  • Page 8: Introduction

    Introduction The 686-Series Smart Vibration Switch is a low-cost electronic vibration switch designed to monitor vibration levels on rotating machinery (ie. fans and cooling towers) and trip an alarm or shut down machinery when a specified vibration limit is exceeded. An onboard accelerometer with precision, microprocessor-controlled electronics ensures reliable operation and accuracy.

  • Page 9: Operating Principles

    Operating Principles The Smart Switch operates over just two wires. It installs in series with any load (ie. annunciator, PLC or relay coil). To energize itself, the vibration switch scavenges power from the load’s power source. When the alarm threshold is exceeded, the switch is activated and the load’s power circuit is completed to facilitate the desired alarm or shutdown.

  • Page 10: Installation

    Installation When choosing a mounting method, consider closely the advantages and disadvantages of each technique. Typical mounting types are stud, direct adhesive, adhesive mounting base and magnetic mounting base. Note: For a complete list of product specifications, see the “Specification Sheet” and “Outline Drawing” at the end of this Manual.

  • Page 11: Standard Stud Mount

    Standard Stud Mount Procedure This mounting technique requires smooth, flat contact surfaces for proper operation and is recommended for permanent and/or secure installations. Stud mounting is also recommended when testing at high frequencies. Note: Do not attempt mounting on curved, rough or uneven surfaces, as the potential for misalignment and limited contact surface may significantly reduce the sensor’s upper operating frequency range.

  • Page 12: Adhesive Stud Mount

    Adhesive Stud Mount Procedure Adhesive mounting is often used for temporary installation or when the machine surface cannot be adequately prepared for stud mounting. Adhesives like hot glue or wax work well for temporary mounts; two-part epoxies and quick-bonding gels provide a more permanent mount. Note: Adhesively mounted sensors often exhibit a reduction in high-frequency range.

  • Page 13: Magnetic Mount

    Magnetic Mount Procedure Magnetic mounting provides a convenient means for making portable measurements and is commonly used for machinery monitoring and other portable or trending applications. Note: The correct magnet choice and an adequately prepared mounting surface are critical for obtaining reliable measurements, especially at high frequencies.

  • Page 14: Wiring

    Wiring On the following pages are eleven different wiring scenarios for the Smart Switch. The wiring legend below is applicable to all wiring diagrams. Figure 7 – Wiring Diagrams Legend For those wiring scenarios that suggest the use of an external electromechanical relay, IMI suggests Omron general purpose relays as listed below.
