What causes tbS state on the ATS46 and ATS48 soft starter?
Issue:
Display shows tbS
Product Line:
ATS46
Environment:
All models and serial numbers
Cause:
Time before starting. An attempt to restart was made prior to the preset time entered in parameter tbS.
Resolution:
Increase the time in parameter tbS or wait until the time value of tbS has expired.
The tbS parameter avoids starts in quick succession which may overheat the motor.
It's adjustable between 0 and 999 seconds. Factory default is 2 seconds.
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 I>; during the time delay.
