GENERAL The instructions given in this manual have been written clearly and briefly to enable an easy understanding of the actions necessary to operate this equipment. In order to ensure trouble-free and reliable service it is strongly recommended that operators of the equipment are provided with this manual in order to familiarise themselves with the controls and procedures.

  • Page 8: Introduction

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 3. INTRODUCTION This is the operating manual for the MET 30+ 1f and 3f range of metal detectors including horizontal, pharmaceutical, waferthin, vertical-fall and pipeline, with VFD or Touch Screen displays. The MET 30+ detector uses the latest developments in digital signal processing ensuring complete product integrity.

  • Page 9: Detection Envelope

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 3.2 Detection Envelope The MET 30+ detector software creates a detection envelope after an automatic setup is performed, it uses this envelope as a means of detecting metallic contaminants. For a signal from a metallic contaminant to operate the detection relay it must produce a vector signal large enough to pass through the periphery of the detection envelope.

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 3.3 Orientation Effects If a wire sample of a particular metal is passed through the aperture, it will be readily detected if the diameter of the wire is equal to or greater than the ‘spherical sensitivity’...

  • Page 11: Sensitivity Gradient

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 3.4 Sensitivity Gradient Sensitivity is higher around the peripheries of the aperture and somewhat lower through the central axis of the aperture. Quoted sensitivities are always given for the least sensitive area of the aperture, that being along the central axis of the aperture. 3.5 Product Effect Some products can produce electrical signals when passed through the metal detector aperture thus making it appear as though there is contamination present.

Touch Screens For the MET 30+ range of metal detectors equipped with a ‘Touch Screen’ display there are a number variations in operation, and additional features which take advantage of a larger display.

  • Page 13: Setting Up The Machine

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 4. SETTING UP THE MACHINE The detector and reject system (if fitted) should now be completely installed. The aim of this section is to describe how to set up the detector for a particular product, including automatic setting of detection parameters and calibration of timers for accurate rejection.

  • Page 14: Initial Test

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 4.2 Initial Test Every detector is shipped with test samples - small pieces of conveniently packaged metal with which to test the detector. Before the detector is shipped, it is set up to see these samples without false triggering (false triggering is when the detector indicates that it has seen metal when none is present, and is due to electrical noise, vibration, large product effect, etc.).

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 4.4 Timer Setup Note: The reject timer configuration for a pharmaceutical, waferthin, vertical fall and pipeline system are correctly configured in the factory and should not be amended. Every product has a timer associated with it. This timer is responsible for deciding when the reject mechanism should be activated after metal contamination has been detected by the software.
  • Page 17 Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 4.4.1 No Synchronising Photocell (Applicable for Pharmaceutical, waferthin, vertical fall and pipeline systems) Only two parameters are used in this situation: delay time and reject time. Figure 2 : No Synchronising Photocell When the detector detects metal it generates a trigger pulse.
  • Page 18 Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual When the detector generates a trigger a delay timer is started as for the "no synchronising photocell" situation. When the delay timer expires an enabling alarm timer is started. The reject mechanism will only activate while this alarm timer is active.

  • Page 19: Using The Software

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 5. USING THE SOFTWARE This section of the manual describes what the software does and how to use it. It is intended mainly for reference and is not meant to describe how the software would typically be used, or why certain options are required.

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual The exact form of the display varies with system configuration. If a variable speed conveyor is being used all timer values apart from reject time will be displayed as a number of tacho pulses (pul).

  • Page 22: Operator Menu

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual Entering the supervisor code allows access to supervisor functions in addition to operator functions and so on. If any of the four security codes have the same value, then the software will allow access in line with the highest level security code. For example, if the supervisor and engineer codes were the same then entering this code would allow access to the engineering options (as well as the supervisor options).

  • Page 31 Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual Note: that different cables and sockets will be required for RS422/485 as opposed to RS232. The second option allows adjustment of communications parameters for port B and works in exactly the same way as for port A. The exception is that port A is dedicated to RS232 and port B is a dedicated RS422/485 (multi-drop), which also ignores handshaking.

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual 7. SAMPLE TEST As high-resolution detectors are sensitive devices that may drift with changes in environment, it is prudent to have an organised procedure for physically checking the system. A known test sample, shipped with each detector, should be inserted into an identified fresh sample of the product and passed through the detector.

    Doc. Ref.No: Q875-0143/ENG Issue 2 12/01/10 Met 30+ Operating Manual When the operator has entered his P.I.N. number, the operator has 10 seconds in which to pass a test sample (reference #5). The display shows "Pass test sample" and a figure, which will count down from 9 to 1. If the detector fails to detect a metal sample and the count times out (reference #7), the red light is turned on and the reject is activated with the display showing "Test failed! <SELECT>".
