Valve controller, configuration method therefor and valve arrangement

摘要

A valve arrangement (1) defines a fluid inlet (7) and a fluid outlet (8), and comprises a valve controller (2) for controlling a fluid flow between the fluid inlet (7) and the fluid outlet (8). The valve controller (2) comprises control electronics and is configured to operate as an AS-interface slave when connected, by a cable (40), to an AS-interface system. A manipulation unit (38) is permanently affixed onto a housing (28) of the valve controller (2) to enable manual entry of a setting of a control parameter for an AS-interface chip (37), which is located in the housing (28) to handle data communication between the valve controller (2) and the AS-interface system. A data processor (35) is connected to the manipulation unit (38) so as to identify the setting and transmit one or more dedicated control commands to the AS-interface chip (37) in correspondence with the setting.
