9. Delete intermediate load points
Delete all load points except for point 1 and full load (Load: 100).
When an intermediate load point is deleted, all points above this intermediate load
point are reduced by one number.
10. Set new intermediate load points
Starting at point 1, set new load points until full load is achieved.
A maximum of 15 load points can be programmed.
A minimum of 5 load points are required for modulating operation.
Only in conjunction with frequency converter
To ensure an even speed characteristic curve, the speed of the new load points
should not be altered.
Increase burner rating in menu Manual, whilst observing combustion values.
Set new intermediate load point using [ENTER] key.
Optimise combustion at intermediate load point via air damper setting (Air).
If the burner is equipped with an adjustable mixing head, the combustion can be
optimised by utilising the interaction between air damper (Air) and Mixing head
(Aux1).
Carry out load apportionment [ch. 7.11].
Repeat steps until full load (Load: 100) has been reached.
Exit level using the [esc] key.
11. Check start behaviour
Switch off and restart burner.
Check start behaviour and if necessary correct ignition position.
If the ignition position has been altered:
Re-check start behaviour.
12. Define partial load
Select LoadLimits.
Select MinLoad.
Define and set partial load whilst:
observing data provided by boiler manufacturer,
Maintain return pressure:
Fuel oil EL: min 8 bar
Heavy oil: min 12 bar
observing the burner capacity graph.
