1 Safety Instructions
1.1 Description Conditions
a) High danger of health injury or loss of life
Danger
This symbol refers to high risk for persons to get health injury or loss life. It has
to be followed strictly.
b) Risk of damage of machines
Caution
This symbol refers to information, that, if ignored, could cause heavy
mechanical damage. This warning has to be followed absolutely.
c) Note for proper function
Note
This symbol refers to an important information about proper use. If not followed,
malfunction can be the result.
1.2 List of Safety Instructions
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.
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.
Bad earth connection may cause electric shock to persons, malfunction of
the total system or damage of the control unit! It is vital to ensure that
proper earth connection is done.
Some contacts on the terminal board of the 230VAC version are under
230V tension! Mortal danger! Disconnect power supply before open the
housing!

2 Definitions
Measuring uncertainty: Each measuring device has some inaccuracy, but
however, inaccuracy is in a small, defined range of tolerance. This deviation of the
measuring value referring to the effective value is called measuring uncertainty.
Measuring accuracy: Its behaviour is the contrary to the measuring uncertainty:
Increases the uncertainty, decreases the accuracy, and also in reverse mode.
Force measuring bearing: Measuring device using strain gauges, which converts
the load of the measuring roller into electric signals.
Proxy switch: Inductive distance sensor which is used for gearless and contact-
less switching
3 System Components
The Belt scale for bulk conveyors BMGZ600A consists of the following components
(refer also to fig. 1):
Measuring roller
For acquisition of roll load and belt speed
Flat or troughed measuring roller
Simple mounting also to existing systems thanks to the all-purpose mounting
elements
All parts are fully zinc galvanized
Evaluation electronic unit
For excitation of the sensors and amplifying of the measuring signal
With operation panel for parametrization
It is possible to connect external displays
Interface RS232
Interface PROFI-BUS®
Some different housings available
For 1 measuring roller (BMGZ610A/611A) or 2 measuring rollers (BMGZ620A)
Additional digital inputs and outputs for extended functions such as
proportioning belt weighers, etc. (BMGZ611A)
External display
Telecounter to show the charge value

4 System Description
fig. 1: Basic structure of the belt scale BMGZ600A B620001e
4.1 Functional Description
The belt scale for bulk conveyors works according to the principle:
Flow rate = weight * speed
The measuring roller measures the load on the belt and the belt speed. This
information are transmitted to the electronic unit, which calculates actual flow
rate, charge weight and daily output. Using a printer, the raised quantity can be
printed to a charge protocol at any time.
4.2 Measuring Roller
The measuring roller is mounted between 2 support rollers under the belt. The
measuring roller whose shape corresponds to the shape of the belt is supported
on both sides on FMS force measuring bearings. The measuring bearings take up
the force directly at its origin and do not show any sensitivity to belt direction.
Therefore, no force decoupling gear is necessary.
The measurement of belt speed is achieved by means of a pulse generator which
is integrated in one of the force measuring bearings.
The maintenance-free, robust and compact design provides high reliability and
durability.
4.3 Evaluation Electronic Unit
The evaluation electronic unit contains a micro-processor to handle all
calculations and communications, the highly accurate sensor power supply and
the signal amplifier for the measuring value. As operation interface it provides 6
keys and a 2x16 characters display in the front of the electronic unit. All inputs are
saved in an EEPROM. The evaluation electronic unit has no jumpers or trimmers to
keep most accurate long-time and temperature stability.

The versions BMGZ610A/611A provide evaluation of 1 measuring roller; version
BMGZ620A provide evaluation of 2 measuring rollers. Versions BMGZ611A
provide additional digital inputs and outputs which can be used for extended
control functions such as proportioning belt scales, etc.
All versions support an RS232 interface. For ex. a master computer (PC) or an
external printer may be connected to the RS232 interface. As options, an
additional board with PROFI-BUS® interface and a printer are available.
4.4 External Displays
Analogue displays can be connected to the analogue outputs to show the actual
flow rate. Telecounters can be connected to the digital pulse outputs (relays) to
show the charge value.

The block diagram above shows the function of the belt scale BMGZ611A. The
BMGZ610A has no outputs Min. limit 1, Max. limit 1, Pre detect charge 2 and Ref.
charge 2, and has no inputs and as charge activ 1.
The belt scale BMGZ620A is designed according to the same principle, but all
