Installation¶
Mechanical installation¶

Install the sensor: - In the last chain link at the fixed point (static area of the chain) - Centered between upper and lower opening bridge - Separation bar with wear block pointing towards the sliding part of the e-chain® - Use as a commercially available igus® separator; if necessary, replace separation bars with special separation bars

CAUTION!
There is a risk of crushing when installing the sensor. Please wear gloves or take other protective measures.
NOTE
Make sure that the e-chain® series embossed on the sensor matches the installed igus® e-chain®. Deviating sensors can be damaged if installed incorrectly.
NOTE
The board is housed in a separate housing which must be securely attached.
You can reset the sensor by holding a magnet on the top of that box for approx. 2 seconds.

Electrical installation¶
WARNING!
Immediately switch the device voltage-free in the event of damage (including to connection cables) and in case of interference or unusual phenomena such as arcs, sparks, smell of fire or noticeable noise.
- Disconnect all electrical energy sources from the device.
- Do not attempt to repair the device yourself.
- Report defects immediately, warn others and contact the responsible igus® branch.
Possible hazards: - Risk of electric shock - Danger of electric arcs - Injury hazard - Risk of component destruction
Always switch off the power supply before disconnecting or establishing electrical connections. Secure the power supply against reactivation.
Cables connected to EC. W.F / EC. W.F.P must not have exposed stripped wire ends. Ensure all connections are securely seated.

Commissioning and user interface¶
Commissioning¶
With i.Cee:plus II (delivered with IS. EC. W.F.P.SU.01.BETA)¶
The sensor is connected via UART directly to i.Cee:plus II. Further steps can be found in the instructions for i.Cee:plus II (QR code on the device).
Directly to PLC (delivered with IS. EC. W.F.SU.01.BETA)¶
- Provide 3 digital PLC inputs (typically 24 V DC inputs) and connect them to the 3 digital sensor outputs.
- Use the I/O ports as inputs; the contacts on the sensor are normally open.
- Evaluate the input states according to the following logic:
| I/O Port 1 | I/O Port 2 | I/O Port 3 | Remaining lifetime |
|---|---|---|---|
| 1 | 1 | 1 | 100… 76% lifetime remaining |
| 0 | 1 | 1 | 75… 51% lifetime remaining |
| 0 | 0 | 1 | 50… 26% lifetime remaining |
| 0 | 0 | 0 | < 25% lifetime remaining (chain replacement should be initiated) |
Process the state variables in your PLC program, e.g. by mapping the three states into your user interface.
Example:

Reset¶
You can reset the sensor by holding a magnet on the top of that box for approx. 2 seconds.

Troubleshooting¶
- Data transfer or I/O ports not available
- Check that all lines are connected, correctly and securely.
- If this does not help, please contact customer service.
- Sensor does not fit the e-chain®
- Contact customer service and ask for a suitable sensor.
FAQS¶
- How do I retrieve lifetime information?
- i.Cee:plus II displays lifetimes in the user interface.
- In the PLC, states are transmitted via I/O ports and processed in your PLC logic.
- Is it possible to download the sensor's data from the user interface?
- Nope.
- Is it possible to replace the wear block?
- Yes.

The applicable directives are listed in the EU declaration of conformity of the respective device.
Cyber Resilience Act (CRA) Notice The EC. W contains digital components. The security requirements of the EU Cyber Resilience Act (Regulation (EU) 2024/2847) apply to such products. The CRA stipulates that software and networked devices must be operated securely and kept up-to-date throughout their entire life cycle.
In order for you to use the EC. W can be used reliably and safely, please note:
- Install deployed firmware and software updates regularly.
- Use secure network and access settings.
- Change default passwords immediately after commissioning.
- Disable unnecessary interfaces or services.
If you notice a technical anomaly or a possible security vulnerability, please report it via the official igus support channel or via the service portal. The CRA also requires users to have access to information about security support, known risks, and update processes. For more details, please refer to the documentation of this product or contact your national market surveillance authority.
Note on the EU Dual-Use Regulation (EU) 2021/821 Individual electronic components and sensors in the EC. W may fall under the EU Dual-Use Regulation (EU) 2021/821, depending on the technical design. This ordinance regulates goods that can be used in both the civilian and military sectors.
A permit may therefore be required for export to countries outside the EU. Whether this is true depends on the target market, the application and the respective technical configuration.
Please check before passing on or exporting the product:
- whether there are export restrictions for your destination country,
- whether your application is considered security-critical or military-grade,
- whether a permit is required under applicable regulations.
For more information, please contact your national export control authority (e.g. BAFA in Germany) or consult the official EU documents.
