14 Description of service parameters
14.1 Burner
Time to check whether the burner is already firing up. Only fan is operating. If the
flame has sufficient brightness, it switches to the OERATION mode without the
BURNING OFF mode.
Fuel dose during firing up. Concerns first testing firing up. Next tests fuel dose is
reduced.
Threshold of flame detection in % of light, when the controller deems the furnace as
hot. It is also used for detection of lack of fuel and end of burning off.
% of airflow when firing up. Too big value prolongs the firing up process or causes
failed attempt of firing up.
The time of a single fire-up attempt. After this time the controller goes to the next
ignition attempt. After unsuccessful attempts of ignition, an alarm is given Failed firing
up attempt.
• Blowing after firing up
% of blowing fan after flame detection.
Igniter warming up time before engaging the blow fan. It should not be too long as to
not damage the heater. After this time the heater works still until detecting the flame.
• Worktime with min. power
Burner operation time with minimum power after firing up. Power is determined by
parameter Min blow-in output.
Pulsation of the blowing fan in Firing up.
Switches the burner into thermostat mode, i.e. for working in bakery. The burner
operates with maximum power without modulation of power. The burner deactivates
with disconnecting thermostat joints. Boiler temperature sensor does not influence
feeder operation.
Time of whole fuel feeding cycle in OPERATION mode, where: Cycle time OPERAT. =
feeding time + feeder pause time in OPERATION mode. The work of the burner feeder
is always extended compared to the work of the main fuel feeder.
Fuel calorific in kWh/kg.
Fuel silo capacity for counting fuel level. When correct amount is put, the user is not
obliged to calibrate fuel level. The controller process this data if calibration process of
fuel level was not done. After successful calibration of fuel level the controller does not
process this value.
After this time the controller goes to STOP mode, in spite of the fact that the controller
detects flame.
Burning off will last at least this time in spite of the fact that flame sensor indicated lack
of flame.
Blow fan power during blowing while burning off.
Duration of blowing when burning off fuel and burning off.
Break between airflows while burning off the fuel in burning off process.
Flame brightness with which airflow starts while burning off the fuel.
Flame brightness with which airflow starts when burning off the fuel in burning off
process.
Fan operation time during cleaning the furnace while firing up.
Fan operation time during furnace burning off.
Blowing fan power during furnace cleaning in burning off and firing up.
Time work rotary output during cleaning the burner and the time break of rotary cycle
during cleaning the burner.
It is the maximum time of the controller residence in the SUPERVISION mode. After
this time, when the controller is in SUPERVISION mode, the controller automatically
starts burner burning off. By settings Supervision time= 0, the SUPERVISION mode is
deactivated. By settings Supervision time= 255, the SUPERVISION mode is not
deactivated.
Boiler power in Supervision mode.
Feeder operation time in SUPERVISION mode, where: Cycle time = feeding time +
feeder pause in Supervision mode.
Blowing fan power during operation in Supervision mode. Adjust value in such a way to
burn feeding fuel in Supervision mode with low fumes emission.
In this mode automatic fuel feeding is off.
The duration of the fan blow in the supervision in grate mode. The value should not be
too high so as not to cause excessive water heating in the boiler.
