11.43 "Multipump setup" (Setup of multi-pump system)
Pump variant
NBE, NBSE, NKE, TPE, TPED
NBE, NBSE, NKE, TPE, TPED
Series 2000
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.
11.43.1 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.
