Abstract
A method for consigning a function of an electrical device includes: a) receiving a request to consign a function implemented by a sub-assembly of the electrical device, the request being transmitted by a client terminal connected to the control unit via a short-range communication link; b) generating a digital key including a unique identifier; c) storing one copy of the generated key in a memory of the control unit and sending another copy of the generated key to the client terminal that transmitted the request; d) consigning the function so as to prevent this function of the device from being used by the control unit as long as the consignation is active.
Claims15
A method for locking out a function of an electrical device, comprising:
- a) receiving, by an electronic controller of the electrical device, a request to lock out a function implemented by a sub-assembly of the electrical device, the request being transmitted by a client terminal connected to the electronic controller via a short-range communication link, the electrical device including one of an electrical protection device, an electrical measurement device, or an electrical switching device;
- b) automatically generating, by the electronic controller, a digital key comprising a unique identifier of the client terminal and a connection identifier corresponding to a user requesting to lock out the function implemented by the sub-assembly of the electrical device;
- c) storing one copy of the digital key in a memory of the electronic controller and sending another copy of the digital key to the client terminal that transmitted the request;
- and
- d) locking out the function, by a digital lock module of the electronic controller, to prevent said function of the device from being used by the electronic controller as long as the lockout is active,
- wherein the locking out of the function is lifted based on receipt of a request including a digital key that matches the one copy of the digital key stored in the memory of the electronic controller and based on no other digital key copies being stored in the memory of the electronic device, the locking out of the function being maintained if there is at least one other digital key copy stored in the memory of the device.
An electrical device, comprising:
- a sub-assembly configured to perform a function;
- and
- an electronic controller configured to:
- a) receive a request to lock out the function implemented by the sub-assembly, the request being transmitted by a client terminal connected to the electronic controller by a short-range communication link;
- b) automatically generate a digital key comprising a unique identifier of the client terminal and a connection identifier corresponding to a user requesting to lock out the function implemented by the sub-assembly of the electrical device;
- c) store a copy of the digital key in a memory of the electronic controller and send another copy of the digital key to the client terminal having transmitted the request;
- d) lockout the function, by a digital lock module of the electronic controller, to prevent use of said function of the device by the electronic controller as long as the lockout is active,
- wherein the lock out of the function is lifted based on receipt of a request including a digital key that matches the one copy of the digital key stored in the memory of the electronic controller and based on no other digital key copies being stored in the memory of the electronic device, the locking out of the function being maintained if there is at least one other digital key copy stored in the memory of the device, and
- the electrical device includes one of an electrical protection device or an electrical measurement device or an electrical switching device.
