7.1.3.2 Configuration example
The following parameterisation example applies to a multiple pump configuration
with a main pump, an auxiliary main pump and a slave pump. The PumpDrives used
are equipped as follows:
Table 62: Multiple pump configuration example
PumpDrive Role Control panel
1 Main pump with active master control panel Advanced
2 Auxiliary main pump with auxiliary master control panel Advanced
3 Slave pump Standard
The parameter settings of the individual PumpDrives have to be made/checked as
follows:
Parameterise PumpDrive1 with active master control panel
Table 63: Configuration example for multiple pump operation: PumpDrive 1
Parameter Description Value
3-1-7-4 Time value for identifying the control panel as the active master
control panel
1.0 s
3-2-1-1 Role in multiple pump configuration Auxiliary main pump
3-2-1-2 PumpDrive ID 1
3-7-1-2 Function of digital input 2 System start
3-10-1-3 Time value for identifying the control panel as the main pump 2.5 s
3-12-5-1 Maximum number of pumps running simultaneously 2
3-12-5-5 Pump changeover Enabled
Parameterise PumpDrive 3 using the active master control panel of PumpDrive 1:
