9.2.3 Prepurging
This position is approached in phase
Traveling to prepurging (24).
The position can be set via the following parameters:
Parameter Actuator
501.01 Prepurge position fuel actuator
502.01 Prepurge position air actuator
503.01 Prepurge speed VSD
No. Parameter
222
Gas: Prepurging
0 = inactive
1 = active
262
Oil: Prepurging
0 = inactive
1 = active
9.2.4 Ignition
The ignition position is approached in phase
Traveling to the ignition position (38).
The position is set via curve parameterization under
P0. In modulating operation, this
point is assigned to an output of 10%.
9.2.5 Postpurging
This position is approached in phase
Traveling to postpurging (72).
The position can be set via the following parameters:
Parameter Actuator
501.02 Postpurge position fuel actuator
502.02 Postpurge position air actuator
503.02 Postpurge speed VSD
