1 GENERAL
1.1 LIMITS OF USE AND PRECAUTIONS FOR SAFETY
In order to guarantee safety of the operator together with the correct functioning of the equipment, it is
important to work within the limits permitted and to adopt all of the precautions listed below:
CAUTION
Check before use to make sure that all safety requirements are fully satisfied. The
equipment must not be powered or connected to other equipment until safety
conditions are satisfied.
1.1.1 ELECTRICAL SAFETY
CAUTION
All the connections should be isolated from the environment ground (mass is not
isolated).
DO NOT connect any of these connections to earth.
In order to guarantee conditions of utmost safety for the operator, we recommend that all of the indications
listed in this manual are respected.
• Power the equipment exclusively using network tension according to specifications
(100 ÷ 240 Vac/dc 50-60 Hz)
• Replace damaged parts immediately. Cables, connectors, accessories or other parts of
the equipment that may be damaged or not working correctly must be replaced
immediately. In this case contact your nearest authorized technical assistance center.
• According to UL, do not connect to relay outputs a voltage exceeding 115V
1.2 CAUTION SYMBOL
The symbol illustrated below represents the CAUTION symbol and reminds the operator that he should
read the user manual for important information, advice and suggestions for the correct and safe use of the
equipment.
This symbol is also used within the software, in particular in the “measures” screen, putting attention to an
event which will be explained in the following page of the screen.
In particular, when it is positioned close to connection points to cables and peripheries, the symbol in
question refers to careful reading of the user manual for instructions related to the nature of such cables
and peripheries and the methods for correct and safe connections.
The reproductions of equipment panels, with relative commands, connections, symbols and labels are
provided in this chapter. Each caution symbol is accompanied by a detailed explanation of its meaning.
1.2.1 SPECIAL ATTENTION TO CRITICAL COMPONENTS
The instrument is fitted with an LCD liquid crystal display, which contains small amounts of toxic materials.

Astralpool multiparameter
USER MANUAL
0000138319 Rev. 3.2 5
1.2.2 SAFETY OF THE OPERATIVE ENVIROMENT
The panel is protected against the introduction of liquids. Avoid subject the equipment to the risk of dripping
water, sprays of water or immersion in water and the use in environments in which such risks may be
present. Equipment in which liquids may have accidentally penetrated must be immediately switched off,
cleaned and controlled by authorized and qualified personnel.
Once programming has been carried out, we recommend that the transparent panel is closed.
Protection:
- with a closed transparent panel IP65 EN60529
- with an open transparent panel IP54
- EMI /RFI CEI EN55011 - 05/99
- Use the equipment within the environmental limits of temperature, humidity and pressure
specified.
The instrument has been developed to operate in the following environmental conditions:
- Temperature of the working environment: 0°C ÷ +50°C
- Temperature of storage and transportation: -10°C ÷ +50°C
- Relative humidity: 10% ÷ 95%RH – not condensing
CAUTION
The water treatment plant in which the instrument is introduced must be developed in
accordance with the functional requirements imposed by current legislation.
The apparatus must be inserted perfectly into the plant.
The plant must be kept operative in full compliance with the safety regulations provided.
The parameters indicated on the control gear case of the analyzer must comply with
current regulations.
Any signals of faults to the device must be positioned in an environment that is
constantly controlled by operative personnel or plant assistants.
Non-compliance with even just one of these conditions may lead the “logics” of the
device to operate in a potentially dangerous manner for users of the service.
Therefore, we recommend that service personnel and/or maintenance personnel
operate with the utmost care, pointing out any changes to the safety parameters
immediately, in order to avoid the creation of any potentially dangerous situations.
As the considerations indicated above cannot be controlled by the product in question,
the manufacturer will not be held responsible for any damages that these malfunctions
may cause to people or things.

• The card uses an EEPROM to store the Set-up data and flash memories for storage of the archives
of historical data and LOG files of events.
• The Card has 1 RS485 gate (opto-isolated) for local networks used for connections with local
communication devices (configuration computer, terminals and remote controls etc).
• The card integrates a Real Time Clock (clock with date) that allows the software to store figures in
a chronological order.
