情境
Two motors start sequentially: pressing Start energizes relay K1 for motor 1, then timer KT1 delays before energizing relay K2 for motor 2. Stop or overloads drop the relays.

看懂背後的決策。
01
Use K1 seal-in with parallel Start contact
02
Use TON KT1 to create time delay
03
Use KT1 done bit to seal-in K2 with stop and overload interlocks
Use for staggered motor startup in relay control circuits where a time-delay relay must sequence a second motor after the first is running.
