PECe Maintenance Course
The course has been designed to familiarise electricians, technicians and maintenance engineers with the many different aspects associated with the operation and maintenance HPCi and PECe controllers .
Where possible, application specific exercises, actual drawings and programs listings are used to allow the students to gain the greatest possible benefit from the course.
HPCi and PECe courses are conducted by Digital Automation Training for GE Energy Rugby.
To introduce students to the concepts and operation of PECe controllers, including the following areas:
- PECe Hardware Overview.
- Program Structure
- Types of Variables
- Monitoring the program
- Addressing and documentation
- Monitoring Data
- Local and Global Variables
- Loading programs
- Fault finding
- The function of the elements used in a PECe drive, controller, PIBe, Power stack and I/O.
- Wiring, LED indication and operation of the PIBe.
- Understanding how the PIBe interfaces with the Thyristor stack.
