Control Systems
VPT’s Control Systems are well known for their proven reliability in a multitude of custom vacuum equipment applications. System options cover a wide range of control complexity from a simple, manual operation to fully automatic, PC based packages. VPT also designs and manufactures dedicated, self-contained control units for specific applications such as pumping sequencers, regeneration controls and planetary drive systems.

The standard VPT Control System is PLC (programmable logic controller) based and provides manual and semiautomatic operation. The PLC is the key component of the control system, interfacing with all system components and providing vital sequencing and interlocking capabilities. An optional PC control system utilizes the PLC platform and HMI operator interface package to provide specific graphic screens on the computer for system control and process variable input.

Multiple process recipes can be developed, stored and run as dictated by production requirements. Manual and automatic modes are included for initial process development and optimization. The PC also includes data logging capability as well as a historical database for alarms and operator induced functions. Real time trending of various system variables is also a feature of this software package.
