Start-Up
Pump Alternation
This macro configures for pump alternation applications, usually used in booster
stations. To adjust/maintain pressure in the network, the speed of the one pump
changes according to a signal received from a pressure transducer. When the
variable speed pump reaches a maximum speed limit, auxiliary pumps start as
needed. When using process PID, see "General Considerations" on page 30. To use
more than one (the default) Auxiliary pump, see parameter group 81.
