maintenance on the device. Keep the manual in a safe place for future
reference, and in perfect condition. This manual must accompany the
device described therein in the case of change of ownership, and until
the device is broken up.
The functions accessible to users and behaviour of the system, may
differ from what described in this manual, according to the settings
made. Contact the system administrator for any questions.
1.1.1 - General warnings
This equipment complies with the directive 2004/108/EC for industrial•
applications.
All personnel operating with or performing operations on the device must•
have an adequate preparation and shall know the procedures described in
this manual.
Follow the instructions contained in this manual for all operations relating•
to installation, use and maintenance of the device. CEIA cannot be held
responsible for any damage resulting from procedures which are not
expressly indicated in this manual, or from any lack of attention, either
partial or total, of the procedures described therein.
This manual must accompany the device described therein in the case of•
change of ownership, and until the device is broken up.
1.1.2 - Use warnings
If the device is stored for a long period in temperatures outside the•
operating range, wait for the temperature of the detector to come back
within that range before switching on.
Wheneverthereisanysuggestionthatthelevelofprotectionhasbeenreduced,•
the device should be taken out of service and secured against any possibility
of unintentional use, and authorised service technicians should be called.
The level of protection is considered to have been reduced when:
the device shows visible signs of wear and tear, especially on parts that ensures-
the device protections (boxes, gaskets, glands, fixing screws, etc.);
the Power Supply Box is not correctly closed;-
the ground connections are not compliant;-
the device has suffered mechanical or electrical stress (shocks, bumps, etc..);-

1.2 – Correct and Forbidden use of the device
1.2.1 – Correct use of the device
The THS/21 Metal Detector is an electronic device for the detection of•
metal masses (magnetic and non-magnetic metals) transiting inside the
detection antenna (only magnetic for THS/MN21 model).
Handle the device with care and without excessive force during installation,•
use and maintenance.
The final user is responsible for selecting the appropriate sensitivity for•
their application. After this selection has been made, and programming
has been adjusted accordingly, it is also the final user’s responsibility to
verify calibration using the test object(s) appropriate to the level of security
selected. Additionally, this test should be carried out periodically to ensure
no changes have occurred in the equipment.
The device is fitted with mechanical and electronic protections, described•
in this manual. Removing or reducing these protections is forbidden.
1.2.2 – Forbidden use of the device
The THS/21 Metal Detectors are not suitable to be installed or used in•
environments where could be present, even accidentally, an explosive
atmoshpere.
Electric arc welding shall not be carried out on the detector antenna, on•
the Control Power Box or on any part of the attached structure.

1.3 – Residual risks
Before any movement of the detector, take care about the facts that it•
could be heavy to be handled by only one person. Establish and implement
adequate procedures to perform thi s operation. CEIA cannot be held
responsible for any damage resulting from incorrect procedures.
After the maintenance of devices provided with conveyor belt, make sure•
not to leave any tool (such as screwdrivers) on the belt since they can be
hurled on switching the device on.
Before starting the system, ensure that no one else is working on the•
machine.

2.1.2 - Control Power Box
The Power Supply Box is housed in a watertight box in stainless steel which
is designed to be attached by means of four screws and through which
pass the connecting cables. The power supply unit is available in three
versions:
Control Power Box, containing the metal detector
power supply section and designed to allow connection
of external sensors and slave devices.
Conveyor Control System, with the same functions
as the Control Power Box, but with the addition of a
conveyor belt motor driver/control section.

2.2 – Safety devices and warning labels
The THS/21 Metal Detector is fitted with a list of safety features described
below, in order to warrant the proper protection level, during the correct
use.
IP Protection Degree
All the containers of the system (antenna and supply box) have a protection
degree of IP66 - IP69K. This means that they are strongly watertight during
operations and cleaning.
Cable Glands
In order to ensure the protection degree, it’s mandatory to use cables
with characteristics and diameter compliant with the device glands and
following the guidelines written in this manual. Insert only one cable for
each gland and take care that all of them are streighted in the correct way.
Do not remove the caps from unused glands.
Self diagnosis system
An internal self diagnosis system checks constantly the Metal Detector
functionality. In case of fault a message is shown on the control display
and all alarm indicators are activated together with corresponding relays.
Password
The access to Metal Detector parameters is protected by passwords.

Before starting to use the device, read carefully the Safety instructions
- Warnings section of this manual.
3.1 – Switching on the Metal Detector
It is strictly forbidden to start up the system if all safety features are
not properly functional. Tampering with the safety features is also
forbidden, and voids all responsibility of the manufacturer for any
damage caused.
On the Conveyor Control System model, the ON/
OFF switch is located on the power supply unit
cover.
In the case of the Control Power Box, an external
switch must be provided.

The presence of mains power supply is signalled by the lighting up of the
indicator located on the control panel.
When the device is turned on, the display lights up, as do the indicators
located on the front of the electronics unit.

is displayed:
The first line identifies the model (THS/21 in this case).
The second line identifies the software
version of the Metal Detector.
These first two rows, and subsequent, are
replaced, if necessary, with any indication for
the operator.
In the bottom part of the display there is a bargraph about the signal read
by the antenna. The last line indicates the type of programming, specific to
one product (in this case PROD01).
3.1.2 – Signals given during normal use
On models where there is a control panel on both the probe and the
power supply unit (because the probe is installed in a position which
is inaccessible to the operator), the electronics unit display is disabled
(the message “Disabled” appears).
Indication of the received signal
On the fourth line of the display the signal being received is displayed by
means of a horizontal illuminating bar.
When the signal increases, the bar extends towards the right. The alarm
threshold corresponds to the middle of the bar: the sections on the left are
vertical bars, those on the right are represented with a white area.
Signal well below the threshold level Signal just below the threshold level
Signal above the threshold level (alarm) After the alarm, the maximum
signal is visualized for a few seconds
together with its amplitude in dB

3.4 – Use of the device
3.4.1 – Sensitivity check with reference sample
It is important to check proper operation (sensitivity and ejection of
material) of the metal detector periodically by carrying out a sensitivity test
with a reference sample.
See paragraph 4.7.1 for the procedure.
3.4.2 – Normal use
Starting/stopping the conveyor belt
With the correct power supply and with the motor stopped, check that the
LED indicators are ON or OFF as shown in the following table:
Indicator Status
Mains voltage ON
Motor on OFF
Motor malfunction OFF
Press the start button• to switch on the motor: check that it starts up,
and that the “motor on” indicator comes on.
To stop the motor press the stop button• again: check that it stops, and
that the “motor on” indicator goes off.
Adjustment of the belt speed
The motor speed control keys have different functions according to the
value of parameter MM (see Programming section).
The speed of the conveyor belt can be adjusted by:
programming the BS parameter on the Metal Detector-
simply pushing the keys located on the Conveyor Control System, if parameter-
MM=OFF and the parameter UD=ON.
During programming of the Metal Detector, the Conveyor Control
System UP and DOWN keys are disabled.
While the Conveyor Control System keys are being used, Metal
Detector programming is disabled
