Page 17: About Metal Detection
About Metal Detection Industrial metal detectors are used in the pharmaceutical, food, beverage, textile, garment, plastics, chemicals, lumber, and packaging industries. Contamination of food by metal shards introduced during the manufacturing process is a major safety issue in the food industry. Metal detectors are widely used and integrated into production lines and play a vital role in preventing contaminated products from reaching customers.
Page 18: How A Metal Detector Works
‘false triggering’. The robust construction and excellence in electronics and software design of Loma metal detectors provides a stable and reliable product where the likelihood of false triggering is minimised.
Page 19: Phasing
Safety First Phasing The diagram below shows how the magnetic and conductive properties of a product affect the product phase angle. Utilising the ‘Learn’ feature provided in the IQ + ST Metal Detector, an average for the net signal received from a product during inspection is digitally processed to provide a phase angle and amplitude.
Page 20: Tracker Feature
This could result in false triggering and rejection of good products. Loma Systems generally employ the use of fixed plastic guards fitted around both ends of the aperture. This serves a dual purpose in effectively preventing access to those areas and the accidental introduction of any metal contaminants.
Page 21 Each value shown is the diameter in millimetres (mm) of a spherical metal contaminant, as contained in Loma test wands. The detection performance figures quoted in the tables below are for indication purposes only and are based on previous experience with similar products and applications.
Page 22: Types Of Metal
About Metal Detection Detector performance is also affected by the position of the contaminant in the aperture. The least sensitive point is located in the geometric centre of the aperture, so this ideally is where to test the detector performance each time if practical, to ensure consistency. As metal gets closer to the sides (coils) of the aperture, the signal generated becomes larger, making it easier to detect.
Page 23: Testing Metal Detector Performance
Once again, if your company is a private label manufacturer, ensure that you agree upon any variation you make to testing procedures, in writing, with your retailer customers. To facilitate effective testing, all of Loma's Metal Detectors have an integral Performance Validation System (PVS) feature.
Page 24: Product Test Samples
‘Stale’ test packs may produce different product signals. Test Wands Loma Systems metal detectors are supplied with a set of plastic test ‘wands’ which contain spherical pieces of various metals in different sizes. These are convenient and easy to place into your test samples and also make the testing process even more efficient.
Page 25: Learn Feature
Safety First The test log file in .csv format may also be downloaded onto a memory stick via the USB port and then opened for analysis in Microsoft Excel. Manual Testing When testing is carried out manually, the results must be manually recorded and should include the following: ...
Page 26: Update Learn
About Metal Detection Update Learn The Update Learn process again consists of following on-screen instructions to pass a number of product samples through the detector aperture. This process can only be used for products that have already gone through a Full Learn process. A warning dialog will pop-up to inform you that a Full Learn is required if this has not been completed previously.
Page 27: Safety First
This section provides further details.  Noise Levels Loma metal detectors do not emit a level of noise that is hazardous. However, in line with current legislation, the customer should verify that the overall noise levels within the operating environment are within defined limits.
Page 28: Safety Awareness
A signed and dated EC Declaration of Conformity is provided with each metal detector delivered. Any modifications made to any part of the metal detector without the prior written agreement of Loma Systems will invalidate the EC Declaration of Conformity and also product warranty.

Page 44: Mounting A Detector Head Onto A Conveyor
Mounting a Detector Head onto a Conveyor Introduction Loma Systems have been manufacturing metal detector systems for many years and our current conveyor design incorporates this wealth of experience. There are a number of integration rules that have to be followed when fitting a new detector head to an existing or third party conveyor to attain optimal performance and avoid nuisance triggering.
Page 45 DRY mode. Loma metal detectors are designed to minimise any vibration or shock effects when operating with conductive products. To further enhance this resistance the conveyor must be designed with consideration to the above rules.
Page 46 Mounting Horizontal Heads for Use with Conductive Products Loma heads up to 350mm in height are supplied with an adjustable height mounting kit. The purpose of the height adjustment is to enable the centre line of the conductive product to pass through the “centre line”...
Page 47 Installation Moving metal excludes concentric rotating rollers. If they are concentric and can be guaranteed to stay that way, then they may be classed as fixed metal. However it is important to reiterate that they must be insulated from the conveyor at one end or it is possible that they will cause false triggering by creating an intermittent eddy current path.
Page 48: Connecting The Detector Head Electrical Supplies
Post Installation Problems  Spurious Triggering The Loma range of detectors is the product of many years experience and development. They are inherently reliable, provided that it is installed and set up correctly. Remember that the detector can detect can detect moving metal anywhere within its metal free zone. This is up to a distance of 3 times the smaller of the aperture dimensions away from the detector.
Page 49 Installation To connect an electrical supply, proceed as follows: Remove the six front cover retaining bolts and drop down the cover until it is held against the supports Remove the screw from the top of the metal cover plate and lower it down carefully The Mains Filter is mounted inside the panel housing mounted on the right hand side.
Page 50 Input / Output Signal Information To connect to external devices a Relay kit, Loma part number 6120PL500, consisting of a relay module, a cable that connects the relay module to the mini control board and some cable ties, can be supplied.
Page 51: Installing A Metal Detector System
On systems employing variable speed conveyors, special hardware is required to drive the CTB (conveyor time base) input on the micro control card. Conveyor systems supplied by Loma will already have this hardware fitted and commissioned, but when purchasing a detector head only, the following information should be observed when using a variable speed conveyor.
Page 52: Warnings
Following completion of the installation, commissioning of the machine should be carried out by a Loma engineer. An important part of this process is to run an Auto Configuration process through the...
Page 53: Receiving And Unpacking
Receiving and Unpacking Receiving the machine  On receipt of your Loma inspection machine, we recommend that you check the external packing for any signs of damage.  If the external packaging is damaged do not refuse the shipment but make a notation on the carriers delivery receipt and take pictures of the packaging damage.
Page 54: Adjusting / Levelling The Conveyor
Do not start the machine and initiate the use of any compressed air before the Loma commissioning engineer has approved the installation. Except where a metal detector head only is being supplied, all Loma metal detector systems require a clean and dry compressed air supply, primarily to operate the optional automatic reject system.
Page 55 Installation  Reject Valve – The Reject Valve is attached to the pneumatic assembly and contains five ports as follows: o Air Supply Input Port – The air supply from the Dump valve is connected to the input. o Air Supply Output Port 1 – The air supply is fed to one side of a reject device. For example when fitted to one side of a double acting air cylinder, the air drives a rod attached to a nylon blade to push product off a conveyor into a reject bin.
Page 56: Connecting The Electrical Supplies
Installation Therefore the only actions required are to connect the air supply to the input side of the air regulator using 10mm O/D tubing and set the air pressure using the regulator. The air pressure should be set to 80psi (5.5 bar) except when being used to supply an air-blast reject device when the pressure should be set to 100psi (6.9 bar).
Page 57 Installation To connect an electrical supply, proceed as follows: Unlock and open the Electrical Services Box to access the electrical services. The back of the Isolator Switch is located in the bottom right hand side of the cabinet when viewed from the rear. Beneath it on the bottom of the cabinet is the cable gland access for the power cable.
Page 58: Checking Belt Tracking (Pv Belt System Only)
Installation Do not start the machine and initiate the use of any electrical circuitry before the Loma commissioning engineer has approved the installation. Checking Guards  Check that all guards are securely fastened in place.  On some conveyors that are made to special order, hatches may be fitted to permit access to some areas of the machine.

Page 65: Reject Devices
About the Metal Detector Range Reject Devices Loma Systems offer a range of reject devices for removing contaminated products from your production line, based on a number of factors including the product type, its general dimensions, the general set up of your production line and of course how you wish to handle contaminated products.
Page 66: Air Blast
About the Metal Detector Range Air Blast The Air Blast reject device is suitable for removing contaminated wrapped products from your production line using a high pressure blast of compressed air to push the contaminated product off of the conveyor belt and into a reject bin. Generally a single nozzle is specified but a second nozzle can be fitted when required to provide more control or to reject over or underweight packs into a separate reject bin where the metal detector is being used in combination with a checkweigher.
Page 67: Reject Bins
An air pressure failure switch is fitted if the conveyor is supplied with either a pusher reject or a retracting band reject. The switch is set by Loma to operate if the pressure of the compressed air supply to the reject falls below 40psi (2.8 bar). The conveyor then stops.
