Pre-aeration B Contrary to the "Pre-aeration A" state, this state is skipped if the last switch-off of the MPA was a regular switch-off with successful valve tightness test. Moreover, no power failure must have been occurred since the last switch-off.
  • Page 18 7.6 State description MPA 5111 State xx Designation Description In this mode, the MPA can be modulated via several types Standard mode (see P70 to P76, especially P72). A voluntary switch-off after a defined time can be activated (P70). If this time is set to a maximum of 23 hours and 59 minutes, the MPA is in the intermittent mode.
  • Page 19 7.6 State description MPA 5111 State xx Designation Description The MPA switches to this state if a lack of gas on the GD- Waiting program WVPS (depending on P46) or an open safety chain has been detected during startup. The MPA remains in this state for a certain waiting time and then carries out another restart test.
