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, such
as 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.
17.49.1
Alternating operation
Alternating operation functions as a duty-standby
operating mode and is possible with two pumps of
same size and type connected in parallel. The main
purpose of the function is to ensure an even amount
of running hours and to ensure that the standby pump
takes over if the running pump stops due to an alarm.
Each pump requires a non-return valve in series with
the pump.
You can choose between two alternating operation
modes:
• Alternating operation, time Pump changeover to
the other is based on time.
• Alternating operation, energy Pump changeover
to the other is based on energy consumption.
If the duty pump fails, the other pump takes over
automatically.
17.49.2 Backup operation
Backup operation is possible with two pumps of same
size and type connected in parallel. Each pump
requires a non-return valve in series with the pump.
One pump is operating continuously. The backup
pump is operated for a short time each day to prevent
seizing up. If the duty pump stops due to a fault, the
backup pump starts automatically.
