Protection item Operation (trip) time

Overcurrent = O-time

Phase loss = O-time

Stuck rotor = D-time + O-time

Ammeter function:

After the motor is running smoothly, slowly turn the overcurrent setting knob counterclockwise until the red indicator lights up, indicating 100% of the actual operating current. Turn the knob clockwise again until the red light just turns off, indicating approximately 103% of the actual operating current. Operation/Operation Indicator:
