  • Page 8: Construction

    1. Construction The Transfer Switches covered in this manual use molded case switches and/or circuit breakers to accomplish the transfer of two separate power sources to a single load. These molded case circuit breaker(s) and/or switch/switches, (molded case units), are interlocked via electrical and mechanical control systems.

  • Page 9: Description Of Operation

    2. Description of Operation The following are general descriptions of operation applying to the different styles of Transfer Switches. Certain accessory additions may modify the sequence of operations as required to suit specific applications. 2.1. Single Motor Operator The Single Motor ATS utilizes a single motor to operate both the normal and emergency molded case units.

  • Page 10: Dual Motor Operator

    2.2. Dual Motor Operator The Dual Motor Automatic Transfer Switch (ATS) operates in much the same way as described in section 2.1 Single Motor Operator with the exception that each molded case unit has its own motor operator. This allows the load to be disconnected from both the S1 and S2 power sources, offering the load a "Neutral / Off"...

  • Page 11: Installation

    The preceding sequence of operation describes the operation of a basic dual motor, ATS. Lake Shore Electric offers a wide variety of accessory equipment to meet customer specifications(s)/requirements(s). Please refer to the schematic diagram provided with your Lake Shore ATS for the specific controls provided. NOTE: For a UTILITY TO UTILITY (Dual Prime Source) application, a preferred source selector switch is provided on all transfer switches built for Utility-to-Utility applications.

  • Page 12: Table 3 - Automatic Transfer Switch Nomenclature

    Before bringing the power cables to the enclosure, be certain that the lugs will be of the correct size. If not, different sizes may be ordered from Lake Shore Electric. 1. Lug size and arrangements may vary depending on molded case switch manufacturer. 2.

  • Page 13: Figure 1 - Motor Slip Screws

    Once the transfer switch has been mounted to its installation location, perform initial start-up by following these steps: 1. Verify No Power from Any Source is Present. (a.k.a.: Utility, Generator or Other Source) 2. Place the "Control" key switch in the "Disable" position located on the door of the Automatic Transfer Switch (ATS).

    Additional Control Wire Installation: There are numerous accessories available on Lake Shore transfer switches which require external connections. Refer to the specific ATS unit’s schematic and layout "XXXXXX-03 and XXXXXX-04" drawings for additional connections which must be made. 3.2. Placing the Transfer Switch in Operation Before energizing the transfer switch electrically, be certain all external connections have been properly made according to the wiring diagram provided.
  • Page 16 7. If the voltage seen on the S1 or S2 menu screen is within the correct parameters for the source being viewed, the power cables are connected properly, and no shorting occurred, proceed to the next step. If problems occurred, please troubleshoot, as necessary. NOTE: Typically, voltage should only be available from one of the sources at this time.
