What would cause the ATS22 to keep tripping the shunt trip breaker and not allow you to reset a simple OLF overload error?

Resolution:
You can temporarily remove the wire from the ATS22 terminal R2B to temporarily deactivate the shunt trip feature.   Now the Soft starter will stay powered up, time out and then allow the fault to be reset.  If the timeout is not important to cool the motor, you can manually reset the OLF by going into the PRO menu and setting ItH = OFF, then power cycling the soft starter and then setting ItH = ON. This resets the thermal memory.  Reconnect the R2B terminal wire.

It is VERY important that the wiring is returned to it's previous state once the error has been reset, since the shunt trip breaker is an important means of isolating line power from the softstart in order to protect the motor.
