Functional Description

IC3600QEAA1D is a Differential Amplifier Card developed by GE. It is a part of Mark I and II control system. The purpose of the card is to amplify differential input signals, the voltage difference between two inputs, while rejecting any common-mode noise or interference. This makes it especially valuable in industrial turbine environments where electrical noise from nearby equipment, grounding differences, or long cable runs can affect signal accuracy.

Operational Insight for the Operator

These indicator lights are designed to assist the operator in tracking the transition through various operational stages of the gas turbine. They provide the following visual cues:

• Start-Up Mode: When the turbine is in start-up control, a corresponding light is illuminated, confirming that the unit is initiating its warm-up sequence.
• Suppressed Temperature Control: As the turbine ramps up, the suppressed temperature mode takes over. An indicator signals this transition, confirming temperature regulation has begun to override acceleration control.
• Acceleration Control: When the turbine enters the acceleration control phase, another light confirms that the unit is being governed based on its acceleration profile.
• Speed Governor Mode: Once the turbine reaches operational speed, the system shifts to speed governing mode. The appropriate indicator lights up to signify this condition.
• Full Load Temperature Control: After the operator has loaded the turbine—either manually or through automatic loading systems—to its full capacity relative to the ambient conditions, a red temperature control light is triggered. This signifies that the turbine has reached maximum permissible power output for the current temperature environment.

FREQUENTLY ASKED QUESTIONS

What is IC3600QEAA1D?
It is a Differential Amplifier Card developed by GE.

Where are the control mode indicator lights located?
Physically, they are located on the front of the control panel. Electrically, they are integrated into the major input circuits such as the acceleration loop, speed governor, and temperature loop. Remote indication options are also available.

Can operators monitor these lights remotely?
Yes. The system is designed with provisions for remote indication, allowing operators to monitor the turbine’s control mode from centralized control rooms or monitoring stations.
