FUNCTIONAL DESCRIPTION:

IC3600SGDE1A is a Ground Fault Detector Card manufactured and designed by GE Mark I & II Series as part of the GE Speedtronic Gas Turbine Control Systems. The GFD Ground Fault Detector is used to detect ground faults on power-limited isolated circuits. The GFD provides ground fault monitoring for up to two isolated signals. A ground fault on any wire is detected within 20 seconds. Built-in relay contacts are available for indicating trouble and ground fault conditions, or the GFD can be configured to put a ground fault on the monitoring circuit. The GFD is a stand-alone unit. Its dry contacts can be monitored by other system input devices. The GFD also has a watchdog circuit, which keeps the relay energized. When JP1 is in the 1-2 position, the GFD connects the COM output (terminal 3 of the terminal block) to earth ground through a 1 k Ohms resistor. The COM output can be connected to the minus side of the input power or supervisory module so that a ground fault can be transferred to the panel.

INSTALLATION:

Install the Ground Fault Detector Card with the system power OFF. Insert the card into the designated backplane slot, ensuring full engagement of the edge connector, and secure with mounting screws or retention clips. Connect all required wiring, including CT inputs, ground fault detection inputs, and alarm/trip outputs, following the system wiring diagram. Power up the system and verify correct operation using status LEDs and diagnostics, performing functional tests as required.

• Power Isolation: Ensure the PLC or control system rack power is fully turned OFF. Verify that no residual voltage is present in the backplane or wiring circuits.
• Slot Identification: Locate the designated slot in the backplane for the Ground Fault Detector Card as specified in the system documentation. Confirm compatibility with adjacent modules to prevent bus conflicts.
• Card Insertion: Align the card edge connector with the backplane slot guide. Insert the card vertically, applying uniform pressure to ensure full engagement of all connector pins. Avoid excessive force to prevent damage to the backplane or card connectors.
• Mechanical Securing: Fasten the card using the provided mounting screws or retention clips at the top and bottom tabs to prevent movement due to vibration or handling.

KEY FUNCTIONS:

The Ground Fault Detector Card continuously monitors electrical circuits for leakage currents that indicate ground faults, measuring the imbalance between phase and neutral currents. When a fault exceeds a preset threshold, the card generates an alarm or trip signal to the PLC or control system, enabling rapid response to protect equipment and personnel. It provides diagnostic information through status LEDs and test points, allowing verification and troubleshooting. The card integrates seamlessly with industrial control systems to support automated monitoring, fault reporting, and system safety functions.

• Continuously monitors electrical circuits for ground faults by detecting leakage currents.
• Measures the imbalance between phase and neutral currents to identify faults.
• Provides alarm or trip signals to the PLC or control system when fault thresholds are exceeded.
• Interfaces with PLCs or protection relays for real-time fault status reporting.
• Supports diagnostic outputs, including status LEDs and test points for verification.
• Enables rapid fault detection and system shutdown to protect equipment and personnel.
• Integrates with industrial control systems for automated monitoring and fault management.

FREQUENTLY ASKED QUESTIONS:

What is the primary function of the Ground Fault Detector Card?

The card continuously monitors electrical circuits for leakage currents by detecting imbalances between phase and neutral currents. When a fault exceeds a preset threshold, it generates an alarm or trip signal. This allows the control system to respond quickly and protect equipment and personnel.

How is the card installed in the system?

Installation requires the system power to be OFF. The card is inserted into the designated backplane slot and fully seated. It is then secured with screws or retention clips, and all necessary wiring for CT inputs, ground fault detection inputs, and alarm/trip outputs is connected according to the wiring diagram.

What are the diagnostic features of the card?

The card provides status LEDs and test points to indicate operational status and detect faults. These diagnostics allow maintenance personnel to verify correct operation and troubleshoot issues efficiently. It ensures that any ground faults are quickly identified and addressed.
