Abstract:
An electronic control device for integration into mechanical systems is described and provided with an operating program hierarchically broken down into a plurality of program levels. Some of the program levels are non-reprogrammable and some are reprogrammable. In this manner the flexibility of the electronic control device is greatly enhanced.
Abstract:
A programmable timeswitch comprises a microcontroller and a switching relay for controlling the supply of electricity to electrical apparatus in accordance with a predetermined `yearly` program stored in an EPROM. The yearly program can include different daily programs for weekdays and weekends and includes different seasonal programs to take account of different demands for electricity at different times of the year. The timeswitch is programmed to switch automatically from one seasonal program to the next seasonal program on predetermined dates in the year and so does not have to be re-programmed at intervals throughout the year. The timeswitch may be used as part of a `deferable load program` run by a utility in which a large number of timeswitches are supplied to different installations, the timeswitches having been programmed by a master console under the sole control of the utility.
Abstract:
A device may be configured for updating the programming of a control system of an electric rotary machine, the device having no screen. The device may include an electrical or optical connector element for connection to the control system, enabling data to be transferred between the device and the control system and a memory for containing data to be transferred into the control system and/or for loading data from the control system. The device may include a control member, with data being exchanged between the device and the control system in response to an action exerted manually on the control member.
