Abstract
The present invention relates to a method for synchronizing the optical units of a photoelectric barrier and to such a photoelectric barrier. The synchronization method comprises the steps of transmitting radiation forming a synchronization signal from a first optical sender of the first optical unit; controlling a plurality of the optical receivers of the at least one second optical unit to monitor whether the synchronization signal has been received and performing a synchronization step if the synchronization signal has been received. The method further performs the step of defining at least one of said plurality of optoelectronic components to be used for the synchronization step.
