Faults 

The PX2 detector includes a diagnostic module for the continuous monitoring of the relevant functions and 
parameters  as  well as a  processor-independent  watchdog. These  features  set the PX2 device into the safe 
mode  "Fault"  in  case  of  an  internal  or  external  error.  The  following  table  6.1  shows  all  possible  errors, 
possible causes, the related troubleshooting and the resulting device status. 
When the cause of the error has been eliminated, the PX2 gas detector restarts with the diagnostic mode on 
its own. It is not necessary to acknowledge the error message. 
If an error occurs, it is output in the option with display instead of the measured value and in the menu error 
status in plain text. If there is more than one error, it is output with a cumulative, bit-coded error code.
