If the burners is in operating position (phases 60 and 62), the actuators and the
speed are driven by the compound curves. Outside of the operating position, the
actuators and the speed are driven according to the
SpecialPositions
.
In the special positions, the actuators can be set independently.
Special positions are fuel specific and must be set separately for each fuel on dual
fuel burners.

Standby positions
Parameter
StandbyPos
determines the positions for phases 00 to 22.
Pre-purge position
Parameter
PrepurgePos
determines the positions of the air influencing actuat-
ors for pre-purge in phases 30 to 34. The exception is the auxiliary actuator3 (flue
gas recirculation), which only drives to pre-purge position from phase 32.
Ignition position
Parameter
IgnitionPos
determines the positions for the ignition process in
phases 36 to 54.
Individual ignition positions can be deleted in parameter
ResetIgnitPos
. If a
relevant ignition position is not defined, the W-FM initiates a start prevention at
heat demand. Se installation and operating manual of burner for the ignition posi-
tion.
