This menu enables the installer to manually change the output by using incrementing or
decrementing commands, letting the actuators operate on interpolated straight lines
(outside the parameterized curvepoints: Extrapolation). Above that, the currently ac-
quired O2 value will now be shown if a PLL52.110A200 O2 module and an O2 sensor
are connected to the system.
Traveling to the output preset here can be stopped by pressing Esc .
The actual curve settings are made by adjusting the entire ratio control system based on
the roughly predefined curvepoints and outside the already defined points. After press-
ing Enter again, new points can be introduced at the required positions.
Then, the values can be changed:

Example: Adjustment of the ratio control system via manual control
Prerequisite: No curvepoints are parameterized.
1. Activating program stop
On menu: «Params & Display» → «Ratio Control» → «Program Stop»
→ parameterize from «deactivated» to «Stop_Ph24»
2. Starting the system
On menu: «Params &. Display» → «Ratio Control» → «Settings Gas / Oil» → «Special
Positions» → «Autom / Manual / Off»
or on:
«Manual Operation»
and confirm.
3. Setting the prepurge positions
The system commences the startup sequence and stops in phase «Driving to Prepurge
24». Now, the prepurge positions can be set on menu «SpecialPositions». Then, on
«ProgramStop», change to «Stop_Ph36.
4. Setting the ignition positions
The system continues the startup sequence and stops in phase «Driving to ignition posi-
tion 36». Now, the ignition positions can be set on menu «SpecialPositions».
Then, on «ProgramStop», set to «Stop_Ph72», if operation shall immediately follow.
To readjust the ignition positions after the burner has ignited: «ProgramStop» to
«Stop_Ph44», or «Stop_Ph52» for pilot ignition after the pilot flame has been shut
down. Then, on «ProgramStop», set to «Stop_Ph72».
