FMS Fault Correction
Parameters ( P )
Aids
P18
This parameter is used to configure the burner for post-ventilation.
Parameter 758
If the time is set to "0”, no post-ventilation occurs.

P19
This serves for entering how many seconds the ignition position relays are
Parameter 755
delayed after detection of the ignition position by the compound (or ignition on
the FMS is released).
_____________________________________________________________________________________________________
P20
Here a delay time may be set so that the compound waits before leaving the
Parameter 756
programmed, separate ignition point after ignition, to run to the next base load
point.
This parameter only has any effect if a separate ignition point is configured.
_____________________________________________________________________________________________________
P21
This serves for setting the delay time during which a given control release
Parameter 757
(signal on terminal 4) is ignored. During this time the burner remains in the
ignition position or base load.

Correction input spread factor
This can be used to set a situation where the correction has a smaller effect at
weak loads or vice versa, in the range (00.0 - 99.9).
The standard setting is 10 (i.e. 01.0), then the correction has the same effect in
all load ranges.
With values above 1.0, the selected correction range increases with rising load
and reaches the times-X value at full load.
Example:
Parameter value 35
^
(3.5)
Correction range 150 points
With weak load the correction range is 150 points and at full load - 525 points.
There is linear interpolation between these values.
With values below 1.0, the selected correction range drops with increasing load.
Example:
Parameter value 5
^
(0.5)
Correction range 200 points
With weak load the correction range is 200 points and at full load - 100 points.
P23
These are used to set the baud rate of the serial interface. The standard value
Parameters 822, 823
for the parameter content is "4” (19.200 baud). Should it be apparent from the
system that problems are occurring with serial transmission (particularly with
long serial connections), it may possibly help to reduce the baud rate.
However, this must be done both on the FMS and on the operating unit,
e.g. laptop.

Parameters 433, 434
___________________________________________________________________
This can be used to increase or reduce previous weighting of the
correction range via the correction mode on the load axis.
