What is the tbS setting and status on an ATS48 soft start?
Issue:
TBS function on the ATS48 softstart
Product Line:
Altistart 48, ATS48
Environment:
All models and serial numbers
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 start/run circuit.
