Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property
damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific task
in accordance with the relevant documentation, in particular its warning notices and safety instructions. Qualified
personnel are those who, based on their training and experience, are capable of identifying risks and avoiding
potential hazards when working with these products/systems.

Note
•
The Milltronics BW500 and BW500/L are to be used only in the manner outlined in this
instruction manual.
•
These products are intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency based communications.
This instruction manual covers the operation, installation, and maintenance of Milltronics BW500
and BW500/L.
Please refer to this manual for proper installation and operation of your BW500 or BW500/L belt
scale integrator. As BW500 and BW500/L must be connected to a belt scale, and optionally a
speed sensor, refer to their manuals as well.
The manual is designed to help you get the most out of your BW500 and BW500/L, and it
provides information on the following:
•
How to install the unit
•
Outline diagrams
•
How to program the unit

Milltronics BW500
The Milltronics BW500 is a full-featured integrator for use with belt scales and weighfeeders. The
speed and load signals from the conveyor and scale, respectively, are processed to derive rate
of material flow, and totalization. The primary values of speed and load, and the derived values
of rate and total are available for display on the local LCD, or as output in the form of analog mA,
alarm relay and remote totalization.
Milltronics BW500/L
The Milltronics BW500/L is an integrator for use in basic belt scale or weighbelt applications. The
speed and load signals from the conveyor and scale, respectively, are processed to derive rate
of material flow, and totalization. The BW500/L does not include the advanced feature set for
control.
Milltronics BW500 and BW500/L features
BW500 and BW500/L support Siemens Milltronics Dolphin Plus software and Modbus protocol
on the two RS232 ports and the RS485 port for communication to customer PLC or computer.
BW500 and BW500/L also support Siemens SmartLinx for popular industrial communication
systems.
