MX150 Microprocessor Controller

OVERVIEW

The MX150 microprocessor is standard with the CTG product family. The MX150 microprocessor panel controls the operation and displays thes tatus of the transfer switch's position, timer sand available sources. As an embedded digital controller, the MX series offers high reliability and ease of unattended operation across a range of applications.

BENEFITS

Features and Benefits

Digital timer and adjustments with 1 second resolutionLong lasting LED indicators and an easy-to-view LCD displayInputs optoisolated for high electrical immunity to transients and noiseDigital voltage and frequency adjustments with1% resolutionVoltage and frequency sensing includes: –Voltage imbalance detection between phases–Under frequency sensing on source 2–3 Phase under voltage sensing on source 1(S1)– Normal and single phase sensing onsource (S2)– EmergencyModular pre-signal option easily integrated into the system (e.g. elevator pre-signal and motor load disconnect)Universal Motor Disconnect (UMD) available for programming to pre-signal, post-signal or bothLine voltage transients are isolated from the control board using remote transformersSimplified major components and modules for easy replacementOn-board diagnostics including voltage frequency, control and timingNonvolatile memory – battery backup not required during normal source outageExternal communication available through LonWorks/ModBus network interface (RS232,RS 422, and RS 485 are also available)Maintained and momentary test positions are available to the controllerTest mode allows manual bypass of all transfer timers when applicableAutomatic daylight savings adjustment available

User-Friendly Operation

LEDs for continuous monitoring of switch position, source availability, exercise time delay operation and diagnosticsSimplified adjustment for voltage, frequency and time delay settingsClose differential 3 phase under-voltage sensing of source 1, factory standard setting 90% pickup,80% dropout (adjustable); under-frequency sensing of the source 1 factory setting 95% pickup (adjustable)Voltage and frequency sensing of source 2,factory standard setting 90% pickup voltage,95% pickup frequency (adjustable)Test switch (fast test/load/no load) to simulate normal source failure – automatically bypassed should source 2 fail
