2.6.7 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', which can be
downloaded from
www.vatvalve.com
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 «Local Operation» for details and to «Spare parts / Accessories» for ordering numbers of service cable and
software.
Connector: Use only screws with 4-40UNC thread for fastening the service port connector!
Pins 4 and 8 must be
bridged for operation!
An optional switch would allow
for motor interlock to prevent
valve from moving.
