What to check if my Solcon Controller trips with S. SCR OR WR. CONNECTION error?
- SSierra HendrixSep 8, 2025
If the Solcon Controller trips due to S. SCR OR WR. CONNECTION, it means one or more motor phases are not properly connected to the starter’s load terminals, in case of internal disconnection in motor winding or if any SCR is short-circuited or when motor windings are shorted. Check with an ohmmeter between L1-U, L2-V, L3-W; is the resistance > 20 K? Also, check for no voltage on terminals U, V, W.
