3 Operation
3.1 Introduction
This valve is designed for downstream pressure control in vacuum chambers. It can be employed in a pressure control
mode or a position control mode.
In both cases local or remote operation is possible.
3.1.1 Local operation
Local operation means that the valve is operated via the service port by means of a computer. A service cable and a
software from VAT is required. You can either download our freeware 'Control View' from www.vatvalve.com
or purchase
our 'Control Performance Analyzer'.
These softwares are beneficial especially for setup, testing and maintenance.
How to start: Connect service cable, start software and push button ‘LOCAL’ to enable for operation. Then enter menu
Setup/Sensor and do sensor configuration according to your application to make sure that you get the correct pressure
displayed.
‘Control view’ supports:
- parameter setup
- manual control
- numeric monitoring
- basic diagnostic
'Control Performance Analyzer' supports:
- parameter setup
- manual control
- sequence control
- numeric and graphical
monitoring
- data recording
- data analysis
- advanced diagnostic
Note: 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.
Refer to «7 Spare parts and accessories» for ordering numbers of service cable and software.
