The elobau motion detector is designed for monitoring motion to ensure safe setup and operation of a machine but also allows safe access to the machine after the machine has been idle. In typical operation, while the machine is in use, the rotational portion of the machine function is monitored via sensor (pulse) feedback to the zero speed monitor. If the pulse feedback is above a specified (through switch or terminal settings) threshold, the output of the unit will indicate to the safety... (read more)
