What to do if there is an internal data transmission error in my GasLab Security System?
- CChristina HughesAug 7, 2025
If you're seeing the error 'Er7' on the RDU of your GasLab Security System, ensure the RJ45 plug is correctly connected to the INPUT port of the RDU. If the issue persists, try pressing the reset button on the SEU or power cycling the system.
