Abstract:
A machine, specifically a pump, a compressor, an agitator or a hoist, includes at least one motor and one machine protection circuit that includes a measurement device having at least one sensor for monitoring at least one parameter of the machine and includes an analysis device for analysing the parameters measured by the sensor and for activating a machine protection relay for switching off the machine. A switch cabinet positioned away from the machine is provided, and the machine protection circuit is spatially separated by the measurement device being arranged in the machine, and by the analysis device and the machine protection relay being arranged in the switch cabinet.
