Parameter Designation Description Setting / Examples
P11 Field bus address
conguration
Setting the bus slave address of MPA
If an invalid address for the connect-
ed bus module is set and the MPA is
in automatic mode, it restarts (error
0x18).
If an invalid value for the connected
bus module is set and the MPA is in
parameter mode, an error message
is generated.
During operation and error messag-
es, the current bus address may be
seen by pressing the ← key.
Value range:
OFF (no eldbus available)
1 to 254
(e.g. Probus adjustment range from
1 to 126)
Note: A modied value for this param-
eter is not applied before a restart.
P12 Number of restart at-
tempts or anti-oscilla-
tion counter
Number of restart attempts of the
MPA.
After a failed last start, the MPA locks
in fault switch-o (state 0 "error").
The anti-oscillation counter is reset
when returning to operating state or
when unlocking the MPA.
Value range:
0-5 attempts
P13 Number of restart
attempts when ame
is missing after the
start-gas ame prov-
ing period
The number of restart attempts after
creating a ame (P12) can be lim-
ited for the case that the ame is still
missing after the rst safety time for
start-up.
The restart counter and the anti-
oscillation counter are reset when
changing to the operating state or af-
ter unlocking.
Value range:
0-5 attempts
Example:
P12 = 5, P13 = 1
Flame is still missing after the rst
restart → 1. Restart attempt → Error
idle state control LDW → 2. Restart
attempt → Error idle state control
LDW → 3. Restart attempt → LDW
OK after the third attempt, there is
still no ame → Automatic system is
locked although the number of re-
start attempts (P12) has not yet been
reached but the number of restart at-
tempts after missing ame has been
reached.
P14 Number of restart at-
tempts after a ame-
out or missing ame
after the second
safety time for start-up
The number of restart attempts (P12)
can be limited for the case that there
is a ame lift-o or that the ame is
still missing after the safety time for
start-up.
The restart counter and the anti-
oscillation counter are reset when
changing to the operating state or af-
ter unlocking.
Value range:
0-5 attempts
Example:
P12 = 5, P14 = 1
Missing ame during operation →
1. Restart attempt → Error idle state
control LDW → 2. Restart attempt →
Error idle state control LDW → 3. Re-
start attempt → After the third attempt
LDW OK, there is still no ame → Au-
tomatic system is locked.
P15 Locking with open
safety chain
If the safety chain is not closed, the
MPA waits in state 35 (safety chain
open).
If the adjustable time (P20) has
lapsed and the safety chain is still
open, the system changes to fault
lock due to an error or restarts (de-
pending on the anti-oscillation coun-
ter).
This setting is also valid if the safety
chain is opened after state 4.
Setting:
0: Restart attempt depending on the
anti-oscillation counter
1: Immediate fault lock
