PRECAUTIONS
Prior to installation, use or maintenance activities, carefully read this user
manual and follow the provided guidelines.
Prior to the first use, carefully read this user manual. Use the weighing
device only as intended.
Place weighed loads in the centre of the weighing pan.
Load the weighing pan with loads of gross weight which does not exceed
the maximum capacity.
Mind not to leave heavy loads on the weighing pan for longer periods
of time.
Protect the indicator against considerable temperature variation, solar and
UV radiation, substances causing chemical reactions.
The HX7 indicator must not be operated in hazardous areas endangered
with explosion of gases, and in dusty environments.
In case of damage, immediately unplug the device from the mains.
Scales to be decommissioned must be decommissioned in accordance
with valid legal regulations.
Do not let battery discharge in case of prolonged storage of the device
in low temperature.
A worn out battery can be replaced only by the manufacturer or by the
authorized service.
Accumulators do not belong to regular household waste. The European
legislation requires discharged accumulators to be collected and disposed
separately from other communal waste with the aim of being recycled.
Symbols on batteries identify harmful compounds: Pb = lead,
Cd = cadmium, Hg = mercury. Dear user, you are obliged to dispose of the
worn out batteries as regulated.
If the scale 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 scales are a response to growing market demands for a solution offering
simplicity of operation and weighing process automated to the maximum. Due
to use of a multifunctional PUE HX7.EX indicator, the scales are a perfect
solution for numerous industry applications. The PUE HX7 indicator is
equipped with a stainless steel housing of high IP. The PUE HX7 features 7’’
colour display guaranteeing perfect readability, and diode bar graph visualising
MIN, MAX thresholds. It is operated using 22-key membrane keypad equipped
with programmable function keys.
A scale of standard design offers RS232, USB type A, Ethernet, 4 I/O.
Optionally it can be equipped with an internal battery, this allows its operation
in places where there is no access to the mains. The device integrates with
receipt and label printers, barcode scanners and PC accessories (mouse,
keyboard, USB flash drive).
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 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 an authorized service point,
service claims intrusion into mechanical or electronic construction by
unauthorized people,
the scale 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 warranty certificate.
H. Contact with the central authorized service: [phone].

3.MAINTENANCE ACTIVITIES
In order to ensure safety in the course of cleaning, it is necessary to disconnect
the device from the mains. With this condition met, uninstall the weighing pan
and other detachable components.
Cleaning the weighing pan while still installed may cause
damage of the measuring system.
3.1. Cleaning Stainless Steel Components
Avoid cleansers containing any corrosive chemicals, e.g. bleach (including
chlorine). Do not use cleansers containing abrasive substances. Always
remove the dirt using microfiber cloth to avoid damage of protective coating.
In 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.
3.2. Cleaning ABS Components
To clean dry surfaces and avoid smudging, use clean non-colouring cloths
made of cellulose or cotton. You can use a solution of water and detergent
(soap, dishwashing detergent, glass cleaner). Gently rub the cleaned surface
and let it dry. Repeat the cleaning process if needed.
In the case of hard to remove contamination, e.g. residues of adhesive, rubber,
resin, polyurethane foam etc., you can use a special cleaning agents based on
a mixture of aliphatic hydrocarbons that do not dissolve plastics. Before using
the cleanser for all surfaces we recommend carrying out tests. Do not use
cleansers containing abrasive substances.
3.3. Cleaning Platform Scales for Meat Industry
Platforms of meat industry scales are made of stainless steel (0H18N9 by PN,
1.4301 by EN, 304 by AISI) and silicone components.
Exceptions are zink-plated track scales made of galvanized steel and powder-
coated livestock scales with aluminium insert placed on the weighing pan.
Cleaning and disinfecting agents must be properly selected
with regard to the scale.
In case of livestock scales, for commercial purposes it is necessary to use only
stainless steel solutions.

These are much more resistant to long-lasting harsh conditions typical for
slaughterhouses and livestock purchase sites. Powder-coated livestock scales
can be used for rare small volume production, they must be stored clean in dry
storage area and can be washed using water with a detergent. Do not use any
agents or cleansers that are not intended to come into contact with skin (i.e.
requiring use of protecting gloves).
In case of track scales it is forbidden to use chemicals containing penetrating
substances. Grease and impurities accumulating in places where the scale
track touches the line track must be cleaned off periodically.
Weighing indicators of all scales feature stainless steel housings, polyester
overlay and polyamide glands. Platforms of both livestock and ramp scales,
their load-bearing structures and weighing tracks can be water-jet cleaned, the
water temperature must be up to +80°C, respective cleanser needs to be
added. When it comes to indicators, it is forbidden to apply water-jet cleaning
method, use of hot water is not allowed. It is recommended to cover the
indicators for the time of pressure washing of the surroundings.
While cleaning platforms and indicators of waterproof platform scales do not
use either intense water jet or hot water, this is to avoid damage of silicone
bellow of platform sensor cover and indicator's operation panel or glands.
Platforms of platform scales can be water-jet cleaned when uninstalled, they
can also be cleaned by immersion into water.

4. SERVICE AND REPAIR
In 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 case of any problems with correct operation of the scale, contact the closest
manufacturer's service point.
In 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 scale
modification, repair etc., by unauthorized persons, will result
with loss of validity of manufacturer-issued certificates,
declarations and warranty.
5. RECYCLING
HX7 scales must be recycled, they are not to be treated as a regular household
waste. Scales to be decommissioned must be decommissioned in accordance
with valid legal regulations.

6. MECHANICAL DESIGN
6.1. 1-Load-Cell Scales
1-load-cell HX7 scale is intended to carry out fast and precise mass
measurement of up to 300 kg loads. Its characteristic feature is a platform with
one load cell only. The platform is equipped with a stainless steel weighing
pan. Depending on a scale model, the cross and base are made of either
stainless steel or powder-coated steel.
