Inverter LED D302 Information
LED D302
LED D302 blinks at 1Hz to indicate that the Inverter is running
correctly.
When it blinks at any other rate, it indicates there is an
abnormal state of the Inverter.
When it doesn't blink, check the 24V arriving at the board on
CN1 pins 1~5.
Check the two fuses F1 and F2 for 24V.
Check IC302 and IC303 regulator voltages (see page 56).
