6 Installation and Wiring
Caution
Proper function of the FMS belt scale is only guaranteed with the recommended
application of the components. In case of other arrangement, heavy malfunction
can be the result. Therefore, the installation instructions on the following pages
must be followed strictly.
Caution
Local installation regulations are to preserve safety of electric equipment. They
are not taken into consideration by this operating manual. However, they have
to be followed strictly.
6.1 Determination of Mounting Place of the Measuring Roller
To preserve fault-free operation and best accuracy, the following points should be
observed when designing the conveyor and determining the location for the
measuring roller:
 Belt tension should be kept constant. A weighted belt tensioner should be
provided for this, if possible. Deviations of the belt tension have direct influence
to the measuring result.
 Belt rise must be only as high as the bulk material on the belt cannot move
downwards.
 Flow rate should be within a range of 20...100% of the rated nominal
performance. If flow rate is lower, measuring accuracy will be less.
 The belt scale should be placed as far away as possible from the material feed
to allow the bulk material to settle.
 The belt scale should be placed as far away as possible from the drive roller to
minimize the influence of belt tension.

The belt scale may only be installed in a straight section of belt with constant
trough.
Note
Movement of the bulk material on the belt or changes of the belt tension will
cause immediately and non-controllable changes of the measuring value and
will therefore enlarge the measuring uncertainty. Proper operation is provided
only if the points above are followed.
Mounting position
There are in fact three mounting positions possible: horizontal conveyor (fig. 7),
inclined conveyor (fig. 8), and angled conveyor (fig. 9). In any way, the
measuring roller should be located as far away as possible from the drive roller.
