GAA610-M ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B 9

2 Design and function

Measuring principle

The GAA610-M is based on ABB’s proven NDIR (Non-Dispersive
Infrared) measurement technology.

The analyzer module Uras26 allows for reliable measuring and
monitoring of the limit values for SO

and CO2 and reports the

2

ratio as specified by the IMO (International Maritime
Organization), and it can be employed for continuous monitoring
of CO if required.

Therefore, additional devices, such as the sampling probe, the
sample gas line, the sample gas cooler, pumps and filters ensure
that the sample gas entry conditions of the connected gas
analyzer are met, and a proper measurement result is obtained
regardless of the process and the local conditions.

The sample handling system is specific for the applied
measuring principle.

The GAA610-M analyzer system is a complete turn-key solution

Device description

The GAA610-M is a multi-component analyzer system
continuously providing real-time data of relevant pollutants like
SO

/CO2 ratio.

It proves compliance of vessels to low emission limits of
emission control areas (ECA zones) and global limits.
The measurement can be used to control the exhaust gas
cleaning system on board, so called scrubber as well.

The GAA610-M is proven for use on board by all major
classification societies and complies with Marpol Annex IV
requirements and NO

Technical Code2008.

Reducing maintenance hassles during ship operation has been
the guiding principle for development. An increased uptime is
provided with the GAA610-M by its robust and simple design as
well as its innovative digital features allowing for tailored
services according your needs.

The GAA610-M analyzer system extracts the sample gas from the
exhaust gas stream.

The gas analyzer cannot process the sample without further
treatment as e.g. an excessive dust content, temperature and
dew point, excessive or insufficient pressure and interference
components in the sample gas can affect the operating ability of
the gas analyzer and distort the measurement result.

with the following components:

• Probe and filter unit for proper gas sampling

• Heated sample gas line for feeding the sample to the gas
analyzer

• Sample conditioning components like sample gas cooler,
filters and pump to ensure the gas conditions for reliable

Sample gas flow

The sample gas is extracted from the exhaust duct after the
scrubber by a heated sample probe.
The heated sample gas line is the connection and supplying line
between sample probe and analyzer cabinet. The probe and the
sample gas line are heated to avoid condensation.
To clean the filters in the sample probe a back-purging system
via the filter chamber can be integrated. The filters are cleaned
with pressurized air every 12 hours cyclically or automatically
when the flow is below the minimum value.

At the entrance of the analyzer cabinet there is a 3/2-way
solenoid valve. The gas flow goes to the gas cooler and via filter,
flow meter, pump and aqua stop filter to the gas analyzer.

(356 °F). The filter is equipped with a ceramic filter element.

To clean the filters in the sample probe a back purging system
via the filter can be integrated.

Heated sample gas line

The heated sample gas line is directly connected to the filter at
the probe. The core is a PTFE hose. The line is heated to 180 °C
(356 °F).

The temperature is controlled with a Pt100 resistance
thermometer and the power/temperature is adjusted with a
temperature controller installed in the cabinet. In case of a
deviation from the set value a message is generated and
displayed on the AO2020-Display.

Temperature controller

A Temperature controller is used to control the temperature of
the heated sample gas line.
An alarm signal is output as soon as the temperature drops
below the minimum temperature limit.

Solenoid valve

A solenoid valve is installed to switch between measuring gas
and ambient air during calibration and standby mode.

Aqua stop filter

The aqua stop filter is the final protection for the analyzer. The
aqua stop filter holds back any humidity.

AO2020-Uras26 gas analyzer

The AO2020-Uras26 gas analyzer is integrated into the analyzer
system for measuring CO
The main components are an infrared source (lamp), a sample
cell, a wavelength filter, and the infrared detector.
The sample gas is pumped into the sample cell, and the gas
concentration is measured electro-optically by its absorption of
a specific wavelength in the infrared wavelength range.

Sample Gas Cooler SCC-C

Temperature controller

Figure 3: Sample Gas Cooler SCC -C

The sample gas cooler defines the water content of the sample
at a certain dew point (typically 3 °C). Therefore, the temperature
of the sample falls from approx. 180 °C to the set point of the
sample gas cooler and condensation will occur. The condensate
is removed with a hose pump and collected in a separate bottle.

The sample gas cooler is controlled by the system and the
following signals can be output:

• Condensate level:
The level of the condensate collecting bottle is monitored
and a signal will output (displayed via a red lamp on the
front panel) when maintenance / emptying the bottle is
required.

• Fault cooler:
A status signal "fault cooler" is set if the cooler
temperature is too high. The signal is also provided as
"Failure" status signal.

• Failure alarm:
If a failure of the cooler is detected, the feed pump is
switched off and the system is set to system failure
mode. The system failure mode is displayed on the panel
and provided as a status signal.

Procedures for laying the sample gas line

Wall break-through

Laying in ducts or shafts

Figure 15: Laying in ducts or shafts

A Do not lay the heated sample gas lines directly side-by-side

in an enclosed duct or shaft. This results in heat
accumulation.

B Ensure that the hoses do not touch. Maintain a distance of

25 mm. Provide adequate ventilation. Heat can be conducted
away as a result.

Soiling the heated sample gas line

Figure 18: Wall break-through

A Do not lay the heated sample gas line in a wall break-through

which is subsequently sealed with a sealing compound under
any circumstances. The sample gas line will be destroyed by
overheating in this case!

B When laying the heated sample gas line through a wall break-

through, use bulkhead plates with conduit thread cable
glands, in order to provide adequate cooling of the sample
gas line.

Laying several heated sample gas lines

Figure 16: Soiling

A Prevent powdery substances, adhesives or other thermally

insulating materials from soiling the heated sample gas line.
Otherwise, over\-heating will occur at these points.

B If soiling occurs, clean the materials and remedy the cause.

Heat can be conducted away again as a result.

Wrapping the heated sample gas line

Figure 17: Wrapping

A Avoid heat accumulation through wrapping the heated

sample gas line with other materials, otherwise the sample
gas line will overheat at these points. Do not cover the area
near the temperature sensor, otherwise the rest of the
sample gas line will cool down.

B Do not wrap the sample gas line. Ensure that the area near

the temperature sensor is exposed.
This results in error-free temperature measurement.

Figure 19: Bundling several gas lines

A Avoid bundling or laying several heated sample gas lines, so

that they touch each other. This results in overheating at the
contact points.

B Lay several heated sample gas lines separately with a

distance of at least 2.5 cm and provide adequate ventilation.
Heat can be conducted away as a result.

9 Gas sampling with automatic back-purging

General

Filter plugging

During operation of the analyzer system the dust which is
contained in the sample gas will accumulate in the probe filter of
the gas sampling system. This is uncritical if dust concentration
is low and only requires a cleaning of the filter periodically in
longer time intervals.

But if the dust concentration is high, the dust accumulation in
the filter will cause an increasing pressure loss, and the gas feed
of the sample gas pump decreases and also the sample gas flow,
and finally the filter is blocked in an extreme case.

Pump suction increase

At first this effect can be compensated by occasional
adjustment of the sample gas flow, which increases the suction
of the sample gas pump.

Components for back-purging

To carry out the automatic back-purging of the filter unit,
components are integrated in the analyzer system as follows:

• The back-purging air panel with 6 bar pressure reduction
valve, pressure regulator and 2 l buffer tank for effective
pressure pulses also with lower airflow rate

• Two solenoid valves (SOV1, SOV2)

• The gas sample probe with filter unit

• The GAA610-M control program.

Control of the back-purging procedure

The back-purging procedure is integrated into the GAA610-M
control program of the analyzer system.

The manual handling is carried out with the pushbutton ‘Back­Flush’ on the analyzer system’s front plate.

The pump is strong enough, but if the fouling continues, the
needed suction for keeping up the required gas flow will increase
to such a high value, that several unfavorable effects will emerge
and can finally be accepted no longer.

Filter cleaning

If the suction exceeds a limit of about 300 mbar (accordingly the
absolute pressure falls below 700 mbar), the sampling system
filter has to be cleaned.

The filter units can be cleaned automatically by a back-purging
procedure with compressed air. This procedure is controlled by
the GAA610-M.

Start of the back-purging procedure

The start of the back-purging procedure can be carried out:

• Controlled by time

• Controlled by event. If the sample gas flow is too low, a
back-purge cycle is automatically started.

• Manually controlled.

Start controlled by time

After a cycle time has run down, the back-purging procedure will
start automatically. A cycle time of 12 hours is factory-set.

Start controlled by event

A flow fault during normal measuring operation will start the
automatic back-purging procedure.

After back-purging was started by event, the procedure will run
only once.
If the procedure is finished (waiting time 30 s) and the starting
event (flow fault) is still active, the back-purging procedure will
not start again, even not controlled by time, and a status
message will be generated. However, the back-purging
procedure can be started manually after 30 minutes.

Manually controlled start

The manual start of back-purging procedure can be executed
locally by pushing the ‘Back-Flush’ pushbutton on the analyzer
system’s front plate.

Switch over

At first the sample gas valve −Y60 is switched over to position
‘Calibrate zero / Ambient Air’. This separates the sample gas
conditioning system and the analyzer system from the sampling
system and protects it against the back-purging pressure.

At the same time the status ‘Maintenance mode’ is activated and
all analog outputs and limits are set on hold.

• The display reports ‘Probe purging’.

• The Modbus signal ‘Sample line1 in purging’ is set to ‘1’.

• The Modbus signal ‘Line 1 in operation’ is set to ‘0’.

• The lamp ‘Line1 Measuring Status’ is off.

Back-purging probe filter

The back-purging procedure continues with the back-purging of
the probe filter. To increase the cleaning effect, the compressed
air is applied not continuously but by two 2 s pressure impulses
alternating with a 2 s interval each.

Back-purging probe tube

After this the probe tube is purged back in the same way with
two pressure impulses. A single pressure impulse of 4 s is
followed, to blow out the remaining dust from the tube.

Post-purging period

The calibration valve switch back to position ‘Measure’ will not
finish the back-purging procedure, because first the actual
sample gas must flow through the pneumatic system to purge it,
and the analyzer must adjust to the new actual measuring value.
A purge time of 90 s is factory-set.

End of the back-purging procedure

The back-purging procedure is not finished until the purge time
has expired. Now the analog outputs and limits are set free
again and they will take over the actual values. The message
‘Purge back active’ in the display as well as the status signal
‘Maintenance mode’ will vanish.

Cycle time

Cycle time duration

The cycle time is given as the time interval between two
automatic starts of the back-purging procedure. The higher the
dust concentration in the sample gas and the higher the sample
gas flow, the shorter this time interval must be set, to avoid a
blocking of the gas sampling probe filter.

Cycle time factory setting

The parameter ‘Cycle time’ is factory-set to 12 h.

Optimum cycle time setting

The cycle time should not be adjusted shorter than needed,
because during the back-purging procedure (approx.18 s) and
especially during the post-purge time (factory-set to 90 s) no
measurement can be made. The optimum time will have to be
found out by operational experience.

Cycle time minimum value

The cycle time should not be below a lower limit.
The back-purging procedure with cold compressed air causes a
cooling of the heated probe filter, and the filter temperature
regulation needs some time to correct this temperature
decrease.
As the filter heating regulation is a rather slow control loop, this
time will be relatively long. Therefore, the cycle time should not
fall below approx. 60 min.

Event-controlled start of the back-purging procedure by filter plugging

Should despite the time controlled back-purging a probe filter
blocking occur caused by temporary larger amounts of dust,
with the result of a sample gas flow decrease beneath the
admissible limit, an additional back-purging procedure is started
as a result, and the probe filter is purged free in between.

Adjustment of the cycle time

To adjust the cycle time the parameters of the AO2020 program
must be changed. Please contact ABB service.

Post-purge time

Post-purge time duration

The post-purge time at the end of the back-purging procedure
must be such, that the complete pneumatic system is flushed
with the actual sample gas and the analyzer gets time to take
over the actual measuring value again.

The needed post-purge time depends on the respective layout of
the system (i.e. the length of the sample gas line) and will have
to be adjusted individually. A post-purge time of 90 s is factory­set.

Guide for the post-purge time

A guide for the needed post-purge time is given in the table
below. Please add the times for the pneumatic system, the
analyzer and the sample gas line.

m

Example

For an analyzer system with filter unit and 15 m sample gas line
at 60 l/h sample gas flow the post-purge time is calculated as
follows:

Post-purge time = 27 s + 20 s + 1.5 x 5 s + 45 s = 99.5 s

Adjustment of the post-purge time

To adjust the post-purge time the parameters of the AO2020
must be changed. Please contact ABB service.

… 10 Commissioning and operation

Analyzer cabinet air conditioner

Damage to the air conditioner

Damage to the air conditioner due to incorrect
commissioning.

• Do not attempt to operate the air conditioner while it is
horizontal or on its side, back or front. The refrigeration
compressor is filled with lubricating oil. This will cause
permanent damage to the air conditioner and also voids

If the air conditioner has been in a horizontal position, be certain
it is placed in an upright, vertical or mounting position for a
minimum of 5 minutes before operating.

Overload protection

The compressor is provided with automatic reset thermal
overload protection. This thermo-switch is located and mounted
inside the plastic enclosure clipped to the compressor.
The switch operates when the compressor overheats due to
clogged or dirty inlet air filter or if ambient air temperatures
exceed nameplate rating or if enclosure dissipated heat loads
exceed the rated capacity of the air conditioner.

The thermal overload switch will actuate and stop compressor
operation. The blowers will continue to operate, and the
compressor will restart after it has cooled to within the thermal
overload cut-in temperature setting.

Principles of operation

If electrical power to the air conditioner is interrupted and
reapplied immediately, (within 3 to 5 seconds), the compressor
may not restart due to the high back pressure of the
compressor. It takes a minimum of one (1) minute after
shutdown for the compressor suction and discharge pressures
to equalize in order for the air conditioner to restart.
Operating the air conditioner below the minimum ambient
temperature or above the maximum ambient temperatures
indicated on the nameplate voids all warranties.

The moisture that the enclosure air can contain is limited. If
moisture flows from the drain tube continuously this can only
mean that ambient air is entering the enclosure. Be aware that
frequent opening of the enclosure’s door admits humid air,
which the air conditioner must then dehumidify.

Start-up

Prior to start-up

Check analyzer system seal integrity.

Power supply activation

1. Make sure that all fuse switches are deactivated.

2. Turn on the analyzer system power supply with the main
switch.

3. Activate the fuse switches of the individual modules one
after the other.

Function check

The following events will occur after the power supply is turned
on:

1. The three ‘Power’, ‘Maint’ and ‘Error’ LEDs light up.

2. The different booting phases are displayed on the screen.
Also, the software version is displayed.

3. After a brief time, the screen switches to measurement
mode.

4. The STATUS MESSAGE softkey appears on the screen. This

Date and time check

A correct date and time setting are required for a proper
operation of functions such as automatic calibration and time /
date logging of error messages.

1. Select the date / time menu item:
‘MENU / Configure / System / Date / Time’

2. Check and, if necessary, correct the date and time according
to time on board.

3. The analyzer system is factory-set to the GMT+1 time zone.

GAA610-M ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B 45

Warm-up phase

The warm-up time for the system is approx. 2 to 4 hours.

The warm-up phase can take longer if the analyzer system was
not brought to room temperature before the power supply was
activated.

Note

During the warm-up phase measurement values can be outside
the ranges specified in the data sheet.

End of the warm-up phase

The warm-up phase is over when the temperature and flow
status messages are gone and the measured value drift is
acceptable. The latter depends on the size of the measurement
range.

Readiness, sample gas supply

At the end of the warm-up phase the analyzer system is ready for
operation and automatically activates the sample gas supply.

Calibration

Calibration should only be started after the warm-up phase.

11 Operation

General

The AO2000 series gas analyzers have several user interfaces:

• The local operation user interface is the display and
control unit on the gas analyzer (‘local HMI’).

• The remote operation user interface is a PC running the
‘AO-HMI’ software (‘remote HMI’). For detailed
information on remote operation, see the ‘AO-HMI’
technical bulletin.

Note

The user interface is designated using the acronym ‘HMI’, which
stands for ‘human machine interface’.

HMI priority

A gas analyzer (or more accurately an analyzer module) can only
be operated via one HMI.

The password hierarchy controls which HMI has or retains
priority for operation (refer to the following table).

As a rule, the HMI with the level n+1 password has priority over
an HMI with the level n password. An exception is the local HMI
with level n password which has priority over a remote HMI with
a level n password.

Specifics for manual calibration

Manual calibration runs at level 0, thus no password is needed.

It is protected in the following manner from being stopped by
another HMI.

On entering the Calibrate menu the level 1 password is
automatically assigned.
Therefore, any other HMI must at least enter a level 2 password
in order to assume priority for operation. In this event the
calibration run would be stopped.

Access lock

Independent of the user interface priority adjustment it is
possible to completely lock the access to the operation of the
gas analyzer from a certain user interface (HMI).

This lock is effected by configuration of the function block
‘Access lock’.
The Technical Information ‘Function Blocks – Descriptions and
configuration’ contains complete information on the individual
function blocks.

Access denied

When a user tries to operate the gas analyzer via a locked HMI,
the following text is displayed after pressing the ‘MENU’ key:

Note

ACCESS DENIED !
The operation of the analyzer unit is not
permitted at this time.

If a second user with an HMI receives priority over another HMI,
all first user input not confirmed with the ‘ENTER’ key is lost and
processes in progress (e.g. calibration) will be stopped.

Access lock via password protection

As an alternative to the above-described complete access lock it
is possible to inhibit entering the main menu and thus switching
to the menu mode via password protection, see Password
protection on page 53.

Password protection

Password protection consists of three elements:

• Password level,

• User group and

• Password.

Password Level

Each menu item is assigned a password level. Password levels
are numbered with 0, 1, 2 and 3.

Menu items are assigned to different password levels in order to
assure that specific menu items can only be changed by
authorized users.

User Group

The definition of a user group is that every user that belongs to
it has access entitlement at certain password levels, i.e. can
make changes to the menu items at these levels.
Some user groups are set-up at the factory.
A user group can be made up of one or more users.

Password

Damage to the configuration of the gas analyzer.

After entering the password for password level 3, you can
access all of the function block applications!

• Make sure that changes in password level 3 are only made

Note

The ‘Function Blocks – Descriptions and Configuration’ Technical
Information contains complete information on the ‘Function
Block’ concept as well as detailed descriptions of the individual
function blocks.

Every user group set-up in the system has a password. The
password consists of six digits which can be entered via the
numeric keypad.

about five minutes (‘time-out’),

• or the user presses the ‘MEAS’ key twice in a row.

If the user presses the ‘MEAS’ key only once to switch back to

Viewing Menu Items

All users can view all menu items, regardless of password level,
without entering a password.

Changing Menu Items

All users can make changes to password level 0 menu items
without entering a password.
Password level 1, 2 and 3 menu items can only be changed if the
user belongs to the group authorized for that level and after the
user's password has been entered.

Note

Entering the main menu and thus switching to the menu mode
can be password protected, refer to Access lock on page 46.

Change Privilege

After entering the password the user is authorized to change any

measuring mode, the change privilege initially remains in place.
This is signaled by the flashing ‘Password active’ message
display.

In this way, the user does not need to enter the password again
before changing the menu items when switching back to menu
mode within the following approx. five minutes.

Note

The change privilege therefore refers to the time-limited
authorization to make changes to the menu items.
By contrast, the access right designates the principle

Note

For a detailed description of the individual parameters and menus, please refer to the chapter ‘Configuration’ in the operating
instruction OI/AO2000.

For reasons of brevity only the top-level parameters and functions are shown; the menu branches more extensively at most menu
items, e.g. into the various measurement components or into the selection and adjustment of values.

Password levels

For each menu item its password level (0, 1, 2, 3) is shown in the table.
For some menu items, individual sub-menu items are on a higher password level. These apply especially to those sub-menu items
which allow access to function block applications.

Note

The ‘Change password’ menu item is not assigned to a specific password level. In order to change a password the old password of
this password level must be entered.

Application

Dynamic QR Code is a unique feature for displaying dynamically
generated QR codes on the gas analyzer display.
The QR code displayed contains static system information as
well as dynamically generated information regarding system
configuration and the status of the gas analyzer.

Static data for the identification of the device includes, for
example:

• Manufacturing number

• Production date

• Software version

• Serial numbers of the analyzer modules and assemblies

that have been installed

Dynamic data for diagnostic purposes in the case of a fault
include, for example:

• Status Messages

• Measured values

• Temperature, pressure and flow-rate values

• Drift values

• Analyzer-specific values

In combination with mobile devices (smartphone, tablet, etc.),
Dynamic QR Code represents an innovative communication path
for the user, enabling improved, case-specific assistance from
the ABB service team.

This helps to shorten response times in the event of a fault,
thereby increasing the availability of your gas analyzers.

Dynamic QR Code is compatible with both the ABB app “my
Installed Base” and standard QR Code scanner apps

Handling

The QR code is accessed in the Diagnostic Menu of the gas
analyzer and indicated on the display.

The QR Code Scanner App installed in the mobile device scans
the QR Code that is displayed. The text information that is then
displayed on the mobile device is sent to the local service
contact specified in the “Measurement Care” contract, by email
or other means of transmission.

Alternatively, it is possible to take a photograph of the displayed
QR code and send the photograph to the service contact.

Calibrating the analyzer system

Impairment of the analyzer function

Impairment of the analyzer function due to improper
calibration.

• Only persons familiar with the calibration of comparable
analyzer systems are certified as being capable of such

Note

Calibration of the analyzer system has to be performed on board
every 6 to 12 months with test gas, in accordance to agreement
with respective certification class.

Conversion of concentration values

Care has to be taken, that the certified test gas used has to be
specified in % by volume. In case it is specified in volume by mole
there has to be a conversion as following:

XC mole fraction

XT mole fraction of the component in the reference state

Basics

The purpose of the calibration (adjustment) is to scale the
analyzer with a reference normal. This reference normal can be a
(certified) test gas or a built-in internal gas filled cell.

When calibrating SO
characteristics have to be considered. Firstly, SO
soluble gas, which means that parts of the gas may be solved in
water. On the other hand, SO
the infrared range. Therefore, it is important that the water
content in the measured gas is constant. This is achieved by the
gas cooler, which stabilizes the output to a constant dew point
of 3 °C below the entrance dew point. The error caused by the
overlay of the constant water signal is compensated in the
analyzer by shifting the zero point.

In continuous operation you will also get a lossless operation, as
long as the gas concentration and the inlet humidity do not vary
significantly.

Calibration – Principles

Preconditions

• Ambient air temperature: 5 °C to 40 °C

• If used, the flow from test gas bottle has to be as similar to
the flow via the membrane pump as possible. The flow of the
test gas bottle can be regulated via the pressure valve on top
of the bottle.

• Calibration should only be started after the warm-up phase
(Approx. 2.5 h)

Calibration control

The analyzer has two methods to control the calibration:

• Automatic calibration, see see page 75.

• Manual calibration, see see page 76.

In the following these are explained step by step.

Plausibility check during the calibration

If during calibration the gas analyzer finds implausible values
(e.g. if the span and zero values are equal), calibration is stopped
and an error message is generated. The values stored for the last
calibration remain in effect.

Output response and waiting period

If the Output Current Response parameter is set to Hold, current
output is halted for a specific time to allow the measurement
value to stabilize after automatic calibration is ended. By default,
this value is not hold.

The complete automatic zero-point calibration with ambient air
takes approx. 15 minutes and zero-point calibration with
ambient air and end-point calibration with calibration cells
approx. 25 minutes (Automatic calibration).

Test gases for zero calibration (without calibration cells)

A zero gas is required for zero calibration in any case. We
recommend using N

Test gases for end-point calibration without calibration

A test gas is required for each detector for span calibration
without calibration cells. In the case of automatic and externally
controlled calibration, a test gas mixture is required for all
detectors since all are calibrated simultaneously. The span gas
concentration should be 80 to 100 % of the end value of the
largest measurement range.
No test gas is required for the automatic calibration.

Automatic calibration

Definition

Automatic calibration means:
Calibration with internal gas filled cells and ambient air. Zero and
span calibration run automatically after starting. No test gas is
required for the normal automatic calibration. During automatic
calibration, the system runs on ambient air.

Starting automatic calibration

Automatic calibration can be started in two ways:

• At time intervals determined by the internal clock

• Manually via the display and operation unit of the gas
analyzer

In the following the start is described in detail.

Internal start

Automatic calibration is normally started cyclically on a time­controlled basis by the internal clock of the gas analyzer.
The cycle time and the start time of the automatic calibration
can be adjusted in the menu ‘MENU / Configure / Calibration
Data / Automatic Calibration’ (Password: 081500).

By default, a zero and endpoint calibration is performed daily at
7:00 am.

Manual start

When you reach the control page, you can start the calibration by
pressing key 6. You can also deactivate the automatic calibration
here. If this option is activated, the automatic calibration is no
longer performed.

You can also start the automatic calibration from the menu
‘MENU / Calibrate / Automatic Calibration / Zero & span cal.’

It is also recommended to perform the zero & end point
calibration here.

Message display

The automatic calibration can be manually started on the display
and control unit. The easiest way to start the automatic
calibration manually in the GAA610-M is from the control page.
You can find them in the overview by changing the pages with
‘>>’.

During automatic calibration an ‘Autocal Running’ message
blinks in the softkey line.

The calibration is completed. This can be checked in the logbook
‘MENU → Diagnostic/Information → Logbook’. The logbook
saves the last 500 events.

Manual calibration

Definition

Manual calibration means:
Calibration with test gases. Zero and span are calibrated
separately by pressing the gas analyzer display and control unit
softkeys.
Test gases are dry gases, without any amount of water content.
The resulting zero-point shift switches the complete sensitivity
line parallel and adjusts the calibration to the operating
conditions.

Note

Before calibration let the system run with ambient air for at least
12 min.

Starting manual calibration

In the following, the calibration with test gas is explained by
using SO

For the end point, the procedure is very similar. First select the
component and the option ‘Span gas’.
Now enter the concentration of the test gas you are using.
Please note that the test gas should have a concentration of
80 to 100 % of the measuring range. When you have confirmed
the concentration, you can give up the test gas using the test
gas connection.

From the first visible signal change wait at least 10 minutes
(Please do not purge the system with dry gas for more than
15 min.). After that, confirm your reading when the end point is
reached.

The system now performs the calibration for the span point.

Basic calibration

What does the basic calibration do?

A basic calibration of an analyzer module sets the module back in
an initial state. The offset drift and amplification drift are set to
zero. The drift history is lost. This should only be done by staff
who are aware of this function.

When should a basic calibration be performed?

Basic calibration of an analyzer module should be performed
only in exceptional cases when changes that affect calibration
have been made. This may be the case e.g. after exchanging
subassemblies. For the Uras26 analyzer module, a basic
calibration can be performed at the zero point for calibration to
the cooler dew point during commissioning at the sampling
point.

Check prior to a basic calibration

Prior to a basic calibration, check and ensure:

• That the gas analyzer is in proper operating condition

• That the sample conditioning units are in proper
operating condition

• That the correct test gases are being used.

• Before performing the basic calibration, the pressure
sensor should be calibrated.

Test gases

The zero and/or span calibration test gases are required for a
basic calibration.

Starting and performing the basic calibration

The basic calibration is performed for each sample component.
It is recommended to perform the basic calibration in zero and
endpoint.

If a new basic calibration is performed, it is recommended to
perform a pressure sensor calibration and a calibration reset
first.

Pressure Sensor Calibration

The pressure sensor calibration can be performed at ‘MENU /
Maintenance/Test / Analyzer spec. adjustm. / Atm. press. anlz’.

1. Confirm the module ‘URAS26’ and close the next message
with ‘BACK’.

2. Then enter the current atmospheric pressure and the
password. (Password: 081500)

3. After this, the sensor will be recalibrated. After the adjust all
gas components have to be gas calibrated.

Calibration Reset

The calibration reset can be performed at ‘MENU /
Maintenance/Test / Analyzer spec. adjustm. / Calibration Reset’.

This deletes the current data of the basic calibration.
Select the component and perform the reset. After that the basic
calibration can be performed.

Basic calibration

The basic calibration can be started in the menu ‘MENU /
Maintenance/Test / Analyzer spec. adjustm. / Basic Calibration’
(Password: 081500).

1. After entering the password, select the component and

the ‘Zero/span basic cal.’

2. Confirm your test gas concentration and wait until the

reading is stable as shown in Figure 39. The procedure for
the end point is the same.

3. After the basic calibration, you have to continue with

‘Measurement of calibration cells’.

Measurement of calibration cells with test gas

Definition

The measurement of a calibration cell in the Uras26 analyzer
modules means:

Determining what calibration cell ‘deflection‘ is equivalent to
the calibration reading with test gas. The ‘deflection‘ is
stored as the ‘set point‘ of the calibration cell.

When should calibration cells be measured?

We recommend measuring the calibration cells once a year. We
recommend measuring the calibration cells:

• after end-point calibration of a sample component with
test gas or

• after any change in measurement range limits or

• after a Basic calibration.

Starting and performing the Measurement of calibration
cells

Checking the seal integrity

When is the seal integrity check needed?

Complete seal integrity check of the analyzer system is reserved
for certified service personnel.
It should be carried out regularly at least every 12 months.
It must be performed after gas paths within the analyzer system
have been opened and following a restart from cold.
The seal integrity check should be performed according to the
pressure-drop method using a U-tube manometer.

Procedure

1. Interrupt the sample gas supply.

2. Close the sample gas outlet.

3. Disconnect the sample gas line from the sample gas inlet and
connect a tee fitted with a shut-off valve.

4. Connect the U-tube manometer half filled with water to the
free end of the tee.

5. Blow air or nitrogen through the shut-off valve to a gauge
pressure of approx. 100 hPa (= 1000 mm water column).

6. Close the shut-off valve. The pressure should not chance
measurably in 1 minute (pressure drop ≤ 1 hPa). A sharp
pressure drop is a sign of a leak.

Figure 40: CO2 end point with calibration cell

Please note that before measuring the calibration cuvettes, the
zero and end points of the respective sample components must
be calibrated with test gases.
During the measurement, the system should use ambient air.

1. Open the menu ‘MENU / Maintenance/Test / Analyzer spec.
adjustm. / Measure cal. cell’.

2. Please wait until the measured value is stable (Figure 40).

3. If this is the case, confirm the setting with ‘ENTER’.

measures for disposal.

Analyzer air conditioner

Compressor

The compressor requires no maintenance. It is hermetically
sealed, properly lubricated at the factory and should provide
years of satisfactory operating service.
Should the refrigerant charge be lost, recharging ports (access
fittings) on the suction and discharge sides of the compressor
are provided for recharging and/or checking suction and
discharge pressures.
Under no circumstances should the access fitting covers be
loosened, removed or tampered with.
Breaking of seals on compressor access fittings during warranty
period will void warranty on hermetic system.
Recharging ports are provided for the ease and convenience of
reputable refrigeration repair service personnel for recharging
the air conditioner.

Inlet air filter

Proper maintenance of the inlet air filter, located behind the
front cover, will assure normal operation of the air conditioner. If
filter maintenance is delayed or ignored, the maximum ambient
temperatures under which the unit is designed to operate will be
decreased.

If the compressor’s operating temperature increases above
designed conditions due to a dirty or clogged filter (or plugged
condenser coil), the air conditioner’s compressor will stop
operating due to actuation of the thermal overload cut-out
switch located on the compressor housing. As soon as the
compressor temperature has dropped to within the switch’s cut­in setting, the compressor will restart automatically. However,
the above condition will continue to take place until the filter or
coil has been cleaned. It is recommended that power to the air
conditioner be interrupted intentionally when abnormally high
compressor operating temperature causes automatic shut­down of the unit. The above described shutdown is symptomatic
of a clogged or dirty filter, thus causing a reduction in cooling air
flow across the surface of the compressor and condenser coil.

Note

• Do not run the air conditioner for extended periods of time
with the filter removed. Particles of dust, lint, etc., can plug
the fins of the condenser coil which will give the same
reaction as a plugged filter. The condenser coil is not visible
through the filter opening, so protect it with a filter.

• Continued operation under the above conditions can and will
damage and shorten compressor life. The air conditioner is
available with an easily removable inlet filter to facilitate
necessary cleaning. There should be no reason to neglect this
necessary maintenance.

Cleaning and changing the inlet air filter

Aluminum washable air filters are designed to provide excellent
filtering efficiency with a high dust holding capacity and a
minimum amount of resistance to air flow. Because they are
constructed entirely of aluminum, they are lightweight and easy
to service. To achieve maximum performance from your air
handling equipment, air filters should be cleaned on a regular
basis.

Filter removal and installation:

The inlet air filter is located behind the front access cover.

1. To access the filter, loosen the access-cover screw.

2. Swing top edge of access cover forward.

3. Slide air filter up and out of retaining tabs.
– The filter may now be cleaned, or new filter installed.

Cleaning Instructions:

1. Flush the filter with warm water from the exhaust side to
the intake side. DO NOT USE CAUSTICS.

2. After flushing, allow filter to drain. Placing it with a corner
down will assure complete drainage.

3. Recoat the filters with RP Super Filter Coat adhesive.
When spraying filter do so from both sides for maximum
concentration of adhesive.

Note

It is recommended to exchange the filter once a year depending
on the environmental conditions!
