Abstract
An elevator overspeed system designed to work as a governor includes a first switch responsive to an overspeed condition and a second, remotely located switch responsive to said first switch. An overspeed elevator control procedure is initiated when one of the first or second switches are tripped. The first switch is automatically re-set after the second switch is tripped. The second switch is manually re-set to re-start the elevator system in normal operation mode.
