FMS Fault Correction
Parameters (P)
Aids O control
2
P33
Deactivation time for O regulation in the case of curve switching during
2
Parameter 903
operation.Switching during burner operation. The time starts from when the
Level 1
actuators have reached the "new” position.
The regulator is deactivated as soon as the switch-over starts, and the
correction value for deactivated regulation is output (parameter 902).

Parameter 904
Delay time for activating the O regulator after the flame appears.

P35
These parameters can be used to deactivate the O regulator below and
2
Parameters 914/915
above a defined load value. The correction value for "Deactivated O

Level 0
regulation” is output.

P36
These two parameters serve to equalise the O regulator module with an O

Parameters 919/920
meter coupled via an analogue signal (4...20 mA).
Level 1
Taking into account probe control during pre-ventilation, it is
recommended to set a measurement range of 0...25 vol.% O .
2

P37
These parameters are used to set the O monitoring bands for base and full
2
Parameters 923 to 930
load, referenced to the O2 target value in %.

Parameters 931 to 934
Example:
Level 1
O target value 3 vol.% O

50% below threshold specified
Shut-down limit < 1.5 vol.% O .
