PRECAUTIONS
Prior to installation, use or maintenance activities, carefully read this user
manual. Use the PUE HX7 Indicator only as intended.
Prior to the first use, carefully read this user manual. Use the device only
as intended.
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.

1. INTENDED USE
PUE HX7 weighing indicator is a device intended to make industrial scales
operating on the basis of load cells. It is equipped with a stainless steel housing
of high IP. The PUE HX7 features 7’’ colour display guaranteeing perfect
readability, and a diode bar graph visualising MIN, MAX thresholds. It is
operated using 22-key membrane keypad equipped with programmable
function keys.
PUE HX7 indicator of standard design offers RS232, USB type A, Ethernet,
4 I/O interfaces. 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 RADWAG 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.

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 using cleansers containing any corrosive chemicals, e.g. bleach
(containing chlorine). Do not use cleansers containing abrasive substances.
In order to avoid damage of protective coating always remove the dirt using
microfiber cloth.
Daily cleaning routine (removal of small stains):
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.
