A pilot signal detection and indication unit includes a pilot signal scaling unit structured to generate a scaled pilot signal by shifting a pilot signal using a bias voltage and scaling down the pilot signal, a pilot signal duty cycle comparator unit structured to generate a limited pilot signal that has a fixed peak voltage and a duty cycle that is equivalent to the duty cycle of the pilot signal, a processing unit structured to determine a voltage value and the duty cycle value of the pilot signal from the scaled pilot signal and the limited pilot signal, and to generate an indication signal based on the determined voltage value and duty cycle value, and an indication unit having a number of indicators and being structured to activate selected ones of the number of indicators based on the indication signal.
