Adjusting load ratings individually - when load points are to be adjusted without programming
a complete curve
___________________________________________________________________
When adjusting individual points it is normally only possible to freely adjust the
set-point values. This is done by running to the load value (figure appears after
the value). The associated set-point can be adjusted. The figure, which shows
that the change is admissible, appears not only right at the programmed load
point but also in the range ± 3 points around this. When stored, however, the
value actually displayed is adopted.
At each adjustment of individual points it is therefore possible to shift the load
value by up to 6 points.
___________________________________________________________________
Procedure for shifting the load value:
Undertake operations as described under "Adjusting individual points”
but shift the load rating as required,
Set set-point value
Store
If the desired load rating cannot be achieved in one operation:
Repeat procedure
-
Output point is now the last curve entered
Entering an initial curve
Since, prior to initial programming, the set-point EEPROM contains a
standard curve that very probably doe not correspond to the actual
conditions of the system (ranges, set-point values), the following
procedure is recommended for the initial curve:
Make sure that the signal wiring is correct
- see Function test and Manual
Clear memory
Leave FMS at "Setting”
Have system started up without control release (terminal 4)
After pre-ventilation, enter ignition load point
Ignition
Give control release (terminal 4)
Enter further points with burner running
Store
