Start-Up
Internal Timer
This macro configures for applications where a built-in timer starts and stops the
motor. When the variable speed pump reaches a maximum speed limit, auxiliary
pumps start as needed. When using direct speed reference in AUTO mode or
process PID, see "General Considerations" on page 30.
Momentarily activating digital input 3 (DI3) provides a boost function which operates
the motor. See group 36, Timer Functions, for more information on setting up timers.
