Firing up
Description
Ignition test time
Time for checking if furnace is hot. Only fan is operating.
Fuel dose
Fuel dose during firing up. Concerns first testing firing up. Next
tests fuel dose is reduced(20% of basic dose)
Flame detection
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.
Firing-up airflow
% of blowing when firing up. Too big value prolongs the firing
up proces or causes failed attempt of firing up.
Firing-up time
Time of following firing up attempts (3 attempts). After that
time the controller goes to another firing up attempt.
Blowing after firing up
% of fan blowing after flame detection.
Blowing p. after inflame
Fan operation time with power
Blowing after firing up.
Igniter period
Igniter warming up time before engaging the 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 minimal power
Burner operation time with minimum power 30% after firing
up. Power is determined by parameter:
Blowing power 30%
and
feeder operation time 30%
, in menu: boiler settings –
output modulation.
Operation
Thermostat mode
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 28-29. Boiler temperature
sensor does not influence feeder operation.
Cycle time OPERATION
Time of whole fuel feeding cycle in OPERATION mode.
OPERATION mode time
= feeding time OPERATION
+ feeder
pause time.
Fuel calorific
Fuel calorific in kWh/kg.
Capacity of tank
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.
Extending time of feeder 2
work
Extension of the burner feeder operation time for the time of
the feeder of the fuel hopper.
Burning off
Maximum time of burning off
After this time the controller goes to PAUSE mode, in spite of
the fact that the controller detects flame.
Minimum time of burning off
Burning off will last at least this time in spite of the fact that
flame sensor indicated lack of flame.
Air flush intensity
Fan power during blowing while burning off in %.
Blowing time
Duration of blowing when burning off fuel and burning off.
Blowing pause
Break between airflows while burning off the fuel in burning off
process.
Blowing start
Flame brightness with which airflow starts while burning off the
fuel.
