6.1 What happens if a fault occurs in the O
2
regulation
In the event of malfunction, the display shows a warning and the O
2
control is deactivated.
The specified base value "without control” or the one for "air deficiency” is set. The display
shows the running text "O
2
regulation perturbed”.
The burner doesn’t shut down.
Set the selector switch to "Status" to call up the corresponding error code.
6.1.1 How to switch the Display
WARNING!
You can set the O
2
trim only, if you have completed the programming of the compound.
6.2 Air Deficiency Pertubation
If the O
2
actual value is significantly smaller than the O
2
setpoint value (below the second
monitoring band) and corrective actions by the ETAMATIC cannot clear this error, the regula-
tion will be deactivated and the base value for air deficiency errors will be output. If desired,
the ETAMATIC triggers an air deficiency burner shut-down. Therefor set parameter 897 to 1.
The error code is H360, "Error shut-down by O
2
regulator”.
6.3 Resetting O
2
-errors
Each new burner start-up resets O
2
errors automatically. This is permissible, because a 100%
O
2
measurement test is performed at each start-up.
Manual resetting of O
2
errors is possible at any time, as follows:
Press key 11 ENTER

The display shows a plain text message about the cause of
the error.
Press key 15 to change the display from status of the compound to O
2
value (if active)
and to flame intensity (if active). If neither O
2
trim, nor integrated flame scanner is
active, key 15 has no function.
Press key RESET
