- Page 13 Metal Detector Principle Of Operation The DSP 2 model metal detector operates on the balance coil full loop detection system. Three equally spaced coils surround the aperture or opening through which the product to be inspected passes. The center coil is connected to an oscillator circuit to produce an electromagnetic field.
-
Page 14: Mechanical Installation
Mechanical Installation The power supply unit and control unit (if remote) may be mounted as any other electrical control would be, wherever convenient. However, the search head must be installed as per the following instructions if correct performance is to be expected. -
Page 15: Metal Free Area
Metal Free Area While the detector is shielded above, below and on the sides, metal objects have to be kept from the entrance and exit of the detector opening as shown below. No metal can be located in this area. Large moving metal should be kept fifty (50) percent further away or at least two (2) times the smaller aperture dimension. - Page 16 Loop Effect Besides observing rules for metal-free areas, precautions should be taken to prevent the occurrence of loop effect. Loop effect is caused by an electrical loop in the conveyor, which is allowed to make intermittent contact (see Figure 10). This loop, when closed, can produce a large electromagnetic field.
- Page 17 Roller Isolation Loop effect is most prominent with detectors having an aperture height ( smaller dimension ‘B’ ) greater than five inches and a width ( or ‘A’ dimension ) greater than twelve inches. Loops as far as three feet away may affect the operation of the metal detector.
- Page 18 Vibration Efforts should be made to reduce excessive vibration, especially if a conductive (wet) product is to be inspected. Conveyor Separation If you have a separate conveyor for the metal detector system ( which is preferred ), you must make certain that this conveyor does not make intermittent contact with the infeed and discharge conveyors.

Page 19: Electrical Installation
Electrical Installation When choosing the power supply line for the metal detector, it should be remembered that starting of heavy electrical machinery creates very considerable (though momentary) voltage drops in the line. Such "spikes" can cause the metal detector to trigger. Since the power consumption of the detector is very low (approximately twenty-five watts), it is recommended that a lighting circuit be used for its supply rather than a machinery power circuit. -

Page 28: Initial Setup
Initial Setup This manual describes only the features which can be used in Conveyor Applications. The following must be set in order for the detector to function properly (in order): • The application type (conveyor) • The application parameters (belt speed, aperture size, photo eye distance) •... -
Page 29: Edit Application
Application Path: Setup/Application There are six application types available: è Conveyor Gravity Tablet Pipe Custom This manual refers only to Conveyor type applications. Conveyor applications require three numbers which the detector will use to optimize it’s operation: • Aperture size •... - Page 30 Belt Speed This needs to be an approximate value only. There are two ways to enter the belt speed - manual and automatic learn. The automatic learn requires a photo eye to be present. Manual: Measure or calculate the belt speed and enter this value. Hint: Measure the distance an object travels during 6 seconds.
- Page 31 Rejects Path: Rejects Clear Reject Counter This button clears the reject counter displayed on the top menu. Press to reset to ‘0’. Test Reject This button when pressed will activate the reject output. This is used to test the action of the reject device. This will not inhibit normal occurring rejects and the test function will return to normal when leaving this menu (Exit).
-
Page 32: Photo-Registration
Photo-Registration If the system is equipped with a photo eye it can be used to increase the accuracy of the reject device. This is recommended where discrete packages are inspected. Especially those exceeding 6” in the direction of travel. Photo registered timing can allow the reject device to accurately reject the product regardless of where the contaminant metal is located within the product. - Page 33 Reject Confirm Reject confirm will require external hardware which may not be installed on your system. Contact Goring Kerr for assistance. This option permits the reject device response to be automatically monitored by the detector. Select from the following options: No reject confirm One sensor Two sensor (this option monitors both strokes of the reject device)
- Page 34 Product Compensation Metal detectors are capable of detecting metal by measuring two characteristics: Conductivity: ( Wet ) Any conductive material will generate a specific error signal. However, many food products by nature are electrically conductive themselves. Salt and moisture content combine to produce conductive product effect which must be overcome in order to detect small metal contaminants.
-
Page 35: Definition Of Terms
Definition of Terms Phase Refers to the phase vector of the product signal. Mode Groups the phase vectors into wet (near 0°) and dry (near 90°) Residual Product effect that cannot be eliminated with phase compensation. This feature requires the installation of a photo eye and can only be used with discrete products. This feature is not used in gravity applications. - Page 36 Learning the Product Press the Learn hard key, then press the Start Learn button and run the product through the detector. Note: the product must turn on the green Product Light in order for the Phase Point to be learned. A red Product Light indicates excessive product signal and the gain should be reduced.
- Page 37 Sensitivity Path: Sensitivity This menu sets the sensitivity number which the detector is using. Increasing the number results in higher sensitivity detecting smaller particles of metal. Manually adjust the sensitivity using the + and - keys, then press Accept to enter the new value. Range: 0-1000.
- Page 38 Product Library Path: Product (Hard Key)/Product Library Individual product records which can store information such as sensitivity settings, reject parameters, etc. can be created. Since most parameters will be shared by all the products it is preferable to set one product record completely including all the reject parameters and then copy this product to a new product number.
-
Page 39: Default Passwords
Password Path: Setup/Password The system has three levels of user passwords. Level 3 is the highest access level. Most common functions can be assigned a specific password level. This allows the user to design their own password structure. Typically, low level functions such as Select Product, etc. would be assigned a level 0 (no protection) or level 1 password protection. -
Page 40: Special Functions
Special Functions Path: Setup/Special The menus under special should only be set and adjusted after reading the pertinent section of this manual. Language Select from English, French and Spanish. When French or Spanish is selected, only commonly used menus will be displayed in that language, all others will remain in English. - Page 41 Configure Fault/Excess Reject Configure fault is used to set the parameters for the fault source called excess reject. Excess reject monitors the number of rejections occurring within a window. The window is either a timed function or when the unit has a photo eye, a function of the number of products.
- Page 42 Status Path: Status This menu displays a summary of the important parameters which have been set. SYSTEM This shows the type of applications (gravity, etc.), the filter type, the current sample rate (SR), and if a photo eye is present. PHASE This displays the current phase point, the phase state (auto, fixed), the mode, and the state of residual compensation.

Page 43: Service Data
Service Data This menu displays service and troubleshooting information. FREQUENCY This displays the frequency of the control panel. Example: 300Khz. LEVELS This represents a volt meter display of the search head signals. Three signals can be monitored here: the balance, the oscillator reference signal A and oscillator reference signal B. - Page 44 QA TEST The Test hard key can be used to access a QA test menu. This can be configured to record QA test occurrences separately from normal rejects, etc. The system can also be configured to request that the unit be tested. In this mode an interval is set, for example 4 hours.

Page 45: Fault Finding
Fault Finding Fault Light Will Turn ‘On’ If the detector senses a system fault the fault LED will turn on, the fault relay will change state and a fault message will be displayed at DETECT FAULT the top menu. Press the fault button display to access a description of the fault. - Page 46 Shaft Encoder Fault (EMU Fault) This fault refers to applications using variable speed timing and an external clock source. If a detection occurs, but the external clock pulse is missing, the detector will assume an EMU fault has occurred. Check the external clock source (shaft encoder), check LED LD 6 (in the power supply).
-
Page 47: Recommended Testing Procedures
Recommended Testing Procedures A complete and thorough test of the metal detector system must be done upon initial installation and whenever a major component of the system has been changed or altered (i.e. reject device repair, etc.). A complete check of the metal detector must include the reject device. - Page 48 Testing Schedule How often the detector should be tested must be decided by the user. If the test procedure can be designed to be simple it will help ensure that the test will performed more frequently. As a guide it must be decided how much product would have to be put on hold for re-inspection if a detector fails the test.
