Hi Imran, thank-you for the well wishes, she is doing better and should make a full recovery thankfully.?
1&2. Seems you are correct about the switched labels, continuity tests prove that 1F2 is L1 and 1F3 is L3, primary feed. 1F4 should be a 2A fuse on 24VAC. I reinstalled fuses and replaced the blown ones. I replaced 1F1 thermal overload relay aswell with a new one that is functioning properly¡ Applied power to see if that may have fixed it, but 1F3 immediately blew again.
3. Removed 1F4 2A fuse, replaced 1F3 fuse and applied power. 1F3 blew again immediately but tested for 24VAC anyways, no power (makes sense considering 1F3 was blown). Shut off the power again for testing.
4. Wasn¡¯t quite sure what you were referring to on this, but I assumed you were talking about the 230VAC side of the terminal blocks, checked continuity, no continuity from 1 to 2, had continuity from 3 to 4, and no continuity again from 5 to 6. Please correct me if you meant something else.?
When power is applied to the machine all of the contactors remain open. If I manually depress contactor 1K1 the SMD inverter powers up and the planer feed runs, variable speed works fine. If I manually depress contactors 1K1 and 1K3 the cutter head power up and seems to run fine. I know this is probably not recommended but I wanted to ensure the motor¡¯s and inverter were still functioning properly.?
?I double checked again that there was no short to ground on the 230VAC system, specifically from L3 considering that fuse keeps blowing. Still no continuity to ground on any leg, or from any of the fuses besides 1F4 on the 24VAC system?
Not quite sure what else could be causing it, any ideas of where to look next would be appreciated.?
Thankyou for the help
Best regards,?
Andrew
