PWR LED (Green) - Indicates condition of DC input power or a “Wink” command.

Always On: Correct DC input power is present.

Flashing Continuously: DC input to module is below minimum required voltage.

Flashes for 2 Seconds: A “Wink” network management command has been sent to the Control
Neuron Processor.
ERR LED (Red) – Indicates a possible error condition.

Always On: A diagnostic error has been detected. Press the “RESET” button. If the “ERR” LED now
stays off, the EEPROM contained invalid data and has been reinitialized. Any non-volatile
