5.1.1  Local operation 
Local operation means that the valve is operated via the service port using a computer or the Service Box 
2. When using a computer, a service cable and a software from VAT is required. 
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. 
 
These softwares are beneficial especially for setup, testing and maintenance. 
 
How to start: 
Connect service cable between PC and valve controller, start software and push button ‘LOCAL’ to 
enable for operation. Then enter menu Sensor / Setup and do sensor configuration according to your 
application to make sure that you get the correct pressure displayed.

'Control Performance 
Analyzer' supports: 
  Valve setup 
  Sensor setup 
  Pressure control 
  Interface setup 
  Manual control 
  Sequence ontrol 
  Numeric and

When communication to service port is interrupted the valve will change to remote 
operation. So when service cable will be disconnected or software will be shut down, 
the valve returns automatically to remote operation. This may result in an immediate 
movement of the valve depending on remote control.
