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.
