Maintenance
Typical maintenance methods and testing procedures are offered as learning content. Some of the exercises take a lot of time to complete and amount to substantial project work. Demands are made on technical skills.
GUNT DigiSkills 3: Preventive maintenance
Nowadays, production plants have a 24/7 availability. Predictive maintenance enables this continuous operation.
