O Module from the Platform, perform the following steps:
1. Loosen the two captive screws on
the I/O Module Rear Panel.
2. Push down on the extractor handle
to extract the I/O Module from the
backplane connector. Carefully pull
the module out of the slot.
3. Install a Blank Panel to cover the
slot.
c. Software Configuration
Configuring the software for an I/O Module is performed using the Platform Display and Keyboard. First, an I/O Module
must be bound to the associated Analyzer module. If only one Analyzer module is used, all installed I/O Modules are
automatically bound to the Analyzer
module. The second step consists of
custom configuration of the I/O Module
and selection of desired options and parameters.
Rosemount Analytical Inc.

d. Binding Procedure v2.2
In an NGA 2000 System that contains
only one Analyzer module, binding between that module and any I/O Module(s)
will occur automatically upon startup.
If the system contains multiple Analyzer
modules it will be necessary to bind each
Analyzer module to the associated I/O
Module(s). To bind a newly installed I/O
Module to an Analyzer module perform
the following steps:
1. From the Main Menu, make the following selections: Technical Level
Configurations, Listing of All Modules. The Listing of All Modules
screen shows all NGA 2000 components (Analyzer modules, I/O
Modules and Platform [Control
Module]) recognized during the initialization of the network. Any module connected (or disconnected)
after initialization will not be recognized until the system is reinitialized. Ensure that the system
recognizes all modules on the network. If it does not, the problem
must be isolated and corrected before continuing further.
2. On the Listing of All Modules
screen, ensure that each module
has a unique user tag number.
Later I/O modules will be able to
add their slot ID to their TAG as
shown on this screen. If so, you do
not need to otherwise identify them.
It is this tag number that is used to
bind an I/O Module to an Analyzer
module. For example, in a system
consisting of two NDIR modules,
two FID modules and one CLD
module, the tags could be chosen
from Table 2-1.
3. The user tag numbers should be
somewhat logical in their description to avoid confusion. They
should not contain a period (.) so as
to avoid confusing PC software that

NOTE
From the Listing of All Modules screen,
the diagnostics of a selected module can
be selected. The I/O Module diagnostics
displays the I/O Module tag number and
allows it to be changed if necessary. To
change the Analyzer module tag number,
however, access the Analyzer Manufacturing Data screen by making the following selections: Technical Level
Configuration, Service Menus, Manufacturing Data, or Expert Menu, Analyzer
module Setup, Analyzer module Tag. The
initial Analyzer module tag number is set
during production test and may be
meaningless from the user's standpoint.
I/O Module tag numbers initially will
probably each read "Analog I/O, Autocal
I/O, SCAL,", etc.
4. Once all Analyzer modules and I/O
Modules have unique tag numbers,
binding can begin. Note that earlier
I/O Modules were not identified as to

5. Note the physical location of each I/O

module systems is the assumption
that a module is not responding (no
output response - voltage, current,
alarms) when actually the wrong I/O
Module was being accessed.

Configuration, System Setup, Module
Binding, Select Modules.
8. Ensure that the Analyzer module selected is, in fact, the one to which an
I/O Module is to be bound. Select the
I/O Module to be bound. The screen
will appear as “Proposed New Bind”.
If the proposal is correct, press the
“BIND” softkey. If incorrect, return to

the “BIND” softkey is pressed, the
system will reinitialize automatically.
9. To achieve binding between other
Analyzer modules and I/O Modules,
return to the top level display screen,
select the next Analyzer module and
repeat steps 5 through 7. As I/O
Modules are bound, they disappear
from the Select I/O Module screen because they are no longer available for
binding. In a system with only one
Analyzer module, no I/O Module
would appear in the Select Module
screen since they are automatically
bound upon initialization of the system.
NOTE
Do not press the “UNBIND” softkey, doing so would unbind all modules, requiring the user to repeat the complete
binding procedure. However, if a binding mistake is made, the only way to correct the mistake is to press “UNBIND”
and repeat the binding procedure. Also,
do not press the “RE-INIT” softkey during any of the automatic re-initializations
in the binding process. If the “RE-INIT”
softkey is pressed, this will abort the
binding process and all prior binds will
be removed.
10. Verify all bindings by selecting View
Bindings in the Module Binding
screen. A “miss-bound” module can
lead to confusion and mis-diagnosis of
system problems. Use the NEXT
softkey to move from one Analyzer
module to another in this screen.

following steps:
1. From the Main Menu, make the following selections: Technical Level
Configurations, Listing of All Modules.
The Listing of All Modules screen
shows all NGA 2000 components
(Analyzer modules, I/O Modules and
Platform [Control Module]) recognized
during the initialization of the network.
Any module connected (or disconnected) after initialization will not be
recognized until the system is reinitialized. Ensure that the system recognizes all modules on the network. If
it does not, the problem must be isolated and corrected before continuing
further.
2. On the Listing of All Modules screen,
ensure that each module has a unique
user tag number. Later I/O modules
will be able to add their slot ID to their
TAG as shown on this screen. If so,
you do not need to otherwise identify
them. It is this tag number that is
used to bind an I/O Module to an
Analyzer module. The user tag number can be set as shown in the example below. For example, in a system
consisting of two NDIR modules, two
FID modules and one CLD module,
the tags could be chosen from Table
1-1.
3. The user tag numbers should be
somewhat logical in their description
to avoid confusion. They should not
contain a period (.) so as to avoid
confusing PC software that attempts
to communicate with the NGA 2000
system.
NOTE
From the Listing of All Modules screen,
the diagnostics of a selected module can
be selected. The I/O Module diagnostics
displays the I/O Module tag number and
allows it to be changed if necessary. To
change the Analyzer module tag number,
however, access the Analyzer Manufacturing Data screen by making the fol-

SAMPLE HANDLING
Rosemount Analytical offers many different
sample handling systems, either assembled or
as loose components. Sample handling is dependent on the requirements of the particular
Installation
2-7
Instruction Manual
760006-A
September 2001
application and the preferences of the individual
user.
Typical sample handling systems incorporate
such components as pumps, valves, needle
valves, flowmeters and filters in order to provide
a clean, dry sample to the Analyzer module.
There are some general sample handling issues
that must be addressed. It must be possible to
control the sample flow into the Analyzers, and
also this flow must in general not be made to
pass through Analyzers in succession, but
rather through them in parallel. The Analyzer
reading is sensitive to sample pressure
changes, so care must be taken to make sure
that such changes do not occur, and that the
span gas pressure is the same as the sample
pressure.
Excessive sample flow can destroy the flow
sensor within the Analyzer module; bring the
flow up from zero, rather than down from wide
open when starting them up.
2-8
Installation
Model NGA 2000 Platform
Solenoid valves used for zero and span gas
control are prone to leaking. If they do so it will
be impossible to get good readings from the
system.
Sample systems must be designed to make it
impossible for water to get into the Analyzer.
Heated sample lines should be heated the entire length, and care must be taken to make
sure that any water dropped out is drained from
the sample line. Unheated lines must slope
down to the Analyzer - water will collect in the
low points and be subsequently entrained in the
sample. The same is true of exhaust lines particularly for the FID Analyzers. It must be
impossible for condensate to freeze or flow back
into the Analyzer, or provide a slug of water
whose effect will be to provide pressure
changes as the bubbles go through it.
There are many such issues. Sample system
design is rather an arcane skill, and it is worth
having an experienced person or company design such a system. Most Analyzer problems
are in fact sample handling system problems.

menu instructions. Operation is performed
with five function keys, four arrow (cursor)
keys and the enter key. The function of each
key varies depending on the installed Analyzer module, any auxiliary modules installed,
and the individual menu displayed.
OVERVIEW
The Platform can perform a narrow set of active functions within the NGA 2000 Series
range of operations. That set of functions includes the following:
In case of power failure, all user defined specific module parameters are saved by a battery powered memory.
• Supply power to a single internal
Analyzer module, and any integral I/O Modules, if equipped
with an integral power supply
Function Keys - Also called softkeys, are
assigned values depending on the menu or
screen being displayed. The legend is displayed above the keys.
• Output data to the front panel
display
• Hold and maintain network configuration data
Enter Key - Used to confirm a previously entered variable value, to start a selected function or to go to a submenu selected at a menu
line as opposed to the Function Keys. As an
alternate to using the Enter Key to start a
function, the → key can be used.
Most other functions are performed by other
modules. For instance, the Analyzer module(s) performs all functions related to gas
concentration measurement, and therefore
places on the network all related data. This
data (which appears on the Run Mode, Menu
and Diagnostic display screens) is Analyzer
module-specific. Refer to the respective Analyzer module instruction manuals for descriptions of those operational functions. Multiple
Analyzer module systems require an additional source of 24 VDC power.

Cursor Up/Down Keys (↑ or ↓) - Used to
move up or down the lines within a menu or to
increment and decrement number variables.
Cursor Left/Right Keys (← or →) - Used to
move backwards or forwards between the
pages of a menu or to select numeric digits for
adjustment.

This module detects NO by reacting it with ozone and
measuring the light produced. It can reduce NO2 to NO and
tthen measure the total amount of NO, this measurement is
called NOx. It uses a converter to do this, and it makes its
own ozone with an ozonator. It is vital that the temperatures
of these are correct. It is necessary to replace the converter
periodically.

STARTUP & INITIALIZATION
(C) 2001 FISHER-ROSEMOUNT Analytical
1. Check the sample system operation, and
make sure that flows are correct. Be
careful not to destroy the Analyzer flow
sensor with excessive flow (maximum 2
l/min).
NOTE
Ensure that all flow and pressure
settings are at or below their recommended values before applying
gas or power to the Analyzer modules. Instrument damage can occur
if maximum values are exceeded.
2. Check the power connections, and LON
connections, and power up the system.
Do not initiate any PC LON software yet.
3. The Platform should interrogate the system, and build its database. See the NGA
2000 Reference manual for troubleshooting information if anything goes wrong.
4. Apply power to the NGA 2000 Platform by
plugging it into a power source. The Platform has no ON/OFF power button. Once
power has been supplied to the Platform,
any connected Analyzer modules will be
energized.
5. After switching on the CLD, the Analyzer
will begin its booting procedure which is
apparent on the LCD screen. The first
part of the initialization procedure is a self
check of the software and Analyzer components. Various displays will show the
status of the initialization including revision notes.
6. If the user's system contains only one
Analyzer module, all system components,
the Controller Board and the network
"self-install" (bind together) during initial
startup. If the system contains more than
one Analyzer module, the startup sequence will interrogate the network to locate and identify all components on the
network. The user will have to bind appropriate combinations of components
after the startup sequence. See Section
2-6 for instructions on binding combinations of modules.

7. Pressing the F1 key during initializing will
reset the LCD brightness and contrast to
factory settings (See Section 3-6c).
Pressing the F3 key will abort the network
initializing, aborting any connection to
other Analyzers. In that case, only the
menus of the local Analyzer will be available.
8. At the end of the initializing routine the
“measure” screen will display. This screen
is the access to all other channels, menus
and submenus. The actual display may
differ from that shown depending on any
custom configuration as described in
Section 3-5.
9. Check that the Platform has found all the
Analyzer modules and I/O modules, and
all have been correctly bound. Systems
are normally provided already setup, but if
not done, bind the I/O modules to the
Analyzer modules using the procedure
outlined in the NGA 2000 Reference
manual.
10. Set up any PC interface components.
11. Verify the operation of the Analyzer modules on zero and span gases, and then on
the sample itself.
12. Verify the Analyzer module linearity on
mid-scale span gases.
13. Verify the operation of the sample system.
14. After the warm-up period (about one hour
for most Analyzer modules), all modules
are completely functional.

ROUTINE OPERATION
Once an NGA 2000 system has been properly
installed, it will need little attention. The Analyzer modules will need to be calibrated at intervals, and the sample system will have to be
maintained. Calibration gas information will
have to be entered into the Calibration gas
menus for each Analyzer module whenever
gas bottles are changed.
Calibration information is given both in the
Analyzer modules manuals and in the NGA
2000 Reference manual.
Certain Analyzer modules require periodic
maintenance: CLD Analyzer modules need
new converter material and occasional ozonator replacement; FIDs need their flame
towers cleaned; NDIR Analyzer modules require periodic sample cell cleaning. See their
appropriate manuals for details.
It is possible to use several means of making
digital communication between the NGA 2000
system and a PC. This communication can be
via AK or Modbus over RS 232 or RS 485, or
directly over the LON. Using any of these the
PC may be setup to control the operation of
the system, and to download calibration information as desired.
If an NGA 2000 component is changed out,
the Platform and also the PC interface must
be told about it. The simplest way to tell the
Platform is to power it down and back up
again. It will re-interrogate the network and
load the new component into its database. If it
runs out of memory during this operation, it
will hang, and you will have to reset it, and
then rebind everything. See the NGA 2000
Reference manual for details.
A PC LON interface will also have to be reset;
AK and Modbus will have to be re-addressed
also due to the change in the database.
a. Correct Operation
The following is a summary of what you
should expect from an NGA 2000 system.
3-8
Operation
Model NGA 2000 Platform
The response of the screen to user inputs
- such as changing menus or editing variables –should be immediate, with new
menus appearing well within one second.
The main reading should show stable
numbers on zero or span gas, except at
its lowest range where the 1% of range
noise level may be noticeable. Analyzers
should hold their calibration to at least 1%
of range per day (see their specifications
for details on this).
There may be a perceptible delay in indication of secondary values, such as flow
and pressure. Some of these may take as
much as five seconds to be reported.
Analyzer flow rates should be stable and
should be controlled similarly on zero,
span and sample. The Analyzer module
should respond to its span gases at its
specification (depending on its filter settings), but bear in mind the exponential
time response and allow ten time constants for real stability.
The main screen will wash out in direct
sunlight, but it should be bright enough to
read in complete darkness or ordinary
room light.
Analyzers should warm up within about
an hour, and should show stability within
one day, other than Trace O2s or FIDs
which have special considerations.
Analyzers should show no sign of wetness in their sample tubing. FIDs will
show water condensate in their exhaust.
Analyzers should not be too hot to touch,
except possibly for heated FIDs.
There should be no perceptible stepping
on the trace of a chart recorder from an
I/O module (as normally configured).
The system should remember how it is
configured no matter how it is powered up
or down, and it should always be possible
to enter any module’s menus.

Model NGA 2000 Platform
It is normal for a Platform to run out of
memory if it is given too many Analyzer
modules to deal with, or Analyzer modules are replaced too often without resetting it. V2.2 Platforms can deal with about
6 Analyzer modules, and V2.3 or later
with about 10 (when used with the increased RAM Platform Controller board).
The symptom of this is that the Platform
hangs up while starting up, or continuously restarts itself. In this case, you need
a hardware upgrade, and should call
Rosemount Service.

BASIC CONTROLS, SETUP AND STATUS
The following sections describe the basic
control of the NGA 2000 Platform and any installed Analyzers. Examples of stepping
through the menus are shown so that the user
can become familiar with the operation,
keeping in mind that displays and menu
choices may be different depending on the
configuration and any customization of the
menus.

SECTION 4
SYSTEM SIO MODULE
4-1
• Optional sub-modules to provide
4, 6, or 8 analog outputs as described above.
OVERVIEW
The SIO module is an optional card that plugs
into the platform. Since it is not part of the
LON network, it does not require binding but it
must be configured to assign the desired
Analyzer module and module signal to the
various outputs. Only one SIO module can be
installed per platform. The SIO module is
available with 2, 4, 6, or 8 channels of analog
output and a serial interface (RS-232 or RS485) and relay contacts.
• Optional RS-232 or RS-485 (Rx,
Tx) output sub-modules.
• Three configurable relays
(SPST) rated at 30V / 1A / 30W
maximum.
The analog outputs can be assigned to the
various signals from any Analyzer module
connected to the Platform. The relays can be
assigned to various discrete signals from any
Analyzer module connected to the Platform.
The system SIO module is a circuit card that
plugs into the rear of the Platform. The functions provided are as follows:
• Dual channel analog output provided as both a voltage and a
current. The voltage output is
configurable as 0-10V or 2-10V
(load > 2KΩ). The current output
is configurable as 0-20mA or 420mA (impedance 500Ω).
The RS-232 or RS-485 outputs can be used
to communicate from any Analyzer module
connected to the Platform to peripheral devices.
Since the SIO module is not a LON module, it
is not bound to the Analyzers.

OVERVIEW
The DIO module is an optional card that plugs
into the platform. Since it is not part of the
LON network, it does not require binding but it
must be configured to assign the desired
Analyzer module and module signal to the
various outputs. Up to 4 DIO modules can be
installed per platform. Each DIO module contains 24 assignable digital outputs and 8 assignable digital inputs.

SYSTEM CALIBRATION MODES - OVERVIEW
System calibration can be established in one
of two modes or disabled.
Interval Operation
Interval calibration allows the setting of an
“Start of interval time” which is the time of day
for the interval calibration to occur, and an
“Interval time” which is the number of hours
between each calibration event in the range of
1 to 10,000.
Interval calibration can perform basic Zero
and Zero/span calibration.
Interval calibration can also be used to establish and interval for a “Sequence Programmed” calibration.
Sequence calibration programming allows for
the setup of up to 40 program sequences for
various calibration functions of up to 4 bound
Analyzer modules. The programmed sequence can be initiated by the “Interval” operation or manually.
Disabled
If Interval and Sequence calibration is disabled, no automatic calibration will occur but
manual calibration can be performed from
each individual bound Analyzer module using
the “Calibration and test procedures” menu.
Calibration Test
The calibration test function allows the testing
of the calibration by flowing gas to an Analyzer and viewing the results.
Before setting any parameters, make sure the
system clock is set correctly. This is to be
found in Section 6-6, page 6-7.

The Program Cal is set to start at hour 20 with

on the following day.
AUTOCALIBRATION INTERVAL OPERATION
In the example shown in Figure 6-2, the system time is 17:00:00 May 29, 2001.
Start of interval time: is the time of day the
event is to occur in the range of 0 to 23.
Therefore, the Zero Cal is set to start at hour
1 with an interval of 24 hours will next occur at
1 AM on the following day.
Interval time: is the desired interval between
calibrations in the range of 1 to 10,000 hours
(up to 416 + days).
The Zero & Span Cal is set to start at hour 7
with an interval of 48 hours will next occur at 7
AM on the second day.
If the start of interval time is prior to the current system time, the event will first occur at
the nearest start time plus the interval time.

MODULE BINDING
This series of menus under Network Module
Management are used to manage the binding
of Modules to the Platform and between Analyzers and I/O Modules.
Binding will occur automatically if only one
I/O board and one Analyzer module are on
the system. Multiple Analyzers modules and
sharing of I/O boards with Analyzers will require binding. Once bound, the binding configuration is retained in platform memory and
binding will occur automatically if the platform
in powered down. However, if modules are
changed, the procedures below need to be
performed to replace or add bindings into the
memory.
In the List of Active Modules display, listed are
the currently active modules connected to the
Platform recognized during the initialization of
the network.
NOTE
Any module connected or disconnected after initialization of the network will not be recognized until the
system is re-initialized. Ensure that
the system recognizes all modules
on the network. If it does not, the
problem must be corrected before
continuing.
6-12
System Configuration and Diagnostics
Ensure that each module has a unique user
tag number. See Section 2-6d for further instructions
NOTE
.Binding refers to linking an Analyzer to the Platform or an I/O board.
Adding refers to binding an I/O
board to more than one Analyzer.
To change an I/O module assignment:
Hghlight the module to be changed and press
the F3 (Delete!) button on the Module Binding
menu. Then assign the I/O module to another
Analyzer as previously described.
To remove an I/O module:
Delete can also be used to remove an Analyzer module that is no longer attached to the
platform or to remove an I/O module from an
Analyzer module.
When all assignments are complete, press the
F4 (Bind!) key. The system will re-initialize,
binding all the modules as chosen. To cancel
the assignments before performing the bind,
press the F1 (Abort) key to return to the Main
Menu.

TROUBLESHOOTING
8-1
SYSTEM TROUBLESHOOTING
Most Analyzer module problems stem from
sample system issues. A lot of these are addressed in the NGA 2000 Reference Manual,
and in the Analyzer module manuals themselves.
The NGA 2000 Reference Manual also contains operational details that should assist you
to diagnose faults not covered in this present
section or the Analyzer manuals themselves.
Each section of the NGA 2000 Reference
Manual contains specific troubleshooting tips.
This section will simply try to point out the
area of concern for a given symptom.
Platform hangs up on start up
Out of memory. Reset it. See System Setup
in the NGA 2000 Reference Manual. Also,
not enough RAM for a large system. Use the
Controller board with RAM expansion. Also,
an Analyzer module may have lost power or
connection during the initialization process.
Power down the system and try again. Check
each Analyzer module with the Platform one
at a time to see which one hangs up the system.
Can’t enter menus
Network error or module gone dead (or an
earlier than V2.2 I/O Module). Check for
power failure for an absent module, bad connection, or failed module. Upgrade an early
I/O Module. Also, excessive network traffic.
Reduce update rate - see the NGA 2000 Reference Manual section titled Response time.
If the LON length is greater than about ten
meters, make sure that you have LON terminations in place.
Platform shows “No Data”
Analyzer module no longer responding.
Check its LON connection, power connection,
power fuse.. Open it up and see if the red
LED’s on its Analysis Computer Board are on
Rosemount Analytical Inc.
A Division of Emerson Process Management
or blinking. If so, power it down and back up,
and if it still doesn’t communicate, replace the
board or the entire Analyzer module. Try
connecting the bad Analyzer module by itself
to the Platform using a new cable.
No analog output, or wrong output
Check the binding of the I/O module, and
check that you are monitoring the correct one.
In its diagnostic menus, check the analog output of the I/O module. If it is reported as being OK, the problem is in the wiring or in the
recording device. See I/O module section.
Calibration problems
See the calibration I/O module sections of this
manual, and the zeroing and spanning sections of the NGA 2000 Reference Manual.
Analyzer stability problems
Check the Analyzer module power and
grounding, the ambient temperature, and the
sample system. Check for ambient gas interference - CO2 in the atmosphere, etc.
Check the exhaust pressure stability. Generally make sure that the environment is satisfactory before assuming that the Analyzer
module is at fault. See the NGA 2000 Reference generally, and the Analyzer module
manuals in particular for further hints.
Analyzer Linearity Problems
See the appropriate sections in the NGA 2000
Reference manual.
User programmed data is lost after momentary power loss to Platform
The Controller board in the Platform uses a
long life lithium battery to maintain user programmed data in the event of a power loss.
The battery voltage must be 3.38 VDC or
greater for proper operation. If the battery
voltage is less than 3.38 VDC it must be replaced by qualified service personnel or the
Controller board replaced by the user.

the older versions of the Platform.
11-1 SMART I/O MODULES
a. Analog I/O Module
Overview
Refer to Section 2.6 for instructions on
how to install the Basic Analog I/O Module and Section 2.9 on how to bind the
Basic Analog I/O Module.
Software V2.0, V2.1 and V2.2 Analog I/O
Modules provide an analog output signal,
up to three alarm contacts, four contacts
that are used to indicate the current range
of operation of its associated Analyzer,
and six digital inputs, of which four are
used to determine which range to use.
V2.3 and later allow the user to configure
all of the relay outputs and digital inputs to
whatever functionality is desired.
In V2.3, special software allows the I/O
module to track the special functions supported by the Analyzer, and to show on its
control screens whatever the Analyzer
can provide or accept in the way of digital
indication or control. Any of the relay outputs or digital inputs can be assigned to
any function that the Analyzer can support.
NOTE
V2.2 Platform software only supports
V2.2 I/O Modules. V2.3 Platform software supports both V2.2 and 2.3 I/O
Module software, but only V2.3 I/O
Module software has the special features mentioned here.
Rosemount Analytical Inc.
A Division of Emerson Process Management
The analog output signal is bound to the
Analyzer’s PVA variable, i.e. its main output reading. The analog output is scaled
to the current operating range (or to a
specific operating range if desired). It may
be connected as either a voltage output
(0-5V) or as a current output (0 or 4 20mA). In any case both the zero and
span are live, which is to say that the output can go below the zero point or above
the fullscale point.
There are three SPDT relay outputs which
can be used as alarms. SPDT refers to a
type of relay which allows connection to
the Common (C), Normally Open (NO)
and Normally Closed (NC) contacts.
These designations refer to the state of
the contacts when the relay is unpowered.
In V2.2 and earlier, four more SPST relay
outputs are used to indicate the active
range of the I/O module. This is normally
the same as the range used by the Analyzer, unless the user has chosen to operate the I/O module on a constant range.
Only one of these relays will be energized
at one time. These relays may retain this
function in V2.3, or they can be reassigned to other functions.
There are also digital inputs that may be
used to control which range the I/O module or Analyzer is on. In V2.3 they may be
made to control any specific functionality
supported by the bound Analyzer, such as
to light the flame in the case of the FID.
NOTE
Use the path Analyzer and I/O Expert

• Validity
Alarm Description – v2.2
Concentration alarms respond to the
Analyzer primary reading, its measured
gas concentration. The alarm can be set
to trigger above or below a set point, and
the relay can be set to operate in normal
or fail-safe (powered when in the normal
state) operation. The set point may be
expressed either as an absolute value, or
as a percent of the current range, in which
case the concentration at which it alarms
will depend on the range.
This section describes the alarm capability in V2.2. V2.3 added some significant
features which are described in the next
section.
There are three alarm relays each of
which may be programmed to respond to
any of the following categories.

COMMENTS
Concentration
Programmable high/low, fail-safe/normal.
Warning
Tied to Analyzer WARNING alarms, if Analyzer alarm reporting is enabled.
Failure
Tied to Analyzer FAILURE alarms, if Analyzer alarm reporting is enabled.
System Failure
Loss of communication with any module in the system.
Control Status
Shows that remote control of range inputs is enabled.
Validity
Valid if: Analyzer operational state is normal; last span and zero did not fail, the
Analyzer is looking at the sample gas (not a calibration gas), no internal Analyzer
alarms are reported, the sample flow is greater than the lower limit, and the detector
temperatures are within limits (except for the CLD). There are other Analyzer specific problems which may affect validity also, such as flame out in a FID.
Table 11-2. Alarm Relay Configuration Matrix (v2.2)
Concentration
Can be expressed as a percentage of the
current range or as an absolute value of
gas concentration measured. Alarms can
be set to alert the user of low concentration, high concentration and percent of
range values.
Warning
Indicates one or more softwareconfigured limits on any network variable
(other than gas concentration) has been
exceeded. Examples of these secondary
variables are flow rate and internal voltage. A software reset or other resolved
software failure would also be reported.
In the event of a Warning alarm, gas concentration values displayed on the Operator Interface or present on output lines
may not be accurate.
Failure
Indicates an unrecoverable hardware or
software failure such as some component
not responding to network communications or a safety related failure such as
lack of purge air in a Flame Ionization
Detection Analyzer module.
Rosemount Analytical Inc.
A Division of Emerson Process Management
In the event of a Failure alarm, gas concentration values displayed on the Operator Interface or present on output lines
will not remain accurate.
Control Status
Indicates that the Analyzer control has
been set to remote, in which case the input lines on the I/O module are enabled.
Validity
Describes a condition in which gas concentration values present on the Operator
Interface or output lines should be considered invalid. The Analyzer module
alerts the system that an error in gas concentration is present. Causes include failure or lack of calibration, flame out in a
FID, or a not-from-process gas applied by
a sample control module.
The Analog I/O Module has the capability
of tracking a set range regardless of
which range the Analyzer module is on. It
is therefore possible to use several Analog modules bound to one Analyzer to
provide multiple outputs at the same time.

Installation
If the Analog I/O Module is received as a
separate unit, carefully examine the shipping carton and contents for signs of
damage. Immediately notify the shipping
carrier if the carton or contents is damaged. Retain the carton and packing material until all components are operational.
To install the Analog I/O Module, perform
the General Procedure in Section 2-6.
Bind the Analog I/O Module to an Analyzer module as detailed in Section 2-6e.

failure: — if the Analyzer dies, do
you want the output to go to zero,
fullscale, or hold its last value? This
could have safety implications.
8. Select whether the output holds its
value when any of the three alternatives shown happens. If the reading
becomes invalid, if a calibration is
underway or if the menus are entered (maintenance), you can make
the output hold its last value. This
may be undesirable, so consider
this carefully.
Perform the procedures in Section 11-2.

In this screen, Trips as % of range or
absolute: is whether to alarm as percentage of range or on absolute values. If the former, the alarm set point
will change with each range. If the
latter, there will be a single alarm
point, no matter what range is selected.
7. Select Hysteresis:. This is the difference between the “on” point and the
“off” point, expressed as a percentage of the on point. E.g., in the case
of a high alarm, if the alarm is set at
80ppm, it will trip when the reading
goes above 80ppm. When it comes
back down if the hysteresis is set to
10%, the alarm won’t go back off
until the reading gets below 72 ppm.
The 10% default is usually satisfactory.
8. Select the Delay till alarm actuates:
This adds a time delay, preventing
nuisance alarms on short term
spikes in the reading.
9. Set the alarm level in either absolute
or percentage of range. You can
select both, and then the alarm set
point will perhaps change as you
select whichever mode you want.

Analog I/O Module Calibration
Procedure
Perform the Output signal zero and span
calibration procedures as follows:
3. In the I/O Module Analog Output Diagnostics menu, choose Voltage
output calibration… or Current output calibration… , depending on
output requirements.

menu by making selections in the
following path: Main Menu, Technical Level Configuration…, Diagnostics…, [choose] Analog I/O
[module], Analog output module…
Current output calibration…
IO module ID:
Analog output Parameters…
Select Voltage or current:
2. To perform both the zero and span
calibration procedures, the operator
must use output values obtained
from a calibrated digital voltmeter or
other sensing device connected to
the I/O Module output. The Measured values shown by the I/O module itself are not accurate enough to
calibrate the output circuitry.
4. Choose Test on the Set to test for
calibration: line.
5. If the operator is performing a Voltage Output Calibration, do steps 6
through 9. If the operator is performing a Current Output Calibration, do steps 10 through 13.
6. Voltage calibration: perform the zero
calibration procedure first. Set the
Desired output voltage: to 0.
7. Observe and record the output
value.

8. Adjust, if necessary, the output
value by scrolling the Zero offset:
until the output value is 0.
9. Perform the span calibration.
Change the Desired output voltage:
to 5, and scroll the Gain Factor until
the output value is 5. Skip the remaining steps.
10. Current calibration: perform the zero
calibration first. Set the Desired output current: to 0 (no matter whether
the module is set to operate on 0 20 mA or 4 - 20 mA).
11. Observe and record the output
value.
12. Adjust, if necessary, the output
value by scrolling the Zero offset:
until the output value is the zero
value (0 mA).
Perform the span calibration procedure.
Change the Desired output current: to 20,
and scroll the Gain factor: until the output
value is 20.
After completing the span calibration procedure, the operator should recheck and
readjust, if necessary, the zero calibration
values.
NOTE
The measured output current or voltage is not measured with enough precision to do more than tell you whether
the output circuit is working or not.

put. On the other hand, if it does show
a value, but you don’t detect one in
your monitoring device, it means that
either the output connector, or EMC
components on the I/O module are
bad, or there is an error in the wiring.
The measured signal does in fact
measure the output signal, it is not
merely calculated from the value the
output is supposed to be putting out.
Analog Output Over / Under
Limits
The analog output can be configured with
live zero/span or “clipped” zero/span by
setting the over limit and under limit of the
voltage or current output signal.
In the I/O Module Analog Output Diagnostics menu, select Diagnostic limits
(see Section 11-2). There will be various
current and voltage limit selections to
choose from. Edit the appropriate set of
over and under limit values that pertain to
the analog output you have selected.
The minimum current under limit is –2.0
and –6.0 while the maximum current over
limit is 25 mA. The minimum voltage under limit is –90 V and the maximum
voltage over limit is 10.0 V.
Setting the under limit and over limit values is essentially setting the minimum
and maximum signal output.
The analog I/O Module is now fully operable and read for use.

gas concentration value is updated instead of held.
If Output hold on maintenance: is enabled
and the state of the Analyzer module is
either maintenance or standby, the last
gas concentration value measured during
the valid state is held and output from the
I/O Module. When the Analyzer module
state returns to valid, the gas concentration value is updated instead of held.
If Output hold on calibration: is enabled,
three selections are available; Disabled,
Enabled and CEMS. These selections
operate as follows:

If Disabled, the gas concentration value
is updated while the Analyzer module is in
the calibration state.
If Enabled, and when the Analyzer module is in the calibration state or the QC
check state, the last gas concentration
value measured during the valid state is
held and output.
The three "Output hold..." selections on
the Analog output Parameters menu refer
to the I/O Module capacity to maintain or
hold the output of the gas concentration
value despite a change in the state of the

If CEMS, and when the Analyzer module
is in the calibration state, the gas concentration value is updated throughout the
zero and/or span cycles. The calibration
factors are held until the calibration cycle
is over. Therefore the output responds to
the reading of the calibration gases using
the factors from the previous calibration,
as if the Analyzer were simply measuring
them rather than calibrating itself. Only
when the calibration cycle is over does
the Analyzer use the new calibration factors. This allows the user to determine
how much drift has occurred.

Analog I/O Module Range Control Discussion
The whole question of ranges in the NGA
2000 system is rather complex. Analyzers
themselves support four ranges, but these
are mostly software considerations only,
and mainly result in the application of different calibration and linearization parameters to the same sensor signals.
Certain Analyzers do make hardware
changes as a result of range changes,
and these are described in the appropriate manuals and the NGA 2000 reference
manual.
The Analog I/O module can be made to
track the range of operation of the Analyzer, or to operate independently of it. It
can also control the range of the Analyzer, either automatically or as a result of
external input through the digital input
lines.
If the module is made to control the operation of the Analyzer, allowance must
be made for the delay associated with the
LON communication system. It may take
as much as a second for the Analyzer to
respond to an external range change re-

quest. During this time the reading may
not relate to the requested range. Any
control system relying on an instantaneous range change will produce an error
during this time.
If this fact cannot be dealt with in the control system software, the Analog I/O module should be set to operate
independently of the Analyzer. In this
mode, the output scaling corresponds to
the range requested by the digital input
line, but the Analyzer's range is not affected. As long as the Analyzer's range is
wider than those of the Analog I/O module, the system will operate correctly, except that of course any specific calibration
or linearization performed on the other
ranges by the Analyzer will not be used.
In this case the response time to a requested range change by a 2.3 V Analog
I/O module will be variable but always
less than 100mSec, typically 40mSec.
The preferred solution, of course, is to get
the output of the Analyzer directly from
the LON, where these considerations do
not apply, and the Analyzer can be operated on one or several ranges as desired.

b. Single Analyzer Analog Autocal I/O
Module
Description
Refer to Section 2-6 to install Single Analyzer Analog Autocal I/O Module and
Section 2-6e to bind the Single Analyzer
Analog Autocal I/O Module (also known
as the Single Analyzer Analog Autocal I/O
Module).
• Relay 2 - zero gas: closed when the
zero gas should be flowing.
• Relay 3 - calibration in progress: closed
when any zero, span or calibration cycle
is being executed.
• Relay 4 - span gas 1: closed when span
gas 1 should be flowing.
• Relay 5 - span gas 2: closed when span
gas 2 should be flowing.
The standard calibration procedure in the
Analyzer module Menu Structure (under
“Basic controls”) is not automatic. When
you press “ZERO” or “SPAN”, the Analyzer assumes that you are flowing the
appropriate gas. It does not itself change
any gas flow, nor does it communicate to
the Autocal module described in this or
the next section.
• Relay 6 - span gas 3: closed when span
gas 3 should be flowing
The Single Analyzer Analog Autocal I/O
Module allows the user to either manually
or automatically perform the calibration
procedures for the Analyzer module. The
calibration procedures can be either initiated manually or automatically.
• Line 2 - do span on the selected range
The Single Analyzer Analog Autocal I/O
Module also provides analog signal outputs. Up to four span solenoid valves and
one zero solenoid valve (customer supplied) can be energized at set time intervals. The frequency and duration of the
calibration cycle is software programmable, allowing many varied sequences, a
few of which follow:
• Relay 7 - span gas 4: closed when span
gas 4 should be flowing
The Auto Calibration Module has six
digital input lines for remotely initiated
calibration. The function of each line:
• Line 1 - do zero calibration
• Line 3 - do a zero and/or span, as programmed
• Lines 4 & 5 - select the desired range in
binary fashion (for Line 2 above ONLY).
See Table 11-5.
• Line 6 - disables calibration instruction
and allows only a check to occur

Installation
If this I/O Module is received as a separate unit, carefully examine the shipping
carton and contents for signs of damage.
Immediately notify the shipping carrier if
the carton or contents is damaged. Retain
the carton and packing material until all
components are operational.
To install this I/O Module, follow general
installation guidelines in Section 2 and
then do the following:
Autocalibration Sequence
Setup - Overall Timing
The calibration sequence is; wait until the
calibration time; indicate a calibration sequence; purge with zero gas; tell the
Analyzer to zero itself; wait until it says it’s
done; purge with the first span gas; tell
the Analyzer to change range (if necessary); tell the Analyzer to span this range;
wait until it says it’s done; purge with the
next span gas and repeat up to a total of
four spans; purge with sample gas; indicate the calibration sequence is over.
Before setting these parameters, make
sure the system clock is set correctly.

Set the day of the month, and the time of
day to start the calibration sequence. The
unit will automatically calibrate thereafter
at a suitable period set below. Make sure
you have chosen a day and time in the
future! Otherwise it will wait a month.
Set the calibration cycle period. This is
the length of time it will wait between calibrations. 24 hours is traditional, but it can
be programmed up to 255 hours. You can
set it to zero at this period, but to span
only every so many zeros, see below.
Set the zero gas dwell time. It should be
long enough that the Analyzer reaches a
good stable zero point. If in doubt make it
longer.
Set the span gas dwell time. This has to
be long enough for the Analyzer to become stable at the span point. This time is
normally shorter than the zero time.
Set the sample gas dwell time. This is the
time it will wait after its last span before
releasing the “In Calibration signal” (either
the relay or the PROCESS variable). This
time should be long enough to allow the
reading to get to within its error tolerance
of the actual reading, normally shorter
than the other two times.
Set the control status. This module can be
slaved to another Autocalibration module,
or it can be a master for a group of two or
more such modules, or it can be independent of them. If it is a master, it will
make all the other slaves start a calibration when this one does: if a slave it will
wait until it is told to calibrate before doing
so. If independent it will ignore any other

3. Select Zero gas valve...
NOTE
Only the start time is common to master/slave groups. Because of the differing times taken by the Analyzer
modules over their zero and span functions, the spans and the end times will
probably not occur simultaneously.
This means that in general you cannot
use a single span gas valve for multiple Analyzers when using multiple single-Autocalibration modules. Use the
system Autocalibration module instead.
In the Timing parameters screen, the
following should be considered: If

month is 0, calibration will occur every
day and If Calibration cycle period is 0,
auto cal is disabled.

c. System Autocal I/O Module
Description
The System Auto Calibration I/O Module
allows the user to automatically calibrate
up to four Analyzer modules at once. A
typical application would be a CEMS-type
calibration for all Analyzer modules at
once, in sequence or in varied combinations.
Model NGA 2000 Platform
• Relay 2 - zero gas: closed when the
zero gas should be flowing.
• Relay 3 - calibration in progress: closed
when any zero, span or calibration cycle
is being executed.
• Relay 4 - span gas 1: closed when span
gas 1 should be flowing.
• Relay 5 - span gas 2: closed when span
gas 2 should be flowing.
Four calibration cycles (software configurable) can be executed:
• Relay 6 - span gas 3: closed when span
gas 3 should be flowing.
• Manually-initiated zero cycle
• Relay 7 - span gas 4: closed when span
gas 4 should be flowing.
• Manually-initiated span cycle
• Manually-initiated auto calibration cycle
(zero and up to four span functions)
• Time-initiated auto calibration cycle
(based on the network's clock)
Up to four span solenoid valves and one
zero solenoid valve (customer supplied)
can be triggered at set time intervals. The
frequency and duration of the calibration
cycle is software programmable, allowing
many varied sequences, a few of which
follow:
• zero x times, then span
• zero, then span
• zero, span, then check on a midpoint
Four SPST and two SPDT relays are
used to drive solenoid valves that control
the flow of zero and span calibration
gases to the Analyzer modules. The seventh relay indicates an in-calibration condition on the network. Here are the relay
output definitions:
The System Auto Cal Module has six
digital input lines for remotely initiated
calibration. The function of each line is the
following:
• Line 1 - do zero calibration on current
range as setup in the Analyzer module
• Line 2 - currently unused
• Line 3 - complete up to four (4) cycles,
as programmed
• Line 4 - local/remote selection: 0 = local,
1 = remote (used to set the dwell times
for gases)
• Line 5 - currently unused
• Line 6 - Calibration or QC check: 0 = as
setup in the Auto Cal Module, 1 = QC
check only
After calibration, the output signal is then
corrected for zero and span. The System
Auto Cal I/O does not provide an analog
signal output. (See Table 11-7 for a complete list of functions.)
• Relay 1 - sample bypass: closed when
the sample should not be flowing
through the Analyzer module.

11-2 EXCEL-BASED PC INTERFACE
Excel-Based PC Interface Description
NGA 2000 PC Interface packages consist of
software and hardware elements that allow
communication between NGA 2000 components and a personal computer (PC). These
packages allow the user bi-directional or readonly communication with commercially available software or Rosemount operating software for the PC Workstation package.
The Excel-based PC Interface is a package
that uses Microsoft Corporation's Excel
spreadsheet software for its interface functionality. It has bi-directional capabilities (i.e.,
it can place as well as read data on the network).
The PC Interface addresses the network
through the network port (the I/O panel labeled LON MODULE, which is usually located
in the I/O slot nearest to the Analyzer module
opening in the Platform's back panel), and
achieve data transfer through Echelon's
LONWORKS communication protocol.
PC Interfaces have access to all network variables. Due to its bi-directional nature and
based on the power of the Excel software, the
Excel-based PC Interface can carry out many
standard I/O Module functions like setting
alarms and triggering calibration functions.
Through Excel’s functionality, you can create
custom screens that display data in groupings
specific to your application.
Excel-Based PC Interface General Requirements
PC Interface Packages support operation of
the complete line of NGA 2000 products including all of the Analyzer modules, and it
also allows reading of Platform and I/O module variables.
It does not support operation with nonRosemount Echelon based devices; however
the Rosemount DDE server itself does emulate the operation of the Echelon DDE server,
11-26
Appendices
allowing upgrading systems designed around
the latter.
Excel-Based PC Interface Software Requirements
PC Interfaces require Microsoft MS-DOS V5.0
or higher, Windows V3.1 or 95, and Excel
V5.0 (all supplied by customer). Note it does
NOT support Windows NT™!
PC Interfaces also require the Rosemount
DDE Server driver software, the Serial
LONTALK Adapter (SLTA) driver (or the single channel PCLTA and driver) (all supplied
by Rosemount Analytical).
Excel-Based PC Interface Hardware Requirements
The minimum PC hardware required to support this package consists of an IBM compatible, Pentium PC with 32 MB RAM, a 4 GB
hard drive (all supplied by customer) and one
available COM port. For optimal performance,
64 MB RAM and 6 GB of hard drive space is
preferable. PC Interface software occupies up
to 10 MB of hard drive space. Lengthy Excel
logging spreadsheets can easily occupy many
tens of megabytes.
The LONWORKS gateway hardware is an
Echelon Model 73000 Serial LONTALK
Adapter (SLTA). This device provides communications between the NGA 2000 digital
network to the PC.
An alternative device is the Echelon PCLTA
ISA bus internal LONWORKS adapter.
A router device, the Echelon Model 71000
Router, is required when more than one NGA
2000 Platform is interfaced to a single PC
(one router for each Platform). This will eliminate conflicts with node assignments between
Analyzer modules and their respective Platforms. This device requires the use of some
specialized software which is available from
Rosemount (MAKE_API.EXE and
SET_LOCN.EXE).

tions are chosen, the program will set itself up in a directory called “NGA
2000SUITE”. Under this directory will be a
“DOCS” and an “EXAMPLES” directory.
Under the latter will be an “EXCEL” directory.
NOTE
The SLTA's PC communications setting is normally COM1. Some PCs
assign COM1 to a mouse or other
pointing device. If this is the case,
the user must manually change the
following item in the PCs CONFIG.SYS file to reflect another available COM port (typically COM2):
DEVICE=C:\ECHELON\BIN\LDVSLTA.S
YS /pn /d1 /a
where /pn is the option switch that
determines the device's COM port, n
being the port number. Valid port
numbers are 1 through 4. For additional information, refer to the SLTA
instruction manual. Using an editing
software, change the CONFIG.SYS
file to an appropriate setting.
6. When it has finished, the DDE server will
minimize itself. If desired, open it by double clicking on its icon at the bottom of the
screen, and click on File in it. Select Nodelist… to see which nodes were found.
7. If desired, edit the node location or TAG.
If you change the TAG, the Excel spreadsheets (which use the TAG to identify
Analyzers) will not work, so exit the DDE
server and restart it to refresh the now
changed database.
8. Start the Microsoft Excel program.
9. Open the Excel example worksheet file:
NGA 2000LOG.XLS in the EXCEL directory under EXAMPLES.
10. Press the “Record Data” button on the
Variable Select sheet. Answer all the
prompts as desired.
11. Open the other Excel example worksheet,
NGA 2000CHECK.XLS, NGA
2000PARMS.XLS and NGA
2000TREND.XLS, found in the EXCEL directory. Press the “Analyze Network”
button on these, and follow the directions.

ers, it is not bound to the Analyzers in the
same way.
Description
The Local I/O module, also called an SIO
board, is a circuit card that plugs into the rear
of the Platform. However unlike the other I/O
modules it itself contains no processing
power, it merely allows the computer in the
Platform to control various I/O functions.
The functions provided are as follows:
• Dual channel analog output
• Optional analog output submodules for up to eight channels
• RS-232 or RS-485 optional output sub-modules
• Three programmable relays.
The analog outputs can be assigned to one of
many optional readings from any Analyzer
module connected to the Platform. The relays
can be assigned to any of a number of discrete signals from any Analyzer module connected to the Platform.
The RS-232 or RS-485 outputs can support
either Modbus or AK, and can be used to
communicate to any Analyzer connected to
the Platform.
Menus controlling the operation of the local
I/O module can be found under Expert controls and setup…, Auxiliary module setup…,
Local I/O module…
NOTE
V2.2 Platform software supports
only the analog output and a limited
version of AK on the local I/O module. V2.3 Platform software supports
the features mentioned here.
Instead, tell the Platform that the Local I/O
module is installed, and then assign its outputs to the signals desired.
Installation
If the Local I/O Module is received as a separate unit, carefully examine the shipping carton and contents for signs of damage.
Immediately notify the shipping carrier if the
carton or contents is damaged. Retain the

THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES OF QUALITY WHETHER WRITTEN, ORAL, OR IMPLIED (INCLUDING ANY
WARRANTY OF MERCHANTABILITY OF FITNESS FOR PURPOSE).
The remedy(ies) provided above shall be purchaser's sole remedy(ies) for any failure of
Rosemount to comply with the warranty provisions, whether claims by the purchaser are based
in contract or in tort (including negligence).
Rosemount does not warrant equipment against normal deterioration due to environment. Factors
