Electronic motor manager
The Contactron Electronic Motor Manager (EMM) by Phoenix Contact converts the motor into a sensor and allowes the user to set parameters for dangerous operational conditions
Phoenix Contact’s Contactron Electronic Motor Manager (EMM) monitors the effective power consumed by motors. The EMM uses this data to analyze errors and provide early warning to the controller, helping to increase system availability.
The EMM converts the motor itself into a sensor. The user can set the parameters to detect dangerous operational conditions, such as overload, underload, pollution and wear. The module provides advanced diagnostics and allows the user to make informed decisions for predictive maintenance and better operation. In a worst case scenario, the EMM can shut down the motor to protect the system.
The EMM’s onboard inputs and outputs facilitate direct control of motor starters. It provides easy-to-understand remote indication of system problems. The 22.5-mm module has selectable tripping curves of class 10 to class 30, for full three-phase motor protection. Up to 16 EMMs can be controlled with a single Profibus gateway, reducing costs, space and wiring time.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
