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.
