0 Foreword
The purpose of this manual is to help you to become acquainted with your
DURAG product.
In this publication you will find information and technical data on planning,
installation / commissioning, operation and maintenance of the D−LX 200,
D−LX 720.
The two device types D−LX 200 and D−LX 720 are identical in design, apart
from the respective optics. Therefore both designations are always specified in
this manual, separated by a comma. The differences, exclusively in the front
part of the devices (the D−LX 720 is intended for use with an optional fibre-
optic system), are described in the relevant chapters, identified accordingly.
The functional diagram of the complete system and the device components
complete this information.
Our aim is to make a decisive contribution to your success with our products
and services. We hope that the information provided here will enable us to do
so.
Flame monitors are safety devices and are designed to ensure the safe
operation of a furnace plant.
The adjustment of flame monitors should therefore only be performed by
appropriately trained personnel. DURAG offers suitable training for this
purpose.
Should you have any further questions on products or applications from the
DURAG GROUP, please use our Support & Service!
You will find the relevant addresses and telephone numbers on page 115
(DURAG GROUP company addresses).
Further information is also available from www.durag.de
Please read this manual carefully before commissioning the Compact Flame
Monitor! The information provided is important for your safety and for
preventing damage to the D−LX 200, D−LX 720 and to the environment.
