Controls
Since all the equipment of the locks is operated electrically, the whole process of locking a ship up or down can be controlled from a central control room, which is located on the centre wall of the upper flight of locks. The controls were designed from the outset to minimise the chances of operator error, and include a complete model of the locks, with moving components which mirror the states of the real lock gates and valves. In this way, the operator can see exactly what state the locks and water valves are in.
Mechanical interlocks are built into the controls to make sure that no component can be moved while another is in an incorrect state; for example, opening the drain and fill valves of a lock chamber simultaneously.

Famous quotes containing the word controls:
“If the Party could thrust its hand into the past and say of this or that event, it never happened—that, surely, was more terrifying than mere torture and death. ... “Who controls the past,” ran the Party slogan,”controls the future: who controls the present controls the past.””
—George Orwell (1903–1950)
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
“Comparatively, we can excuse any offense against the heart, but not against the imagination. The imagination knows—nothing escapes its glance from out its eyry—and it controls the breast.”
—Henry David Thoreau (1817–1862)
