Course Description


Control System - Woodward (Aero) Operation, Maintenance, & Troubleshooting


This course introduces plant maintenance personnel to the Woodward MicroNet™ and MicroNet Plus™ turbine control systems. These platforms have CPUs with an Ethernet port(s) and do not have a 2-line display. Course content includes the hardware layout of typical systems; from chassis to I/O cards to field termination modules. Course material provides training on Graphical Application Programmer (GAP) software navigation. Woodward software tools will be used to evaluate fuel control, sequence logic, and turbine-based alarms. Control actuator and other I/O calibration procedures will be discussed. Additional class work includes general information on the operator interface (HMI).
