Num Puls per R
Three pulses per round. Do not change the setting manually!
Standardization Automatic fan maximum rotation speed test. Burner control should be in
standby position when the test begins. Select

from the menu to
start the test.
1. Servomotor for air drives to pre-purge position.
2. Fan motor starts.
3. Burner control steers frequency converter setting to 95 %.
When the fan reaches stable rotation speed, its value is set as
StandardizedSp
value in the menu. This value is equal to 100 % of fan
rotation speed, 5 % is reserved for possible environmental condition change.
StandardizedSp
Do not change the setting manually! Perform standardization as described
above.
SettlingTime
Rotation speed measured by frequency converter control. At stable output,
the frequency measurement result stays almost the same. If the result varies
notably, check the sensor operation.
Setpoint Output
Frequency converter control value can be set to 0…20 mA or 4…20 mA.
If automatic speed standardization is activated or standardized speed is
changed manually, burner must be readjusted.

module (WD200)
O
2
module, connected to burner control through CAN bus, can be connected with
oxygen sensor.
When control voltage is switched on, and oxygen sensor is activated, heating is on and
oxygen sensor is ready for operation.
Activate oxygen sensor during first start-up, and always after power failure, to start
heating. Oxygen sensor is ready for operation when 700 °C / 1292 °F is reached. It
takes approx. 10 min to reach the temperature.
Oxygen sensor is self testing. Self test monitors aging of the device, based on
measurement cell resistance and response time. If measurement cell resistance and
response time exceed 400Ω and 25 seconds, self test gives an alarm, and sensor must
be changed.
