EDI launches new MMU2 SmartMonitor series

Recently launched by Eberle Design (EDI) the MMU2-16LEip and MMU2-16LE SmartMonitors fully comply with the recently updated NEMA TS2-2003 (R2008) Standard for Traffic Controller Assemblies, Amendment No. 4-2012. This new standards update defines Flashing Yellow Arrow (FYA) operation for both the controller unit and the MMU. EDI says it is also very proud to be the first MMU manufacturer to be fully conformant to the new NEMA standard and MUTCD requirements. The new SmartMonitor series is designed to monitor

Recently launched by 41 Eberle Design (EDI) the MMU2-16LEip and MMU2-16LE SmartMonitors fully comply with the recently updated NEMA TS2-2003 (R2008) Standard for Traffic Controller Assemblies, Amendment No. 4-2012. This new standards update defines Flashing Yellow Arrow (FYA) operation for both the controller unit and the MMU. EDI says it is also very proud to be the first MMU manufacturer to be fully conformant to the new NEMA standard and MUTCD requirements.

The new SmartMonitor series is designed to monitor an intersection with up to four approaches using the four section FYA movement outlined by the MUTCD 2009. For monitoring purposes an FYA approach is logically defined as a four input channel consisting of the solid red arrow, solid yellow arrow, flashing yellow arrow (permissive), and solid green arrow (protected). Twelve cabinet modes are now supported in the SmartMonitor providing configuration choices based on the number of load switches provided and the capabilities of the controller unit. In all modes the new MMU2-16LEip and MMU2-16LE SmartMonitors have been designed to provide the same broad fault coverage for the FYA approaches as it does for conventional protected left turn phases including conflict, red fail, dual indication, and both minimum yellow and minimum yellow plus red clearance monitoring.

The MMU2-16LE SmartMonitor series includes a built-in setup wizard to quickly and accurately configure the monitor programming parameters simply by answering a short series of questions related to the intersection geometry and cabinet wiring. The built-in context sensitive help system and patented diagnostic wizard then automatically pinpoints faulty signals, providing technicians with an unprecedented amount of assistance and data feedback quickly with a push of the help button. The SmartMonitor menu driven operation presents signal voltages, data logs and vital cabinet information displayed directly on the SmartMonitor front panel displays. These advanced capabilities will increase the operational level of safety of the intersection and enhance the diagnostic features available.

The Final Rule edition of the FHWA MUTCD 2009 manual included revised Sections 4D.17 thru 4D.24, with new sections and figures for modes of left-turn and right-turn signal operations. This development left users and equipment manufacturers with a need for an updated NEMA equipment standard in order to have equipment interchangeability and interoperability when deploying intersections using the flashing yellow arrow signals. The recent standards update from NEMA provides a number of improvements to the TS2-2003 version. Most important is the long awaited Flashing Yellow Arrow operation. Equipment standards such as NEMA TS-2 are vital to users to ensure that traffic control equipment is both interchangeable and interoperable and thus provides a long service life.
