Abstract (en)
[origin: EP2687418A2] The box (10) has a LED unit (12) for creation of a light signal, and an interface (14) for integration of the box into a signaling system. The interface comprises a characteristic curve replication unit (22) for creation of a determined current and voltage behavior of the box. The interface comprises a logic unit (16) and a separate configuration memory (18), where parameters for adjusting the current and voltage behavior to a given voltage behavior are stored in the memory. The logic unit controls the characteristic curve replication unit based on the parameters stored in the memory. The parameters are selected from a group consisting of day/night switching parameters, plausibility parameters of a driving voltage, plausibility parameters of a power supply, simulation parameters of a known distance signal lamp i.e. route signal bulb, day/night parameters for an LED supply, minimum or maximum parameters for LED current monitoring, minimum or maximum parameters for LED voltage monitoring, error response parameters for determining an error response behavior of a logic unit and/or parameters used in the LED unit.
