5.4 Operation of converter 5012
The converter box 5012 is specially designed and
adapted for the connection of the compact flame control-
ler type CFC 3000. This converter box will expand the va-
riety of functions of the CFC series and to use them in the
maximum range.
At first they can be used as a power supply which is spe-
cially designed for the compact flame controllers. With its
wide range input of 100 – 240 V AC it is very easy to use.
For higher loads on the flame relay the converter boxes
are including a secondary relay which is controlled by the
internal flame relay of the CFC but which is designed for
up to 250V AC and 1A.
The main application of the 5012 is the additional current
output of 0(4) – 20mA generated by the main flame flicker
frequency and which is in parallel to the original current
output of the CFC.
The main flame frequency is evaluated by a special algo-
rithm and will be transmitted as a serial RS 232 signal to
the converter box 5012 (data transmission is indicated by
the flashing green LED 4). The 100% value of the fre-
quency current output can be changed in 16 steps at the
rotary switch 2. The start value of 0 or 4mA can be se-
lected with a DIP switch on the front plate.
By using the USB connector on the front plate all data can
be visualized at a connected computer. This function is
restricted to read only.
It is possible to connect up to 64 x 5012 and therefore
CFC 3000 together in one loop. By using a special visuali-
zation software all 64 CFC can be monitored in parallel. It
is also possible to get more detailed information by using
the multi window function with four different windows or as
known from the CFC 2000 window as a single screen for
each separate CFC 3000.
Each box and therefore burner will be addressed by itself
individually with the rotary switch and two DIP switches so
that every CFC can be displayed at every time. Further-
more it is not necessary to do any additional changes in-
side the CFC if it has to be changed.
