Method for initializing a plug-in electric unit in a modular system applies to a base unit and plug-in electric units with modular electronics, storage for constant values and an interface between base unit and plug-in type units.

摘要

A variable resistor (VR) (31) fits in a feeder wire. First switching devices (33) separate storage for constant values (21) from a base unit (BU) (1). Second switching devices (34) separate modular electronics (22) from the BU. After a first waiting time beginning with the plugging-in of a plug-in type electric unit (2), the VR is steered ramp-fashion into its low-resistance state.
