Goals and Symptoms
We have a softstarter ATS48C48Q that is displaying the OCF code. We followed the instruction on User´s Manual : Checking the motor and wire isolation, by-pass circuits testing, and the others recommendations. We did not find anything that explains the situation. The OCF code is displayed randomly, in anytime, inclusive without the RUN command order and without main power supply on L1-L2-L3 . Could you say us what another causes are possible? We already have changed the control board, but the result is the same : the OCF code continues displaying.
