3.24 PC-## Pump Controller

Parameters for configuring the basic Pump Controller for sequence control of multiple pumps. For a more application-
oriented description and wiring examples, see Application Examples, Pump Controller in the design guide.
To configure the Pump Controller to the actual system and the desired control strategy, follow the sequence starting with
3 3
parameter group PC-0# System Settings and next parameter group PC-5# Alternation Settings. These parameters can normally
be set in advance.
Parameters in parameter group PC-2# Bandwidth Settings and PC-4# Staging Settings often depend on the dynamic of the
system and final adjustment to be done at the commissioning of the plant.
NOTICE
The Pump Controller is supposed to operate in closed loop controlled by the built-in PI controller ([3] closed loop
selected in parameter H-40 Configuration Mode). If [0] open loop is selected in parameter H-40 Configuration Mode, all
fixed speed pumps are destaged, but the variable speed pump is still controlled by the frequency converter, now as an
open-loop configuration:
