The scenario
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.
What is in this drawing
Read the decisions behind it.
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.
