7 Instructions on Commissioning and Maintenance
7.4 Commissioning Flow Chart
Simple and fast process for commissioning the F200K.
NOTICE
The following steps require that all work in the previously described chapters on installation
and mounting has been carried out correctly and checked again.
The frequency DIP switches (1) are required for existing background radiation with
low frequencies. The low frequencies (below 10/20/30Hz) are faded out depending on the
setting.
NOTICE
The frequency DIP switches (1) A and B must always be adjusted together. (two-channel
system), only one frequency range may be selected, the other two must be set to "Off".
The Serv. switch is issued to suppress the indication during start-up and starting time
of the flame detector. The flame detector is supplied with the Serv. switch in the ON position
as default. For commissioning it is recommendable to set the Serv. switch to OFF.
The Adj switch is for commissioning. In the "ON" position, the sensor signal is displayed with
the intensity display (3) in the range 0... 150 mV
The start-up suppression function (4) (rotary potentiometer 0 ... 100%) allows suppression
short pulse rates, which may occur on burner start in connection with the fan operation
(pre-ventilation) and background fire.
See Chapter
7.2.4.5 Start-up Suppression
1 Set all frequency DIP switches (1) to default as
shown in the drawing.
2 Set rotary switch (8) to position 6.
3 Connect the multimeter to the measuring points
(9) and (6) (the multimeter setting is "AC volt-
age"), for good flame detection a minimum
voltage of
≥
50 mV AC* required.
4 Start the burner in the lowest load.
5 If the voltage is higher than 100 mV, the rotary
switch (8) must be reduced step by step.
6 If the voltage is less than 50 mV, it is necessary to
switch to range II (switchover by connecting the
yellow and red wires of the connecting cable)
then increase the settings of the rotary switch (7),
(Default is 11, start with 8 here).
