6.11.5 Calling up the Set Correction Mode
Take the correction into account during later programming.
The correction actuator must be able to operate without the ETAMATIC reaching the end-stop
(0 or 999 or limit stop values).
If the correction actuator cannot be driven all the way as required because a channel has
reached the range limit determined during pre-ventilation, the burner's output is increased or
decreased until the actuator can be driven all the way.
6.11.6 Checking the Combustion Boundary Values
It is necessary to guarantee the combustion facility's safe burning even with the maximum cor-
rection applied. The correction value can be modified as follows in order to set the correction
range and monitor the combustion boundary values.
Adjustment of the correction range is possible in parameter 517. If you adjust parameter 517
while the burner is running, adjust in small steps and pause between two steps. Otherwise the
fault 106 may occur.
NOTICE!
The burner must be ON and the control release must be set.
Example: 20 - 100 is a typical correction range for O
2
trim.

This means: With a correction mode from +60% to -40% (factory set-
ting), the control range, which is adjustable via the correction during
correcting to se120; -80...+60; -40; (in digit)
Recommendation: You should chose the correction mode and the correction range in
that way, that the correction effect on the O
2
value is -2 to 3 vol.% O
2
in direction excess air, and 1 to 1.5 vol.% O
2
in direction air deficiency.
