2. Introduction
2.1 About the system
The G6200 water monitoring system is a modular system that continuously
monitors scrubber water. With its robust and durable design, the system
can be used in both open, closed, and hybrid systems and includes a de-
bubbler, which avoids interference due to sample degassing.
Compared to our G6100 version, the G6200 WMS is simpler, with no need
for a pump cabinet unit or a pressure reduction unit. The G6200 WMS only
requires water from scrubber pumps or a free-standing supply pump.
The G6200 WMS has a wide water pressure and ow range, making it
suitable for both the inlet and outlet of the scrubber. The ranges are highly
exible, meaning dierent pumps such as impeller pumps or hose pumps
can be connected to the system. Having a WMS on board is an extremely
eective way of ensuring compliance with international regulations. The
G6200 WMS is fully compliant with MEPC.259(68) & MEPC.340(77).
The system design and choice of materials used are based on more than
one thousand systems installed on various vessel types. The system is easy
to service, includes on-board verication and does not include a costly
sensor servicing program.
2.1.1 PAH
The polycyclic aromatic hydrocarbons module measures the content of
PAH in water as specied by MEPC.259(68) & MEPC. 340(77). The module
uses a UV technique and detects PAH concentration in μg/l (ppb) in water.
A special measuring arrangement ensures a reliable and repeatable
measurement while keeping the need for cleaning at an absolute minimum.
A unique feature is local validation which ensures a reliable measurement of
PAH.
The PAH measurement is compensated for the eects of turbidity by means
of a turbidity compensation formula and input from the turbidity sensor
module G6120.

Introduction
Page 9of 82
2.1. 2 Turbidity
The Turbidity measures the turbidity of water in accordance with
MEPC.259(68) & MEPC.340(77). The module used a 90° IR technique in
accordance with ISO 7027. The Turbidity module can detect soot, particles,
and suspended soil in the water. Special precaution is taken to avoid
interference from dissolved gasses and bubbles and an integrated wiper
keeps optical fouling at a minimum. Certied calibration solutions are used
to perform local calibration.
2.1.3 pH & Temperature
The pH/Temperature measures the pH value and temperature of the water.
Temperature compensation ensures accurate and reliable measurements.
Calibration is simple and fast.

2.3 Storage and handling
2.3.1 Storage
The ambient temperature must be 0-45°C, and the relative humidity must be
20-90% RH.
The pH/Temperature sensor uses an electrode which is stored inside the
system in a separate container to maximize electrode lifetime. The electrode
is packed in a sealed bag and delivered with a safety cap on to ensure the
electrode is kept moist. The electrode will be damaged if it dries out. Refer
to section 6.5 for additional information.
2.3.2 Calibration kit
Calibration solutions come with expiry dates. The calibration kit has an
expiry date of approximately 12 months from the date of delivery. Store
calibration kits at 5-25°C.
Calibration solutions can become damaged at temperatures below 0°C
and temperatures above 25°C may reduce their accuracy and lifetimes.
However, storage temperatures of up to 35°C for calibration liquids are
permitted during transport but only for a period of seven days.
When using the calibration liquids, ensure their temperature is about 20°C
for the highest accuracy.
2.4 Control of delivery
Please check the equipment upon arrival, ensuring that the equipment has
been transported properly.
Check for any damage. If any damage is found immediately make a note on
the delivery document. Remove the packing and check for intrusive water or
signs of humidity.
Check for missing parts against the packing list. Any discrepancy or damage
should be reported to Green Instruments A/S immediately.

3. Safety
Before operating the system,
read and understand the entire user manual.
WARNING
Failure to follow the instructions can lead to serious injury or death.
Follow the instructions:
■Ensure all power and signal cables connections are correct before
operating the water monitoring system.
■The PAH sensor module and turbidity sensor modules use UV and IR light
that can damage eyes. Do not look directly into the lenses.
■Avoid air in the sampling system to prevent the risk of air locks occurring,
which can trigger a ow alarm.
■Always ensure there is positive suction pressure and keep discharge
pressure as low as possible in order to maximize pump lifetime.
■Do not block a safety valve’s drain or outlet connection, as this will
damage components.
■Check the safety valve to ensure it functions correctly. Follow the planned
maintenance program.
■The system may only be installed in a safe, non-hazardous area. It must
not be used with ammable sample liquids. Non-wetted components such
as enclosures must be kept dry and clean.
WARNING
Use of unqualied, unskilled, and untrained personnel can lead to serious
injury or death.
The installation and operation of this system and associated equipment
must be carried out by skilled, and trained personnel. Green Instruments
A/S bears no responsibility for the operation of the system and associated
equipment. The correct and safe operation of this equipment depends on
proper handling, installation, operation, and maintenance.

Safety
Page 15 of 82
The equipment must only be used as described in this user manual. If the
system is used in any other way not specied by Green Instruments A/S,
equipment safety may become impaired. Green Instruments A/S cannot be
held liable for any resulting damage or injury.
Hazardous voltage
Disconnect power before installing or servicing the equipment. Failure
to disconnect power can result in severe personal injury or damage to
materials. Read the installation instructions carefully to ensure all power and
signal leads have been correctly connected
Ensure that the correct supply voltage is connected to the system.
Circuit breaker
The installation must include a means of isolating electrical power by a
clearly marked external switch or circuit breaker. The external switch or
circuit breaker must be in close proximity to the system and within easy
reach of the operator.
Overload protection
In accordance with the safety requirements in IEC 61010-1 (2010), the
installation must include a means of overcurrent protection to provide
protection against excessive energy being drawn from the system power
supply if the equipment has a fault.
Protective earth
The system must be connected to protective earth.
Installation and fault nding
Risk of electrocution
Electrical installation and system fault nding may only be carried out by a
suitably trained and qualied engineer.
EMC
In accordance with the EMC product standard IEC 60533 (1999),
connection cables for the main power supply and communication signals
must be shielded or have equivalent protection.

ATTENTION
Sensors can become damaged. The sensor modules must be connected to
the WMS before powering up otherwise they can become avoid damaged.
When the system is powered on, the connection to the sensor modules
must not be disconnected. If a sensor is to be connected or disconnected,
switch o the power rst. The equipment must not be exposed to strong
mechanical shocks.
ATTENTION
Pressurized system. Never shut-o the pipeline to or from the system when
the system is operating, as this may damage components.
De-pressurize the system before removing any wetted components.
WARNING
Harmful components: poisoning and chemical burns hazard.
The water can contain poisonous components that are potential
harmful to humans and animals. Some calibration solutions contain high
concentrations of harmful components. There is a risk of chemical burns.
Wear personal protective equipment whenever there is a risk of coming into
contact with the water or calibration liquids.
Recycling
Do not dispose of the equipment with normal waste. Disposal must be
carried out in accordance with the requirements of the applicable statutory
regulations.
