1.3 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

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 authorised technical
assistance centre.
•Only use accessories and peripheries specified by CHEMITEC. In order to
guarantee all of the safety requirements, it is important to make exclusive use of the
accessories specified in this manual which have been tested in combination with the
equipment. The use of accessories and consumption materials of other
manufacturers or not specifically recommended by CHEMITEC will not guarantee the
safety and correct operation of the equipment. Only use peripherals that comply with
the regulations of their specific categories.
•According to UL, not connect to relay outputs a voltage exceeding 115V
1.3.2 SAFETY OF THE OPERATIVE ENVIRONMENT
•The panel of the 50 Series device 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 authorised and qualified personnel.
•Protection.
50 Series Wall mounting
−IP66 EN60529
−EMI /RFI CEI EN55011 - 05/99
−CLASS II INSTRUMENT REQUIRES NO GROUND CONNECTIONS
•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 -20°C ÷ +65°C
−Temperature of storage and transportation -25°C ÷ +65°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 parameters indicated on the analyser 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.

1.6 PLATE DETAILS
1.7 INFORMATION ON RECYCLING AND USE OF MATERIALS
CHEMITEC, in accordance with specific European regulations, aims at constant
improvement of development and of production procedures of its equipment with the
objective of drastically reducing the negative impact on the environment caused by parts,
components, consumption materials, packaging and the equipment itself at the end of its
life cycle.
Packaging is conceived and produced to allow for its re-use or recovery, including
recycling of the majority of the materials and to reduce the amount of waste or residues to
be disposed of, to a very minimum. In order to assure a correct environmental impact the
equipment has been designed with the smallest circuit possible, with the lowest
differentiation possible of materials and components, with a selection of substances that
guarantee utmost recycling and maximum reuse of the parts and waste disposal free from
ecological risks.

The equipment is made in such a way as to guarantee the easy separation or dismantling
of the materials containing contaminants compared with others, in particular during
maintenance operations and the replacement of parts.
CAUTION
The disposal/recycling of packaging, of consumption materials and of the
equipment itself at the end of its life cycle must be carried out in accordance
with the norms and regulations that are currently valid in the country in
which the equipment is used.
1.7.1 SPECIAL ATTENTION TO CRITICAL COMPONENTS

Main hardware characteristics of the electronic device
The hardware structure of this periphery is based on the adoption of extremely new CPU
CMOS with 8 bits developed specifically for the execution of the so-called “embedded”
applications.
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 storage
figures in a chronological order.
The device has been designed to be fitted onto a panel, and is built with an IP66
protection enclosure.

instrument.
Apply a tension alternating between 100Vac and 240Vac 50/60 Hz or, according to
details on the identification plate, the most stabilised tension possible.
Avoid at all costs connections to power supplies that have been rebuilt, for example, with
the help of transformers in which this rebuilt power supply will feed other systems beyond
the device (perhaps of an inductive kind) because, in this way, high tension spikes will be
created and once they are irradiated it becomes very difficult to block and/or eliminate
them.
Connect the instrument to the power line by using a 2-pole cable with double PVC sheath,
copper section min 1mm2

CAUTION
The electric line must be fitted with a suitable life-saving device and
magneto-thermal, in compliance with correct installation norms.
The supply disconnecting device must be easily accessible after installing
the instrument and must be marked as the disconnection of the unit.
In any case it is always best to check the quality of the Ground connection. It is very
common to find Ground connections, mainly in industrial environments, that are
generators themselves of disturbances: in the case of any doubts on quality a connection
to a rod dedicated to the device plant is recommended.
3.1.3.1 Electrical Connections to the dosage systems (Users)
CAUTION
Before starting connections between the Device and the external Users,
make sure that the electrical panel is switched off and the cables from the
Users are not under tension.
“Users” mean the outlets and relays used in the device
−(SET1) for the Dosage Pump or control command
−(SET2) for the Dosage Pump or control command
−(SET3) for the Dosage Pump or control command
−(SET4) for the Dosage Pump or control command
−(SET5ALARM) the alarm command transmitted by the instrument to the siren
and/or flashing light
−(SET6WASH) electrode washing command
CAUTION
Each relay contact can support, on a resistive load, a maximum current of 1
Ampere with a max. of 230V, therefore a total power of 230VA
In the case of higher levels of power it is best to carry out connections as indicated in the
layout of fig. 6-b)
If the load to be handed is of low power or of a resistive nature, the layout indicated in Fig.
6-a) can be used.
