What does interlock mean?
Interlock (engineering) An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. It may be used to prevent undesired states in a finite-state machine, and may consist of any electrical, electronic, or mechanical devices or systems. In most applications, an interlock is used to help prevent a machine…
How does a safety interlock work?
In order to safely transfer the power source from a generator (and back to main), a safety interlock is often employed. The interlock consists of one or more switches that prevent both main power and generator power from powering the dwelling simultaneously.
What is an interlock on a generator?
Electrical. An interlock device is designed to allow a generator to provide backup power in such a way that it (a) prevents main and generator power to be connected at the same time, and (b) allows circuit breakers to operate normally without interference in the event of any overload condition.
What is an interlock on an elevator?
Elevators are equipped with an interlock that prevents the moving elevator from opening its doors, and prevents the stationary elevator (with open doors) from moving.
What is interlock knit?
It’s a variation of a rib knit and it’s similar to jersey knit, but it’s thicker; in fact, interlock knit is like two pieces of jersey knit attached back to back with the same thread.
How do interlock devices work?
In some cases, interlocks can be purely mechanical, such as in firearms’ internal safety, preventing firing pin release if the chamber is not closed properly. In device operations such as hand-fed cutters and pressers, the utilization of interlocks or buttons to activate the device lessens the possibility of causing harm to its operator.
What is a two-part interlock system?
A similar two-part interlock system can be used anywhere it is necessary to ensure the energy supply to a machine is interrupted before the machine is entered for adjustment or maintenance. In microprocessor architecture an interlock is hardware that stalls the pipeline (inserts bubbles) when a hazard is detected until the hazard is cleared.
