METHOD FOR ELECTRICALLY CONTROLLING ELECTRICAL SUPPLY (S) OF ELECTRICALLY CONTROLLED SYSTEM (S), ELECTRICAL SUPPLY AND DEVICE FOR ELECTRICAL CONTROL THEREOF

摘要

The method involves measuring a representative electrical parameter, chosen from a voltage or current, at input and/or output terminals (1a, 2a) of an electrically controlled system (100) with variable optical properties. An automatic electric diagnostic of an alternative current or voltage supply is performed at the level of the system by comparing electrical parameter with given electrical setpoint. Data is sent for automatic electric diagnosis to be realized or realized automatic electric diagnosis, over a communication network e.g. controller area network. Independent claims are also included for the following: (1) an alternative current or voltage supply of electrically controlled system with variable optical properties or electrically controlled lighting system comprising a microprocessor (2) a device for electrically controlling an alternative current or voltage supply of electrically controlled system with variable optical properties or electrically controlled lighting system comprising a processing unit.
