Abstract
The trip device comprises a processing unit which gives a tripping order according to the value of the current supplied by current sensors, and to threshold and time delay values defined by setting devices. The setting devices connected to the processing unit comprise multiple contacts. The contacts supply an encoded binary value representative of each position of the setting device. To prevent operating errors between two positions, only one of the contacts changes state between two successive positions. The value supplied by the setting device is the value corresponding to the immediately lower position or to the immediately higher position. The code representative of each position can follow, for example, the order of GRAY encoding.
