Duration
Four training days
Location
Tampere, Finland
Description
The attendees are introduced to following high level controls: Oven Dry weight, Paper ash, Headbox ash, White water consistency andĀ  Moisture. The controls are detailed through the use of theory and a Valmet DNA simulator. Valmet DNA low level loops and PID tuning are also covered.
Objective
This course provides a review of the theory and algorithms of Valmet IQ MD Controls machine direction multivariable. After the course, the participant should be familiar with the Valmet IQ Metso IQ MD Controls product and be able to evaluate the process and the current MD control performance as well as maintain the MD control tuning.
Audience
QCS maintenance personnel
Pre-requisites
Valmet DNA operator skills
