How do I know if my CouplerTec electronic rust-proofing system is operating correctly?

The system only operates correctly and effectively if each capacitive coupler has its own internal circuit with a required level of voltage, frequency and capacitance. If the module is working correctly, a green light is flashing. If the system detects a fault, a red light is flashing. The system will automatically reset after the fault has been rectified.
