External Installation
EMC emission
Compliance with the requirements with respect to the EMC emissions are proven for the de-
vice as part of the type test. After installing the device in the equipment an extra EMC type
testing is not necessary.
Output contacts
The flame detector ready for operation delivers the ’Flame ON’ or ’Flame OFF’ status mes-
sage to a floating output contact. Further signal processing has to be carried out by the con-
troller adapted to the related furnace.
To guarantee a high safety level make sure when installing the
output contacts
to lay out the
circuitry of the
radio interference suppression
system to be provided by the user in such a
manner as to avoid
shorting-out
of the contacts due to faulty components of the radio inter-
ference suppression unit.
Power supply, Output contacts
WARNING!
For the power supply of the flame detector and for potential separation of the flame detector
contact use the FN20 power supply. Instead of FN20 a safety power supply must be used to
generate the power supply of the flame detector (eg. According to EN61558-2-6 or
EN 60950-1).
DANGER!
The output contacts of the Flame scanner are approved for use with SELV or PELV only.
Remote switch-over of sensitivity
WARNING!
Use a floating contact which is feeded by the flame detector's 24 V supply for the remote
switching of the F200K2's range. Or use a SELV or PELV power supply according to 60730-1
or EN 60950-1 (i.e. a safety power supply).
Intensity remote display
(4 / 0 - 20 mA current loop)
WARNING!
The current loop for remote indication of the flame intensity must be connected to devices
which have a safe isolation of the measuring circuit to dangerous active parts in accordance
with EN 61140 ( e.g. by double or reinforced isolation in accordance with EN 61010-1). This
can be, for example, passive instruments or isolating transformers with galvanic 3-way isola-
tion.
NOTICE
If the connection cable is subjected to particular stress caused by UV radiation, the connection
cable protective tubes provided for this purpose must be used.
