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;
