Functional Description

5462-750 is a Secondary Power Supply Module developed by Woodward. In the event of a primary power source failure or any other power-related issues, this module seamlessly takes over and supplies the necessary power to ensure uninterrupted operation. This feature is crucial in maintaining the stability and reliability of the gas turbine control system, safeguarding it against potential disruptions and failures. The Secondary Power Supply Module incorporates advanced features and safety mechanisms. It incorporates monitoring and diagnostic capabilities to detect and report any abnormalities or faults promptly. The module's seamless integration into the gas turbine control system architecture simplifies installation and maintenance procedures.

System Power-up

1. Make sure the entire MicroNet TMR control system is installed.
2. Turn on one power supply and ensure that the green LED on the power supply is the only one that is lit.
3. Turn on the second power supply and ensure that the green LED on the power supply is the only one that is lit.
4. Ensure that all of the Kernel Power Supply's red fault LEDs are turned off. If any of the LEDs are illuminated, refer to Section 4.8 for Kernel Power Supply Troubleshooting. 2. If the system is configured with the CPU 040, skip step #5 and proceed to step #6. If the CPU 5200 is used in the TMR system, skip step 5 and proceed to step 6.
5. CPU 040: Toggle two of the CPU's RESET switches up briefly before returning them to their normal down position. Toggle the remaining CPU RESET switch to the up position, then back to the down position. The system will now perform off-line diagnostic testing, which may take several minutes. When all CPUs have synchronized and completed their diagnostic tests, there should be no red LEDs on the CPU modules or I/O modules, and the control will begin running the application program.
6. CPU 5200: Wait until the CPUs' off-line diagnostics are complete and the CPUs are visible in AppManager. If the CPUs were running when they were turned off, they will restart the application that was running when they were turned off. If no Applications were running, in AppManager, select an Application on each CPU and click "Start." The CPUs will execute the chosen application, synchronize, and finish their diagnostic tests. There should be no red LEDs on the CPU or I/O modules, and the application program should be running on the control. The Green SYSCON and RUN LEDs should be illuminated, while the Yellow STBY LED should be turned off.

Overtemperature LED

• This red LED alerts you to a potential thermal shutdown. The LED illuminates to indicate that the internal power supply temperature has risen above 80 °C. If the internal supply temperature exceeds 90 °C, the supply will shut down. There is no accurate way of predicting the time between the indication of overtemperature (LED illuminated) and power supply shutdown due to the many variables involved (ambient temperature, load, thermal conductivity variations).
• If this LED is illuminated, ensure that the fan in the power supply chassis is spinning and free of dust and other impediments, and that the temperature around the power supply is less than 55 °C.
• If the power supply is quickly cooled, it can recover from this situation without shutting down. When the internal power supply heat sink temperature falls below approximately 75 °C, this LED will turn off.

Frequently Asked Questions

What is 5462-750?
It is Secondary Power Supply Module developed by Woodward.

How do I check the status of the Kernel Power Supply?
Ensure that all of the Kernel Power Supply's red fault LEDs are turned off. If any of the LEDs are illuminated, refer to Section 4.8 for Kernel Power Supply Troubleshooting.

What steps should I follow for CPU 040 configuration?
Toggle two of the CPU's RESET switches up briefly before returning them to their normal down position. Toggle the remaining CPU RESET switch to the up position, then back to the down position. When all CPUs have synchronized and completed their tests, there should be no red LEDs on the CPU modules or I/O modules, and the control will begin running the application program.
