Parameter Meaning
StopSwi Select end switch to be measured
The RVW26... automatically measures at what feedback potentiometer value the
end switches have reached their «Fully open» and «Fully closed» position.
This value is checked each time the burner is started up.
The measured value of the end switches is stored as soon as the feedback signal
does not change anymore.
If 2 fuel actuators are used, the measurement must be made with both types of
fuel.
The end switch values currently stored can be displayed by pressing «+» and «-».
If «D» or «Ñ» is pressed, the status character changes from «^» to «#».
The selected end switch positions «Open» or «Close» will be approached and
stored.
Once the values are stored, the status character changes to «>».
The other end switch position can now be measured by pressing «+» or «-».
