What should I do if my Carel GDWRI20A00 unit displays a 'Sensor AFE read fault (EC only)'?
If your Carel Gas Detectors unit displays a 'Sensor AFE read fault (EC only)', this indicates that it cannot read from the EC sensor AFE. You should check the sensor connection and/or replace the sensor module.
What should I do if my Carel GDWRI20A00 unit displays a system flash memory read error?
A system flash memory read error on your Carel Gas Detectors device indicates an issue while reading the internal flash memory. Try power cycling the device. If the error continues, contact service.
What should I do if my Carel GDWRI20A00 unit displays a system flash memory write error?
A system flash memory write error on your Carel Gas Detectors device indicates an error writing to the internal flash memory. Try power cycling the device. If the error continues, 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.
What should I do if my Carel GDWRI20A00 Gas Detectors unit displays a 'Sensor AFE write fault (EC only)'?
If your Carel Gas Detectors unit displays a 'Sensor AFE write fault (EC only)', this indicates that it cannot write to the EC sensor AFE. You should check the sensor connection and/or replace the sensor module.
What should I do if my Carel GDWRI20A00 unit displays a 'Sensor UART read fault'?
If your Carel Gas Detectors unit displays a 'Sensor UART read fault', this indicates that it cannot read from the sensor UART. You should check the sensor connection and/or replace the sensor module.
What does a Bluetooth fault mean on my Carel GDWRI20A00 Gas Detectors, and how can I fix it?
A Bluetooth fault on your Carel Gas Detectors device indicates that a Bluetooth module error has been detected. Try power cycling the device. If the issue persists, contact service.
What does 'Analogue output fault' mean on Carel GDWRI20A00 Gas Detectors (GDWB only)?
An analogue output fault on your Carel Gas Detectors (GDWB only) indicates an error updating the DAC value. Try power cycling the device. If the issue persists, 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 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.
