1.3 About the System
The modular design of the CEMS makes it possible to monitor different gases according
to customer specifications. The G7000 can monitor the SO2 and CO2 concentrations in
exhaust gas according to the requirements in IMO regulations – NOx Technical Code 2008
and the requirements in MEPC.259(68). It provides an accurate measurement of SO2 in
ppm, CO2 in percent and the SO2/CO2 ratio, and presents these values on both the HMI
and Modbus TCP for logging and customer processing.
The system consists of a sampling and sample conditioning system and -up to two Multigas
Analyzers.
The unique double sample conditioning unit prepares the next sample simultaneous with
measuring from the current sample and hereby ensures a fast response time. This unique
feature allows the system to sample from up to 5 different sample points per system via
the multiplexing device.
Furthermore, the system uses an air conditioner to maintain an optimum working
temperature inside the monitoring unit. All materials are specially selected to resist the wet

Introduction

and acidic exhaust gas after a scrubber. The robust design is aimed for harsh marine
applications and long intervals between services.
The CEMS is designed for easy calibration and maintenance. The system is arranged with
automatic calibration by means of Internal Calibration Glasses together with instrument
air. The system can also be verified by test gases in order to show compliance. To avoid
damage, due to condensation it is recommended to run the system continuously.

3Safety Aspects
Before operating the system, please study this Operation Manual and the
Technical Drawings for each system in their entirety.
Warning
Follow the instructions.
Please ensure correct connection of all power, signal cables and air supply before
operating the CEMS.
The multiplexer, probes and sample lines will be hot during operation. Please pay
attention to the risk of burn.
Do not obstruct the circulation of supply/intake air by the air conditioner.
The system is only suitable for installation in a safe, non-hazardous area and is not
suitable for use with flammable or explosive media.
It should be pointed out that installation and operation of this system and associated
equipment must be carried out by skilled and trained personnel. Green Instruments A/S
does not take any responsibility for the operation of the equipment and associated
equipment whatsoever.
If the system is used in a manner not approved by Green Instruments A/S, the function
and protection provided by the equipment may be impaired.
Successful and safe operation of this equipment depends on proper handling,
installation, operation, and maintenance.
Hazardous voltage!
Disconnect the power before installing or servicing the equipment. Ignoring this warning
may result in severe personal injury or material damage. Read the instruction carefully to
ensure correct connection of all power and signal leads.
Make sure that the correct voltage is connected to the system.
Circuit breaker!
The installation must include a means of isolating electrical power by a clearly marked
switch or circuit breaker external to the system. The external switch or circuit breaker shall

Safety Aspects
12
be in close proximity to the system and within easy reach of the operator. The CEMS is
fitted with a safety switch, placed underneath the air condition unit, and this interrupts the
power to the downstream components.
Overload protection!
For compliance with the safety requirements IEC 61010-1 (2010), the installation must
include a means of overcurrent protection to provide protection against excessive energy
being drawn from the power supply system in case of a fault in the equipment.
Protective earth!
The system must be connected to protective earth.
Installation and fault finding!
Electrical installation and fault finding on the system should only be undertaken by a
suitably trained and qualified engineer.
EMC!
For compliance with the EMC product standard IEC 60533 (1999), the connection cables
for the main supply and communication signals should be shielded or provided with
equivalent protection.
Probes and heated sample lines!
To avoid risk of damage/electrical shock, the probes and heated sample lines must be
installed and completely connected before powering up. When the system is powered on,
the connections to the probes/sample lines must not be interrupted. The equipment must
not be exposed to strong mechanical stress.
Protect the heated sample lines against overheating, sharp edges, mechanical stress,
chemicals, dangling, both during the installation and when it is installed.
In case the heated sample lines must penetrate deck or bulkhead with special requirements
concerning water tightness or fire protection, the penetration has to be carried out
according to current rules.
Blockage of the gas sampling system!
Do not block the gas sampling pipes to or from the system when the system is in operation!
Damage of components can occur. Only during leakage test short periods intentional
blocking is allowed.
Leakage!
Components in the gas sampling lines may not be disconnected, except for troubleshooting
or repair, due to the risk of leaks. Escaping exhaust gas can cause damage to the equipment
and faulty measurements may occur. After reassembling any components in the gas
sampling lines, a leak test must be performed.

CEMS
Version 2.7 – Revision February 2021 13
Harmful components!
The exhaust gas is hot and may contain poisonous media that are potential harmful to
humans.
Before removing any component in the gas sampling system, make sure that the gas
channel is plugged to avoid exhaust gas escaping.
Condensate from gas driers may be aggressive and cause corrosion and chemical burns.
Protection must be worn whenever risk of being in contact with combustion gas and
condensate occur!
Recycling!
Please do not dispose the equipment with regular disposal. Disposal should be in
accordance with the requirements of the current statutory regulations.
Symbol identification!
Caution, risk of danger
Protective earth
Caution, risk of electrical shock
Caution, hot surface

4.1 Home
Home displays an overview of all current measurements. The current state of the system
and the probes can also be seen as status information on the probe and status buttons.
It is always possible to go back to Home from any page or sub-menu by pressing the Home
button on the right of the HMI screen.
Figure 4-2: Home
4.2 Probe 1 - 5
Probe 1…5 pages as shown in Figure 4-3 displays the current values and trend curves of
SO2, CO2 and SO2/CO2 ratio values of the selected probe. The values are shown for the
last 60 minutes.
Pressing Probe 1…5 on top of the HMI screen gives access to each probe’s screen. There
is an indication of probe status in each probe button:
OFF: the probe is not currently in use or is not mounted on the system
Measuring: the probe is in measurement mode (see Figure 4-3)
Heating: the probe is in warming up period (see Figure 4-4)

Menu Structure
16
Standby: the probe is currently heated up to operation temperature and in standby
mode, i.e. ready to sample.

4.3 Log
Note
This logging function cannot substitute the data recording and processing device
according to IMO regulations MEPC 259(68)

CEMS
Version 2.7 – Revision February 2021 17
Pressing Log gives access to the Log screen where measurement values for all configured
probes may be seen. See Figure 4-5
To access the log of SO2, CO2 or Ratio, press the relevant button in the lower
right corner of the Log screen.
The coloured arrow will indicate the live trend value.
Each probe has its own colour trend curve. The colour is indicated in the probe buttons on
top of the Log screen. Figure 4-5 shows that the blue trend curve is for probe 1(Eng-1),
green for probe 2(Eng-2), yellow for probe 3(DG-1), white for probe 4(DG-2) and red for
probe 5(Inc.).
Figure 4-5: SO2 Log Screen
The time scale of the trend curve is 24 hours. There is 1 sample value every 5 minutes.
The selected date is displayed on top of the graph. The period of the time is shown on the
bottom of the graph. The arrow up and down on the right side of the graph is to scale up
and down the log value axis.
There are 4 function buttons right below the trend curve for going back and forth in the
history trend. To go back to a certain date, please press the calendar button right below
Probe 1(Eng-1) button on the top left of the screen and choose the date.
It is possible to copy the measurement log and historic alarm data to a USB memory stick
which must be inserted in the HMI. After the USB memory stick is inserted in the HMI,
the data can be saved by pressing the “Log -> USB” button.
