Issue:
ATS46 soft starters overheating.
Product Line:
Altistart ATS46
Environment:
All
Cause:
The soft starter is overheating
Resolution:
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. All of these parts are all now obsoleted. Would suggest to replace the ATS46 series soft starter with a ATS48 soft starter.
