Installation \u2013 Mechanical<\/strong><\/h2>\n\n\n\n
    \n
  1. Select a suitable shaft to install the \u2018Rotech\u2019 unit to.<\/li>\n\n\n\n
  2. Use a 5mm drill to drill a pilot hole to a depth of 25mm into the centre of the end of the shaft.<\/li>\n\n\n\n
  3. Use a 10mm drill to open the hole to the required tapping size.<\/li>\n<\/ol>\n\n\n\n

    IMPORTANT! Take care that the shaft is drilled centrally.<\/mark><\/strong><\/p>\n\n\n\n

      \n
    1. Tap the 10mm X 25mm deep hole 12mm UNC.<\/li>\n\n\n\n
    2. Remove the rear cover the Motion Sensor\/Encoder and using a 10mm UNC socket wrench install the unit onto the shaft. Re-fit the rear cover.<\/li>\n\n\n\n
    3. Bolt the flexible securing strap to any convenient part of the machine frame work<\/li>\n<\/ol>\n\n\n\n
      \"\"<\/figure>\n\n\n\n

      As an alternative method of securing the Rotech end of shaft unit without the need for drilling the
      shaft, our unique Magcon unit can be used as shown below \u2013 see product data sheets for full
      details.<\/p>\n\n\n\n

      Installation \u2013 Electrical<\/h2>\n\n\n\n
        \n
      1. Always complete the mechanical installation before commencing the electrical installation.<\/li>\n\n\n\n
      2. Install a suitable junction box within 300 \u2013 600mm of the Motion Sensor\/Encoder.<\/li>\n\n\n\n
      3. Gland \u2013 Off the flexible conduit of the Motion Sensor\/Encoder in the junction box and connect
        the 2 or 3 wires to suitable terminals. (The flexible conduit and cable are supplied over-length
        they can be cut back and shortened as required)<\/li>\n\n\n\n
      4. Connect suitable wires and cable to route the Shaft Encoder signal back to the control panel.<\/li>\n<\/ol>\n\n\n\n

        Important<\/strong>
        The maximum distance recommended between the Motion Sensor\/Encoder and the control
        panel is 1000 yards.
        Armoured or screened cable should be used id the cable is routed in the vicinity of power
        cables.
        Do not route the Motion Sensor\/Encoder signal through multi-core cables carrying other
        signals or voltages.<\/mark><\/p>\n\n\n\n

        Alternative Installation<\/mark><\/a><\/p>\n\n\n\n

        An alternative method of installation is to house the Control Module\/Speed Relay etc. in a slightly larger terminal box.<\/mark><\/a><\/p>\n\n\n\n

        A mains signal (typically 110Vac) can then be switched on by the control module and then routed via multi-cores; unprotected cables etc. back to the control panel.<\/mark><\/a><\/p>\n\n\n\n

        Other Applications<\/h2>\n\n\n\n

        Motion Sensors\/Encoders are used extensively in many different industries for a wide variety of
        applications.<\/p>\n\n\n\n

        Besides measuring the speed of a rotating shaft, they can determine direction of rotation, angular
        position, and the number of revolutions or parts of revolutions completed.<\/p>\n\n\n\n

        Using screws, slides, racks & pinions these angular functions can be translated into linear or length
        functions.<\/p>\n\n\n\n

        The following are the more popular applications that \u2018Rotech\u2019 Heavy Duty Motion Sensors\/Encoders are utilised for.<\/p>\n\n\n\n

        Speed Indication<\/h3>\n\n\n\n

        Used in conjunction with a Digital Panel Meter to display RPM or linear speed of a Conveyor Belt.<\/p>\n\n\n\n

        Length Measurement<\/h3>\n\n\n\n

        Used in conjunction with a Counter unit and either a roller or wheel of known circumference, to
        measure cut-off lengths, total throughput, or to position material for a process operation.<\/p>\n\n\n\n

        Direction Indication<\/h3>\n\n\n\n

        Using a \u2018Rotech\u2019 Heavy Duty Motion Sensor\/Encoder with dual quadrature outputs, direction of
        rotation can be determined.
        This is most frequently used to detect if a heavily loaded conveyor starts to run backwards.<\/p>\n\n\n\n
