What does “tBS” mean in case of ATS22 or ATS48 soft-starter. Does it indicate fault state of soft-starter.
“tBS” does not indicate any fault state of soft-starter but as it name suggests it is “Time before re-starting”.
It can be set in unit of seconds. The moment soft-starter is STOPPED from that moment time count is started
as set in tBS. If during this period START command is issued to the soft-starter, soft-starter will abort START
command and will not be started. As soon as tBS- time value elapsed, starter move to RDY status and thereafter
only it will be ready to start.
