What is the tbS setting and status on an ATS48 soft start?

Issue:
What is the tbS setting and status on an ATS48 soft start?

Product Line:
ATS48

Environment:
All models and serial numbers

Cause:
N/A

Resolution:
This parameter avoids starts in quick succession which may overheat the motor. The time delay starts when the motor changes to freewheel mode. 
In 2-wire control, the motor is restarted after the time delay if the RUN command input is
still activated. 
In 3-wire control, the motor is restarted after the time delay if a new RUN command is sent (rising edge).
The soft starter displays "tbS" during the time delay.

If tbS displays unexpectedly, check the run circuit.
