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).
______________________________________________________________________________________________________
P34
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
2
Level 0 regulation” is output.
______________________________________________________________________________________________________
P36 These two parameters serve to equalise the O regulator module with an O
22
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 %.
Level 2 For details see page 49.
Parameters 931 to 934 Example:
Level 1 O target value 3 vol.% O
2
2
50% below threshold specified
Shut-down limit < 1.5 vol.% O .
2
______________________________________________________________________________________________________
P38 This parameter can be used to set the demand threshold for the "Dynamic
Parameter 936 probe test” function control.
Level 1 Factory setting:
2 Z 0.2 vol.% O
2
0 Z means "Dynamic probe test” switched off.
