If the LED is red and blinking quickly	CT’s maximum current rating has been exceeded
If the LED does not blink	Check fuses and voltage connections. STATUS LED should blink regardless of CTs, Modbus connections, and DIP switch settings.
If the LED does not blink.	When the unit is wired on the load side of an adjustable frequency drive and the LED does not blink, the unit’s thermal fuse could be blown. The unit must not be installed on the load side of an adjustable frequency drive.
