3.3 Mode of operation

The compact flame detector converts the flame radiation pulsing of the burner flame into elec­trical signals. These signals are routed to an electronic changeover switch, which alternately
applies them to one of the independently working processing channels, where the signals are
digitised. This reduces the initial signal quantity to the information ’pulse period’ (information
carrier: pulse frequency of the flame radiation).
The digitised signals are compared with the related reference signals by means of a digital
frequency evaluation unit. This ensures that only those flame signals that are within the pre­selected frequency transmission range will be included in a continued processing, irrespective
of their original amplitude. A control switch (for the F200K2 only) located below the removable
cover allows the operator to change the lower frequency limit if required. After evaluation, the
flame signal is routed to the switching amplifier, which also controls the related shut-down
time.
A safe monitoring of the antivalent control states as well as the response and shut-down pe­riods is performed at the output of the signal processing channels, before an activation of the
output relays at the end of each signal processing channel is carried out. Antivalence faults
and deviation in time delays going beyond the admissible limit values result in the control state
’Flame out’.
The control states ’Flame out’ and ’Flame in’ are indicated on the rear side of the device by
means of a red and/or green LED. The change-over between the two signal processing chan­nels is indicated by pulsing of the green LED during the ’Flame in’ control state.
Additionally one or two six-step control switches provide for a sensitivity adjustment to adapt
the system to the flames to be monitored, this being indicated by means of a six-step chain of
green LEDs designed to be the device's flame intensity indicator.

Miscellaneous
Self-monitoring principle

Signal processing is carried out by means of two transmission channels working independent­ly of each other and alternately triggered. The output levels are permanently checked for an­tivalence within a given time grid.

Parameter adjustment, combustion system type monitoring equipment

Using the control rotary switch on the F200K/F200K2 compact flame detectors enables be­tween 6 and 12 sensitivity levels to be set. The F200K2 version allows an increased sensitivity
in range II to be set. A six-step green LED indicator indicates the evaluated flame intensity on
the rear side of the device. The transmission range of the digital flame frequency evaluation
allows for signal passage between10 ... 190 Hz (F200K1) and/or 10 / 20 / 30 ... 190 Hz
(F200K2).

4.3 Life Cycle

The F200K’s and FN20’s lifetime is rated for 10 years or 250.000 working cycles. The prob­ability of failure is considered on this basis. The real lifetime of F200K and FN20 is influenced
among others by the ambient temperature. Particularly operation in high temperatures reduc­es the lifetime.

6 Information for Mounting and Installation

6 Information for Mounting and Installation

6.1 Mounting - Basic Instructions

6.1.1 Safety

WARNING!

For the F200K version without mains frequency suppression, it is mandatory to mount it with
its viewing opening on the burner in such a way that it is protected against the detection of
mains frequency light. This mounting must meet the requirements of a tool mounting.
The LAMTEC mounting brackets FV30 and FV40 meet this requirement.
After attaching the union nut to the F200K /V, tighten the set screws located in this union nut
with an Allen key. This prevents unintentional disconnection of the connection.
Mounting in a cooler housing of the FS50, FS51 series also ensures tool mounting.
Advice on this is available from LAMTEC support.

Warning notice
The flame monitor without mains frequency suppression is provided with a warning: e. g.

6.1.2 UL Listed

WARNING!

WARNING After scanner commissioning tighten set screw
in scanner coupling nut!
Flame monitor without mains frequency suppression!

WARNING!

The fiber optic flame detector versions F200K.. IR-.. FO with IR sensors may only be used with
the LAMTEC IR Fiber optic FOR...-IR or FOF...-IR.

In preparation

NOTICE

For applications within the scope of the UL Listed certification procedure, it must be ensured
that the components used are "Listed" certified. That is, in addition to the flame detector used
must also be the connection cable and if used the power supply "Listed" certified.
The applicable installation rules according to NFPA70 (NEC) must be observed.

20

6 Information for Mounting and Installation

6.1.3 Basic mounting instructions

NOTICE

The cables are designed for a special temperature range (see chapter 4 Technical Data).
Do not open the devices in temperatures below -20 °C/-4 °F.

NOTICE

For the installation of an extension cable on site, make sure to use a separate, shielded ex­tensionable. Moreover, provide for good continuity of the shield and make sure that the shield

and functional earthing (FPE) are connected properly.

In order to reduce the risk of electromagnetic interference it is recommended that the supply
cable and extension cable, if used, are installed in separate containment away from any main
wiring (e.g. ignition lines, electrical motors, contactors, frequency inverters). Parallel cable
routing with mains cables should be strictly avoided.

NOTICE

Very high levels of electromagnetic radiated noise may result in sporadic problems in flame
detection, or may even avoid proper detection at all.

NOTICE

The radiation emitted by a flame contains an element of flicker (pulsating).
This characteristic is a result of the processes that occur during combustion. This oscillation
(flame frequency) is used for flame monitoring. The flame detector should be installed at the
burner viewing port using a suitable mounting device to ensure that the burner flame remains
perfectly visible throughout the full modulating/operating range of the furnace. To install a se­lective monitoring device the viewing port should be located such that the flame sensor can
be aligned to detect the base of the flame adjacent to the burner mouth (perhaps 'head' might
be better). The detector should be aligned so that it cannot 'look' directly into adjacent flames
or flames located on the opposite side of the furnace. Consideration should also be given to
ensure that background flames, such as coal, wood and waste, cannot be detected.

21

6 Information for Mounting and Installation

The compact flame detector:

– is to be aligned in such a way as to cover the first third of the flame for single monitoring.
– has to cover the flame root area for a simple selection during the ’Flame in’ control state

(area of high flame frequencies), and during the ’Flame out’ state to only detect the resid­ual radiation caused by the ’offshoots’ of the other flames in the combustion chamber (ar­ea of low flame frequencies) or by reflection.

– If possible avoid aligning the compact flame detector parallel with the flame axis, since

in this position, a loss of flame can hardly be detected.

In order to reach a high availability and a high selection quality , it is very important to place the
compact flame detector at the appropriate location.

Make sure in every case that the aperture angle for the UV solutions is only about 8°. For this
reason we recommend to use the FH40, FV40, FS 51and/or FS 56 adjustable holding device
(ball-and-socket joint), unless already in place. Correct alignment is of paramount impor-
tance in particular in such cases where there is an additional viewing tube inside the burner
or where the visibility of the flame is considerably restricted. With increasing length of the
sighting tube is a correspondingly larger cross-section advantageous.

NOTICE

The installation should take place with the holding device provided by LAMTEC.
Otherwise pay attention to an isolated mounting to avoide any interference from compensat­ing currents provoke over the cable shield.

The installation site must be easily accessible to allow a perfect observation of the visual op­erational controls even during operation of the furnace. When replacing the compact flame de­tector, make sure to install a device having the same identification marking.

Make sure that the maximum admissible ambient temperature is not exceeded at the in­stallation site. This applies in particular to radiant heat.
