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.
