6. LED display on inverter PCB
According to the position of SW01, the 4 LED (D25~D28) of frequency conversion can express the following content:
(1) If the LED displaying <IGBT short circuit> protection has no abnormal locking, when shortening time, it will
flicker in 5 Hz frequency.
(2) When conducting protection action, the LED displaying protection function will flicker in 5 Hz frequency, other
LED will be lighted.
For example: IGBT short
circuit protection action
Current detection circuit
protection action
(3) Do not display the number of protection action of high pressure
