KG Safeguard F150 / FFS 05 ... or FFS 06 … Page no.: 3 0 Scope This description provides instructions on the use of the F 150 Flame Safeguard. 1 Purpose The F 150 Flame Safeguard is a safety device, and complies with the DIN EN 298 and DIN EN 230 standards. The purpose of the flame safeguard is to detect the burner flame of a furnace uninflu- enced by the conditions prevailing in the combustion chamber (such as glowing of lin- ing), and to trigger off, in case of flame rupture, a control command to cut off fuel sup- ply. This device is chiefly used in furnaces, where there are no complicated selection tasks required, e.g. in power stations, heating stations, chemical plants and wood burning plants operated from oil, gas, dust coal or mixture burners. The functioning of the F 150 Flame Safeguard is characterized by a high degree of safety, availability and ease of servicing, what is due to - a digital signal processing, - a dynamic self-check system - an appropriate number of checking and operational controls. The flame safeguard output provides a safe floating switch-over contact. 2 Technical parameters 2.1 Parameters Input values - Flame sensors Required input values produced by the flame radiation to deliver the message: ”Flame in” - spectral radiation range = 260 ... 400 nm (FFS 05 UV1, FFS 05 UV1 Ex, FFS 05 UV-1 Ex II, FFS 06 UV-1) - spectral radiation range = 210 ... 380 nm (FFS 05 UV2, FFS 05 UV2 Ex, FFS 05 UV-1 Ex II, FFS 06 UV-2) - spectral radiation range = 850 ... 1200 nm (FFS 05-1, FFS 05-1 Ex, FFS 05-1 Ex II) - spectral radiation range = 1200 ... 2800 nm (FFS 05, FFS 05 Ex, FFS 05 Ex II, FFS 06) - Pulsation frequency ok. 10...90 Hz

The output levels are continuously checked for antivalence. Parameter adaptation, Furnace --> Monitoring device A switch located inside the F 150 allows to set four different degrees of intensity. The flame intensity is displayed by means of the green two-stage luminescence display. The transmission range of the digital frequency evaluation allows for a signal passage of 10 and/or 30 Hz to 90 Hz. Signals with a frequency between 45 ... 55 Hz (with a nominal frequency of 50 Hz) are not transmitted.
  5. 5. LAMTEC Leipzig Technical Discription of the Flame Edition: 01/07 GmbH & Co. KG Safeguard F150 / FFS 05 ... or FFS 06 … Page no.: 5 3 Structure The Flame Safeguard consists of: a flame sensor of the FFS 05 ... or FFS 06 … type, which can be fixed optionally by us- ing one of the FS19, FS 20, FS 36, FS 41 for FFS 05 … or FS 60 for FFS 06 … adjust- able holdung devices, and a flame monitoring device of the F 150 type, which com- prises the following functional units: - digital frequency evaluation unit - self-check unit - switching amplifier - power supply unit. FFS 05 ... Flame sensor The component parts of the sensor circuitry are located on PCBs housed in a cylindrical casing, which is provided with an axial light incidence opening proof against water jets. The flame sensor satisfies the requirements of the IP 65 enclosure type. FFS 06 … Flame sensor The components of the sensor circuit are accommodated on circuit boards in a cylindri- cal casing with radial splash-water proof light inlet opening. The flame sensor meets the requirements of protective type IP 65. F 150 Flame monitoring device The component parts of the functional units are located on a PCB. Its constructional design is suitable for either the use of 19 inch sub-rack system and for such sub- assemblies that allow allocation of 19 inch components (such as Murr Electronics). The checking and operational controls are located on the front panel. The connection of the device is made on the rear side using a plug strip of the D design (see pin configura- tion). The arrangement of the checking and operational controls is illustrated in section 10. 4 Mode of operation (see section 9, basic wiring diagram) FFS 05 ... or FFS 06 Flame sensor The Flame sensor converts the pulsating burner flame radiation into electrical signals. The resulting representation signals are routed to an electronic switch-over contact, which alternately puts the signals through to the two separately working processing channels. These processing channels digitize the signals, this resulting in a conversion of the original signal type into the evaluation criterion ”Pulse length” (information carrier: flame radiation frequency). The F 150 Flame monitoring device is mounted at a distance of the the flame sensor. The connection to the flame monitoring device is made using a five-pole, statically shielded cable.
  6. 6. LAMTEC Leipzig Technical Discription of the Flame Edition: 01/07 GmbH & Co. KG Safeguard F150 / FFS 05 ... or FFS 06 … Page no.: 6 F 150 Flame monitoring device The F 150 comprises two separately working signal processing channels. The flame signals transmitted by the sensor are regenerated by the input stage of the F 150 and compared with the related reference signals, only those flame signals being processed that are within the preselected transmission range irrespective of their origi- nal amplitude. Signal transmission is effected via two separately working transmission channels. If required, the lower frequency limit can be modified between 10 Hz and 30 Hz using a switch located under the cover hood, this to be done when the F 150 is dis- connected from power. Moreover, it is possible to adapt the device to the flame intensity using a four-position selector switch for intensity remote switching-over. The selection is displayed by a two- stage luminescence row. Before switching on the output relays at the end of each signal processing channel, a safe monitoring of the antivalent switching states, as well as of the response and switch- off delay is effected at the output of the signal processing channels. Any off-limit antiva- lence faults or deviations in time delays result in an immediate switch-off (switching state ”flame out”). The switching states of the signal processing channels and the output relays are dis- played by a red and a green light emitting diode located at the front panel. There are moreover the following connections: - Auxiliary power feed - Connection of the system earth in conformity with DIN VDE 0100, part 540 - Flame sensor connection - Connection of external power circuits to a safe switch-over contact to enable the ”Flame in” and ”Flame out” switching states. 5 Operating conditions Auxiliary power, input + 10% Mains voltage 230 V A.C. - 15% Mains frequency 50 Hz Power consumption abt. 6 VA

The flame sensor should be aligned in such a way - as to cover the first third of the flame in single monitoring operation - as to cover the root of the flame in the ”Flame in” state (area of high flame frequencies) only the residual radiation in the ”Flame out” state that is emitted by the marginal sec- tions of the other burner flames (area of low flame frequencies) and/or by the reflected radiation. Proper arrangement of the flame sensor is therefore a decisive precondition for a high availability and/or the possible degree of selection.
  9. 9. LAMTEC Leipzig Technical Discription of the Flame Edition: 01/07 GmbH & Co. KG Safeguard F150 / FFS 05 ... or FFS 06 … Page no.: 9 WARNING ! The sensor cable must be routed separately from mains and control cables, as well as power cables or power equipment (such as ignition lines, ignition transformer, electrical motors, contactors). Cable routing parallel to mains cables in the same cable duct is not allowed. 6.1.2 FFS 05 and FFS 06 Flame Sensor Dimensions see dimensioned drawing, item 11.2 and 11.3 Weight abt. 0.4 kgs Cable type FFS 05 stranded hook-up wire LiYCY (blue, red, green, yellow, white) 5 x 1 x 0.5 mm² (AWG 20) Cable type FFS 06 stranded hook-up wire LiYCY (blue, red, green, yellow, white, pink) 6 x 1 x 0.5 mm² (AWG 20) The Flame sensor is supplied with a connection cable. The feed cable can be extended up to 500 m between flame sensor and flame monitoring device. For an extension to be installed on site, we recommend to use a separate, shielded five-core extension cable, which can be connected with the sensor feed cable using the FG 21 junction box. Connect the sensor casing to the system earth by means of the casing screw marked with the earthing sign. The cable shielding must not be used as low frequency carrying system earth connec- tion. Install an earth compensating line between the sensor casing connection and the flame monitoring device connection to system earths separated from each other by the related distance. Mount the Flame sensor to the socket piece of the scanning opening, through which the burner flame must be properly visible throughout the furnace operating range. For a se- lective monitoring, locate the scanning opening in such a way that the flame sensor covers the root of the flame to be monitored (near the burner nozzle). Note that the longer the socket piece is the more the range covered by the flame sensor is limited. The scanning opening must be sealed by an appropriate protective glass. 6.1.3. The F 150 Flame monitoring device Dimensions see dimensioned drawing, item 11.1 Install the flame monitoring device at a vibration-free location. The installation site must be easily accessible to enable easy control of the visual checking controls during fur- nace operation. When replacing the flame monitoring device, the installation of device with the same marking is required. Make sure that the maximally permissible ambient temperature of the installation site does not exceed 60°C.
