Our MPT series is available in both open and closed transition options. As you may know, Wye-Delta controllers require six leads from the motor to the controller. These leads are connected by the controller first in the Wye configuration which draws 33% of normal starting current and develops 33% of normal starting torque. After a short time delay, the controller then connects the motor winding in a Delta configuration, applying full voltage, drawing full load running current and developing full running torque. Only the highest quality components, UL Listed or Recognized, are used throughout to assure the best possible reliability. Our cabinets are fabricated from heavy 12 gauge reinforced steel, with Type 3R supplied as standard and rated 60°C. All field wiring and service connections may be made from the front, allowing the controller to be mounted flush against a wall. Metron fire pump controllers conform to the latest requirements of the NFPA 20, UL 218 and FM 1321/1323, and bear the labels of Underwriters Laboratories and Factory Mutual. Metron controllers are completely wired, assembled, and tested at the factory before shipment and ready for immediate installation. These controllers are also suitable for use as service entrance equipment.
Let Metron’s “Pilot” feature guide you through the controller’s startup settings. The “Pilot” feature automatically guides the user through the settings required at start up. Searching through multiple menus to locate settings is eliminated. “Pilot” appears on the touch screen on initial power up, or by pressing the “Pilot” Icon. The system will also perform a self-test upon power up to ensure proper functionality.
The MPT Series also features a large 7” color LCD touchscreen that simultaneously displays 3 phase amperage/voltage, system pressure, start pressure, stop pressure, system status, alarm status, date and time. The screen also includes icons for Pilot/Quick Start, System Set Points, User Settings, Data Log, Diagnostics, and others for ease of installation and data log/event history retrieval. Monitoring of the PC board inputs/outputs through the touch screen is possible, as well as selecting the phase rotation, language selection and Modbus communication protocol (vis RD485 port).
The Microprocessor-based logic also includes a low battery indicator, a real time/date clock that is accurate to plus or minus two minutes per year over the full temperature range and is capable of running 7+ years without AC power. The on-board data log memory can store up to 18 months of event history (approx. 112,000 events), and over 10 years of event history with a 2G USB Flash Drive that is accessible without opening the panel. The event history can be viewed by scrolling on the display or by saving it to a USB flash drive. The event history is recorded as a .CSV file and can be easily opened as an Excel file. For additional security, multi-level password protection is also available.
The controller includes as standard six (6) discrete auxiliary inputs and six (6) outputs. These auxiliary I/O are in addition to those required by NFPA 20 UL and FM. All auxiliary I/O can be field programmed on the touch screen. Expandable 12 channel I/O board for additional alarms, expandable to 168 I/O. All 48 aux programs can have a custom message
Each record tracks:
- Date and Time
- Voltage and current for connected source
- Login state
- Internal temperature
- State of every alarm
- The I/O state of all PCB’s (excluding any add-on boards).
- Active start conditions.
- The state of all aux programs (48 aux programs available).
- Power available
