Overview

The MX350 controller is specifically designed for low voltage Automatic Transfer Switch (ATS) applications. The flexible control and communications options are ideal for any application. Integrated push buttons, graphical controls and LED indicators reduce external components and wiring in addition to providing local control and access to system information. Multiple communication protocols allow simple integration into monitoring and control systems.

Graphical Control Panel

interface provides local control and access to system information. Automation FlexLogic� with interlocking and programmable logic control

The MX350 microprocessor

is standard with the entire CTE product family

  • Features and Benefits

    • Dual Communications
      Built-in RS-485 serial and 10/100 base-T Ethernet
      Open protocols - Modbus RTU and Modbus TCP
    • Available to support Open, Closed and Delayed Transition
    • Small footprint
    • Graphical control panel
    • Multiple communication protocols
    • ¼ inch VGA color graphical display with embedded HELP menus
    • Status LED's indicating:
      ALARM - indicating a problem with the ATS or a user configured alarm condition is active
      TD DELAY - indicating the controller is timing before taking the next control action
      XFER INHIBIT - indicating the controller will not transfer to the other source without operator intervention
      SOURCE 1(S1) AVAILABLE LED - indicating power is present per user setpoints
      SOURCE 2 (S2) AVAILABLE LED - indicating power is present per user setpoints
      SOURCE 1 (S1) STATUS LED - indicating load is connected to S1 power
      SOURCE 2 (S2) STATUS LED - indicating load is connected to S2 power
    • User-Configurable setpoints for inputs and Outputs
    • Field modification of control features
    • Plant exerciser clock for 1 day, 1 week, 14 days, 28 days or 365 days. The time base of 365 days permits up to 24 events to be scheduled and the other time bases permit up to 24 events.
    • SYSTEM TESTS
      Fast Test - test with load, no time delays
