MX200 (Microprocessor Controller)
GE Zenith Controls MX200 advanced microprocessor
controller is designed for the most demanding transfer
or bypass switch applications. It may be specified with
standard options or programmed to use any or all of the
most commonly used options for today's transfer switch
operation. It also may be equipped with our ZNET200
remote communication interface for use with
annunciators, modems or PC control.
The MX200 manages switch operation via a convenient
touchpad that provides indication setting and
diagnostic capabilities. As an embedded digital
controller, the device offers high reliability and ease of
unattended operation across a range of applications.
The GE-Zenith MX200 (Microprocessor offers the
following features:
• Multipurpose display: LEDs for continuous
monitoring of switch position and source
availability; a four-line by 20-character, backlit
LCD display for settings, functions,
programming and annunciation
• Through-the-door programming and display
• Simplified keypad entry—menu-driven system
is designed for ease of use
• Built-in diagnostics with displays for ease of
troubleshooting
• Passcode protected to limit user access
• Timer countdown display for ease of operation
• User settings unaffected by power outages
• Wide range of accessories and configurations
available for the most demanding applications
Design and Construction Features
• Close differential three-phase under-voltage
sensing of the normal source—factory standard
setting 90% pickup, 80% dropout (adjustable);
under-frequency sensing of the normal source
factory setting 95% pickup (adjustable)
• Voltage and frequency sensing of the
emergency source—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 the emergency source fail
• Type 1 enclosure is standard; also available in
open style or Types 3R, 4 or 12
• Double-throw, mechanically interlocked
contactor mechanism
• Electrically operated, mechanically held
• Designed for emergency and standby
applications
Generator PLC (Series 90-70)
The Generator PLC is configured in such a way that
Master PLC has all the information of all the 16
Generator Parameters.
The Generator PLC offers the following features:
Metering and Monitoring
• Metering: A, V, W, var, Hz
• Generator Parameters
• Paralleling Switch gear parameters
Electronic Power Meter EPM 7330
The EPM 7330 gives you all the high-accuracy
measurements of the EPM 7300, plus on-board data
storage, setpoints, standard digital I/O and an optional
Ethernet port and optional built-in modem either of
which can be used as a gateway to as many as 31 serial
devices.
