6.9.4 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-purge, the burner's output is increased or de-
creased until the actuator can be driven all the way.
6.9.5 Checking the Combustion Limit 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 mon-
itor the combustion boundary values.
NOTICE
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.
