2 Safety information
The safety information in this document refers only to an individual product. Potentially dangerous conditions can arise in
combination with other plant components, which need to be considered on the basis of a risk analysis. The operator is re-
sponsible for the production of the risk analysis and for compliance with the resulting precautionary measures and regional
safety regulations.
The document contains fundamental safety information that must be observed during commissioning, operation and mainten-
ance. Non-compliance with these instructions may cause:
•Personal hazard due to electrical, mechanical and chemical effects.
•Hazard to nearby equipment.
•Failure of important functions.
•Hazard to the environment due to the leakage of dangerous materials.
The safety information does not take into account:
•Unexpected incidents and events, which may occur during installation, operation and maintenance.
•Local safety regulations which must be adhered to by the operator and by any additional installation personnel.
Prior to commissioning:
1. Transport and store the product correctly.
2. Do not paint the bolts and plastic parts of the product.
3. Carry out installation and commissioning using trained personnel.
4. Provide adequate training for installation and operating personnel.
5. Ensure that the contents of the document have been fully understood by the responsible personnel.
6. Define the areas of responsibility.
7. Observe the safety data sheets.
8. Observe the safety regulations for the media used.
During operation:
9. Keep this document available at the place of use.
10. Observe the safety information.
11. Operate the product in accordance with this document.
12. Operate the product in accordance with the specifications.

3.2 Description
The GEMÜ 4240 combi switchbox is suitable for mounting to pneumatically operated linear actuators. The position of the
valve spindle is reliably detected electronically and reported via microswitches or proximity switches, using play-free and non-
positive mounting. Integrated pilot valves enable direct activation of the process valve connected to them. The product has
been designed specially for valves with a stroke of 5 to 75 mm.
3.3 Function
The GEMÜ 4240 combi switchbox indicates the current position of the valve. When the valve is opened, the spindle in the
combi switchbox moves upwards and indicates that the valve is OPEN using the communication interface. When the valve is
closed, the spring in the mounting kit presses the spindle in the combi switchbox downwards and indicates that the valve is
CLOSED using the communication interface.

4 GEMÜ CONEXO
Order variant
In the corresponding design with CONEXO, this product has an RFID chip (1) for electronic identification purposes. The posi-
tion of the RFID chip can be seen below. The CONEXO pen helps read out information stored in the RFID chips. The CONEXO
app or CONEXO portal is required to view this information.
