O2- regulation

Air shortage
perturbation
If the actual O
2
value is significantly smaller than the target value and corrective action by the
FMS/VMS cannot rectify this error, the regulator is deactivated and the base value for air
shortage errors is output. If desired, an air shortage burner shut-down can be triggered by the
FMS/VMS. This is achieved by setting parameter 897 to 1.
The error code is H360, "Error shut-down by O
2
regulator”.
Resetting O2-errors O
2
errors are automatically reset with each new burner start-up. This is permissible, since 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:
Set selector switch (1) to Status
-FMS in O
2
regulation mode?

regulation mode by pushing channel key 3 (4) upwards
Press the "Enter" key (3) and
-call up the cause of error (mandatory!)
Push key 3 (4) upwards
Calling up O2-
regulation fault
history
Switch over to FMS/VMS mode (compound regulator)
Selector switch (1) to Status
Switch channel 3 down
- In this way the fault history can be browsed through by actuating the switch channel 2
In the event of perturbations, a warning message is displayed and the O
2
regulator is deactivated. The specified base value "Without regulation” or
the one for "Air shortage” is set.
The display shows the running text "O
2
regulation perturbed”.
The burner is not shut down as a rule.
The corresponding error code can be called up by setting the selector
switch to Status. A plain text message about the cause of error appears
after pressing the "Enter" key (3).
