1.INTENDED USE
Weighing module MW-04 series is intended to design industrial load cell
scales. Depending on application, communication with the weighing module
can be carried out through the following interfaces: RS232, RS485, Ethernet
and Profibus. The MW-04 is designed for cooperation with terminals PUE 5
or PC computers.
Operating of the weighing module MW-04 from a PC level is carried out with
a computer software “MwManager”. A detailed description of the application
is included in the further section of the weighing module user manual.
2.PRECAUTIONARY MEASURES
A. Before putting into use read carefully this user manual. Use the device
as intended;
B. Weighed loads should be placed possibly in the central section of the
weighing platform;
C. The weighing platform should be loaded with objects which gross
weight does not exceed the maximum capacity;
D. Do not leave heavy loads on the weighing platform for longer period
of time;
E. In case of failure, immediately unplug the device from power supply;
F. Devices that are to be decommissioned should be decommissioned
according to valid legal regulations;
3.WARRANTY CONDITIONS
A. RADWAG is obliged to repair or change those elements that appear
to be faulty by production or construction reason,
B. Defining defects of unclear origin and outlining methods of their
elimination can be carried out only in participation of the user and
the manufacturer representatives,
C. RADWAG does not take any responsibility connected with defects
or loss deriving from unauthorized or inappropriate (not adequate
to manuals) production or service processes,

6
D. Warranty does not cover:
•Mechanical failures caused by inappropriate exploitation
of the device or failures of thermal or chemical origin or,
•Defects caused by atmospheric discharge, overvoltage in mains
or other random event,
•Maintenance activities (cleaning of the weighing module).
E. Warranty loss appears if:
•A repair is carried out by an unauthorized service,
•Intrusion into mechanical or electronic construction
of unauthorized personnel,
•Removing or destroying protection stickers for the weighing module.
F. The detailed warranty conditions are listed in the warranty certificate.

5.CONSTRUCTION
The weighing module MW-04 series comprises a metal housing. The signal
cables are assembled on glands. MW-04 communicates with peripheral
devices through one of the available interfaces: RS485, RS232, Ethernet,
Profibus.

The weighing module enables cooperating with a terminal PUE 5 series or a
PC computer. It features 4 optoisolated inputs and 4 outputs type OptoMOS.
The MW-04 is supplied from mains 100-240VAC.
