  • Remote control apparatus having emergency stop feature with redundancy, and associated method
    Patent number: 9524637
    Abstract: A remote control apparatus is usable to remotely control another device and includes a base unit that is electrically connected with the device and further includes a remote control unit that is remote from the device and that is usable to control the device. The remote control unit includes an emergency stop switch that simultaneously actuates two switches that are electrically independent of one another. A primary control apparatus monitors one of the switches, and a secondary control apparatus monitors the other switch. If either switch is moved from its CLOSED state to its OPEN state, the corresponding control apparatus will take emergency actions. The primary and secondary control apparatuses additionally monitor the switches and perform the aforementioned emergency actions in the event of a fault with one of the switches or on the associated wiring.
