Elevator - 5 Levels

An elevator connecting 5 levels of a building.

Switches:

Red: power
Blue: elevator
Black: activating levels
Yellow: deactivating levels

You can choose the level you want to go to by using a terminal:

* step 1: activate one of the 'AA SB Level ... On' switch boards.
* step 2: lock the corresponding rotating joint ('AA R-joint Level ...')

Start the elevator by activating the 'A SB Elevator' switch board. To go down again just deactivate.

It is advisable to reset the elevator after use by following this procedure:

* step 1: unlock the locked rotating joint.
* step 2: deactivate the 'AA SB Level ... On' switch board you used.
* step 3: activate the corresponding 'AA SB Level ... Off' switch board.
* step 4: deactivate that same switch board.

Now the elevator is ready for the next use.

Sadly you always have to start from level 0. E.g. when you want to go from the third to the first floor, you have to go to the ground floor and reset the elevator before being able to choose first floor.
