Operational mode The WMS has the following operational modes:
Standby Mode
The WMS remains idle and does not perform any measurements.
Starting
The WMS starts the pumps but is not yet measuring
Sensing Mode / Operation
The WMS is measuring.
Verifying
The WMS remains idle and all pumps etc. are shut off – but the WMS is measuring

1.3. Product Description
The MES1003 operating principle is based on the standard MEPC.340(77) which in overall terms defines how to measure
the three required substances: PAH, Turbidity and pH.
The system consists of Washwater Analyzing Unit (WAU) and one of two Sample Units: WSU which offers a sample pump
and WSR which offers pressure reduction.
The WAU contains all components which control and perform the measurements. This includes the computer which
controls all operations in the system and the measurement chamber with the three sensors measuring PAH, Turbidity
and pH. The measured values will be recorded and reported to the user and is available through the display on the front
door and through the Modbus.
The WSU contain the de-bubbler, temperature sensor and relay for the sample pump. The temperature sensor is used to
report the temperature in the sampling point. The de-bubbler is a passive component which removes any bubbles in the
sample water as they interfere with the turbidity measurement. Turning the pump on/off is controlled by the computer
in the WAU. Two protection devices are built into to WSU in order to protect the pump and motor from breaking down in
case of lack of sample water and motor overload.
The WSR contain the de-bubbler, temperature senor and a pressure reduction valve. The temperature sensor is used to
report the temperature in the sampling point. The de-bubbler is a passive component which removes any bubbles in the
sample water as they interfere with the turbidity measurement. The pressure reduction valve reduces a high water
pressure at the input to a lower pressure at the output suitable for the WAU. The WSR also contains a safety function
which will lead water to the bilge in case of a pressure reduction valve fault.
The MES1003 interfaces to external systems through Modbus TCP/IP. A local display enables the user to perform setup
and control the system.

1.4. Functional Features
The Washwater Analyzing Unit (WAU) cabinet is equipped with a control panel with a relevant button layout for local
operation. The integrated control panel on the lid of the WAU gives the user access to information about the system and
the measured values for PAH, turbidity and pH.
Among available local control features and information are:
Visual Power ON indication.
Visual Warning indication.
Visual Alarm indication.
Control interface status of the systems operational modes.
Control interface notifications in case of an error or warning.
Menu for setting up the system.
1.5. Startup
Make sure that both the WAU and the SU are connected with the ship's power grid and that the breaker for WMS systems
power supply is ON.
Illustration 2: illustration of a Breaker for a WMS system
Applying power
When power is applied to the WMS system, the software starts booting. When the display is lit, the WMS is ready for
operation. The system start out in standby mode and the WMS starts measuring after having received a command to do
so.
The startup procedure works in the following way:
The screen is illuminated and an IXA animation starts:
All LEDs are turned on.
When the animation is finished, the LEDs turn off, except On LED and Status LED.
Warning LED will turn on if a warning is active.
Alarm LED will flash if an alarm is active.

1.6. First Time Setup
The WMS is initially configured with date and time at the time of its production, however during shipping the clock may
have drifted. To ensure correct operation and logging, the time must be set before it is taken into use. The WMS will
continuously broadcast an alarm until the time is adjusted.
When the WMS is powered on for the first time, it will automatically enter the time setup menu on the local control panel
from where the time can be set immediately. For manual setup of the time see 2.2.2 - Menu Display Examples.

2.3. Local Control
Local Control can be used when the system is inspected or calibrated by crew. When Local Control is enabled, the WMS
can only be started and stopped from the LCP. Local Control can be enabled using the Modbus interface or using the LCP
Local Control can only be disabled using the LCP. Local Control ensures that the sensor is not started unintentionally by
another system thus allowing crew to perform inspection and maintenance operation on the system.
When Local Control is disabled, the WMS must be started and stopped using command through the Modbus.
When Local Control is enabled, readings from the sensor can still be obtained over Modbus. The only difference is that
the system can’t be started over Modbus.
2.4. USB Interface
The USB interface, located in the WAU inside the controller box, can be used in combination with the local control panel
and a USB drive to update the sensor software, extract a diagnostics report or download a measurement log. The USB
interface also includes the possibility to save/restore setup. The placement of the USB port can be seen in Illustration 19;
it is located behind the cover of the control box in the WAU.
The USB stick must comply with the following:
Max 16 G
1 partition only
Formatted to FAT32

2.4.1. Diagnostics Report
The diagnostics report is an important tool to help service personnel analyze the WMS’s behavior. If a query regarding
the WMS’s performance is submitted as in 5.5 Alarms and Troubleshooting, a diagnostics report may be required to find
the source of technical issues.
Ensure the USB drive is working and is not full, before creating the diagnostics report.
To create a diagnostics report:
1. Insert a USB drive
2. Navigate to the maintenance menu
3. Select Diagnostics Report
Follow the instructions on the screen and proceed by pressing OK.
Illustration 21: Step 1 Illustration 22: Step 2
Illustration 23: Step 3 Illustration 24: Step 4
After successful completion, a directory named Diagnostics will be placed in the root folder of the USB drive.
If a USB device is not found, check or replace the USB drive, and start the sequence again by pressing OK.

2.4.2. Updating Software
The software package obtained from Danfoss IXA consists of a directory with several files used for updating the software
suite. The entire software directory must be placed on a USB drive before it is inserted into the WMS. Make sure that only
one software folder exists on the USB drive, to ensure the intended version will be installed.
Do not turn the WMS off after beginning a software update, the WMS will automatically reboot when finished.
To update software:
1. Insert the USB drive with the software suite in the WMS
2. Navigate to the Maintenance submenu on the LCP
3. Select Update Software.
Illustration 25: Maintenance submenu
Proceed through the guide by pressing OK, and if the directory is found, the software update will begin. The update can
take several minutes. Wait for the sensor to reboot, the LCP screen may freeze during the update.
Illustration 26: Step 1 Illustration 27: Step 2
Illustration 28: Step 3
If a USB device with a valid software package is not found, the update will not start, and an error message will be
displayed. Ensure that the complete directory is present on the device and try again. Press OK to restart the guide.
