Issue:
What are the steps to troubleshoot an OSF [Over Supply Fault] on an ATS22 soft start?
Product Line:
ALTISTART 22, ATS22
Environment:
All
Cause:
Over voltage condition
Resolution:
Overvoltage fault.
Check ULN parameter under CONF menu. This should match your line voltage.
Check the power supply circuit and voltage. Reading will need to be balanced phase to phase on L1, L2, and L3 and match voltage spec for the softstart and motor.
Check OSD [Over voltage Threshold] and OST [Over voltage Time Delay] parameters in PRO menu for possible adjustments.
