Functional Description

IC3606SASB1A is an over-temperature Card developed by GE. It is a part of Mark I and II control system. It is responsible for monitoring temperature signals, typically exhaust or combustor temperatures and triggering a response when readings exceed safe operating thresholds. When an over-temperature condition is detected, the card initiates a fuel cutback or system alarm to prevent further temperature rise and potential damage to turbine components such as nozzles, blades, or combustion liners.

Features

• Temperature Monitoring: Continuously receives temperature input signals for evaluation.
• Threshold Comparison: Built-in logic compares actual readings against preset limits.
• Protective Action Triggering: Sends signals to initiate fuel cutback or generate alarms upon over-temperature detection.
• Compatibility: Specifically engineered for integration within the Mark I and II SPEEDTRONIC control racks.
• Reliability: Designed with industrial-grade components for continuous, high-reliability operation in harsh turbine environments.

Integration with System Features

• Minimum VCE (Valve Command Equivalent) System: This feature ensures that during fuel cutback, whether triggered by temperature, speed, or other protective inputs—the fuel flow does not drop below a minimum threshold. This prevents flame-out by maintaining enough fuel for combustion while still reducing the turbine load to mitigate the over-temperature condition.
• Manual VCE Control: The system allows an operator or start-up technician to manually control the VCE, giving them direct influence over fuel flow during start-up, troubleshooting, or special operating conditions. Even when manual VCE is engaged, the system's protective logic (including inputs from the over-temperature card) remains active and can override manual inputs to protect the turbine.

This dual control approach—manual flexibility combined with automatic protection—makes the Mark I and II systems robust for a variety of operating scenarios, from initial turbine commissioning to long-term automated operation.

FREQUENTLY ASKED QUESTIONS

What is IC3606SASB1A?
It is an Over-temperature Card developed by GE.

What is VCE and how is it related to this card?
VCE (Valve Command Equivalent) refers to the control logic for fuel flow. The over-temperature card interacts with the VCE system to reduce fuel during high-temperature conditions. The Minimum VCE logic ensures fuel is not cut back so much that the flame extinguishes.

Can operators override the over-temperature function?
Operators can use Manual VCE control during startup or troubleshooting, but protective functions like over-temperature cutback still operate through priority logic to protect the turbine from unsafe conditions.
