Patent Images
1. A system for facilitating a remote Lock Out/Tag Out (LO/TO) procedure on a machine, the system comprising:
- a first wireless control device resident in the machine, the first wireless control device being configured to sense a state of the machine including positional data for the machine, and to provide a user interface to an operator of the machine; and
a second wireless control device remote from the first wireless control device, the second wireless control device being configured to provide a user interface to a service technician located at a distance that is remote from the machine and to wirelessly interface with the first wireless control device such that the service technician is able to remotely perform a LO/TO procedure on the machine only if the machine is in a proper location required for machine maintenance to be undertaken.

Abstract
A remote lock-out/tag-out system and method allow a remote service technician to remotely lock-out a machine via a remote wireless control device. In one aspect, the lock-out initiation request is sent from the remote wireless control device to the machine. The remote wireless control device then receives from the machine an indication that the machine location and state are suitable for lock-out. In response, the remote wireless control device sends a lock-out command to the machine.

8. A method for executing a remote LO/TO procedure with respect to a machine via a remote wireless control device, the machine having therein a local wireless control device, the method comprising:
-
receiving a request at the remote wireless control device input by a remote service technician to initiate LO/TO of the machine; transmitting a request to initiate LO/TO from the remote wireless control device to the local wireless control device and displaying a corresponding initiation request to an operator of the machine via the local wireless control device; receiving an indication from the local wireless control device at the remote wireless control device of positional data for the machine and a machine state for LO/TO; and locking out the machine to the operator only in response to determining at the remote wireless control device that the machine is in a proper location required for maintenance of the machine to be undertaken and the machine is in a safe state for LO/TO. - View Dependent Claims (9, 10, 11, 12, 13, 14)
