
First of all, the 2 light guide ends have to be mounted according to their marking (1+2). They
are mounted with their metal screwing ends in the connection adapter OA-bi which is situated
in the housing wall of the pre-amplifier K-FA-H for mounting in "cold area" by turning right-hand
until limit stop.

Push one angled light guide end according to the marking (2) into the location hole on the left
side of the sensor head FA2-H. Push them as far as they touch the measuring glass of the
flowmeter e.g. FM1-H.

Push the other angled light guide according to the marking (1) as far as possible into the
location hole on the right side of the sensor head FA2-H so that the light guide ends touch the
measuring glass of the flowmeter.
N O T E !
In case the light guide ends cannot be pushed deep enough, the fastening
screws in the front side of the sensor head must be unscrewed accordingly
by turning left-hand.

The light guide ends are fixed in the sensor head with one fastening screw each by turning
right-hand.
C A R E ! Fasten the light guide ends only fingertight.
N O T E !
The conception of the forked light barrier guaranties a problem-free function
in normal day light or normal ambient light. A strong light from outside to the
sensor must, however, be avoided.

Mount the pre-amplifier K-FA-H and electronic controller FA1-... A distance of 200 meters
between pre-amplifier and electronic controller is no problem.
12 ELECTRICAL CONNECTIONS
W A R N I N G !
False supply voltage can damage the equipment. When connecting
the equipment, please ensure that the supply voltage is identical
with the information provided on the model type plate!
N O T E !
For the assembly of power installations with rated voltages up to
1000V, the requirements of VDE 0100 and relevant standards and
specifications must be observed!
The main circuit is equipped with a fuse corresponding to the
nominal current (over current protection); for electrical details see
technical data (chapter 8 and manual 5-6.10ME).
