automatically to obtain the set value of
oxygen concentration in exhaust. If this
parameter is set at Off - lambda sensor
indications will have no effect on regulator
operation.

Description of other parameters related to
lambda sensor:
Airflow correction range - determines
permitted range of blowing power variation
for operation with lambda sensor. Note: do
not set too high values because it may
adversely affect regulation process.
Fuel detection-oxygen - this parameter
enables detection of fuel lack on the basis of
Lambda sensor indications. If the oxygen
level has been in excess of Fuel lack
detection threshold - oxygen longer than the
time set in No fuel detection time - regulator
attempts again to fire- up the furnace, and if
unsuccessfully - lack of fuel alarm will be
produced.
Feeder lock – this parameter determines the
oxygen concentration in exhaust below which
the feeder operation will be stopped until
another increase of this value.
After longer period of sensor operation, its
periodic calibration may be required. Before
calibration, the boiler has to be burnt-off.
Proper calibration requires complete burning
off the boiler furnace. To start calibration,
use the following parameter:

Lambda calibration
Calibration takes approx. 8 min.
