Cyber Resilience Act (CRA) Notice
This product contains digital components. For such products, the Security requirements of the EU Cyber Resilience Act (Regulation (EU) 2024/2847). The CRA specifies that software and connected devices must be used across the entire life cycle must be operated safely and kept up to date.
To ensure that you can use your system 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 see a technical anomaly or a possible security vulnerability , please report them via the official igus support channel: security@[manufacturer].com or via the service portal.
The CRA also requires users to have access to information on: Receive security support, known risks, and update processes. For more details, please refer to the documentation of this product or with your national market surveillance authority.
Note on the EU Dual-Use Regulation (EU) 2021/821
Individual electronic components and sensors in this product may vary depending on the fall under the EU Dual-Use Regulation (EU) 2021/821. This ordinance regulates goods that are used in both civilian and military area.
For export to countries outside the EU, a permit can therefore be obtained may be necessary. 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 in the official EU documents.)
CAUTION!
Do not open the device when wet or with wet hands. Be sure to make sure that the polarity of the battery is correct (see Figure 1 on the right, red marking). Otherwise, there is a risk of fire and explosion. Replace the battery only and exclusively with a type with the exact same values (battery type: CR1225/3V).
NOTE!
The i.Sense:modul II may only be maintained by qualified specialists. Please refer to Chapter 1.2 (Qualified Personnel). If hardware problems occur due to unqualified personnel, the warranty will be void. If you experience other hardware problems, please contact our customer service (see page 30). Used batteries do not belong in household waste. The batteries must be handed in at a collection point for used batteries.
In the i.Sense:modul II, on the circuit board, there is a CR1225 3V battery (see red marking Figure 1 on the right). For the period in which the 24V supply voltage is switched off, the battery ensures that the date and time are maintained. The battery must be replaced as soon as the status light-emitting diode labeled "Replace Battery" lights up yellow (see red marker Figure 1 on the left).

Figure 1: IS. EC. U04.04.01.0 - Battery
When you change the battery, you completely de-energize the device. Disconnect any connected terminals on the device and remove the device from the DIN rail. Remove the front sticker and unscrew the 4 screws on the right unglued half of the case.
(If the sticker is damaged during opening, please contact igus® customer service to order a replacement for a replacement). Then the left and right sides of the case can be carefully pulled apart on the front and back with the thumbs from the top to the bottom.
NOTE!
After a battery change, the date/time parameters are lost. To apply a new date/time, all parameters must be re-entered in the graphical user interface in configuration mode. Please proceed as described in Chapter 7.3 "Operating the User Interface" on page 19.
The igus® smart plastics condition monitoring concept helps to avoid unplanned system downtimes due to breakage or blockage of the igus® e-chain system®. i.Sense:modul II is a microprocessor-based DIN rail module (diagnostic tool) for the continuous evaluation of connected i.Sense sensors. Eight potential-free contacts enable a rapid machine reaction to unexpected operating conditions of the igus® e-chain® system. The configuration dashboard and sensor data download can be accessed via USB and WiFi connectivity.
DANGER!
The i.Sense:modul II is not a safety component within the meaning of the Machinery Directive. The device is intended exclusively for the prevention of blockages or breakages on igus® e-chain systems®, and is not suitable for the prevention of personal injury during machine / plant operation. Failure to do so can result in serious personal injury up to death or serious, irreversible injuries as well as property damage.
Use the appliance only as intended. The protection of persons is not guaranteed if the device is not used in accordance with its intended use.
igus® GmbH is not liable for damage caused by improper use.
Read this original user manual before using the device. Knowledge of the original operating instructions is part of the intended use.

Sensors¶
Terminals X1/X2 2mV/V Force Measurement¶
CAUTION!
The device is designed in such a way that forces up to a maximum of 90% of the rated load can be monitored. To simplify, a mass of 1t corresponds to a force of 10000N and a mass of 2t corresponds to a force of 20000N. When using a load cell with a nominal capacity of 1t and 2t, the maximum adjustable force limits are as follows (see Table 1). Setting force limits beyond 90% of the nominal capacity is not permitted.
| Nominal Capacity Load Cell | Maximum adjustable force limits 90% of rated capacity |
|---|---|
| 1t | 9000 N |
| 2t | 18000 N |

CAUTION!
The device is designed to measure positions within the nominal length. When using a position sensor with a nominal length of 99mm, the lower position limit must be >0mm (e.g. 10mm) and the upper position limit must be <99mm (e.g. 90mm). Setting position limits <= 0mm for the lower position limit and >= 99mm for the upper position limit is not permitted. The same applies to position sensors with other nominal lengths.
