2. SECURITY REQUIREMENTS

Please read this manual carefully prior the first usage. Following the
instruction, use the device as intended;

PUE C/31H/EX indicator, and scales with design based on the indicator,
can be used in explosive z one 1 and 2 where ther e is a mixtures of gases,
vapours and mists of II (second) explosion group and T1, T2, T3 or T4
temperature class.
WPT………/EX and W T C………/EX s cales, b ecaus e of the constr uction of
non-electric part of the platf orm and used materials, can be operated in 1
and 2 zone where t here are mixtures of gases , vapours and mists of IIA,
IIB, or IIC group – according to „Technical Documentation” of the scale.

Anti-explosive safety of the PUE C/31H/EX indicator, and of scales
with design based on the indicator is assured by:

• Power supplied from the ZRi02 power supplier II (2) G [Ex
ib] IIC KDB 06ATEX251 manufactured b y RADWAG, placed
behind the hazardous area or from another adapter with
appropriate parameters of intrinsically safe electrical circuit.

• Intrinsically safe design of PUE C/31H/EX indicator complying
with:
EN 60079-0 and EN 60079-11 standards, confirmed by
KDB 06ATEX250 certificate

• Using load cells certified for conformity with ATEX directive (on
anti-explosion safety)

• Making non-electric parts pf the scale in compliance with EN
13463-1 standard

• Observing recommendations in this manual by users

- marking of paragraphs crucial for anti-explosion safety

3. START-UP

Please read this manual carefully prior the start-up. Following the
instruction, use the device as intended.

3.1. Scale placing

• The scale should be unpacked outside the hazardous area.

• Before moving the scale to the place of operation prepare a cable

for earthing the device against electrostatic charges.

NOTICE!!
In order to protect the indicator against gathering electrostatic
charge it is necessary to earth/zero its housing.
Connect the earthing lead/wire to cable connection points

marked with „

• Situate scales and an indicat or in hazardous area and connect
earthing/zeroing.

EXI-01-04-06-14-GB

Mounting the indicator, placing the weighing platform and
earthing/zeroing should be performed when the explosive
atmosphere cannot appear.

Indicators with cable can be mounted on the rack, on the wall or on
the table using a special mounting kit.
Weighing platform should be placed on even and stable ground far
from sources of hit and draughts. It should be also levelled out
using the feet.

3.2. Connecting power supplier

1. Place the power supplier outside the hazardous area.

2. Connect the plug that terminates the supply cable (up to 20m) to
the socket marked as DC IN.

3. Connect the supplier to mains (230V AC).

4. In case of not using the scale unplug it from the mains.

NOTICE!

Scales with PUE C/31H/EX indicators can be supplie d o n ly
from ZRi02 power suppliers

II (2) G [Ex ib] IIC KDB
06ATEX251 of RADWAG production, placed outside the

3.3. Switching on

• Press the ON/OFF key – keep pressing for about 1 sec.

• After switching on, wait for the test completion.

• The indication shall equal zero and the following pictograms shall be

seen:

- zero indication

- equilibrium

kg - weighing mode

• If the indication does not equal zero press the zeroi ng key

.

Ready to use.

4. CLEANING

Cleaning can be performed only after unplugging from mains (230V AC). Use agents and
materials that do not cause gathering electrostatic charges on elements of the scale!

Do not use abrasive agents and solvents because
it can cause damage of the casing.

Cleaning should be performed when the appearance of explosive
gases is impossible

5. SERVICE AND REPAIRING

EXI-01-04-06-14-GB

- 15 -

In case of any problems with appropriate operation of the indicator, contact
the manufacturer’s service centre or any service centre authorised by
RADWAG.
In case of any fault or dysfunction the device should be passed to the
manufacturer’s s ervice centre or, if this is not possible, the fault should be
reported in order to settle the conditions of repair.

Any intrusion (alteration, repair etc.) in the indicator or scale
based on PUE C/31H/EX indicator, by unauthorised persons
will cause a forfeiture of validity of certificates, declarations
and manufacturer’s warranty.

6. FUNCTIONS

• Filtering

• Autozero

• Minimal mass

• Counting pieces

• +/- control

• Deviation in per cents

• Peak hold

• Automatic tare

• Tare memory

• Manual tare inscription

• User’s calibration

• Totalizing

It is possible to disable selected functions thus making the scales adjusted
to one’s own needs. Access may be permitted to some particular functions
only if required. The user menu allows enabling/disabling a given
parameter, see the further part of the manual.
