LIMIT OF USE

2.1

Intended use

The intended use of the sensor system consisting of base station and wireless sensors is ice

detection, temperature measurement and pitch angle measurement for wind turbines.

Icing and its layer thickness is detected by measuring the impedance on the surface. The

surface temperature is measured with an accuracy of ±0.25°C. The measurement data is

transmitted wirelessly to the base station with a range of at least 250m. The system consists

of a base station and several flexible sensors, which are applied on the rotor blades. The

sensors are glued to the blade surface (no drilling or similar - the rotor blade is not damaged)

and can also be retrofitted during regular inspections. The system measures icing at the point

where it happens. Observation of the effectiveness of existing anti- or de-icing solutions is

possible.

Detection of relative pitch angles is accomplished by measuring inertial sensing

(accelerations), which is an optional feature of the wireless sensor platform. This typically

features ±16g. The acquired data is transferred to servers of eologix sensor technology gmbh

during the application of the pitch angle measurement, which then calculate the relative pitch

angle by means of an algorithm and provide the determined value to the customer via a

dashboard.

A flexible solar cell ensures the energy supply, without light the function is maintained by

energy buffer for approx. 1000h.

The sensor is moulded on the blade erosion tape. Before installation, please carefully read the

installation information of 3M and prepare the blade surface accordingly. For more information,

visit the blade erosion tape manufacturer's website www.3M.com/wind for instructions on

applying 3M Wind Protection Tape 2.0/2.1 (W8750, W8751).

For compliance against DNV certificate, the number and position of sensors must be

coordinated with eologix (depending on turbine size, turbine type, application: "ice detection",

"ice free detection", "operation under ice load", "pitch angle measurement" etc.).

The product is built in accordance with the state of the art and recognized safety rules.

Nevertheless, its use may result in danger to life and health of the operator or third parties or

impairment of the product and other material assets. Intended use also includes observing the

operating instructions and complying with the maintenance requirements. Only use the

product when it is in perfect working order.

Use the product as intended and in a safety-conscious manner. If malfunctions or damage

occur that could impair safety, have them repaired immediately.

STRUCTURE

The following figure provides an overview of the structure of the product.

Figure 3 Overview of the sensor system

Pos. Component

Sensor units

Receiving unit (Base station)

The eologix sensor system is a blade-based measuring system. This means that a defined

number of sensors (depending on the application and, in some cases, the rotor diameter)

measure directly on the surface of the rotor blade. The sensors measure the temperature,

inertial data (optional) and capture the ice thickness directly at their application position, that

means at the surface of the rotor blades.

The measured data is transmitted wirelessly to a receiver (base station). The base station

receives the measurement data of all sensors, evaluates them and can be integrated via

various interfaces depending on the customer's requirements.

For the application of the relative pitch angle, the acquired inertial data is transmitted to servers

hosted by eologix, which use an algorithm to determine the relative pitch angles and then

transfer them to an online dashboard accessible to the customer. This means that a data

connection is also necessary for this application.

Figure 4 Overview transfer of measured data and interface integration (Ice application)

The following applications can be realised with the system according to DNV component

certificate CCA-DNVGL-SE-0441-00526-01

:

Ice detection (meaning, i.e., system stop because of icing)

Ice-free-detection (meaning automatic restart of the wind power plant once it is ice-free

after a system-stop because of icing)

No control of the system is necessary for the pitch angle application, i.e. it is purely a monitoring

tool, so no DNV component certificate is required in this case - but in order to obtain an external

qualification, a certification process is also currently being carried out for the pitch angle

application.

4.1.1

Function description base station

The base station receives the measurement data from the sensors by means of two antennas,

evaluates them and can be connected to the customer's system via various interfaces. The

antennas are mounted inside or outside the nacelle of the wind turbine, depending on its

condition. With an existing internet connection of the base station, it is also possible to store

the measurement data online (on own servers at the location of eologix in Graz, Austria) and

to display historical data by means of visualisation (see Chapter 6.4).

Possible interfaces

2 x or 3 x relay output (system status ok/not ok, ice stop yes/no, restart yes/no)

ModBus TCP/IP

CAN

RS485

Network interface 1 for connection to eologix online system

Network interface 2 for connection to OEM control or SCADA system

Further interfaces possible on request

The power consumption of the base station is typically 5 W (maximum 10 W).

Function principle

The eologix BET214 base station is a receiving unit for the eologix CET214 sensors and also

other compatible ice and temperature sensors. Typical installation positions of the base station

are in the nacelle or near the tower but are not limited (also e.g. sub-station or transformer

station). One base station is used per turbine.

The base station consists of the electrical cabinet and one or more receiving antennas,

depending on the designated installation. The base station antenna(s) receive(s) the signal

from the CET214 sensors (or compatible sensors). The base station stores and sends the data

to the eologix server for data processing or data usage for the customer. Furthermore,

switching signals are generated or various bus signals can be provided for turbine control.

The BET214 base station receives data packets from the sensors. The signals for the switching

relays are generated from these data packets:

System OK/ System NOT OK,

Ice-stop / NO ice-stop,

Restart / NO restart.

Optional: Inertial data (transmission to eologix server for further calculation of relative

blade angle errors)

OperationandServiceManual_V1_4_EN_eologix

eologix.com 42 | 125

The data is also transferred online (to the eologix server) for further evaluation of the data. In

addition, various bus systems are supported by the system.

Function description ice measurement

The eologix CET214 is a wireless sensor for measuring ice, temperature and inertial data. It

uses an SRD communication band powered by a photovoltaic cell as a standard power supply

in combination with accumulators (to bridge nights and longer icing times). The sensor unit is

completely isolated and requires no external power supply. The sensor controller has the

following two tasks:

Importing and processing the measured date and

wireless transmission of the data.

The ice detection is based on an integrated circuit for impedance measurement.

The base station BET214 or a BET214-compatible unit is required.

The following signal levels including their meaning are measured and output per sensor for ice

detection: The following images were created in an ice wind tunnel and show the

corresponding ice thickness per signal level as an example:

Function description temperature measurement

The surface temperature is measured by the sensor with an accuracy of ±0,25°C in the range

of -40°C bis +85 C.

4.2.5

Function description pitch angle measurement

The sensor system can also be used for relative pitch angle measurement. In contrast to

ground-based systems, the sensor system from eologix measures continuously.

There is a continuous measurement of the pitch angles, but because of different possible

occurrences (e.g. strong gusts, etc.) a result is only guaranteed once a week. For a successful

evaluation, the system must generally be in operation (no standstill and no spinning).

For installation and commissioning, an internet connection and a power connection are

required. If the customer cannot provide a LAN, the manufacturer can provide a SIM card as

INSTALLATION

The installation of the sensor system is covered in the following chapters. This includes

requirements for transport, storage, the installation site, mounting and commissioning of the

base station and sensor.

The base station can be attached to a mounting location in the nacelle. See chapter 5.4

The sensor is delivered applied to a wind blade protection tape; by means of this tape and a

self-adhesive back side of the sensor, installation on the rotor blade is carried out at the same

time. Installation is possible at the manufacturer, on the construction site and also for already

erected wind turbines. See chapter 5.6

5.1

Transport

If the product is not delivered by eologix sensor technology gmbh, appropriate packaging must

be chosen for transport, as well as an appropriate transport company. The product

components must be packaged in appropriate transport containers and appropriately secured

for transport.

5.2

Storage

Regarding storage of the product, the following must be observed.

Depending on the ambient conditions, the product must be protected accordingly.

If necessary, the components must be treated accordingly to protect them against

corrosion damages.

Storage of the sensors

The sensors are exposed to light while in storage at the manufacturer's and are

therefore ready for use upon delivery.

Regarding storage at the operator's, it must be ensured that the batteries are not deeply

discharged by longer storage at a dark location.

If the sensors are stored at darkness for a period of time that exceeds the maximum

operation time at darkness, the sensors must be charged in conditions similar to

daylight or sunlight at least once for four hours within two weeks. This means that, in

the event of permanent storage, the charging process must be repeated at least every

two weeks for four hours. If in doubt, please contact eologix sensor technology gmbh.

Application positions automatic restart

In this mode, another signal (in addition to the "stop" signal) is generated according to the

algorithm as per the DNV component certificate, which signals the system to restart

automatically after a stop due to icing. I.e. the system detects when there is no more ice on the

rotor blades of the turbine and signals the turbine to restart it.

In an eologix:restart system, the necessary positions for ice detection are covered several

times. This means that every eologix:restart system is also suitable for the ice detection

function. The number of sensors used in the eologix:restart system depends on the size of the

wind turbine. The following system size (i.e. number of sensors) is used depending on the

blade length:

Application of a sensor

The sensor is delivered applied to wind blade protection tape; by means of this tape and a

self-adhesive back side of the sensor, application on the rotor blade is carried out at the same

time. The wind blade protection tape by 3M (W8751 resp. W8750) that is used has been used

for more than ten years in wind power to protect the leading edge.

The sensors can be applied by the manufacturer, on the construction site (before lifting the

blades) as well as at existing systems (retrofitting by means of manlift or industrial climbers).

Application can be carried out by the customer themselves. Training by eologix necessary.

Clean surface & apply Adhesion Promoter W9910

Step 2: Clean surface and apply adhesion promoter

The marked mounting surfaces must be cleaned of dirt, dust, grease or silicone. If necessary,

use sandpaper (grit 250 - 500) to smoothen the surface. Any cracks must be filled beforehand

to create a suitable base surface before the sensors can be applied.

Do not cut pieces out of the sensor tape without prior consultation with eologix.

The sensor could be damaged, or the adhesive tape might lose its adhesion.

5.6.6

Adjusting

The degree on the wind rose, which points to the root of the rotor blade (in this example: 90°)

must be noted in the documentation (see also section "Documentation").

Distance from the trailing edge of the rotor blade

The following figure explains the distance from the trailing edge of the rotor blade (Distance

trailing edge (%)).

The distance from the trailing edge of the rotor blade is given in [%] (see mounting positions

(Distance trailing edge (%)):

OperationandServiceManual_V1_4_EN_eologix

eologix.com 73 | 125

How the sensor is adjusted depends on the application position in relation to the rotor blade's

trailing edge. The distance from the rotor blade's trailing edge is given in [%]:

100% = LE - Distance trailing edge (%)

Sensor is mounted directly on the leading edge of the rotor blade (only 0° or 180°

orientation is allowed)

>= 90% = LE - Distance trailing edge (%)

Sensor is mounted as close as possible to the leading edge of the rotor blade

(only 90° or 270° orientations are permitted). The erosion protection foil of the

sensor ("thin" area) must always be taped over the leading edge. See section:

"Important notes".

50% = MID - Distance trailing edge (%)

Chordwise in the middle between the leading and trailing edge of the rotor blade.

<= 10% = TE - Distance trailing edge (%)

The erosion protection tape must cover over the trailing edge of the rotor blade

(i.e. the entire sensor plus tape must be stickedf on one side of the blade)

The wind rose shown on the sensor is used to correctly align the sensor.

Wind rose (the number pointing in the direction of the rotor blade root is noted in the

documentation).

Direction to rotor blade root (in this example 180°)

Figure 34 Wind rose on the sensor

W A R NIN G

There must be a distance of at least 1 m between the sensors and lightning receptors, otherwise

they might be damaged.

Avoid areas on the rotor blade where the distance between sensor and lightning arresters

within the blade is less than 3 cm.

N O T ICE

If the sensor is applied directly at the rotor blade's leading edge (>90%), the wide side of the

tape must be applied over the rotor blade's leading edge: wind rose 90° (as shown below)

Adhering

Step 5: Apply the sensor correctly.

In this step, the sensor with the now self-adhesive back is glued onto the rotor blade in the

correct position (according to the specified mounting positions and the following explanations).

Figure 36 Adhering the sensor

N O T ICE

The edges of the sensor tape may especially at the rotor blade's leading edge not be directly

exposed to wind flow - in that case, it may be necessary to apply an additional tape after

consultation with eologix sensor technology but it has to be ensured that no second tape layer

is applied onto the sensor area (marked with two black triangles)

Step 6: Applying the assembly spray.

Wet the surface of the rotor blade with installation spray (75% water & 25% isopropanol): the

surface on which the erosion protection tape will be placed should be completely wetted.

N O T ICE

There may not be any liquid underneath the sensor. It must, as outlined in step 5, already be

firmly adhered to the rotor blade before the application spray is applied.

Step 7: Remove the protective tape from the surrounding Wind Protection Tape.

Figure 38 Remove protective tape from surrounding

In step 7, remove the transparent protective tape (patterned with "3M "). Now also spray the

sticky side of the Wind Protection Tape with mounting spray. Then apply the erosion protection

tape to the blade surface.

Step 8: Strike out application solution

Spread the Application Solution between the tape and the rotor blade surface with the spatula

- For this step 3M recommends the "Wet or Dry Rubber Squeegee Part.No 05517".

Only the erosion protection foil around the circuit board may be worked on with the spatula!

Inspection

Step 9: Checking the sensor and removing the marking

After mounting, check the sensor with the eologix handheld reader. Each sensor ID displayed

on the handheld reader confirms the function of this sensor. If a sensor is not displayed even

after one hour in daylight, proceed as follows:

Remove sensor (as seen in Chapter 8.3)

Attach a new sensor.

Send the defective sensor including the picture documentation of the attachment and

removal back to eologix in order to clarify the cause of the defect

After the sensor has been successfully tested, the piece of insulating tape used for must be

removed again.

Sealing

Step 10: Edge sealing

Make sure the surface is dry. Use 3M Wind Protection Tape Edge Sealer W2600 with the 3M

EPX Applicator to seal the edge between the tape and the rotor blade (as shown in the 3M

video

Edge Sealer W2600. Furthermore, ensure dry weather conditions (no wet rotor blade surface,

no rain, condensing mist, etc.) before and during installation as well as for a few hours

afterwards (curing time which is temperature dependent). The Edge Sealer must NEVER be

exposed to moisture before and during curing.

Once the Edge Sealer has been applied, the sensor installation is complete. Now all steps of

the mounting process are completed. Now follows the documentation of all glued sensors.

OPERATION

The following chapters provide an overview of the operation of the product.

6.1

Use

The eologix ice detection system is certified by DNV. The certificate distinguishes between

three operating modes

Ice detection, meaning system stop because of icing

Automatic restart, meaning automatic system start if ice-free

Operation under ice load, meaning by means of measurement of ice thickness.

Only the first two operating modes will be covered in detail below. Customer-specific variations

of the sensor configuration (especially additional equipment or individual equipment for

specific purposes) are always possible.

6.1.1

Ice detection

Algorithm ice detection

The si ICE meaning: ice is detected and the system must be stopped) is output, if

Redundancy ice detection

In accordance with the certificate, the system requires at least two sensors at the tip and one

sensor at the

eologix:safe (9 sensors)

In this mode, a signal is generated according to the algorithm in the DNV component

certificate, which signals the system to stop due to safety-relevant icing. The positions of the

sensors are shown in chapter 5.5.1. The number of sensors does not depend on the blade

length.

OperationandServiceManual_V1_4_EN_eologix

eologix.com 82 | 125

6.1.2

Automatic restart

Algorithm Automatic restart (Restart)

As soon as a sensor delivers "SIGNAL LEVEL 5" or a sensor delivers "SIGNAL LEVEL 4" or two

sensors on one blade deliver "SIGNAL LEVEL 3", the signal "AUTOSTART NOT OK" is output.

If this is not the case, the signal "AUTOSTART OK" is output and the system can restart

automatically.

Redundancy Automatic restart (Restart)

The function "Ice-free detection" can be continued as long as:

at least 66% of all sensors of the minimum requirement are active,

at least 2 blade tip sensors (sensors at positions >70% of the blade length) are active on

2 blades,

at least one sensor is active every 30 m on each leading edge.

If not all of the above conditions are met, the signal "AUTOSTART NOT OK" is always output.

Here, too, each sensor is redundant at least once (i.e. each sensor position is covered by at

least one other sensor).

eologix:restart (number of sensors depending on blade length)

For the detection of ice-free conditions and thus the automatic restart, a higher number of

sensors must be used and this also depends on the blade length. In the following, the required

number of sensors according to the certificate is listed for exemplary wind turbine

manufacturers and blade lengths:

Turbine type Blade length Number of sensors

X70 34 m 21

X82 39,5 m 21

X90 43,5 m 21

X115 56 m 21

X126 61,5 m 24

X136 66,5 m 24

X180 88 m 24

With every eologix:restart system, the necessary positions for ice detection are covered

several times. This means that every eologix:restart system is also suitable for the ice detection

function.

OperationandServiceManual_V1_4_EN_eologix

eologix.com 83 | 125

6.1.3

Operation under ice load

Operation under ice load, i.e. due to the continuous ice thickness measurement, the system

can continue to be operated in non-safety-critical areas up to a certain degree of icing. Further

information on this is available on request.

6.2

Handling

The product is set up via the interface in the course of commissioning. Afterwards, no further

operational steps are necessary, the eologix sensor system is fully automated.

6.3

Assessment of probability of failure

DNV certification requires a probability of failure assessment in accordance with ISO

13849:2008.

Redundancy of the sensors

Redundancy of the receiving units:

o

2 antennas and

Relais outputs

Up to 3 SPDT safety relais outputs are optionally available at the base station at dedicated

connectors. Please refer to the connection description available separately.

Switching is configured as fail-to-safe, i.e. in case of power-loss at any point in the base station,

Depending on the system configuration, the following signalling is implemented.

iceOutput denotes a signal to stop the turbine. No information on restart options is given. If

this signal falls back, it merely means that a turbine stop is not required anymore. If, however,

the turbine has already been stopped, it must not be re-started automatically.

iceOutput reflects the state whether the turbine is free of ice. In this configuration, an

automatic turbine restart is possible.

All the other values of the respective sensor are from that last message.

If any sensor information cannot be accessed, the respective registers of that sensor will show

an error value as outlined below. These values are chosen to be out-of-band of valid values.

This can occur after a powerup or reboot if a sensor has not yet been received at least once.
