There are 3 LEDs that indicate the 3 modes. MPPT LED (MPPT) – Maximum Peak Power Tracking - Indicates the Energy Processor is adjusting the input im- pedance to match the transducer impedance. Any time the Energy Processor is performing the MPPT function, the LED will flash momentarily (1 millisecond). The LED will be lit momentarily every time the Energy Processor enters this state or when the push button is pressed. To force MPPT state, hold S2 while connecting the EH transducer. When MPPT LED flashes, release push button switch S2. Target system MCU or SW1 changes can also force MPPT. Output Holding Cap Charge LED (CAP) – This indicates the capacitor used to hold output charge for the target load is being charged. The CAP LED will be lit momentarily every time the Energy Processor enters this state on its own, and in response to pressing S2 if in this state. EnerChip Charge LED (EC) - This indicates the EnerChip devices are being charged and power is turned on to the load. The LED will be lit momentarily every time the Energy Processor enters this state, and state indicates the EnerChips are being charged, but the system is not yet in regulation (e.g., due to insufficient power being available). Charge Sequence Complete - Independent of the push button, once the Energy Processor has completed the sequence of MPPT, Cap Charge and EnerChip Charge, all three LEDs will be flashed for 1 millisecond. In this state, system is in regulation. EVAL-09 Output Power Disconnect – In order to remove the output voltage from the target load, press switch S2 and hold for 5 seconds. Initially all three LEDs will flash (if the system was in regulation), or the EC LED will flash (if the system was out of regulation). After 5 seconds, Cap Charge and EC Charge LEDs will flash, indicat- ing the output voltage has been disconnected. A momentary press of switch S2 will indicate state information after the power has been disconnected from the load. EVAL-09 Output Power Reconnect - In order apply output voltage to the target load, press switch S2 and hold for 5 seconds. Initially all three LEDs will flash (if the system was in regulation), or the EC and MPPT LEDs will flash (if the system was out of regulation). After 5 seconds, Cap Charge and EC Charge LEDS will flash, indicat- ing the output voltage has been reconnected. |
