1.INTENDED USE
The MW-01 mass converter is designed to be a component of an industrial
load cell scale. Depending on the needs, communication with the mass
converter can be carried out via the following communication interfaces:
RS232, RS485, Ethernet, Profibus and ModBus RTU/TCP protocol.
The MW-01 mass converter can connect with PUE 5, PUE 7.1, PUE HY10
indicators or a PC. It enables complete control of programmable PLC
controllers. In order to operate the mass converter via a PC, run
"MW Manager" software. For detailed description on the software refer further
down this user manual.
2.WARRANTY CONDITIONS
A. RADWAG feels obliged to repair or exchange all elements that appear
to be faulty by production or by construction.
B. Defining defects of unclear origin and means of their elimination can only
be realized with the assistance of the manufacturer and the user
representatives.
C. RADWAG does not bear any responsibility for damage or losses
resulting from unauthorized or inadequate performing of production
or service processes.
D. The warranty does not cover:
mechanical damage caused by inappropriate exploitation, damage
of thermal and chemical origin, and damage caused by lightning,
overvoltage in the power grid or other random event,
inappropriate cleaning habits.
E. Loss of warranty takes place if:
a repair is carried out outside RADWAG authorized service point,
service claims intrusion into mechanical or electronic construction
by unauthorized people,
the device does not bear security seal stickers.
F. For detailed warranty conditions read the service card.
G. Contact with the central authorized service: [phone].
