A switch or other device that prevents activation of a piece of equipment when another piece of equipment is operating.
An electrical or mechanical device that will not allow the machine to cycle if not in the correct position. i.e.- The turret on a rotary machine will not index unless the safety light curtain, cooling tank (if used), dip tank, oven doors, primer tank (if used), or safety gates are not in the correct position. An interlock screen on the HMI shows what interlocks are active.
Hoistway-door interlock is a device having two related and interdependent functions: 1) to prevent the movement of the elevator by the normal operating device unless the hoistway door is in the closed position; and 2) to prevent the opening of the hoistway door from the landing side unless the car is within the landing zone and is either stopped or is being stopped.(empty)(empty)
An arrangement whereby the operation of one control or mechanism allows, or prevents the operation of another. (R15.06)
A device having two related and interdependent functions which are: (1) to prevent the operation of the driving machine by the normal operating device unless the hoistway door is locked in the closed position. An electro-mechanical device that prevents operation of an elevator unless the hoistway doors are in the closed and locked position; (2) to prevent opening of a hoistway door from the landing side unless the elevator is in the landing zone and is either stopped or being stopped.
Safety device used to open circuit and disable machine when doors or covers are open. Make sure that this safety measure is not defeated. Sometimes they are jumped out.
a device actuated by the operation of some other device with which it is directly associated, to govern succeeding operation of the same or allied devices
a device that is installed in your car that is about the size of a cell phone with a mouthpiece on it
a device that operates to prevent the operation of machine while the cover or door of the machine is open or unlocked, and which will also hold the cover or door closed and locked while the machine is in motion
a device that prevents one action being taken until a certain condition is satisfied
a device that uses one electrical load to control the operating time of another electrical load
a hardwired connection between two systems or mechanisms that provides time-critical safety information
A specific switch designed to shut down an apparatus (like a door being opened or a lid raised) for safety and to avoid personnel injury.
A device that prevents a machine from initiating an operation until a condition or set of conditions is fulfilled.
A device to prevent lift movement when a landing gate is not fully closed and to prevent the landing gate from being opened unless the lift platform is present at that landing.
a device or set of devices that insures the proper sequence of actions occur. Most cars have interlocks to insure certain aspects of proper operation. The key must be inserted before the steering wheel will turn or the transmission shifted into gear. The key cannot be removed until the car is put in park.
An arrangement whereby the operation of one control or mechanism brings about or prevents the operation of another.
Hardware or software function that prevents succeeding operations when specific conditions exist.
A device to prove the physical state of a required condition and to furnish that proof to the primary safety control circuit.
A safety device designed to insure that a piece of apparatus will not operate until certain precautions have been taken.
An electrical-circuit arrangement that prevents a second operation from taking place until the first operation is completed.
1. To connect or be connected by fitted parts. 2. To be connected so that neither part can be operated without the other. 3. Electrical circuit used to block an action until certain conditions have been met.
Interlocking is a method of preventing undesired states in a state machine, which in a general sense can include any electrical, electronic, or mechanical device or system.
