2021
Flow sensor failure. Circuit
failure in the Flow system
N
Sensor cartridge flow sensors have failed. This may occur as the result of
powering the unit from the USB connector, i.e. without the main power supply
connected, as the flow measurement electronics require the main power supply
input to be present in order to function correctly. Otherwise, if the main supply
input is present and within specified limits, replace the sensor cartridge and re-
commission.
2022 Temperature sensor failure
N
Sensor cartridge temperature sensor failed. Replace sensor cartridge and re-
commission.
2023
Humidity sensor fault.
Failure in the Humidity
Interface
N
Sensor cartridge humidity sensor failed. Replace sensor cartridge and re-
commission.
2140
Gas over range. Sensor
more than 10% (of range)
above the defined
maximum range
Y
An ECO gas sensor was exposed to a gas concentration greater than 110% of
scale. Click reset to clear. If unable to clear re calibrate sensor cartridge. If error
persists replace sensor cartridge.
2141
Less than 30 days sensor
life remaining
Y
The sensor cartridge is within 30 days of the end of it's life. Replace sensor
cartridge and re-commission
