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.

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
Transfer Load - test with load with time delays
No Transfer - test without load, generator start only
Controller Power Supply utilizing the Universal Transformer Assembly (UTA) - provides 170Vdc to the controller and 24Vdc ungrounded to the power relays. The UTA also provides line voltages from 120Vac to 600Vac via an internal six position jumper array, 120Vac UPS input and 24Vdc input battery options.
Dual processor based with dedicated processor for high speed Serial or Ethernet connections
All signal in / out relays are isolated via DIN Mounted relay / terminal blocks
Elevator pre-signal contacts
Power quality metering
Elevator pre-signal
