2.6.5 Logic interface connection
Refer to «3.11.1 Schematics» for wiring information.
2.6.6 Service port connection
The service port (connector: SERVICE) allows to connect the valve to a RS232 port of a computer.
This requires a service cable and a software from VAT. You can either use our freeware 'Control View' or purchase our
'Control Performance Analyzer'.
The service port is not galvanic isolated. Therefore we recommend using this only for setup, testing and maintenance and
not for permanent control.
Refer also to «3.1.1 Local operation» for details and to «7 Spare parts and accessories» for ordering numbers of service
cable and software.
