SYMBOLS
The equipment is marked with this symbol wherever the user should refer to this manual in order to avoid possible
damage. The same symbol appears in the manual at points where warnings or particularly important instructions,
essential for safe, correct operation of the device, are given.
The equipment is marked with this symbol in the areas where there is dangerous voltage. Only trained maintenance
personnel should carry out work in these areas. The same symbol appears in the manual at points where essential
safety warnings are given.
The equipment is marked with this symbol in the areas where the user must be careful to avoid crushing of hands. Only
trained maintenance personnel should carry out work in these areas. The same symbol appears in the manual at points
where essential safety warnings are given.
The equipment is marked with this symbol in the areas where the user must be careful to avoid coming into contact with
moving components. Only trained maintenance personnel should carry out work in these areas. The same symbol
appears in the manual at points where essential safety warnings are given.
The equipment is marked with this symbol in the areas where the user must be careful to avoid crushing of feet. Only
trained maintenance personnel should carry out work in these areas. The same symbol appears in the manual at points
where essential safety warnings are given.
The equipment is marked with this symbol in the areas where there is the danger of unexpected bursts of compressed
air. Only trained maintenance personnel should carry out work in these areas. The same symbol appears in the manual
at points where essential safety warnings are given.
LASER LIGHT: This symbol appears in this manual at those points where warnings or information relating to laser
pointing devices are given. Such devices may be dangerous. Do not look into the laser beam!
The equipment is marked with this symbol in those areas where insertion of hands, other body parts or objects, is not
permitted, in order to avoid system malfunctions or dangerous situations.
The equipment is marked with this symbol in the areas where it is forbidden to extinguish a fire with water.
CEIA Metal Detectors employ low intensity electromagnetic fields in compliance with current legislation.
MAGNETIC FIELDS can affect pacemakers. Persons wearing pacemakers, cardiac defibrillators and other life support
devices must not operate less than 50 cm from the opening of the Metal Detector tunnel. Wearers of pacemakers must
not operate less than 1 meter from the Metal Detectors of the THS/MN21 series which use static electromagnetic fields.
Persons wearing pacemakers who may need to approach this equipment should consult their medical practitioner
beforehand.
The equipment is marked with this symbol in those areas where it is possible to perform a ground connection.
The equipment is marked with this pictogram in those places where the user is advised to refer to this instruction manual
before any operation.
This symbol appears in the manual at points where suggestions, additional information or other relevant notes are given.

Preface
This document is the property of CEIA S.p.A. which reserves all rights. Total or partial copying,
modification and translation is forbidden.
CEIA reserves the right to make changes, at any time and without notice, to the models (including
programming), their accessories and options, and to the prices and conditions of sale.
The Metal Detector or the CEIA integrated system must be used only for the prescribed purpose and
in the ways described in this Manual. CEIA may not be held responsible for the consequences
resulting from a use other than that indicated in this Manual.
Purpose of the documentation
The complete documentation for a CEIA Metal Detector is made up of a series of Manuals, whose
purposes are listed in the following paragraphs:
Warnings manual
The safety instructions specify the safety precautions to be implemented when installing and
operating CEIA products. These instructions must be implemented throughout the life cycle of the
product.
Installation, Use and Maintenance Manual
The purpose of the Installation, Use and Maintenance Manual is to provide the information needed
for:
- installing the Metal Detector or CEIA integrated system, according to the electrical and
mechanical requirements specified by CEIA;
- configuring the Metal Detector in accordance with the type of installation and use;
- correct use of the conveyor belt system;
- correct maintenance, both ordinary and extraordinary.
Programming Manual
The purpose of the Programming Manual is to provide a description of all the items of the System
Programming Menu to:
- define the users authorized to operate the System;
- program the Metal Detector in accordance with the type of product to be inspected;
- make remote connections with the Metal Detector, using the available communication
interfaces.
Operator Manual
The purpose of the Operator Manual is to provide all the information needed by the operator for daily
use of the system.
Options, Accessories and Spare Parts List
The purpose of this document is to provide a quick consultation table for ordering any spare parts,
options and accessories.

2DESCRIPTION
2.1 General description
CEIA THS inspection systems detect metals with high detection sensitivity, for industrial use in
inspecting food or other compatible products (see paragraph 2.1.3). They are available in two
versions:
- Metal Detector: Detection Probe with power supply unit
- Integrated system: Metal Detector integrated on a conveyor belt system
2.1.1 Metal Detector
This system is designed for installation on a production line suitably set up by the customer or the
installer. It consists of a Detection Probe and a Power Supply Unit only.
The Detection Probe generates an electromagnetic field and receive, at the same time, a signal
produced by the variation of the field itself, upon interaction with metal fragments, contained in the
product to be inspected, in transit through the tunnel.
Some products, according to their own chemical-phisical characteristics, may presents magnetic and
/ or electrical properties such as to also interact with the generated field, determining a signal called
“product effect”: in this case, the Metal Detector allow to perform an automatic procedure to record
the product characteristics, in order to minimize the effect and, at the same time, to set the optimal
threshold for the discrimination of the signal due to metal, with the consequential signals to all devices
connected to the Metal Detector.
The level of a signal produced by a metallic fragment depends on the metal kind, on its dimensions
and volume, and may vary according to its orientation during the transit through the tunnel: therefore
CEIA, according to the model and to the product type, supply proper metallic samples which the
spherical geometry and type are certified to guarantee the maximum repeatibility on Metal Detector
performance evaluation.
All models are available in two different subclasses, the 21E Series and the 21 Series, with different
features and characteristics, as stated below:
