1. Normal start rung, KG1 initiates start through the SMC Flex module at
Term 16.
2. M closes, motor accelerates, the Up to Speed contact within the SMC Flex
module between terminal 19 and 20 closes, B closes.
3. B, KG3 and KG1 then close KG4 to apply PFCC.
4. If option stop, KG1 opens KG4 immediately to drop out PFCC, and
command SMC to stop.
5. CC holds in B until CC drops out, then permits B to open, option stop
continues.
6. If a coast stop is initiated, the Flex will open the contact between 20 and
34; KG3 will open M and command KG4 to open CC. CC will hold B
