- Engineered for high-velocity signal processing to detect overcurrent, phase shifts, and phase imbalances
Application Scenarios: Heavy industrial applications requiring continuous monitoring of electrical current parameters, including thermal power plants, petrochemical refineries, large-scale mining operations, power generation, turbine control systems, and large-scale motor drive management.
Installation Requirements:
- Ensure the control system is powered down before inserting or removing the board from the rack
- Handle the module using proper ESD precautions
- Verify that all field wiring is properly terminated and shielded to minimize EMI interference
- Ensure the module is fully seated in the designated Mark V slot and secured using the provided locking mechanisms
- Use the front-panel test points to verify signal integrity and calibration after installation
Usage Notes: This module is specifically engineered for the GE Fanuc Mark V Speedtronic control system and is not intended for use in other control series. If the module reports a fault, use the front-panel test points to check the CT loop health and verify that jumper settings are correctly configured.
