Description

At the top of the panel is a vertical row of four indicator lights. These lights show the four floors that can be reached in the Castle tower. The floors that can be reached are as follows:

At the bottom of the panel is a circle of eight lights with a red reset button in the middle. The lights have a series of lines connecting them together in various patterns. There are two small lightbulbs missing in the circle of eight lights.
Each floor has a certain pattern of lights that has to be entered into the circle of lights arrangement. When a certain pattern of lights is entered on the control panel the Elevator will go to that floor.

Tasks

Task 1 - to find the four patterns that will move the Elevator to all four floors.
Task 2 - find the missing Small Lightbulb (3-pin).
Task 3 - use the correct circle pattern to get to the Lobby at the top of the tower.
Task 4 - find the missing Small Lightbulb (2-pin).
Task 5 - use the correct circle pattern to get to the Cellar at the bottom of the tower.

Solution

Task 1 - The four patterns are drawn in chalk on the wall of the Elevator next to the control box. The top pattern is hidden by a leaf of the large pot plant. Josef can move the leaf to see the pattern (a five-pointed star)
Task 2 - Josef will have to take some soil out of the pot of the large pot plant and drop the soil on the floor. A Maintenance Robot will come out of a small access door and vacuum up the soil. If the player makes Josef pick up the Maintenance Robot he will shake the Maintenance Robot and the Small Lightbulb (3-pin) will fall out. The Small Lightbulb (3-pin) should be placed in the circle of lights on the control box panel.
Task 3 - the five-pointed star pattern should be entered into the circle of lights. This will make the Elevator travel to the Lobby at the top of the tower.
Task 4 - four new game Levels will have to be completed before the Small Lightbulb (2-pin) can be obtained. They are:

After completing the two Mini-games in the Castle Level, the Mayor of Machinarium will give Josef the Small Lightbulb (2-pin). Josef should then return to the Elevator to complete this Elevator Control Box Puzzle mini-game. The Small Lightbulb (2-pin) should be placed in the circle of lights on the control box panel in the Elevator.
Task 5 - the eight-pointed star pattern should be entered into the circle of lights. This will make the Elevator travel to the Cellar at the bottom of the tower.
