MPA 5111
State xx Designation Description
36 Waiting program The MPA switches to this state if a lack of gas on the GD-
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. The number of
restart tests is congurable (P90).
The waiting time duration depends on the number of wait-
ing times that have been executed before. The rst time,
the waiting time is 2 minutes, the second time 5 minutes
and the third time 1 hour and afterwards a time duration
dened by a parameter is applied. If the waiting time de-
ned by a parameter (P91) is shorter than the rmly dened
times of the rst 3 restart tests, these are also reduced to
the parameter-dened time.
The respective waiting time can be interrupted by setting
the temperature controller to OFF (OFF depends on the
operating mode in P15!).
The waiting program start from the beginning if the auto-
matic system
a) has been separated from the mains,
b) has been unlocked or
c) has reached the standard mode after a restart test.
