About the 565-5-5-A

Part of the 565 series, the 565-5-5-A is a digital feeder management relay produced by General Electric Multilin. This relay has a phase CT rating of 5 amps and a ground CT rating of 5 amps. The control volts are 90-260 V AC and 95-280 V DC. Protective features include ground current protection and time/overcurrent phase protection. Relay testing on this unit involves the power loss check, the analog output function check, the overvoltage trip and alarm check, the analog input function check, the undervoltage trip and alarm check, the output relay functional check, the voltage input function check, the ground curve verification, the ground instantaneous pickup and trip check, the ground current input function check, the phase overcurrent curve verification, the phase current input function check, and more.

Troubleshooting is simple on the digital feeder management relay; simply follow the instructions that are listed in the user instruction manual in the troubleshooting section beginning on page B-1. If the display does not light up, ensure that the relay is fully inserted into the drawout case, and check the control power voltage and the control power fuses. For reference, refer to the relay wiring diagram in the user instruction manual. If a message does not appear when the display lights up, check that the control voltage is within the correct limits. If the incorrect phase current readings are displayed, use a clamp-on ammeter to measure the current flowing into the 565 CT terminals. The correct phase CT primary rating must be entered by the user into setpoints for the correct phase current readings to be displayed.
