P11 Restart
attempts
Here you can set the number of re-
start attempts the MPA is allowed to
be carried out before the fault switch-
off is activated (state "Error").
The anti-oscillation counter is reset
to this value as soon as the MPA has
reached the state "Standard mode"
or the MPA has been unlocked.
The number of restarts is internally
counted by means of the anti-oscil-
lation counter.
P12 Restart
attempts due to a
missing flame
The number of restart attempts
(P11) can be limited here for the
special case that no flame has been
generated during the safety time.
For this purpose, the restart coun-
ter is internally implemented. The
anti-oscillation counter as well as
the restart counter are activated!
Example:
P11 = 5, P12 = 1
During the first start phase, no
flame is generated → 1. Restart
attempt → Error idle state control
LDW → 2. Restart attempt → Error
idle state LDW 3. Restart attempt
After the third restart attempt LDW
OK, there is still no flame Automatic
burner control is locked.
P13 Restart
attempts after the
flame has gone out
The number of restart attempts
(P11) can be limited here for the
special case that a flame has gone
out.
For this purpose, also the restart
counter is internally used. The anti-
oscillation counter as well as the
restart counter are activated!
Example:
P11 = 5, P13 = 1
Flame gone out during operation
1. Restart attempt Error Idle state
control LDW 2. Restart attempt
Error Idle state control LDW 3. Re-
start attempt No flame is gener-
ated after the third restart attempt
LDW OK Automatic burner control
is unlocked.
