is not available for regulators, which are
provided with STANDARD mode of operation
only.
In Standard mode the regulator operates in
automatic cycle with parameters preset by
the user. The preset values are available in:
MENU Boiler Settings Burner
Settings .
The fan works continuously with constant
blow-in output preset in the parameter
Blow-
in Output . The feeder starts periodically and
remains in operation for the duration set in
Feeding Time, then it stops and remains off
over the time set in Feeder Interval .
Cycles of Blow-In and Feeder operation in
OPERATION mode; A
– Feeder Interval, B –
Feeding Time.
These parameters should be properly
selected subject to boiler output, and fuel
type and quality. Usually, they are factory
set by the boiler manufacturer.
As the factory settings do not
always comply with the given
boiler type, they should be
adapted to the given boiler and
fuel type.
Burner adjustment instruction:
- set the parameters:
Feeding Time and
Feeder Interval so that the required boiler
output (e.g. 15kW) has been reached. Boiler
power is displayed in MENU
→
Information ,
- select the proper blow-in output to the set
fuel stream.
Note: boiler power will be properly displayed
provided that the values of service
parameters:
Feeder Efficiency and Energy
Density have been properly entered!
Feeding Time- OPERAT and
Feeder Interval- OPERAT should
be so selected that the furnace
does not retrace to the fuel
feeder.
Once the preset boiler temperature has been
achieved, the regulator automatically enters
SUPERVISION mode.
7.7 OPERATION – Fuzzy Logic mode
Upon change of boiler regulation mode from
Standard to Fuzzy Logic, regulator works in
OPERATION mode and modulates the boiler
output to achieve constant preset boiler
temperature.
Fuzzy logic regulation mode may be set in:
MENU Boiler Settings Burner
Settings Regulation Mode
Please note that Fuzzy Logic program is
adapted individually to the given boiler and
fuel type and may work properly only with
this boiler and fuel. Therefore, the
Fuzzy
Logic mode requires special settings and has
to be activated by the boiler manufacturer in
accordance with sec. 21.1. In case this mode
has not been activated, it will not be
available.
Fuzzy Logic correction
In some instances, Fuzzy Logic mode has to
be adjusted to the fuel quality. To make the
correction, use the following parameters:
FL
fuel correction and FL airfl. correction which
are available in:
MENU Boiler Settings Burner
Settings .
At first adjust the FL fuel correction. If fuel is
of poor quality and incompletely burnt fuel
particles are present in ash, reduce the rate
of supplied fuel; in the contrary case -
proceed in analogical manner.
Note: incompletely burnt fuel particles or
lowered furnace may be also caused by
improper boiler operation in SUPERVISION
mode. Therefore, prior to correcting
Fuzzy
logic it is recommended to adjust parameters
of SUPERVISION mode in accordance with
sec.7.8.
Activation of the Fuzzy Logic
mode does not release from the
requirement
to adjust the
parameters of SUPERVISION
mode – risk of screw feeder
damage.
