<p>The ballast has a microprocessor (102) and a connection to connect a supply voltage (U N). The microprocessor is designed to combine signals at two connections, for producing a combination signal. The electronic ballast (100) has a table, in which a desired range of the combination signal is discarded. The microprocessor is further designed to evaluate the actual value of a combination signal with the corresponding desired value range of the combination signal.</p> |
