2 Packing, Storage

2.1 Transportation and Packing The SDMEU comes packed in a cardboard box.

Unpack the unit and check it for damage in transit. Report any damage to the forwarding agent immediately.immediately

2.2 Storage Make sure to store the SDMEU in a clean, dry place, in the original packing, if possible. Do not remove the packing until you are ready to install the unit.

3 Scope of Delivery SDMEU comes packed and factory-assembled. Before commissioning the SDMEU, check the content of the package to make sure everything is present.

The following items are supplied:

Qty. Designation

1 pc. SensorDisplayMemoryEthernet Unit

1 pc. Voltage cable for the SDMEU, L=5m, (ZBE 08-05)

4 pc. Wall fixing tabs for mounting the housing

1 pc. SDMEU Operating and Maintenance Instructions (this document)



4 Description: The Sensor Display Memory Ethernet Unit SDMEU is a small control unit for saving measured values on an MMC memory card.

The following fluid sensors can be connected directly:

• ContaminationSensor CS 1000

• AquaSensor AS 1000

• HYDACLab

The display shows the fluctuating measured values of the connected sensors.

The measured values are saved as *.csv files every 60 seconds (a 128 MB memory card records ca. 3 years' worth of data).

For further processing and evaluation, the data can simply be transferred to Office applications, e.g. MS Excel.

Uses for the SDMEU include:

• Storage of data from fluid monitoring in the field.

• Test installation to validate sensors

Advantages offered by the SDMEU unit:

• Cost-effective, easy-to-install solution

• Simple processing and evaluation with MS Excel

• Ethernet / TCP/IP interface for open communication and OPC servers

• Program restarts independently after a voltage loss



5 Installation The SDMEU comes packed with 4 wall fixing tabs. These are used to install the housing on a flat surface, such as a wall or switch cabinet..



6 Connection The SDMEU comes packed with a l=5m voltage cable. Attach this cable according to the following figure.

The sensor connections are clearly defined, so the sensors must be connected to the SDMEU according to the following figure.

7 Control unit The core of the SDMEU is the easyControl unit from the Moeller company. It is composed of the following parts:

- easyControl control unit EC4P-222-MTAD1

- Memory module for MMC cards EU4A-MEM-CARD1

- Memory card RS-MMC 128 MB industrial

The control unit includes a 4-line text display with 16 figures per line, and has a real-time clock that will continue to record for at least 72 hours after a voltage loss.

The following are used by the INLETS/OUTLETS and interfaces of the control unit:

- Analog INPUT

• 1x CS1000 (cleanliness class)

• 1x HLB (changes in condition)

• 2x AS1000 – (1x temperature / 1x saturation)

- Ethernet interface (RJ45) provides access to the OPC server. The cover plate of the SDMEU must be removed during use.

For security reasons, the project and parameters relevant to the control unit are also saved on the memory card. Additionally, the memory card serves as a memory device for the data logger function.

8 Installation In the availability status, the project is located on the control unit. The application starts automatically when the power supply is switched on.

During the initial installation or in the case of a longer service life without power, the system clock should be checked and reset if necessary.

The system clock is checked when the program starts. If this times out, the following message appears on the display: „SET CLOCK -> Reboot system.” To set the system clock, first press the ESC to switch to the main menu. Set the hour and date by pressing the ALT button several times (see Setting the system clock, chapter 10.9).

The installation phase lasts ca. 105 seconds and appears on the start page as a % specification.

The sensors are connected to the M12-unit plug on the underside of the SDMEU.

To connect a CS 1000 to the SDMEU, you must first set the analog OUTPUT signal to HDA.ISO.

For all sensors, the SDMEU requires a 4-20mA signal for analog INPUT (no CS 1000 with a voltage signal!).

When using the SDMEU as a data logger, the memory card must be correctly inserted. This will show up on the display as "MC." To check this when the program is running, press the "ESC" button to switch to the main menu.

12.6 Changeover display mode automatic /manual

While the program is running, you can switch between the manual and automatic display of pages by pressing the "OK" button.

During the changeover, the set mode appears briefly on the display.

In automatic mode, the individual windows are displayed for 5 seconds. The sensor menus are skipped when a sensor and measured values are no longer present.

If the SDMEU finds no sensor, or if no sensor has been attached, this message will appear on the display.



13 Data format data logger+ The measured values are deposited on a memory card in a text folder in CSV format (separated with a comma). This data format can be opened and edited further in different user programs, e.g. MS Excel.

The name of the measurement file is always „HYDAC_SDMEU_Data_JJJJMM.csv“ and is found on the memory card in the following directory:

Every month, a new file is created.

The CSV file has the following structure:

Header Line Description

1 Product name 2 Software Version 3 Sensors 4 Measurement channels 5 Units

Records Column Description

A Date B Time C CS 1000 sensor connected

0 = False / 1=True D ISO > 4µm E ISO > 6µm F ISO > 14µm G ISO > 21µm H CS 1000 Status

0 = Undefined 1 = OK 2 = Error 3 = Flow 2 low 4 = ISO <9<8<7 5 = No value

I AS 1000 sensor connected 0 = False / 1=True

J Degree of saturation in % K Temperature in °C

14 OPC Variables / OPC Server The OPC server is a software product from the Moeller company. For details on its installation and configuration, see the the included instructions from the Moeller company.

In addition to the OPC server, the IP address of the SDMEU must be customized for the client. For this purpose, there is a file on the memory card called „STARTUP.ini.“ With this file and with the help of an editor, you can change the IP address as well as the subnet mask. (Default setting: IP address 192.168.119.60, Subnet mask: 255.255.255.0).

The INI file is located in the same file as the CSV files.

Structure of INI files:

After changing the address, you must:

- save the entries,

- Reinsert the card in the control unit and

- Reboot the system

See the Moeller company manual for how to test if the address has been correctly set, as well as for connecting the network cable.



The following variables have been defined or enabled for communication using the OPC.

Variable Data type Description g_CS_Connected BOOL CS connected Yes/No

g_AS_Connected BOOL AS connected Yes/No

g_HLB_Connected BOOL HLB connected Yes/No

PLC_PRG.CS_iso4Value WORD ISO >4µ (CS1000)




PLC_PRG.CS_stateValue WORD CS status as a number (see CSV file)

PLC_PRG.AS_SatValue INT Saturation percentage [%] (AS1000)

PLC_PRG.AS_TempValue INT Temperature [°C] (AS1000)

PLC_PRG.HLB_ViscoValue INT relative change in viscosity [%] (HLB)

PLC_PRG.HLB_DKValue INT relative change dielectric constant value [%] (HLB)

PLC_PRG.HLB_SatValue INT Water saturation degree [%] (HLB)

PLC_PRG.HLB_TempValue INT Temperature [°C] (HLB)

PLC_PRG.HLB_stateValue INT HLB status as a number (see CSV file)

These variables always give the current measured value/status and are not positioned according to the storage interval.

The corresponding symbol file is located on the memory card in the folder „…\Symbolfolie\ …“

15 Disposal / Recycling The packing material is to be disposed of as specified by law or national regulations. It can be reused.

When decommissioning and/or disposing of the SDMEU, adherence is to be maintained to local guidelines and regulations pertaining to occupational safety and environmental protection. This applies in particular to the oil in the unit, components covered with oil and electronic components.

After disassembling the unit and separating the various materials, they can be reused or disposed of properly in accordance with local regulations.



16 Sensor settings The connected sensors must be set up according to the following table for their correct operation with the SDMEU.

Sensor Program settings CS 1000 ANA.OUT = HDA.ISO

Measurement time = 60 sec.

AS 1000 None

HYDACLab none
