  • Page 5: Related Documentation

    Related documentation The VISY probes have to be connected with the VISY-Command central unit which is mounted inside the petrol station building. Before operating, the VISY-Command must be configured us- ing a PC or notebook and the VISY-Setup software application. The VISY-Command collects data from the sensors and transmits this to a higher-level system (e.g.

  • Page 6: Requirements For Service Engineers

    The complete VISY-X system should only be installed by trained service engineers. Safety instructions The VISY-X system is optimised for use in petrol stations and is compatible with all commercially available fuels. It serves to measure and evaluate the filling levels in tanks. The system must be used exclusively for this purpose.
