Abstract
An apparatus includes a number of apparatus components that are operable to produce an apparatus action. The components include a circuit board that is available for installation in a number of different board variants. Each circuit board variant includes a photoelectric barrier that receives an input signal from a controller of the apparatus, and that generates a photoelectric barrier output signal supplied to the controller. At least one of the circuit board variants includes a delay element that introduces a delay into the output signal from the controller that is supplied to the photoelectric barrier. The delay is matched to the particular variant of the circuit board, so that the controller, by detecting a characteristic of the delay, can identify the circuit board variant of the currently-installed circuit board. The controller then controls the components to produce the apparatus action dependent on the variant of the currently installed circuit board.
