How does the Altistart ATS46 starter react to undervoltage?

There is not a specific undervoltage fault. The nominal voltage range is for three-phase supply voltage
208 V -10% to 240 V +10%
380 V -15% to 415 V +10%
440 V -10% to 500 V +10%
If the mains do not get voltage within 200 mS of a run command then there will be USF (Supply) fault.
Also, it is possible to have PHF (Phase Fault) if the voltage is not within the normal range or if it drops suddenly while attempting to run the motor.
