Speedtronic Mark V Maintenance

Back to seminars

Overview:

The 5-day Maintenance course is designed for experienced instrument personnel involved in the daily maintenance of the Mark V control systems and HMI. The course will enable the instrument technician / Engineer to configure HMI displays and confidently, manipulate HMI software tools as well as diagnose problems in Gas Turbine SPEEDTRONIC Mark V Control Systems. The course is designed to provide a solid background in turbine governing systems. Participants increase their skills in IDOS & HMI features, configuration and troubleshooting.
