PRECAUTIONS
Prior to installation, operation or maintenance activities, carefully read this user
manual. Follow the instructions strictly.
Prior to the first use, carefully read this user manual. Use the device only
as intended.
Protect the device against considerable temperature variation, solar and
UV radiation, substances causing chemical reactions.
The device must not be operated in hazardous areas endangered with
explosion of gases, and in dusty environments.
In the case of damage, immediately unplug the device from the mains.
The device to be decommissioned must be decommissioned in
accordance with valid legal regulations.
If the module is to be operated in conditions that are difficult due to
electrostatics (e.g. printing house, packing centre, etc.), you must connect
it to the earth wire. To enable this, the device features functional earthing
terminal, marked with symbol.

1.INTENDED USE
The MW-04 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 protocol. The MW-04 mass
converter can connect with PUE 5.15, PUE 5.19, indicators or a PC.
Operation of the MW-04 mass converter via PC is carried out using
MwManager software. For more information on the MwManager software read
MwManager manual.
2.WARRANTY CONDITIONS
A. RADWAG is 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 product exploitation other than
intended, damage of thermal and chemical origin, damage caused by
lightning, overvoltage in the power network 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. Warranty conditions outline the warranty period for rechargeable
batteries attached to the device for 12 months.
G. For detailed warranty conditions read the service card.
H. Contact with the central authorized service: [phone].
3.MAINTENANCE
In order to clean the weighing instrument risk-free, it is necessary to disconnect
the device from the mains.
Avoid using cleansers containing any corrosive chemicals, e.g. bleach
(with chlorine). Do not use cleansers containing abrasive substances. Always
remove the dirt using microfiber cloth to avoid damage of protective coating.

6
In the case of a daily maintenance:
1. Remove the dirt using cloth dipped in warm water.
2. For best results, add a little bit of dishwashing detergent.
4. SERVICE AND REPAIR
In the case of any sign of damage, it is necessary
to disconnect the device form the mains immediately.
The damaged component must be replaced or repaired by
RADWAG service directly.
In the case of any problems with correct operation of the device, contact the
closest manufacturer's service point.
In the case of defects, deliver the faulty product to the manufacturer's service
point. If the product cannot be delivered to the manufacturer's service point, call
the service and report the defect. Repair scope and method will be set up.
The user is NOT ALLOWED to carry out any kind of repair
of the device himself/herself. Any attempt of module
modification, repair etc., by unauthorized persons, will result
with loss of validity of manufacturer-issued certificates,
declarations and warranty.
5. RECYCLING
MW-04 mass converters must be recycled, they are not to be treated as a
regular household waste. Devices to be decommissioned must be
decommissioned in accordance with valid legal regulations.
6.MECHANICAL DESIGN
The MW-04 mass converter is equipped with metal housing. Signal cables are
fed through cable glands. Communication with peripheral devices is carried out
via one of the following communication interfaces: RS232, RS485, Ethernet,
Profibus. MW-04 converter is equipped with 4 optoisolated inputs and 4 Opto
MOS outputs. It is powered with 100÷-240 VDC voltage.

7. INSTALLATION
7.1. Unpacking and Installation
A. Take the mass converter out of the packaging.
B. Connect the weighing platform to the mass converter, next place the
weighing device on a flat and even surface. Keep it away from any
sources of heat.
C. Level the device.
Levelling procedure is to be found in 'TWM4 Scale' user
manual.
7.2. START-UP
Plug the power cord to the mains.
Wait for connection to be established between the mass converter and the
„MwManager” software, read the weighing result.
The procedure of communication establishing and a detailed
description of connection between the MW-04 mass
converter and the ‘MwManager’software is to be found in
the ‘MwManager’ user manual.
