CMS Zero Speed Control

The Model CMS 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 two separate circuits, one for machinery shutdown and one for an alarm.

The Model CMS provides a means of protection to prevent compound damage from inoperative or failed equipment due to a lack of rotation.
