Electronic Motor Manager Improves Predictive Maintenance
The Contactron Electronic Motor Manager (EMM) precisely monitors the effective power consumed by motors and uses this data to analyze errors and provide early warning to the controller, helping to increase system availability.
The device 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 unit can shut down the motor to protect the system. For example, the unit could detect a clogged filter in a pump, preventing dangerous dry running conditions. The unit'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 motor managers can be controlled with a single Profibus gateway, reducing costs, space and wiring time.
