4.5.6 Power connection for Slave valve only
[642 . . - . . . S - . . . . or valves configured as slave]
• Do not connect other pins as shown above that may damage power supply or controller!
• Connector: Use only screws with 4–40 UNC thread for fastening the connectors!
4.5.7 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 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 «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.
Pins 4 and 8 must be
bridged for operation.
An optional switch
would allow for motor
interlock to prevent
valve from moving.
