6.2 Installation
6.2.1 External installation
Output contacts
The flame detector ready for operation delivers the "Flame in" or "Flame out" status
message to a floating output contact. Further signal processing has to be carried out
by the controller 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 compo-
nents of the radio interference suppression unit.
Remote switch-over of sensitivity
The remote switch-over may only be effected by using a floating contact via the 24V
supply of the flame detector.
Intensity remote display (4 / 0 - 20 mA current loop)
Only potential-free devices may be connected complying with the requirements for
protective low voltage (SELV) (safe insulation according to DIN EN 50178).
