2Safety instructions
All safety, operating, and installation instructions given here serve to ensure that the
device functions properly. They must be observed in all circumstances to ensure the
safe operation of systems. Failure to comply with the safety instructions or use of the
devices outside of the specified performance characteristics may endanger the safety
and health of persons.
Work relating to the operation, maintenance, conversion, repair, or configuration of the
device described may only be performed by qualified personnel.
2.1 Representations of safety instructions

2.2 General safety instructions
The functionality of the conveyor belt scales is only guaranteed if the
components are installed in the recommended configuration. If not,
there is a risk of serious malfunction. The installation instructions on
the following pages must therefore always be followed.
The on
-
site installation regulations serve to ensure the safety of
electrical systems. These regulations are not taken into
consideration by this operating manual. However, they must always
be observed nonetheless.
Improper earthing may cause electric shocks to people, malfunctions
of the entire system, or damage to the evaluation unit! It must
always be ensured that the housing is properly grounded.

3Product information
3.1 System configuration
Illustration 1: Measuring roller and evaluation unit BMGZ700_BA_Manual.ai
3.2 Product description
The evaluation units in the BMGZ700 series are designed to meet the demanding
conditions of applications in mobile and stationary conveyor systems. The illuminated
graphical display shows the current flow rate, the daily amount, the total amount, and
the belt speed. Additional display devices and controls can be connected via the
configurable analogue and digital outputs. The web browser, included by default, allows
the measuring roller to be quickly configured, e.g. with any PC or laptop, or by remote
access.
An integrated PROFINET interface is available as option.
3.3 Functional description
The evaluation units in the BMGZ700 series convert the measuring signals from the
measuring roller into digital form. The weight of the measuring roller and the load from
the belt (taring) are subtracted from the measured value, and the resulting difference is
multiplied with the belt speed. The evaluation units in the BMGZ700 series have an
auto-taring program that automatically determines the tare value over two belt
revolutions by pressing a button.
3.4 Scope of delivery
Included in the delivery:

-Use the rubber mounts if the system experiences vibrations
4.1 Electrical connection (see installation instructions for the FMS
measuring roller)
The connection between the measuring roller and the evaluation unit must use the 8-
core twisted-pair cable (min. 4x2x0.75 mm2) provided.
The cable must be laid away from any power cables to ensure that no interference is
induced in the measurement signal. On the measuring roller side, remove the plastic
sheath of the cable over a length of approx. 14 cm.
The white wire is not required. Connect the shield to terminal 5.
On the evaluation unit side, remove the plastic sheath over a length of a approx. 25-54
cm. The white wire is not required.
The cable shield must be connected on both sides.
For the K version of the housing (cabinet), feed the cable with the 8-pin plug through the
cabinet wall.
