Abstract

This disclosure relates to various embodiments of lockout relay devices. In one embodiment, a lockout relay device may transition between a closed position and a lockout position in response to an action of a deck device. The lockout relay may further be configured to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation. A manual actuator may permit a manual transition of the lockout relay device from the closed position to the lockout position and from the lockout position to the closed position. A lockout mechanism may be configured to cause the lockout relay device to transition to the lockout position in response to the force generated by the deck device. The lockout relay device may remain in the lockout position until the occurrence of one of a manual adjustment and a reset operation.

Dependent claims

A lockout relay device configured to transition from a closed position to a lockout position in response to an action of a deck device, and to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation, the lockout relay device comprising:

a rotary shaft configured to be rotated between a first rotational position corresponding to the closed position and a second rotational position corresponding to the lockout position;
at least one deck device in contact with the rotary shaft and configured to exert a force on the rotary shaft in response to a fault, the force configured to cause the lockout relay device to transition from the closed position to the lockout position;
a manual actuator coupled to the rotary shaft and configured to permit a manual transition of the lockout relay device from the lockout position to the closed position;
a linear actuation component configured to initiate a reset operation by generation of a linear motion;
a lockout mechanism configured to translate the linear motion of the linear actuation component to a rotational motion of the rotary shaft and to cause the lockout relay device to transition from the lockout position to the closed position, the lockout mechanism comprising:
a coupling component affixed to the linear actuation component;
a protruding component extending from the coupling component;
a rotational arm coupled to the rotary shaft;
wherein the linear motion causes the protruding component to exert a force on the rotational arm, and the force results in rotation of the rotary shaft from the second position to the first position.
