II- INSTALACIÓN

Instrucciones ESTE MANUAL HA DE SER LEIDO POR LAS SIGUIENTES PERSONAS:

- EL DUEÑO - EL OPERADOR - EL TÉCNICO DE MANTENIMIENTO

Lee este manual antes de instalar, operar o llevar a cabo el mantenimiento del dispositivo. Guarda el manual en un lugar seguro y en perfectas condiciones para consultas en el futuro. Este manual debe acompañar al dispositivo descrito ahí en caso cambie de dueño, o el dispositivo se descom-ponga. • 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 .

• Whenever there is any suggestion that the level of pro-tection has been reduced, 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; - the device does not operate correctly; - the device has been stored for long periods in suboptimal conditions; - the device has suffered severe stress during transport; - the device has come into contact with liquids.

• 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 peri-odically to insure no changes have occurred in the equipment.

• Handle the device with care and without excessive force during installation, use and maintenance.

• After installation the device should be stable, and not subject to vibration or accidental movement. All con-necting cables should be properly fastened down, in order to avoid knocks and accidental damage and to obtain optimum performance.

• Position the device as far as possible from sources of electromagnetic interference, such as transformers or motors.

• Before connecting the device to the power supply, ensure that the power supply voltage corresponds to that indicated on the plate affixed to the device. The device should be connected to the mains voltage only after all connections required for full installation have been carried out.

• The device must be connected to a power supply circuit fitted with a switch or other device which allows the power to be cut off.

• Ensure that replacement fuses are of the correct rating and of the prescribed type. Makeshift fuses and short-circuiting of the fuse boards are strictly forbidden.

• If the device is to be powered via an external autotrans-former to regulate the voltage, ensure that the common terminal of the autotransformer is connected to the neutral of the power-supply circuit.

• The power-supply plug must only be inserted into a socket fitted with an earth/ground connection. Any break in the safety conductor, either inside or outside the device, or disconnection of the earth/ground safety terminal, will render the device dangerous. Intentional cutting or disconnection is strictly forbidden.

• To avoid damage due to lightning, disconnect the power-supply cable during storms.

• This device contains electrical and electronic components, and may therefore be susceptible to fire. Do not install in explosive atmosphere or in contact with inflammable material, Do not use water or foam in the case of fire when the device is powered up.

• The device must be disconnected from all power sources before undergoing any maintenance or cleaning, and before being moved.

• Do not wash the device with liquid detergents or chemical sub-stances. Any cleaning should be done using a slightly-damp, non-abrasive cloth.

• Read the chapter on “Maintenance” carefully before calling the service centre. Whatever the problem, only specialised service personnel authorised to work with CEIA equipment should be called.

• Any damaged parts of the device should be replaced with original components only.

• Any maintenance or repair of the device while open and energised should be avoided, and in any case should only be carried out by trained personnel who are fully aware of the risks which the operation entails, following the instructions given in the “Maintenance” section.

• Disposal of parts with environmental impact: follow the regulations in force in the country where the device is being used (refer to the “Maintenance” section).

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.

Warranty conditions The Warranty on all CEIA equipment relates to goods delivered from our factory, under our general and specific conditions of sale.

Power-supply and control unit The power-supply and control unit 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 two 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

Control Power Box

Fig. I-3a - Control Power Box in stainless steel casing

Fig. I-3b – Internal view of the ALM card

Fig. I-3c - Control Power Box with RCU remote control panel (model

THS/G or other models on request) The module contains only the electronics needed for supplying power to the probe and the connection terminals for external sensors and slave devices. The card inside (card ALM), allows connections to be made to the following:

• metal detector probe • mains power supply • product transit photocell • external activators and sensors • personal computer

Fig. I-4 Control Power Box: rear and side views


Conveyor Control System In addition to the functions provided by the Control Power Box, this includes a module to drive the conveyor belt motor. This module is available in two versions:

• Card MDT, for fixed-speed applications; in this case, a three-phase input power supply (230V or 400V) is required;

• Card MDL, for variable-speed applications; in this case, a single-phase input power supply is required, as the card incorporates an inverter with three-phase outputs.

The versions available, therefore, are the following:

General guidelines for mechanical installation


• Load-bearing structure

During assembly the solidity of the load-bearing structure should be borne in mind, in order to ensure that the detector does not oscillate, causing false alarms

• Metal structures surrounding the Metal Detector/conveyor belt system

Fixed metal structures All the fixed metallic structures in proximity to the detector must be securely fastened down with bolts and self-blocking nuts and, if they form intermittent loops, soldered. This is due to the fact that sporadic metallic contacts due to vibrations, resulting in the intermittent short-circuiting of the voltages induced by the probe, may lead to interference with subsequent false alarms in the device.

Fig. II-1 Fixed metal structures

THS/M Installation of structures or equipment with ferromagnetic frames in the vicinityof the Metal Detector is not recommended. If this proves unavoidable, they must be placed at least distance D from each side of the probe. Other THS models Fixed metal structures (frames, metal furniture, etc.) must, in all cases, be located at a distance that is at least equal to the height of the probe (A), on both sides of the probe.

| Model THS/M THS/A Other models |

| | | D ≥ 3 DH ≥ 2 DH ≥ DH | | |

Fig. II-2 : Fixed metal structures

Moving metal structures Such structures, especially when of a considerable mass (mills, hoppers, etc.), must be located as far away as possible from the probe.


| | | D ≥ 10 DH ≥ 10 DH ≥ 6 DH | | |

Fig. II-3 Moving metal structures

General guidelines for electrical installation Possible sources of electrical interference may be power supply cables (electromagnetic fields generated by alternating currents) or impulsive electromagnetic sources (electrical motors with high start-up absorption of power and their power supply cables, fluorescent lights, emergency generators, remote control devices, etc.) located near the probe. • Power supply cables to other devices. The route of the conductors must never be allowed to create a large-scale

electromagnetic loop. The power supply cables must be distanced as far as possible from the probe and braided with the shortest possible pitch. In general, it is advisable that the power supply cable harnesses be inserted into special insulated channels. In the event that the conductors have to pass near the probe of the metal detector, it is advisable that they be inserted into an iron tube, either electro-welded or drawn, which is at least 2 mm thick and has a suitable diameter. N.B: this solution is only valid if the tube is not subject to vibrations; should it be subject to vibrations this solution could even be counter-productive.

• Grounding. This connection must lead directly to the electrical power supply board and must not be derived from any

other electrical devices.

QE

Fig.II-4. QE: electrical board; M1: machine 1; M2: machine 2; MD: metal detector. • Warning! If metal ducts are used for production line

power and control lines, it is advisable not to create an electrical connection between the conveyor belt frame and other nearby devices through the same ducts: if this is done, interference due to multiple ground returns could be produced.

• Impulsive sources. In general, impulsive sources must be distanced or eliminated.

It is therefore recommended that, during installation, the following procedures be carried out: 1 position as far as possible from the probe any motors, electrical power boards or electromagnetic actuators (it is

recommended that they be replaced with similar pneumatic devices); position fluorescent lights and their respective reactors at a distance from the metal detector probe; where possible replace fluorescent lights with filament lights.

2 equip electrical motors with special iron screens and mains filters of sufficient capacity. It is recommended that

motors running on alternating current be used as opposed to those running on direct current. The table that follows provides some general guidelines for the distances to be placed between the probe and asynchronous motors, depending on their power.

Table II-A

Recommended minimum distance between the probe and motors with alternating current (without screening of the motor)

2.1 In the immediate proximity of the metal detector, the motors may be screened by means of cylindrical

enveloping in iron; such cylinders must have a sufficiently large diameter in order to contain the motors and a thickness of not less than 2 mm. The cylinders must be of the unwelded type.

3 fit the electromagnets, remote controls and continuous current motors with RC muffling nets (ask our technical

office for details of the dimensions) and braid the respective power supply cables with as short a pitch as possible.

Fix the cable which connects the probe to the power supply unit so that it can not oscillate or vibrate. If the cable is too long, DO NOT CUT THE CABLE: COIL UP THE EXCESS!

Electrical installation - General notes


Connect the apparatus to the mains power supply only after first carrying out all the other connections needed for complete installation.

These instructions for electrical installation apply to both the CEIA INTEGRATED THS SYSTEM, with conveyor belt, and the CEIA NON-INTEGRATED THS SYSTEM, without conveyor belt.

Connecting to the mains power supply

Only make the connections to the internal terminals of the power supply unit when the unit is disconnected from the mains

Connection to the ground

Connect a grounding conductor to the PE terminal ; the size of the conductor should be in line with the safety standards in force.

Using the I1 switch, it is possible to set the metal detector power supply voltage to 115Vac or 230Vac. In the illustration, the selector is positioned at 220-240Vac.

N.B.: the conveyor belt motor must be set up for the power supply voltage of the system: the power supply voltage should therefore be specified at the time of ordering.

If the power supply to the device is different from that specified on the plate and/or from that chosen at selector I1, permanent damage may be caused to the device. CEIA will not be held responsible for damage to people, animals or objects caused by failure to obey this instruction. Verification that the power supply conforms to the values specified above and to the regulations in force is the total responsibility of the customer.

Connection of the compressed air supply Connect any components powered by compressed air to a source which complies with the specifications in the “Technical characteristics” section, or otherwise specified in the configuration sheet enclosed with this manual.

Non-integrated THS system supplied without conveyor belt: detailed construction notes and selection of operating parameters

The following notes provide additional instructions necessary for installing the detector on a conveyor belt or other transport system set up by the customer. For the installation checks you need to be able to switch on the system, understand the signals given during use and set the applicable operating parameters. These operations are described in the first part of the “USE” section.

Mechanical Installation

Controls According to regulation EN60204-1, the main switch and the other controls to be used by the operator must be at a height ranging from 600mm to 1,800mm from the flooring. If it proves impossible to comply with this measurement due to the configuration of the system, an additional control unit which complies with the regulations must be set up.

Mechanical installation of the metal detector Mount and fix the probe onto the structure of the conveyor belt (use the four holes located on the base-plates. N.B.: on some models the base-plates can be fixed in two different positions to adapt to the shape of the load-bearing structure). The belt must pass through the tunnel.

The structure must be stable and not subject to vibrations.

Mechanical installation of the power supply unit The power supply unit must be firmly attached to the load-bearing structure by means of four screws; it must be close to the central electronics unit and to the external subsidiary devices connected to the unit (photocell, ejector, etc.).

Mechanical installation of the THS/G probe Mount the probe on the pipe carrying the material to be inspected and fix it with screws and plastic spacers, using the holes provided on underside ( see Fig. "Dimensions of the probe", dimension FHW). Fix the control unit in a convenient position for use, within the limit set by the length of the probe connecting cable.

Fix the cable which connects the probe to the power supply unit so that it can not oscillate or vibrate. If the cable is too long, DO NOT CUT THE CABLE: COIL UP THE EXCESS!

Proximity limits around the THS/G probe The distance between the probe and fixed or moving masses depends on the sensitivity selected and on the size of the masses. The figure below shows: • the minimum distance D between the probe S and the support plate P • the minimum distance H between the probe S and the deflector f, based on a sensitivity setting of 280 and a flap-

type deflector in stainless steel. If the sensitivity or the type of deflector is changed, this minimum distance may decrease: using the procedure for checking environmental interference (see “Maintenance” section), check that activation of the deflector does not influence operation of the metal detector.

Fig. II-12 – fixing the THS/G probe

THS/G : mounting the power supply unit The power supply unit must be firmly fixed to the supporting structure with four screws, near the electronics unit and the slave devices connected to the power supply unit (photocell, ejector etc.). For the location of the holes provided for fixing the unit, see Figure I-14a.


Conveyor belt

The distances quoted below are indicative only, and subject to variation according to the sensitivity required and to the type of probe. When installation has been completed, therefore, correct operation should be checked.

Load-bearing structure of the conveyor belt The load-bearing structures of the conveyor belt must be stable and not subject to detectable vibration during movement of the belt. THS/M The structure of the belt must be in non-magnetic steel (e.g. non-magnetic AISI 304).

Fig. II-13 Load-bearing structure Rollers of the conveyor belt

In general, it is advisable that any rollers located near the antenna be of insulating material. In which case, there must be an electrical connection on only one side of the roller, in order to allow the discharge of any electrostatic charges. | Model THS/M THS/A Other models |

| | | D ≥ 3 DH * ≥ 3 DH * ≥ 1,5 DH ** | | |

It is recommended that motors running on alternating current be used rather than those running on continuous current. The table that follows provides some general guidelines for the distances to be placed between the probe and asynchronous motors, depending on their power

Position of the conveyor belt inside the probe

• The conveyor belt must pass as close as possible to the lower surface of the tunnel. In order to prevent it from accidentally rubbing against the probe it is advisable that it be supported within the probe by means of a sheet of insulating material , which is thick enough to support the weight of the material being transported (approximately 5-20 mm). It is necessary to take this measure when the belt is of considerable length and must therefore be supported, while at the same time prevented from vibrating. The sheet must not touch the probe (in the illustration an intervening distance of 5-10 mm is shown); if it were to touch the probe it could send vibrations to the antenna. In any event, if there is a supporting metal layer for the belt, when it arrives at the probe, it must be interrupted for a distance D, to both sides of the antenna.

| Models THS/M THS/A Other models |

| | | D ≥ 4 DH ≥ 3 DH ≥ 2 DH | | |

N.B.: THS/M Model: if the product is contained in an aluminium tray, the

optimum distance between the bottom of the tray and the surface of the tunnel is 20-30mm.

N.B.: In the standard structure, the conveyor belt passes through the probe in

both directions to avoid having to cut and rejoin it if the probe is replaced. If necessary, carry out the join as described in the “Maintenance” section.

Inserting the conveyor belt on the THS/A model

The THS/A model allows the installation of one side of the conveyor belt through the probe, without cutting the belt itself. The probe has a short section on its side which can be removed to insert the belt. Procedure • Remove screws S. • Remove section A. • Move the belt into the probe, or the probe over

the belt, depending on the requirements of the structure.

• Fix section A in place again using screws S.

• BS should be assigned the desired value of the transit speed (the current speed is detected by the system based on the working location of the inverter, or via an encoder if fitted).

• Assign to the KE parameter the number of pulses per revolution of the encoder.

• Assign to the DI parameter the value of the diameter of the motor roller (see table)

• Assign the maximum motor operating frequency to parameter MI.• Assign the maximum motor current consumption to parameter

CU. Some structural relationships must be observed:

BL ≤ BS ≤ BM BL ≥ 20 x KT BM ≤ 60 x KT

The parameter KT depends on the system configuration, and can be determined using the following procedure (it is necessary to obtain a transit speed measurement device):

1. set KT=1.000 2. set BS=50 3. activate the motor and measure the speed of transit Vn 4. calculate KT = Vn/50

By changing the value of BS, the speed can vary between 40% and (2 x MI)% of the nominal value of the motor (corresponding to operation at 50Hz). N.B.: by modifying the value of KT, the parameters BL and BM are automatically set to nominal values, respectively 20 x KT and MI x KT. BL and BM can also be modified manually. Example: Motor: operating frequency 50Hz ; maximum frequency 60Hz; maximum current 3A; Encoder 100 impulses/rev.; Roller diameter 60mm, belt thickness 2mm; Desired speed 45m/', minimum 25m/', maximum 50 m/'. • Set: MI=60, CU=3.000, DI=60+(2x2)=64 • Determine KT via the procedure described above:

KT=1.000, BS=50 measured Vn =55 m/' KT=55/50=1.100 • Set BL=25 (correct value to give 20KT=22) • Set BM=50 (correct value to give MI x KT=66) • Set desired speed BS=45

N.B.: The BS parameter is memorised individually for each type of product defined. If required, several speed parameters may be set for the same material by defining an equal number of product types.

Photocell self-diagnosis If the photocell is in a continuously active state for a long period, this is interpreted as a malfunction of the sensor by the self-diagnosis system. There are many possible causes (wrong position, short-circuited wiring etc.). The self-diagnosis message may appear:

- in the case of a conveyor belt without encoder or with Power Control Box, with the belt stopped or moving - in the case of a conveyor belt without encoder or with Conveyor Control System, with the belt moving.

The system is not designed to signal a pack which is stuck for some reason in front of the photocell. For this reason, when the system can detect whether or not the conveyor belt is moving (i.e. when it is equipped with an encoder or with the Conveyor Control System power supply unit), the self-diagnosis function gives an alarm only if the photocell is in a state of malfunction when the belt is moving.

On systems without encoder or with the Control Power Box, it is the installer’s and operator’s responsibility to ensure that material does not remain in front of the photocell when the belt is stopped: if it does, the photocell will be continuously active even though it is not malfunctioning. If the foregoing situation can not be avoided, it is advisable to disable photocell self-diagnosis (Parameter PA)

The ejection time ET must be determined by experimentation, as it depends on the type of ejector

To minimise the number of packs rejected at each alarm, it is recommended that Dp is longer than L, so that only one pack is ejected each time the ejector is activated.

Dse ≥ PL + 0,5xL + BS 60 x (ejector response time)

BS: transit speed, in m/min

For accurate analysis, the previous product must have left the tunnel before the next one passes through


Applications at high speed (belt speeds greater than 60 m/min) In this case, the response times of the photocell, metal detector and ejector can not be ignored. We would generally advise users to check operation of the ejector experimentally, changing its position and adjusting parameter ED.

Mechanical installation of a bar code reader

Safety precautions Although the power of the laser beam used in this barcode reader is very low, it can be dangerous to the human eye if stared into for long periods of time. Careful attention must be paid to the warnings on use of the laser. These warnings refer to regulations enforced by local authorities. IEC regulations Warning labels indicating laser radiation and the reader classification are applied to the body of the reader:

Fig.II-29 The device is classified as a Class 2 laser product according to the rules indicated in IEC publication N. 825-1 (1993).

Turn the power off when opening the reader during maintenance or installation to avoid dangerous laser radiation.

Barcode reader kit The barcode reader can also be installed on the THS system at a later date: a special kit is available for this purpose, and includes an enabling code. The reader is available in two versions:

• Picket-Fence, optimised for codes with vertical bars • Step-Ladder, optimised for codes with horizontal bars

1 reader 2 Bar code test chart (PCS 0.9) 3 Mounting kit: - bracket- screws

Fig.II-30a composition of the barcode reader kit

Fig.II-30b dimensions


Distance between the reader and the metal detector probe and distance between packs The reader is mounted upstream of the probe in order to read a code stamped on the pack. If the code is recognised, the reader sends a command to the metal detector to select the relevant product type. The time required by the THS to process the barcode is usually insignificant, but becomes important if the band is changed due to a modification in the type of product.. When the metal detector receives the signal to change product type, an internal adjustment procedure is activated the length of which determines the minimum distance between two packs with different codes, that is to say containing different products.

Position of the reader and the label in transit

A non-rigid mounting, using anti-vibration supports, should be adopted for the reader.

The two types of reader should be mounted as shown in the figures below. Attention must be paid to the position of the pack in transit, in order to ensure that the barcode can be read (angles P, S and T in the following figures).

Reading features The number of scans performed on the code by the reader, and therefore its decoding capability, is influenced by the following parameters:

• number of scans per second • code motion speed • label dimensions • scan direction in respect to code motion

At least 5 scans during the code passage should be allowed to ensure a successful read.

Step-Ladder mode

BCR bar code reader CMD code motion direction at LS speed LB laser beam Fig. II - 32

If scanning is perpendicular to the code motion direction ( “step ladder” mode), the number of effective scans performed by the reader is given by the following formula:

SN = ((LH/LS) * 350) - 2 These symbols signify:

SN = number of effective scans LH = label height (in mm) LS = label movement speed (in mm/s)

For example, the reader for a 25 mm high code moving at 500 mm/s performs:

SN = ((25/500) * 350) - 2 = 15 effective scans

Suitable values for LH and LS should therefore be chosen, so that:

LH/LS > 0.02

Picket-Fence mode

BCR bar code reader CMD code motion direction at LS speed LB laser beam Fig. II -33

If scanning is parallel to the code motion, (“picket fence” mode), the number of effective scans is given by:

SN = (((FW-LW)/LS) * 350) - 2 These symbols signify:

SN = number of effective scans FW = reading field width (in mm) LW = label width (in mm) LS = label movement speed


Reading field width depends on the distance between the label and the reader. The following figure gives the reading diagram for the following conditions::

• code = interleaved 2/5 or code 39 • PCS = 0.90 • P angle = 0° • S angle = 10° • T angle = 0°

Fig. II -34 width of the reading field

For example, for a code 50 mm wide moving through at 1500mm/s at a distance from the reader corresponding to a reading field of 200mm, we get:

SS = (((200-50) /1500) * 350) - 2 = 33 effective scans The position of the reader must therefore be chosen so that FW is at maximum, based on the reading diagram, and LW e LS should be chosen so that

(FW-LW)/LS > 0.02

• Distance between reader and metal detector probe • code transit speed • label dimensions

Automatic ejection with alarm synchronisation (EM=F) Operation with automatic set-aside of contaminated material. The set-aside method can vary: an ejector may be used – without halting the production line – or the material can be eliminated by using a retractable belt or by inverting the direction of the belt. This application is typically used for loose material. The mode allows the following settings to be selected:

–- alarm relay activation time (AT parameter); – ejection distance (ED parameter); – selection of activation time of the ejection relay (ET parameter).

Inputs

Make all connections relating to input lines using screened cable, connecting the shielding only at the THS system end to the contacts marked with the symbol which are provided on the various connectors.

Bar-code reader The bar-code reader is supplied upon request: for connection, follow the indications in the plan on the previous pages.

Downstream belt authorisation (Following conveyor - Conveyor Control System only) When active, this input indicates that the downstream belt is operating and can accept the product.

Photocell When active, this input indicates the passage of the product in front of the photocell. The input is monitored by the self-diagnosis system.

Ejection confirmation (Eject confirmation) When active, this input indicates the passage of the product into the set-aside container. The input is monitored by the self-diagnosis system.

Container full (Full bin) When active for at least 5 seconds, this input indicates that the set-aside container is full (the malfunction relay is activated).

Impulse encoder (Encoder) This input is used to measure the speed of the conveyor belt if an encoder has been installed. The sensor must provide impulses, the amplitude of which is indicated in the table “Electrical connections”, with a minimum frequency of 2 Hz and a maximum frequency of 1kHz. It may be contact type, open collector (NPN o PNP) or push-pull. For correct operation a coefficient KE must be determined during installation and set-up, as per the procedure described in the para. “ Transit speed “.

Alarm reset (Reset) When active, this input forces the Metal Detector to exit from the alarm state (used in the case of operation with belt block and manual reset).

Inhibition When active, this input disables the detector: it is generally used to avoid false alarms caused by the start-up of the conveyor belt when it is not possible to adjust the mechanical structure of the belt. Alarm inhibition when belt is switched on If the start-up of the belt is accompanied by interference which is serious enough to cause a false alarm, the alarm can be inhibited: • Control Power Box:

• connect a contact which is activated at start-up to the inhibition input; • set the IN parameter to a suitable value determined by experiment (see “Programming” section).

• Conveyor Control System: simply set the IN parameter to a suitable value determined by experiment (see

“Programming” section).

Air pressure sensor When active, this input indicates that the compressed air pressure is sufficient for the ejector.

Container absent (Bin absent) When active for at least 5 seconds, this input indicates that the set-aside container is not in its place (the malfunction relay is activated).


Operating instructions

List of preliminary checks If the equipment is being switched on for the first time, some checks must be carried out and the value of some operating parameters must be set. These operations, which are listed on the first page of the INSTALLATION section, are described in the subsequent paragraphs in this section.

Switching on the metal detector

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 Power supply unit There are dangerous voltages inside the power supply unit. Close the cover and keep the key safe so that it is onlyavailable for use by trained personnel (Regulation EN 60204) Conveyor belt motor The motor can reach high temperatures during use: do not touch the motor or bring inflammable materials close to itwhile it is operating or immediately afterwards. Ensure that the cooling air intakes are not obstructed, and that there is free air circulation WARNING: do not set the motor in motion without the conveyor belt: this may lead to damage due to excess revolutionsand consequent overheating.

Checking the safety features Before switching on, check that the safety devices with which the system is fitted are in good condition: 1. rollers: protection crankcase for the pin 2. rollers: lower protection panels 3. ejector: protection panels (if fitted) Also check operation of the emergency button with the belt in motion.

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.

Keep the power supply unit panel closed. The key must always be in the possession of an authorised person.

Fig. III-6

Signals at power-up The detector is designed to be switched on directly from the electrical panel that controls the production line. The power supply unit does however contain an auxiliary switch I2, which is normally in the ON position.

The presence of mains power supply is signalled by the lighting up of the indicator located on the control panel (Conveyor Control System) ... Fig. III-7a

... or of the green LED L2 located on card ALM, near switch I2 (Control Power Box). Fig. III-7b

When it is first powered up, the Metal Detector’s configuration includes 5 factory-set passwords (shown in the test card at the end of the manual). It is extremely important that the person in charge of the detector modifies the passwords in order to avoidunauthorised access to programming.

When the device is turned on, the display lights up, as do the indicators located on the front of the electronics unit. More specifically, the display shows, in sequence, the serial number and the version of the software program that drives the power supply unit; after that the following is displayed:

THS V3.xxx Product productname |

Fig.III-8

in which: THS identifies the model

V3.xxx identifies the software version of the metal detector

productname indicates the type of programming, specific to one product, which may be chosen from among 250 stored sets, of which 249 can be defined by the user (see Programming chapter); each stored programming set is customised and relates to a specific product to be monitored.

Signals given during 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, subdivided into 20 sections. When the signal increases, the bar extends towards the right. The alarm threshold corresponds to 10 illuminated sections: the sections from 1 to 10 are bars, those from 11 to 20 are asterisks

Checking for environmental electromagnetic interference The THS Metal Detector has very high immunity to electromagnetic interference. However, it may happen that electrical devices, usually power devices, cause interference which is strong enough to lead to false alarms. To identify these sources of interference the indication of the signal received from the probe, which the detectors normally shows on the display, can be used. Under normal conditions, the indication on the display should correspond to that in Fig. III-9a.

Display Messages The Metal Detector display shows messages relating to its current mode of operation:

Use of the conveyor belt

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 off on motor malfunction ! M off metal detector alarm ! off

• Press the start/stop button to switch on the motor: check that it starts up, and that the “motor

on” indicator comes on and the “motor off” indicator goes off.

• To stop the motor press the start/stop button again: check that it stops, and that the “motor

on” indicator goes off and the “motor off” indicator comes on.

• Fixed-speed Conveyor Control System: check the manual movement of the motor using the and keys (if parameter MM=ON).

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.

N.B.: during programming of the metal detector, the Conveyor Control System keypad is disabled. Vice-versa, while the Conveyor Control System keys are being used, metal detector programming is disabled.

Automatic stop If nothing passes through the metal detector for the length of time set by parameter ST (see Programming section), the conveyor belt stops automatically.

Alarm reset In the case of an alarm, the contaminated product is ejected from the product conveyor according to the type of operation which has been selected: • in operation with automatic ejection, the belt is not stopped and the contaminated product is sent into a set-aside

container which should be emptied periodically by the operator. In this case, the detector resets automatically. • in operation where the conveyor belt is blocked, the belt is stopped and the contaminated product is positioned in the

exit area of the metal detector for manual removal by the operator (N.B. all material between the probe and the stop line must be removed!).

In this case, the belt only restarts when the operator pushes the appropriate button. In the case of the Conveyor Control System, this button is incorporated into the control panel:

Action Indicators and results

press once to reset the metal detector alarm the metal detector alarm indicator goes off

press again to restart the motor the motor restarts

Automatic operation using a bar-code reader The THS system can, upon request, incorporate a bar-code reader for automatic selection of the specific parameters of the product in transit. This avoids having to halt the production line frequently. The reader is installed upstream of the probe so as to read a code stencilled on the pack. If the code is recognised, the reader sends a command to the metal detector to select the analysis programme.

If the code is not recognised due to lack of legibility or because it is not on the list of enabled codes (see parameter CD in the Programming section), the reader does not send any signal to the metal detector and the analysis program remains that selected for the last pack). In this case, also, the pack can be expelled automatically from the production line by enabling parameter NE When the metal detector receives the signal to change product type, an internal adjustment procedure is activated the length of which determines the minimum distance between two packs with different codes, that is to say containing different products. This distance is as follows:


THS/3F

with change of band (BA parameter) between one product and the other

D min = (probe length) + 3000 mm

THS/3F without change of band (BA parameter) between one product and the

other

D min = (probe length ) + 300 mm

Other THS models

D min = (probe length ) + 300 mm

Attention must be paid to the position of the pack, or rather of the label, while in transit: this should be parallel to the direction of transit so as to ensure that the barcode is legible.

Photocell self-diagnosis If the photocell is in a continuously active state for a long period, this is interpreted as a malfunction of the sensor by the self-diagnosis system. There are many possible causes (wrong position, short-circuited wiring etc.). For details see the “Self-diagnosis” paragraph in the Maintenance section.


Programming the metal detector according to the kind of product The operating mode of the metal detector according to the kind of product is determined by the following parameters:

• TX program (TP parameter) except for THS/MN • Sensitivity (SE parameter) • Analysis mode (AM parameter) • Band - only on the THS/3F multi-frequency model (BA parameter)

The factory settings are suitable for dry products (biscuits, pasta, dry frozen food,...). We would remind you that:

• in the case of products with "difficult" characteristics, it is advisable to call CEIA's Technical Department in order to request production of specially-designed equipment.

• it is always advisable to optimise installation in line with the criteria described above in order to obtain maximum sensitivity and maximum rejection of environmental interference.

Procedure for minimising the "product effect" The goal of this procedure is to obtain the following operating mode:

a the detector does not set off an alarm when the conveyor system is active and some of the pure product, without any metallic contamination (with aluminium tray onTHS/MN), passes through the probe.

b the detector sets off an alarm when some of the product containing a metallic sample passes through the probe

It is important to make sure that the product always passes through the probe at the same point and with the same orientation, in order to obtain the best results from this procedure: Procedure for automatic product acquisition (not applicable to the THS/M model) This procedure comprises the automatic acquisition of product characteristics in order to identify the contribution to the received signal due to the metal mass to be detected. The characteristics are acquired progressively by making the product pass through the metal detector several times. The procedure alters the settings of the following parameters:

• SE and TP, if TN>1 (only SE on THS/MN) • Only TP if TN=1 • BA, on model THS/3F if MB=ON

The procedure must be completed once started. Do not change any parameter setting during the procedure. 1 It is advisable to create a new product using the command New P. 2 Set the Analysis Mode parameter to a suitable value (see the “Analysis Mode Selection Criteria” section). In the

case of the THS/3F model, the correct value of the MB parameter must be selected (ON: autolearn with automatic selection of the operating band; OFF: autolearn with operating band pre-set using the BA command). In the case


of multi-band operation(MB=ON), select the desired value for the OS parameter. 3 Set “Autolearn=ON”. Exit from the programming phase and follow the display instructions. 4 Make the product pass several times through the metal detector, according to the value of the Transits

parameter (N.B.: in the case of loose product, the device automatically proceeds to analyse it correctly). N.B.: in the case of model THS/3F, if MB=ON, carry out 3 x TN transits, with TN=2,3.... The message “Pass product” appears on the display, and the buzzer is activated (if enabled).

5 At the end of the transits the detector exits from the autolearn phase and the standard message appears on the display.

6 Final operating check 6.1 Pass some pure product through the detector: the device should not set off any alarm.

6.1.1 Pass some of the product with a metallic sample: the detector should give an alarm. In such a case, the procedure has been successfully concluded.

6.1.2 Otherwise, increase sensitivity and check that the bar-graph indication is not higher than 8 points during the transit of uncontaminated product.

6.2 If the detector gives an alarm whenever some of the pure product passes through the probe, decrease the “Sensitivity” parameter until the detector does not give an alarm (this is probably due to non-uniformity of the product).

7 If a periodic test on the product is required, set the effective diameter of the metal mass used in the relevant parameter in the MD Test menu: parameter FD if the sample is of ferromagnetic metal, parameter SD if stainless steel, or parameter ND if diamagnetic. In this way, the test report will show this value next to the result of the test carried out.

N.B.: if the product can vary significantly in its electromagnetic characteristics, adjust parameter SA (Sensitivity Adjustment)

In each case it is advisable to check operation with all types of detection, and to choose the one which provides the highest level of sensitivity.


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.

Test using a sample defined by the customer The reference sample is identified at the end of the installation phase based on the customer’s specifications; the

sensitivity, trajectory and orientation of the sample must be noted if it is not spherical. This sample should be kept under constant conditions, and is used periodically for the test, which should be carried

out under the same conditions as the end-of-installation test.

Test using a CEIA sample The reference sample is one of the CEIA spherical samples available in various sizes and in three types of metal

(ferrous, non-ferrous and stainless steel) Determine by experiment the sensitivity needed to detect the sample, or carry out the procedure for minimising the

product effect Enter the diameter of the sample in the FD parameter (or SD, or ND, depending on the type of metal used) Set the intervals and the waiting period for carrying out the test, and whether or not the malfunction relay is activated

if the test is not performed (see QA Configuration menu)

Periodic test management At the end of the period Test interv. (from when the metal detector is switched on), a message requesting a test is displayed:. ( this can also be signalled via an optional lamp). The check can be carried out either by the Quality-control Operator or the Head of Quality Control. N.B.: to exclude the reminder to carry out the test periodically, set parameter Test int.= 0.

Mode B

Used for loose product and belt stop. No photocell required. This includes halting of the production line, manual elimination of the contaminated material and manual reset by the operator.(See also parameters ED and ET). Note: The metal detector does not check if there are any subsequent fragments in the material immediately following: all material under the probe must therefore be eliminated along with the part that caused the alarm. To minimise waste of material it is advisable to select a low setting for the ejection relay activation delay.

Mode F Used for loose product and ejection effected using retracting band or flap. No photocell required Includes automatic set-aside of contaminated material. (See also parameters ED and ET)

Mode S Used for packed product and ejection effected using pusher. Photocell required. Includes automatic set-aside of contaminated material with photocell synchronisation. (See also parameters ED, ET, PD, PH)

Note: each password accesses programming at the appropriate level (operator, supervisor, …)

Long-distance connection to a single metal detector (via RS 485) Identical to the above.

Network connection (via RS 485) Using RS 485 transmission, several metal detectors can be connected in a network. In this case, the PC acts as master and the metal detectors as slaves. So as to allow each individual metal detector to be identified, the following steps must be taken: Set a password on each metal detector (N.B.: the password can be the same if so desired). Set a different Line ID identification code for each metal detector (line ID parameter ID=1001, 1002, 1003, .).

Maintenance

Any maintenance or repair of the device while open and energised should be avoided, and in any case should only be carried out by trained personnel who are fully aware of the risks which the operation entails, following the instructions given in the “Maintenance” section.

When the mains is disconnected using the main switch S1 of the Conveyor Control System, the power supply section is deactivated, but the contacts which are connected permanently to the mains, e.g. the relay outputs, remain energised. N.B. When the I2 service switch is turned off, most components remain energised.

fig. V -1a fig. V -1b

Removal of the safety protections fitted to the device is strictly prohibited.

Self-diagnosis The internal diagnostic system monitors the operational status of the metal detector. If a fault is detected, the following are activated in addition to a message on the display:

• the illuminating alarm indicators • the buzzer (if activated) • the fault relay (if Fault relays parameter is ON) • flashing light (if Fault relays parameter is ON)

Fault status can only be reset by eliminating the cause of the fault.

Table V-2 Message Probable cause Action Test time out Time-out for pre-programmed

test. Carry out the test

Fault: power Power-supply section faulty

Contact service technician

Fault: probe Antenna connection broken

Contact service technician

Fault: ejection ** Ejection of material not carried out

• Check that the ejection times are correct. • Check that the ejector is not blocked • Check photocell operation (positioning, connections

etc.) • Check the Confirm Ejection input connections When the cause of the fault has been eliminated, press the E key to reset the alarm status.

Bin full Storage container full Empty it Press E key to reset the alarm status

Fault: communication Fault in communication between SCD and ALM cards

Check that the power-supply voltage is stable and corresponds to the values on the identification plate. Check the wiring If the wiring is correct, replace the cards

Fault: motor alarm ("motor alarm" indicator activated)

Overloading of the belt motor Wrong setting of CU parameter

Remove the cause of overloading and press E key. Set a proper value of CU parameter and press E key.

Fault: air pressure Compressed air pressure too low

Check the compressed air connection. When the cause of the fault has been eliminated, press the E key

Photocell fault *** Photocell malfunction or pack stuck in front of photocell

• check there is no pack stuck in front of the photocell • check the photocell connections • Check the positions of the photocell and the

retroreflector • replace the photocell When the cause of the fault has been eliminated, press the E key to reset the alarm status ****

Memory card not installed (THS system not operative)

Memory faulty or absent Check presence and connections of the SPM external memory card (see para. "Replacement of SCD card"

Compatibility error SCD card incompatible with the data stored in the SPM memory card

Use compatible SCD card (ask service personnel)

*Enabled by the Fault relays parameter **Enabled by the Ejection confirmation parameter *** Enable via the PHOTO Alarm parameter **** The self-diagnosis message may appear: - in the case of a conveyor belt without encoder or with Power Control Box, with the belt stopped or moving - in the case of a conveyor belt without encoder or with Conveyor Control System, with the belt moving The system is not designed to signal a pack which is stuck for some reason in front of the photocell. For this

reason, when the system can detect whether or not the conveyor belt is moving (i.e. when it is equipped with an encoder or with the Conveyor Control System power supply unit), the self-diagnosis function gives an alarm only if the photocell is in a state of malfunction when the belt is moving.



Storage Store the system in its original packaging, or in a way that protects it adequately from atmospheric agents or other possible causes of damage (moving objects, weights, solvents etc.). Storage temperature (Regulation EN 60204): -25°C - +55°C long-term, +70°C for 24 hours maximum.

Transport and movement of the conveyor belt

Disconnect the system from the various power sources before carrying out any movement. Use lift trucks or sling the load-bearing structure, and ensure that the load is balanced during movement. Avoid deforming the structure or its component parts.

Never attach lifting gear to the Metal Detector probe or the actuators. Keep the packaging materials for possible future transport.

Fig. V-2

Adjustment of conveyor belt tension This is carried out on the roller on the side opposite the motor roller. To adjust the belt tension, loosen screws A on both sides by the same number of turns, so that the slack in the belt at the entrance to the probe appears as in the figure (about 0.02 x length of the belt, s=0.02 D).

Symptom Probable cause Action Power supply unit-metal detector system off

Malfunction of the power supply section No line voltage Unstable or partial connections

Switch off, wait a few minutes to let any self-resetting components inside cool down, then switch on the system again. If the problem persists, replace card ALM Check the power supply connections Check insertion of the ALM card connectors

Power supply unit-metal detector system alternates between on and off

Malfunction of the power supply section

As above

Metal detector does not give an alarm in the presence of metal masses of the same type as the reference sample and of equal or greater mass

Metal detector inhibition Wrong detection parameters for the current product Product effect SCD card malfunction

Carry out the following operations in sequence: Set IN=0 Disconnect the ALM card connectors which do not link up to the power supply or probe. Select the “Default” product and check, with the sample provided with the device, that the detector gives an alarm. Carry out the autolearn procedure. Check the settings of the detection parameters (SE, TP, etc.) Carry out the autolearn procedure. If the procedure is not successful, replace the SCD card.

Metal detector gives false alarms with no product in transit

Environmental interference SCD card malfunction Line voltage insufficient or unstable

Carry out the “ Checking for environmental electromagnetic interference” procedure. Deactivate all electrical and mechanical devices surrounding the detector, or move it into a place which is guaranteed free of interference. Disconnect the ALM card connectors which do not link up to the power supply or probe. If the interference signal remains the same, replace the SCD card. Check.

Replacing Card SCD If the control card has to be replaced, the serial number of the device must be quoted in the order; the card will only be able to be used with that same detector.

Procedure • Switch off the device • The card is attached to the detector control panel. Remove the control panel by unscrewing the fixing screws, taking

care not to pull on the internal connecting wires. • Disconnect the card and connect the internal wires to the replacement card. • Plug the SPM memory card from the old control card into the new one. N.B.: the memory card contains all the

device’s stored programming, product and event data. • Reassemble the control panel. • Switch on the detector and reset the programming. • Carry out the TL Autolearn procedure:

• The procedure must be carried out in an interference-free environment: deactivate the THS conveyor belt and any other power devices in the area.

• Set the parameter TL Autolearn = ON and exit from programming. • The message “Pass” will appear on the display: press forcibly for at least a second on the probe (see figs. below –

press in the middle of the belt width at either the entrance or the exit, but NOT in the centre). In the case of models THS/PH and THS/G, make the probe vibrate. Repeat TL autolearn for each band (BA) and for each channel (CH).

• N.B.: in the case that the procedure is not carried out, or is carried out improperly, compensation for the products

may not be correct. As a check, select the “default” product and make some tests with the sample indicated in the test card enclosed with this manual.

• Check that the system operates properly with all the products stored in memory. The SCD card stores the values of all the operating parameters, including those of the power-supply and control

unit. If the power supply unit is replaced, therefore, it is not necessary to reprogram the system..


Checking environmental electromagnetic interference The existence of interference is indicated by false alarms or by the display of several segments on the bar-graph when the conveyor belt is stopped and there is no product in transit:

Fig.V-9a. Example: signal well below the threshold level

Fig.V-9b. Example: signal just below the threshold level

Fig.V-9c Example: signal above the threshold level (alarm).

For correct operation, the bar-graph indicator should not have more than THREE bars lit. To eliminate the interference, the first thing to do is to identify whether it is electrical or magnetic: 1 Set parameter TX=OFF. . (NB: on model THS/MN, set the switch on the internal card of the probe power-supply unit to OFF) 2 If the interference remains the

same, it is electrical Examples of sources of electrical interference: electric motors, inverters, power cables, lighting

3 If the interference decreases, it is of a mechanical nature

Examples of sources of mechanical interference: unstable anchoring of the metal detector (vibrations), metal masses moving in the vicinity of the probe, intermittent loops, metal fragments in the conveyor belt.

To increase immunity to mechanical interference, adjust the AM parameter (see paragraph “Analysis mode selection criteria” ). To eliminate sources of interference, refer to the illustrated notes in the Installation section.
