13.43 "Multipump setup" (Setup of
multi-pump system)
The multipump function enables the control of two
pumps connected in parallel without the use of
external controllers. The pumps in a multipump
system communicate with each other via the
wireless GENIair connection or the wired GENI
connection.
A multipump system is set via a selected pump, i.e.
the master pump, which is the first selected pump.
If two pumps in the system are configured with an
outlet-pressure sensor, both pumps can function as
master pumps and take over the master pump
function if the other fails. This provides additional
redundancy in the multipump system.
The multipump functions are described in the
following sections.
