The equipment that you have just bought was designed, manufactured
and tested in accordance with the essential safety requirements of the
European Directives ATEX 94/9/EC (until April 19
th
, 2016) and 2014/34/EU
(from April 20
th
, 2016).
Read these instructions carefully BEFORE installing, using or maintaining
this equipment.
Products intended for installation in a potentially explosive gas or
combustible dust atmosphere must:
a)
Be installed, put into service and maintained in compliance with
national and local regulations and in accordance with the
recommendations contained in the relevant standards concerning
potentially explosive atmospheres.
b)
Be installed, put into service and maintained by qualified and
competent professionals who have undergone suitable training for
instrumentation used in potentially explosive atmospheres.
Under certain operating conditions, the use of damaged instruments could
cause a degradation of the performances of the system, which may lead
to personal injury or death.
Use only genuine spare parts, which are provided by the manufacturer, to
guarantee that the products comply with the essential safety requirements
of the European Directives mentioned above.

INSTALLATION
Before proceeding with installation:
♦
Carefully unpack the equipment and check it is not damaged. In the
case of any damage, notify the manufacturer.
♦
Check the compatibility of the equipment with the installation zone
(Directive 99/92/EC).
♦
Check that the maximum temperature of the fluid passing through the
level does not exceed the maximum surface temperature of the
temperature class T1 to T6 in the zone where the equipment is
installed and the limits of the manufacturer (see catalogues available
on our Internet site at
♦
Check the maximum ambient temperature will never exceed the
maximum permitted ambient temperature indicated on the
manufacturer's label of each instrument mounted on the level. without
ever exc74°C.
♦
For specific conditions of use, user shall also consult the ATEX
Instruction Manual (GEA19100) related to the digital level instrument
head.
♦
Check the minimum ambient temperature will never be below -50°C.
♦
Comply with the heat insulation instructions recommended by the
manufacturer.
Carry out the pneumatic and electrical connections of instruments after
checking that local conditions so allow. All instructions necessary for
correct and safe installation of instruments are available in the specific
ATEX instructions attached to the instruments. These instructions can also
be accessed on our Internet site
In particular:
♦
Ensure the installation complies with the applicable regulations and
the standards, and observe the instrument safety parameters.
♦
Connect the level and electrical instruments to the ground.
♦
Respect the polarities of the electrical connection.
♦
Use cable entries that comply with ATEX regulation and are suitable
for the zone and the protection mode of the instrument.
START-UP
Before putting the level into service, check that all the equipment is
correctly connected, grounded and the safety covers and screws are in
place.
USE
Use the level within the temperature limits recommended by the
manufacturer (see paragraph on installation).
♦
Do not use the level for any application other than that initially
specified.
♦
Regularly check there is no fluid leakage in particular at the gaskets.
♦
Respect the instructions for use of electrical apparatus.
♦
Avoid any impact on the aluminum alloy housing (extension, double
case 12800).
♦
Do not rub plastic covers of the instrument; this could cause a risk of
electrostatic discharge which could lead to an explosion.
♦
Ensure the fluid does not carry particles likely to create a spark if the
inside of the level could be considered as an ATEX zone.
MAINTENANCE
Before carrying out maintenance work, ensure local conditions are suitable
for the operations: Make sure that suitable safety equipment and
protection devices are available, taking into account the nature of the
operations and the zone where they are to be performed.
♦
Carry out the maintenance operations in compliance with the specific
instructions for the product concerned.
♦
Use only genuine spare parts, from the manufacturer.
♦
Remove deposits of combustible dust which may form on any exposed
surfaces.
♦
To avoid the production of sparks due to electrostatic discharges, it
will be advisable to follow the instructions of the code of practice EN
TR50404. For example, the user will proceed to the cleaning of the
device, and in particular the plastic label, by means of a wet rag. For
safety reasons, this operation can be performed only when the local
conditions are not potentially explosive.
Surveillance of equipment in potentially explosive atmospheres
: comply
with the regulations in force (Directive 99/92/EC).
