After a pre-amplification, the unwanted CW light component is withdrawn from the output signal of the wear-resistant detector. The subsequent sensitiveness attitude allows an attenuation of the signal for adaptation to the combustion proc-ess. The post-connected band pass filter caused, that only the typical modulation of the flame ra-diation of the primary combustion zone is valued and so extraneous light signals by neighbour burners can be distinguished from the own flame. Further functional groups include signal condi-tioning and other for the so-called dynamic moni-toring channel which checks the fail safe function of the device continuously. A component or component defect leads to an immediate disconnection of the flame relay, which one is available as a floating change-over contact for use with the burner management sys-tem. The switching condition is announced addition-ally by a yellow LED on the reverse side of the device behind the Perspex pane. For the optimal adjustment of the compact flame controller the flame strength can be read off di-rectly on the device by means of a pulsating green LED. For the visualization or remote indi-cation, a current output is available at 0 or 4-20 mA. The safety switched-off time which depends on the combustibles to be checked is set ex-works to a second. Longer switched-off times are op-tionally available upon request. 3 WARNING WARNING: The functioning of the compact flame controller depends both on the burner configuration and from the air flow as well as the spectral pattern of the flames (wavelength). We will advise you gladly in this regard on request. Selection of the current output 0 or 4 to 20mA The switch over of the current output of the compact flame controller CFC 1000 / 2000 will be carried out by the special software which is available from BFI Automation. Selection of the right modulation filter For furnaces with very high power density, it can become necessary to activate another modulation filter besides. The compact flame controller should not be ad-justed to maximum signal level "Flame ON" but as with the flame scanners also, to the highest "Flame ON" / "Flame OFF" relation. Through the numerous adjusting options of the compact flame controller the system itself could be eas-ily adjusted to all boiler geometries and any combustible throughput for getting an optimal availability. The adjustment of the modulation filter occurs via DIP switches which are arranged on the main board (red 4-part switches). A change of adjustment to the DIP switches should only oc-cur if an adjustment of the compact flame con-troller is no more possible with the aid of soft-ware. Mounting For guarantee of an optimal flame safeguard control, the correct and oscillation poor posi-tioning of the sight tube to the flame is an es-sential assumption. For the selective burner control, the mounting has to occur in such a way that the primary combustion zone will be in all load ranges at the viewing angle of the device. The prolongation of the viewpoint axis must not cut the first half of other flames. Length and diameter of the viewpoint tube have a direct influence on the valuable flame radia-tion since the viewing angle of the compact flame controller CFC 2000 is defined. The maximum length of the used sight tube should not exceed the maximum length 'L' on a given diameter 'd' that no influence on the field of view will occur. d 1" 1,5" 2" L 0,5m 0,8m 1,1m However the sight tube should always be kept as short as possible. A diameter of 2"is rec-ommended. The correct direction is repre-sented in the subsequent drawing. The optical alignment system BFI 235 (part-no: P106) can be supplied by BFI ex stock. The compact flame controller CFC 1000 / 2000 is supplied completely with a quick release flange. This flange assures possible assembly and dismantling of the device on site which could be done as quickly as possible. The flange has a purge air connection which spe-cial construction prevents the lens of contami-nation or damaging by dust polluted air. The optimal alignment system consists of heat insulator, stop valve and ball flange. This mechanical periphery can be supplied upon request. 4 CAUTION CAUTION: All alignments and or adjustments must always be applied if new repair parts were installed, the flame scanner was moved or the flame picture was modified (e.g. through additional combustibles, new torches, changes to the torches / air registers), as well as all ini-tial installations.

The output signal 0(4)-20mA for flame intensity is not separated by the supply voltage, so the sig-nal refers to the operating voltage measures. If this should lead to problems, a corresponding isolating transformer can be provided upon re-quest. The burden of 250 ohms should always not be exceeded. The device is immediately ready for operation af-ter switch-on of the supply voltage.

The burner has to be started and stopped several times (the flame relay must always interrupt reliably with no flame on). Carry out these tests while different neighbour burners are started and stopped as well as on different boiler loads. This is a vital assumption for a proper and reliable operation. 6 G1/2108190G 1 235SpülluftAutomationtechnology for your future BFITypeSer.-No.:24VdcGermanyCFC 200088120106152122CF C 2000155G1Fibre optic cableSKLO/E-Converter Standard Housing Suitable for use in hazardous areas Zone 2 II 3 GEx nA II T4 OE-Converter housing Suitable for use in hazardous areas Zone 2 II 3 GEx nA II T4 7 G 1Ø12022363Ø13 232262304142166.5195.523214II 2 G Ex d IIC T6II 2 D Ex tD A21 T80°CExplosion Proof Housing 0032Type 07-6152-9024 II 2 G Ex d IIC T6 II 2 D IP 66 T 80°C For us in hazardous areas classified as Zone 1 PTB 03 ATEX 1051 EXPLOSION PROOF HOUSING FOR OE-CONVERTER For one OE-Converter For us in hazardous areas classified as Zone 1 KEMA 08 ATEX 0123 8 Accessories Power supply 230/115V AC Ball flange 1” with 2” flange plate Heating insulator 1“ 3-way-ball-valve 1“ 5bar pressure barrier 1“ Optical adjustment device Accessories for OE-Converter Probe SKL for IR or UV Fibre optic cable Y-fibre optic cable Fibre optic lance Technical Data Sheet Spectral Sensitivity UV 270 to 420 nm UV1 190 to 500 nm IR 300 to 1050 nm IR1 1050 to 2700 nm IR2 300 to 2700 nm Viewing angle 2,7° Power supply 24 V DC Current consumption approx. 100 mA, for triple Ex-OE-Converter approx. 300 mA Construction protection class III SELV Ambient temperature range -20°C...+60°C Current output 0(4)...20 mA (Ra < 250 Ohm) Current window possible adjustment by software Failure output 24 V DC, short circuit protected Application programming interface IRDA/RS232 (IRDA/USB in preparation) Sensitivity switch over Selection of the sensitivity switch over 24 V DC Flame relay 1 change over contact, floating VDE 0110, class A max. 48 V switching voltage max. 1 A switching current max. 30 W switching power Switching thresholds programmable by software Safety switch off time factory adjusted to 1s Sight tube connection 1" inside screw ISO 228 Purge air connection 1/2" inside screw ISO 228 Value of purge air 10 Nm3/h 9 0032Type 07-6152-9024 II 2 G Ex d IIC T6 II 2 D IP 66 T 80°CII 2 G Ex d IIC T6II 2 D Ex tD A21 T80°C Electrical connection Standard Harting connector HAN8 90 degrees Explosion proof housing 3m special cable OE-Converter housing Harting connector HAN8 90 degrees Ex-OE-Converter housing M20-screw joint and terminal clamps inside Dimension Standard with flange 235 x 108 mm (Length x Diameter) Flame proof housing 223 x 120 mm (Length x Diameter)* OE-Converter housing 120 x 122 x80 mm (Length x Width x Height)* Triple Ex-OE-Converter 276 x 276 x 166.5 mm (Length x Width x Height)* *without connectors and mounting bracket Class of protection Standard housing and OE-Converter housing IP 65, similar to NEMA 4/Class 1 Div 2 ATEX Zone 2 II 3 GEx nA II T4 Ex- housing IP 66, similar to NEMA 4/Class 1 Div 1 ATEX Zone 1 PTB 03 ATEX 1051 Ex-OE-Converter housing ATEX Zone 1 KEMA 08 ATEX 0123 Weight Standard 1.5 kg Flame proof housing 4.0 kg OE-Converter housing 1.5 kg Ex-OE-Converter housing 7.0 kg Triple Ex-OE-Converter 13.0 kg Full electronically self-check function for the guarantee of the faultless function of the device after VDE 0116, EN 230, EN 298, it correspond the guidelines TRD 411 to 414.
