What does a GPIO fault mean on my Carel GDWRI20A00, and how can I fix it?
A GPIO fault on your Carel Gas Detectors device indicates an error detected on the GPIO pin. It is recommended to contact service.
What does it mean when my Carel Gas Detectors unit displays a 'Full-scale calibration fault'?
If your Carel Gas Detectors unit displays a 'Full-scale calibration fault', it means the full-scale calibration has failed. You should acknowledge the failed calibration via the app or by activating and holding MAG#2.
What does it mean when my Carel GDWRI20A00 Gas Detectors unit displays a 'Zero calibration fault'?
If your Carel Gas Detectors unit displays a 'Zero calibration fault', it means the zero calibration has failed. You should acknowledge the failed calibration via the app or by activating and holding MAG#1.
What does it mean if my Carel GDWRI20A00 says 'Sensitive element output'?
If your Carel Gas Detectors displays a 'Sensitive element output' message, it means the sensitive element was not found. In this case, you should check the sensor connection.
What should I check if my Carel GDWRI20A00 Gas Detectors unit displays a sensor temperature fault?
If your Carel Gas Detectors unit is showing a sensor temperature fault, this means the temperature cannot be read or is out of specification. Ensure the sensor is operating within the specified temperature range and check the sensor connections.
What to do if my Carel GDWRI20A00 unit experiences a Sensor EEPROM read fault?
If your Carel Gas Detectors unit reports a sensor EEPROM read fault, this indicates an error reading from the sensor EEPROM. You can try power cycling the device, checking the sensor connection, or replacing the sensor module.
What does it mean if my Carel Gas Detectors unit shows an invalid system configuration, and how can I resolve it?
An invalid system configuration error on your Carel Gas Detectors device indicates a system configuration error. Try power cycling the device. If the issue persists, contact service.
What to do if my Carel Gas Detectors unit shows a negative gas concentration fault?
If you are seeing a negative gas concentration fault on your Carel Gas Detectors, it means the sensor output has drifted too far in the negative direction. You should start zero calibration via app or by activating and holding MAG#2.
What should I do if my Carel GDWRI20A00 unit displays a system flash memory CRC fault?
If your Carel Gas Detectors unit displays a system flash memory CRC fault, this indicates an internal flash memory CRC error. Try power cycling the device. If the error continues after the restart, contact service.
What does it mean if my Carel GDWRI20A00 Gas Detectors unit shows a Modbus fault, and how do I fix it?
A Modbus fault on your Carel Gas Detectors device means a communication error has been detected. Try power cycling the device. If the problem persists, contact service.
