5 Instructions for Maintenance 5.1 Display and Operational Controls Represented in chapter 6.1 Layout of the Operational Controls. 5.1.1 Sensitivity Range - Indication This display type only exists in the F200K2 execution type. The display shows the sensitivity ranges I or II activated by external selection. The range I (normal sensitivity) is mainly used for high flame intensities, whilst range II (higher sensitivity) is used for weaker flame intensi- ties. 5.1.2 Operating State - Indication The red LED shows the ’Flame OUT’ operating state. Whilst indicating 'Flame IN' the green LED pulses in intensity to indicate the self-monitoring operation of the system. The pulse fre- quency is the same as the self-monitoring cycle time (1.5 or 3.0 seconds). If the green LED does not pulse then this could be symptomatic of electromagnetic interference (EMC) or a de- fect of the compact flame scanner. (refer to chapters from 5.2.4 Fault on Flame Detection to chapter 5.2.6 Faults During Operation and chapter 5.3 Troubleshooting). 5.2 Commissioning 5.2.1 General Information 5.2.1.1 'Flame Out' State After switching on the power supply, the flame scanner is ready for operation after approxi- mately 5 seconds. The following display has to be shown: 5.2.1.2 'Flame In' State To check the monitoring parameters, install the compact flame scanner in the specified mount- ing place before starting the operation of the furnace. If the flame burns naturally, the display should change as follows: - Display ’Flame out’ ’Red’ LED lights up - Sensitivity range I or II ’Yellow’ LED lights depending on external pre-selec- tion f. range I or II (for F200K2 only) ’Red’ LED Goes out ’Green’ LED Lights up, changing its radiation intensity antivalently to the cycle rhythm of the self-monitoring system. Intensity indicator (lighting point) should reach 100%.

5.2.1.3 Operating mode switchover Two preselectable operating modes The compact flame scanner F200K offers users two operating modes for selection. This makes it possible to select two different settings in the range of gain levels. The individual op- erating modes can be switched during operation. 5.2.2 Preparations 5.2.2.1 Checking the Compact Flame Scanner The flame scanner can be checked for proper functionality without a flame being present. 1 Carry out the complete electrical installation of the flame scanner and connect it to thesup- ply voltage. A LAMTEC test emitter of the FFP30 type (IR + UV) can be used as an aux- iliary means for flame simulation. 2 Simulation of flame radiation in front of the flame scanner's viewing port. This can be achieved using a lighter or any other type of a modulated-light source (do not use the mains frequency) having a sufficiently high intensity. For example the light from a lamp can be modulated by moving splayed fingers to and in front of the bulb. The flame scanner will switch on its output contacts if the flame signal is simulated for a suffi- cient period of time. This is indicated by the extinction of the red LED and the pulsating light of the green LED. The 6-level intensity indicator illuminates. If no flame signal is indicated despite apparent correct functionality then check the output con- tact (s. Kapitel 5.3 Troubleshooting) 5.2.2.2 Optics There are no special requirements for locking discs or similar components when using IR- flame scanners. Small accumulations of dirt due to dust and similar materials are generally not critical for flame detection. In UV- flame scanners, the requirements for locking discs are more critical. Ensure that ma- terials, such as quartz, that allow UV light to pass through freely are used. These materials are used in the LAMTEC UV adjustable holding devices (FH30, FV30, FH40 and FV40) Small accumulations of dust, water and other contaminants are much more likely to affect the per- formance of flame detection than when using an IR scanner. WARNING! When using an F200K without mains frequency suppression, it must be ensured that it is pro- tected against the detection of mains frequency light. The mounting of the sight opening on the burner must meet the requirements of a tool mounting. Unintentional loosening of the F200K must be prevented. Advice on this is available from LAMTEC support.

5.2.3 Checking the Flame Shut-down on Fault WARNING! Simulate a flame rupture or flame extinction by shunting off the fuel supply to the burner to be monitored by the flame scanner. Check that the signal for shutting-off the safety valve is trig- gered off within the period of TS< 1 s (on safety period ’Operation’ at tVOff = 1 s) after extinc- tion of the flame. WARNING! For the IR compact flame scanners of the F200K1(2) IR-1 and/or F200K1(2) IR-2 types, take into account the radiation effects characteristic of the combustion chamber. Consequently, switch-off tests should be carried out when the boiler has reached operating temperature. In particular, make sure that the sensitivity of the compact flame scanner is increased only to such a value required to safely and reliably monitor the flame throughout the operating range of the burner. 5.2.4 Fault on Flame Detection Check this function according to chapter 5.2.2 Preparations -5.2.2.1 Checking the Compact Flame Scanner. 5.2.4.1 1. Interference Generally, interference becomes apparent by the fact that the intensity indicator of the device may indicate 100 %, but the green LED (’Flame in’) does not light up. Or, the green LED lights up for a moment, but then it does not change its intensity according to the cycle rhythm and goes out again. This is a cycle synchronisation fault (signal in both evaluation channel present at the same time). This may chiefly be due to the interference emission of the ignition trans- former during ignition. – Check the shielding and FPE for proper connection to the F200K – Carry out a proper grounding of the ignition transformer – Check the cables for laying and if required untangle / separate them spatially 5.2.4.2 2. Excessive Temperatures Make sure that the maximum allowable ambient temperature of 60 °C is not exceeded at the installation site. In case where the temperature is expected to exceed the limit, take appropri- ate cooling measures (e.g. cooling air enclosure FS 50, FS 51or FS 56). Make sure that the flame scanner casing does not heat up beyond this temperature value due to the impact of the heat radiated by the boiler. Overheating will result in a sensitivity loss in the first line, or will cause damage to the sensor elements and with it may result in a total fail- ure of the system. ’Red’ LED lights ’Green’ LED dark

5.2.5 Faults During Ignition Faults occurring during ignition may have several causes. 1 In case of additionally monitoring of pilot flame and main flame, the pilot flame may not sufficiently be detected. • Check the pilot flame for stable operation 2 Interference Refer to chapter 5.2.4 Fault on Flame Detection 3 Defect in the device. 5.2.6 Faults During Operation Faults occurring during operation may have 3 causes. 1 The main flame may not sufficiently be detected. – Check the main flame for stable operation - provide for visibility throughout the oper- ating range 2 Interference 3 Defect in the device.

5.3 Troubleshooting on apparently immaculate functioning according to the indicator elements 1 Check the output contact fuse and the contact – Disconnect the flame scanner from the supply voltage – Check the normally closed output contact at the 1st clamping point behind the flam scanner between the brown (BR) and the white (WH) connection wire (avoid low re- sistance continuity check - fuse 500 mA) – Connect the flame scanner to the supply voltage – Check with simulated flame between the brown (BR) and the green (GN) connectio wire 2 Check the supply voltage – Connect the flame scanner to the supply voltage – Check the supply voltage at the 1st clamping point behind the flame scanner betwee the red and the blue connection wire for compliance with the voltage limits (in particu- lar the lower limit) – Repeat test with simulated flame 5.4 Maintenance 5.4.1 General Information Provisions shall be made to ensure that the light entry port of the flame sensor and the viewing port on the furnace, where the sensor is fitted, are regularly cleaned, i.e. at regular intervals, which depend on the operating conditions of the furnace. The compact flame scanner needs no maintenance. The operation of the flame scanner by physically shutting off the flame should be incorporated into the maintenance cycle for the device. NOTICE If it is necessary to clean the optics of fiber optic flame detectors, special care should be taken to clean the fiber optic surface. Damage to the surface can result in significant signal loss. 5.4.2 Instructions on Troubleshooting DANGER! The flame scanner is a safety device. Any repair work or other changes to the device shall only be carried out by the manu- facturer's specialist staff or by some other persons appointed by the manufacturer. Any other person are not allowed to operate on parts inside the device. In particular, this concerns the unauthorized exchange of the flame contact fuse.
