CAUTION! In case emergency input is not used, „NO” parameter shall be selected
in „Auger ignition test” setting and contacts of „X” input shall be closed.
Auger ignition temperature - this parameter specifies auger temperature, when the
controller activates auger ignition alarm. This parameter is unavailable when „NO”
was selected in „Auger ignition test” setting.

Flame detector - flame detection may follow with two methods: burner temperature
measurement or brightness measurement. In case when temperature sensor is
used, depending on its location, temperature measurement range may be from
several degrees to several hundred degrees. If measured temperatures do not
exceed 100°C it is recommended to use CT-1 or CT-2 sensor. In case of higher
temperatures, PT-1000 sensor shall be used. For flame brightness measurement,
FD-1 optical detector shall be used.

Correction of the photodetector indications – the parameter is available only
when an optical flame detector (FD-1) has been selected. It determines the quantity
of light „seen” by the sensor after the burner has been extinguished. The value of
correction is deducted from the measured quantity of light during the flame detection
stage. The correction enables the user to calibrate the FD-1 sensor so that the result
of illuminance measurement while the burner is extinguished could equal „0”.

Hysteresis loss of flame - depending on the type of flame detector, this parameter
specifies how many degrees or units in relation to the threshold set by the user must
cut off the lighter or the brightness of the flame temperature to the controller began
to flame failure detection procedure.

WARNING! If the hysteresis is larger than the threshold of igniter shut down, flame
failure detection procedure is started when the temperature drops or the brightness
of the flame to the value of „0”.
