Stilstand & hastighedsovervågning

In accordance with the new machinery directive, the operating condition of a drive must be safely monitored and maintained during its shut-down. Typical applications are the release of locking mechanisms after the standstill of dangerous movements has been detected as well as work with open safety devices and reduced speed during calibration of the machine. The new speed monitors of the SAFEMASTER S series detect and signal the standstill and overspeed of machines and systems in automatic as well as set up operation. Its safely integrated safety door monitoring additionally provides a higher productivity and a higher degree of safety for the operating personnel.
