FMS Commissioning Correction
Factory setting:
Expansion factor 10; ^ 1.0, i.e. no weighting
Expansion factor > 10; the correction increases
with rising burner output;
Expansion factor < 10; the correction decreases
with rising burner output.
For details see VMS Commissioning instructions, under Auxiliaries, p. 30.
ATTENTION:
When applying O corrections, make sure that the combustion limits
2
are observed even with the maximum correction applied (100%). For
details see page 67, "Checking the combustion engineering limits”.

Type 2: correction acting Correction mode: applied to the load axis
on the load axis This is used if correction is made via a non-linear actuator, e.g. air flap. The
curve's slope is taken into account before calculating the correction. Thus, a
flat curve results in a small correction range, whilst a steep curve results in a
large one.
ATTENTION:
This is only meaningful if the curve rises monotonically.
