System LED Conventions

• Indicating Voltage Levels: LEDs are employed to signify the voltage levels within the system. In this convention, an LED illuminates to indicate a high voltage level, which corresponds to a logic 1 state. Conversely, the LED turns off to represent a zero or low voltage level, signifying a logic 0 state.
• Red LED for Trip State: A red LED is specifically designated to indicate a trip state, which corresponds to a high voltage level. When the red LED is illuminated, it communicates that the represented signal is in the trip condition. This convention is crucial for promptly identifying and responding to critical situations.
• Green LED for Run Condition: In contrast to the red LED, a green LED is used to signify a run condition, associated with a high voltage level. When the green LED is on, it communicates that the system is in a run state. Conversely, it turns off to indicate a trip condition characterized by a low voltage level. This clear distinction simplifies the interpretation of the system's operational status.
• Yellow LED for Transitional Signals: Yellow LEDs are specifically employed to monitor signals whose trip status changes as the turbine undergoes transitions during its operational sequence. For instance, during turbine start-up, the overspeed signal typically remains in the high voltage state (illuminated). However, as the turbine's speed surpasses the threshold required to trigger the 14HS signal (becoming logic 1), the overspeed signal switches to a low voltage state (LED off). When the turbine operates at speeds exceeding 14HS, yellow LEDs are used to indicate a tripped condition. This nuanced use of yellow LEDs offers a dynamic way to monitor changing conditions during the turbine's operation.

FREQUENTLY ASKED QUESTIONS

What is IC3603A277C?
It is a Thermocouple AVG Module developed by GE

How do LEDs indicate different voltage levels in turbine control systems?
LEDs use a clear convention where they illuminate to signify a high voltage level, corresponding to a logic 1 state. In contrast, they turn off to represent a zero or low voltage level, which signifies a logic 0 state.

What is the significance of the red LED?
A red LED serves a specific purpose by indicating a trip state, which corresponds to a high voltage level. When the red LED is illuminated, it communicates that the represented signal is in the trip condition. This serves as a critical alert for promptly identifying and responding to critical situations within the control system.

How is a green LED utilized in the context of turbine control systems?
In contrast to the red LED, a green LED signifies a run condition associated with a high voltage level. When the green LED is on, it communicates that the system is in a run state, indicating normal operation. The green LED turns off to indicate a trip condition characterized by a low voltage level. This distinction simplifies the interpretation of the system's operational status.
