What can cause an OHF on the ATS46 soft starters?
The soft starter is overheating
OHF is an overheating fault. Power down the soft starter and let it cool down. Power back up and if the fault clears run the soft starter. If the fault comes back up then you may have a bad thermal sensor or main control board.
