Issue:
Why does the ATS480 Softstarter trip on PHF3, Phase Loss Error after a run command?
Product Line:
ATS480

Resolution:
PHF3 is Phase loss error. If the motor current in one or more phases is below the threshold set in [Phase Loss Thd] PHL parameter, the soft starter triggers the [Phase Loss] PHF3 error.

Causes:
• Loss of one or several phases on mains or motor side
• Soft starter incorrectly supplied or tripped fuses.
• Defective motor
• Defective wiring on the motor or the supply mains
Remedy:
• Verify the threshold set in [Phase Loss Thd] PHL is compatible with the motor. Set PHL to 5% and try again.
• Verify the motor supply wiring and any devices located between the mains and the soft starter
(contactor, fuses, circuit-breaker,...)
• Verify the motor
Clearing the Error Code:
This detected error is automatically cleared with the [Auto Fault Reset] ATR or manually with the
[Fault Reset Assign] RSF parameter after its cause has been removed.
