摘要:
The invention relates to a device for monitoring operational parameters of installations which have an electric or electronic control unit and a control panel for displaying and inputting the operational parameters, in addition to a microprocessor unit. Said microprocessor unit is connected via a data bus line to a non-volatile memory for storing and documenting the supplied input data and/or measured value data of the operational parameters. The data can be read out of the non-volatile memory using a service unit which can be connected to the microprocessor unit by means of an interface and can be stored in said service unit.
摘要:
The invention relates to a control system (1) for light regulating devices such as blinds or shades. The control system comprises a control unit (6,6') for connecting to a motor drive (7) of a light regulating, device. The control unit comprises a first input (18) for receiving motor control data along a data supply line (9,9'). A second input (17,26,26') is provided for receiving decentralised user commands for altering the position of the light regulating device. The control system is characterised in that the control unit (6,6.), by means of an external command input (25') can be set into either a slave mode in which data can only be received or into a master mode in which data can be received and transmitted along the data supply line (9,9'). Hereby any light regulating device can be selected as a master device for controlling the blinds in the same group. Preferably the command input of the control unit comprises a manually operatable switch such as a dip switch.
