General aspects Warning notes The following warning notes are used in these operating instructions: This warning level indicates an imminent hazardous situa- tion. If the hazardous situation is not prevented, this will result in death or severe injury. Follow the instructions that accompany this warning to prevent the risk of death and severe personal injury.
These operating instructions have to be treated as confi- dential. They may only be used by authorised staff. Ac- cess by third parties may only be granted upon written agreement of BFI Automation. All documents are protected in keeping with the German copyright law.
• non-performance of specified maintenance work It is recommended that the operator of the device con- cludes a service contract with BFI Automation. This guar- antees that the device is regularly checked by our service staff and ensures that any required wearing and spare...
General aspects Obligation of the operating company The flame scanner may cause hazards if it is operated in- appropriately or in an improper condition. The operating company is under the obligation to operate the machine in proper state only. The operating company has to secure hazardous areas that exist between BFI de- vices and the customer's own equipment.
BFI Automation for consequential damages. BFI Automation is liable for possible errors or omissions with the exclusion of additional claims entered into in the framework of the warranty obligations conceded to in the contract.
Safety Safety Intended use The flame scanner shall be used exclusively to detect flames in combination with a suitable flame amplifier. The flame scanner and flame amplifier together constitute a complete flame amplifiering system for burners with a ran- dom capacity and random fuels in single and multiple burner systems.
Safety Requirements on persons Work on/with the device may only be performed by per- sons authorized to do so based on their training and quali- fication. Furthermore, such persons have to have been commissioned by the operating company. Do not allow any persons who are being apprenticed, ed- ucated, instructed or on a general training programme to work on the device without the constant supervision of an experienced person.
Safety Safety instructions The following instructions on accident prevention have to be observed when operating the flame scanner. Only operate the device if it is in a proper state ! • Do not remove or disable safety devices. • Check for externally noticeable damage and defects prior to using the device ! Immediately notify the appro- priate authority/person of any changes that occur (in- cluding changes in operating performance).
Safety Safety devices 2.4.1 Fundamental aspects Check the safety equipment and locking devices on the device for safe operational condition. Only operate the device if all safety devices are present and enabled. The operating company or operator of the flame scanner is responsible for the proper operation of the device.
• Operating and auxiliary materials as well as exchanged parts have to be disposed of in a safe and eco-friendly way. • Spare parts supplied by BFI Automation or approved of by BFI Automation only may be used.
Safety 2.5.2 Electrical / electronic devices Danger to life caused by electrical current! Contact with live wires or components presents a danger to life ! Prior to any work on the electrical equipment, disconnect the flame amplifiering system from the power supply net- work ! In keeping with the electrical regulations, work on electri- cal / electronic parts / components may only be carried...
Safety 2.5.3 Testing in keeping with the German Work- place Safety Ordinance (BetrSichV) In case of the coupling or installation of devices from vari- ous manufacturers or suppliers, the operating company has to carry out a precise test, prior to start-up, in keeping with the German Workplace Safety Ordinance (BetrSichV) in force and the applicable electrical regulations.

Report any damage After arrival of the device and accessories, notify the ship- ping agent, the insurance company and BFI Automation immediately in case of any damage caused by transport or inadequate packaging. Take steps to minimise and prevent further damage.
Transport, installation and connection Packaging The flame scanner is shipped in different packaging mate- rials. The most frequently used packaging materials are card- board and plastics (foils, foamed material). Packaging has to be disposed of in an environmentally friendly way and in accordance with the relevant provi- sions on disposal.
Transport, installation and connection Installation All installation and connection work may be carried out by qualified and approved specialist staff only !

The length and the diameter of the sighting tube have a direct influence on the usable flame radiation as the visual angle of the lens system is defined.
The exit of hot gas after removal of the scanner is prevented, ensuring further cooling and purging of the arrangement. The entire mechanical peripheral system can be supplied by BFI Automation. Harting plug Sighting tube Special cable KW5...

Transport, installation and connection been moved or the flame image has been changed (by additional fuel, new burner, change in the burner / air reg- ister, for example) as well as during all first installations. For selective burner amplifiering, the device has to be in- stalled in such a way that the primary combustion zone in all load ranges is inside the visual angle of the flame scanner.
Transport, installation and connection Connection 4.7.1 Electrical connection Danger to life caused by electrical current ! The safety instructions and local safety regulations have to be observed during connection ! For connection data, please refer to the chapter titled "Technical data" as well as to the following terminal dia- gram.
Transport, installation and connection Prior to the connection of the flame scanner, observe the separate operating instructions of the flame amplifier (System 3000) ! 4.7.2 Laying the special cable KW5 for standard housings No contact chamber may remain bare ! All contact chambers in the contact insert have to be fitted with crimp contacts ! For this purpose use a suitable crimp tool (BFI part No.
Transport, installation and connection 4.7.3 Handling of the KW5-Shieldings Outer shielding: The outer shielding is only connected to the device via the cable gland. On the loose cable end the shielding should be cut off short. Inner shielding: The inner shielding has to be connected to ground of the flame amplifier side.

Description Description Functional description 4.0 The flame scanner 4.0 utilizes the well approved integral procedure of the flame radiation analysis. A silicon photo element senses the electro-magnetic radiation released during the combustion process from near ultraviolet to near infrared. The evaluation of the flame modulation resulting...
Description Optical aperture With an optical aperture the intensity of the radiation to the sensor (3) can be reducedng. If the smallest hole is positioned prior to the sensor the radiation is lowest. The aperture can be used in 4 different positions. The aperture is mechanically connected to the detector holder.
Operation of the flame scanner Operation of the flame scanner For the operation of the flame scanner, please observe the separate operating instructions of the flame amplifier. The response of the flame scanner depends on the burner configuration as well as on the air flow and the spectral characteristic (wave length).
Maintenance and servicing Maintenance and servicing The flame scanner requires no maintenance. For cleaning, use a moist cloth to wipe the housing from the outside only. Do not scratch the lens !
