The Model CMS-1G+CMS-K is a direct drive control that indicates when rotating equipment has ceased to turn. The output contacts of the Model CMS can control up to 2 separate circuits, 1 for machinery shutdown and 1 for an alarm. The unit can be programmed as an overspeed, under speed or zero speed device. The Model CMS provides a means of protection to prevent compound damage from inoperative or failed equipment due to a lack of rotation.
