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 software from VAT.
You can use our Software (freeware) 'Control Performance Analyzer' which can be downloaded from:
http://www.vatvalve.com/customer-service/informations-and-downloads/control-performance-analyzer.
Alternatively the VAT Service Box2 can be connected to the service port for setup and local operation.
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 chapter: «Local Operation» for details and to chapter «Spare parts / Accessories» for
ordering numbers of service cable, software and Service Box 2.
Use only screws with 4–40 UNC thread for fastening the service port connector.
