PART 1 - GENERAL

1.1RELATED DOCUMENTS

  1. Drawings and general provisions of the Contract, including General and Supplementary Conditions and Division01 Specification Sections, apply to this Section.

1.2SUMMARY

  1. This Section includes motor control devices for use on AC circuits rated 600V and less.

1.3SUBMITTALS

  1. Product Data: For each type of controller include dimensions and manufacturer's technical data on features, performance, electrical characteristics, ratings, and finishes.
  2. Shop Drawings: For each motor-controller.
  3. Wiring Diagrams: Provide schematic wiring diagram for each type of controller.
  4. Qualification Data: For manufacturer.
  5. Field quality-control test reports.
  6. Operation and Maintenance Data: Include the following:
  7. Routine maintenance requirements for motor controllers and all installed components.
  8. Manufacturer's written instructions for testing and adjusting overcurrent protective devices.
  9. Overload-Relay Heater List and List of Settings: Compile after motors have been installed and arrange to demonstrate that selection of heaters and settings suits actual motor nameplate full load currents.

1.4QUALITY ASSURANCE

PART 3 - EXECUTION

3.1APPLICATIONS

  1. Select features of each controller to coordinate with supply circuit and motor; required control sequence; duty cycle of load; and configuration of pilot device and control circuit affecting controller functions.
  2. Use fractional-horsepower manual controllers for single-phase motors, unless otherwise indicated.

3.2INSTALLATION

  1. Locate controllers within sight of motors controlled, unless otherwise indicated.
  2. Fasten units to wall, mount on lightweight structural steel channels bolted to wall, or provide freestanding racks.
  3. Provide fuses in each fusible switch.

3.3IDENTIFICATION

3.4CONTROL WIRING

  1. Connect hand-off-automatic switch and other automatic-control devices where applicable.
  2. Connect to act through safety devices such as pressure and temperature cutouts, and motor overloads.

3.5FIELD QUALITY CONTROL

  1. Demonstrate product capability and compliance with requirements.
  2. Perform each test and inspection stated in NETAATS Sections 7.5, 7.6 and 7.16. Certify compliance.
  3. Correct or replace malfunctioning units and retest to demonstrate compliance.

3.6CLEANING
