TECHNICAL DESCRIPTION

EDITION: TB CFC2000-REV.5 2012-03-07

Important: Please note, that all mounting and wiring as well as all changing or adjustment at
the flame monitoring and evaluation equipment should only be carried out by fully
trained and authorized personnel.
BFI Automation is pleased to support you if you do not have any experience with
the equipment. Our service personnel is carrying out world wide installations, su-
pervision and commissioning and is available upon request.
For the stage of planning you can ask our sales and project engineers for any
support you may need.
BFI Automation is providing any kind of training for your engineers.

CAUTION: In order to guarantee a proper operation the compact

flame controller must be tested several times at all conditions. The
burner has to be started and stopped several times (the flame relay
! must always interrupt reliably with no flame on). Carry out these tests

on different boiler loads. This is a vital assumption for a proper and
