All relevant Ax60+ document information can be found on the Analox Sensor Technology Website, take a look at the Ax60+ product page.


The Ax60+ is primarily a breathing air device, as such, the CO2 sensor unit alarms are restricted to only trigger in the 'high-going' direction. If a user changes the alarm 'going' to 'low-going' a FLT16 will ensue. 


To clear this fault the following steps should be followed (be aware that only a short period of non-alarm time is available so you'll need to be quick!!):

  10. Select the alarm that had the alarm 'going' changed (press cycle to move the arrow selector over until the relevant alarm is identified and press the Accept/test button)
