1. APPLICATION
MW-01 weighing module is intended for conftruction of industrial load cell
scales. Depending on the needs, communication with the module may be
established by the following interfaces: RS232, RS485, Ethernet, Profibus
and ModBus protocol. MW-01 Module may cooperate with PUE 5, PUE 7
terminals or PC computer.
Operating of the weighing module MW-01 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 MW-01 user manual.
2. PRECAUTIONARY MEASURES
A. Please, read carefully this user manual and use the device according
to its intended use;
B. Weighed loads should be placed possibly in the central setion of the
weighing platform;
C. The weighng platform should be loaded with objects which gross
weight does not exceed the maximal capacity of the scale;
D. Do not leave heavy loads on the weoghing patform for longer period
of time;
E. In case of failure, immediately disconnect the power supply;
F. Devices that are to be decommissioned should be utilized according
to valid legal regulations.
3. WARRANTY CONDITIONS
A. RADWAG is obliged to repair or change those elements that appear
to be faulty because of production and 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 defecting
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 people,
•Removing or destroying protection stickers for the weighing module
F. The detailed warranty conditions are listed in the warranty certificate.
G. Contact with Authorized Service: [phone] ext. 106 or 107.
