3-7 Multiple Pump
Configuration
3-7-1 Role in Multiple Pump
System
Selecting the role of the frequency inverter
in a multiple pump configuration. The
active master control device is responsible
for starting and stopping pumps, as well as
for open-loop and closed-loop control. All
input variables required for open-loop or
closed-loop control must be connected to
the master control device and all redundant
master control devices. The redundant
master control device which is to serve as
active master control is selected
automatically based on a configurable
transfer time. Auxiliary control and
redundant master control devices receive
the manual-mode control value from the
master control device.
