7.44 Multi-pump 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 up via a selected pump, i.e. the master
pump (first selected pump).
If two pumps in the system are configured with a
discharge-pressure sensor, they can all function as master
pumps and take over the master pump function if the other should
fail. This provides additional redundancy in the multipump
system.
The multipump functions are described in the following sections.
7.44.1 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
Change from one pump to the other is based on time.
• Alternating operation, energy
Change from one pump to the other is based on energy
consumption.
If the duty pump fails, the other pump will take over automatically.
7.44.2 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 will start
automatically.
