PRECAUTIONS
Prior to installation, use or maintenance activities, carefully read this user
manual. Use the PUE C32 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 PUE C32 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
The PUE C32 weighing indicator is a part of construction of industrial scales
operating on the basis of load cells. The indicator features an ABS plastic
housing and a 5'' colour graphic display ensuring perfect readability. It is
operated using 22-key membrane keypad equipped with programmable
function keys.
Standard design offers two RS232 interfaces, USB type A, USB type B,
Ethernet, wireless communication, 2 proximity sensors, 4 I/O. The indicator can
be operated in areas where there is no access to the mains. It can optionally be
supplied by NiMH battery (nickel-metal-hydride) of 1800 - 2800 mAh capacity.
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.
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.

6
Cleaning the weighing pan while still installed may cause
damage of the measuring system.
3.1. 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.
3.2. Cleaning Stainless Steel Components
Avoid using cleansers containing any corrosive chemicals, e.g. bleach
(containing chlorine). Do not use cleansers containing abrasive substances.
Always remove the dirt using microfiber cloth to avoid damage of protective
coating. 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.

5.INDICATOR INSTALLATION
5.1. Unpacking and Installation
A. Take the indicator out of the packaging.
B. Connect the indicator to a weighing platform, next place the weighing
device on a flat and even surface. Keep it far away from any sources of
heat.
C. To level the weighing instrument turn its feet. Keep turning the feet until
the air bubble takes central position:

11
5.2. Start-Up
The indicator can be connected to the mains only with a power supply that
comes standard with the particular model. Nominal voltage of the power supply
(specified on the power supply data plate) has to be compatible with the mains
nominal voltage.
Procedure:
Connect the power supply to the mains. Plug it to the power supply socket
that is located on the scale's side.
Press key, it is to be found at the top of the operation panel.
Upon completed start-up, the home screen is displayed automatically.
5.3. Battery Status
Optional scale design features an internal battery. pictogram, displayed
at the top of the screen, either signals battery status or informs that battery
charging is in progress:
pictogram displayed in a cyclic manner: battery charging.
pictogram displayed continuously: battery charged within 75% -
100% range of permissible voltage,
pictogram displayed continuously: battery charged within 50% - 75%
range of permissible voltage,
pictogram displayed continuously: battery charged within 25% - 50%
range of permissible voltage,
pictogram displayed continuously: battery discharged (charge level
below 25% of the permissible voltage), connect the scale to the mains in
order to charge it,
blinking pictogram: damaged battery or battery lack,
no pictogram: scale not equipped with the battery.
Battery discharge is signalled by the following message:
<Excessively discharged battery. Scale shutdown is to
occur>. Upon scale shutdown, connect it to the mains in
order to charge the battery.
