3 Operation
Operation is allowed after completion of the installation procedure only.
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 using a computer or the Service Box 2. When using
a computer, a service cable and a software from VAT are required. You can either download our freeware 'Control View'
from
www.vatvalve.com
or purchase our 'Control Performance Analyzer'.
These software 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:

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.
Refer to «Spare parts / Accessories» for ordering numbers of service cable, software and Service Box 2.
