Truma SecuMotion Gastank
The Truma SecuMotion is a gas pressure regulator designed for liquid gas systems in vehicles, ensuring a uniform outlet pressure of 30 mbar. It features an integrated gas flow monitor (GSW) that automatically shuts off the gas supply if the nominal consumption is exceeded or if the downstream pressure drops below 27 mbar due to a pipe break.

Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Operational Fault | The gas consumption exceeded the nominal limit or a pressure drop occurred below 27 mbar (such as a pipe break or rapid pressure drop). | Ensure the extraction valve is open, then slowly press the GSW reset button (green button), hold/release slowly over 3 seconds, and verify the pressure point sets correctly. | DIY Safe |
Operational Fault | The gas flow monitor fails to trip when the provisional test line is opened. | Contact the Truma service centre. | Professional Intervention Required |
Frequently Asked Questions
Q: Can the SecuMotion be used in closed rooms, households, or on boats?
No, the use of this regulator in closed rooms (households, mobile homes, or on boats) is strictly prohibited.
Q: Is it permitted to operate the heating system while driving?
Yes, throughout Europe, a type-tested liquefied-gas heating system may be used while driving according to EU directive 2001/56/EC if the system includes a properly configured gas installation and regulator.
Q: How do I reset the gas flow monitor (GSW)?
Open the extraction valve, slowly press the green GSW reset button on the regulator, and slowly release it over 3 seconds. If no pressure point can be felt when pressed again, the regulator is ready for operation.
