Got 5 flashes on inverter. Tested compressor windings 1.4 ohm between phases all balanced and nothing down to earth. Didnt megger. Tested inverter with compressor disconnected and lights flash for few seconds then all leds just stay on. Is this okay? Ive tested other inverters and the leds all keep flashing.
Amps on each phase ramps to 12A with compressor connected then board cuts power.
Should the led lights stay on or flash? I thought maybe the board quickly ramps to full speed so it flashes for few seconds from startup and then suddenly just stays on as the frequency is to high to see the flashes. Any thoughts on this? The compressor have been changed once the client says.
All faults indicate locked compressor, but the windings test okay with multimeter and the constant on led on inverter checker im not sure of. Cant decide if its the board or the compressor. Any other way to check to verify?
